Along the Western Veil Image Credit & Copyright: Min Xie

Explanation: Delicate in appearance, these filaments of shocked, glowing gas, are draped across planet Earth’s sky toward the constellation of Cygnus. They form the western part of the Veil Nebula. The Veil Nebula itself is a large supernova remnant, an expanding cloud born of the death explosion of a massive star. Light from the original supernova explosion likely reached Earth over 5,000 years ago. Blasted out in the cataclysmic event, the interstellar shock wave plows through space sweeping up and exciting interstellar material. The glowing filaments are really more like long ripples in a sheet seen almost edge on, remarkably well separated into atomic hydrogen (red) and oxygen (blue-green) gas. Also known as the Cygnus Loop, the Veil Nebula now spans nearly 3 degrees or about 6 times the diameter of the full Moon. While that translates to over 70 light-years at its estimated distance of 1,500 light-years, this telescopic image of the western portion spans about half that distance. Brighter parts of the western Veil are recognized as separate nebulae, including The Witch’s Broom (NGC 6960) along the top of this view and Pickering’s Triangle (NGC 6979) below and left.

10 Things Einstein Got Right

One hundred years ago, on May 29, 1919, astronomers observed a total solar eclipse in an ambitious Ā effort to test Albert Einstein’s general theory of relativity by seeing it in action. Essentially, Einstein thought space and time were intertwined in an infinite ā€œfabric,ā€ like an outstretched blanket. A massive object such as the Sun bends the spacetime blanket with its gravity, such that light no longer travels in a straight line as it passes by the Sun.

This means the apparent positions of background stars seen close to the Sun in the sky – including during a solar eclipse – should seem slightly shifted in the absence of the Sun, because the Sun’s gravity bends light. But until the eclipse experiment, no one was able to test Einstein’s theory of general relativity, as no one could see stars near the Sun in the daytime otherwise.

The world celebrated the results of this eclipse experiment— a victory for Einstein, and the dawning of a new era of our understanding of the universe.

General relativity has many important consequences for what we see in the cosmos and how we make discoveries in deep space today. The same is true for Einstein’s slightly older theory, special relativity, with its widely celebrated equation E=mc². Here are 10 things that result from Einstein’s theories of relativity:

image

1. Universal Speed Limit

Einstein’s famous equation E=mc² contains ā€œc,ā€ the speed of light in a vacuum. Although light comes in many flavors – from the rainbow of colors humans can see to the radio waves that transmit spacecraft data – Einstein said all light must obey the speed limit of 186,000 miles (300,000 kilometers) per second. So, even if two particles of light carry very different amounts of energy, they will travel at the same speed.

This has been shown experimentally in space. In 2009, our Fermi Gamma-ray Space Telescope detected two photons at virtually the same moment, with one carrying a million times more energy than the other. They both came from a high-energy region near the collision of two neutron stars about 7 billion years ago. A neutron star is the highly dense remnant of a star that has exploded. While other theories posited that space-time itself has a ā€œfoamyā€ texture that might slow down more energetic particles, Fermi’s observations found in favor of Einstein.

image

2. Strong Lensing

Just like the Sun bends the light from distant stars that pass close to it, a massive object like a galaxy distorts the light from another object that is much farther away. In some cases, this phenomenon can actually help us unveil new galaxies. We say that the closer object acts like a ā€œlens,ā€ acting like a telescope that reveals the more distant object. Entire clusters of galaxies can be lensed and act as lenses, too.

When the lensing object appears close enough to the more distant object in the sky, we actually see multiple images of that faraway object. In 1979, scientists first observed a double image of a quasar, a very bright object at the center of a galaxy that involves a supermassive black hole feeding off a disk of inflowing gas. These apparent copies of the distant object change in brightness if the original object is changing, but not all at once, because of how space itself is bent by the foreground object’s gravity.

Sometimes, when a distant celestial object is precisely aligned with another object, we see light bent into an ā€œEinstein ringā€ or arc. In this image from our Hubble Space Telescope, the sweeping arc of light represents a distant galaxy that has been lensed, forming a ā€œsmiley faceā€ with other galaxies.

image

3. Weak Lensing

When a massive object acts as a lens for a farther object, but the objects are not specially aligned with respect to our view, only one image of the distant object is projected. This happens much more often. The closer object’s gravity makes the background object look larger and more stretched than it really is. This is called ā€œweak lensing.ā€

Weak lensing is very important for studying some of the biggest mysteries of the universe: dark matter and dark energy. Dark matter is an invisible material that only interacts with regular matter through gravity, and holds together entire galaxies and groups of galaxies like a cosmic glue. Dark energy behaves like the opposite of gravity, making objects recede from each other. Three upcoming observatories – Our Wide Field Infrared Survey Telescope, WFIRST, mission, the European-led Euclid space mission with NASA participation, and the ground-based Large Synoptic Survey Telescope — will be key players in this effort. By surveying distortions of weakly lensed galaxies across the universe, scientists can characterize the effects of these persistently puzzling phenomena.

Gravitational lensing in general will also enable NASA’s James Webb Space telescope to look for some of the very first stars and galaxies of the universe.

image

4. Microlensing

So far, we’ve been talking about giant objects acting like magnifying lenses for other giant objects. But stars can also ā€œlensā€ other stars, including stars that have planets around them. When light from a background star gets ā€œlensedā€ by a closer star in the foreground, there is an increase in the background star’s brightness. If that foreground star also has a planet orbiting it, then telescopes can detect an extra bump in the background star’s light, caused by the orbiting planet. This technique for finding exoplanets, which are planets around stars other than our own, is called ā€œmicrolensing.ā€

Our Spitzer Space Telescope, in collaboration with ground-based observatories, found an ā€œiceballā€ planet through microlensing. While microlensing has so far found less than 100 confirmed planets, Ā WFIRST could find more than 1,000 new exoplanets using this technique.

image

5. Black Holes

The very existence of black holes, extremely dense objects from which no light can escape, is a prediction of general relativity. They represent the most extreme distortions of the fabric of space-time, and are especially famous for how their immense gravity affects light in weird ways that only Einstein’s theory could explain.

In 2019 the Event Horizon Telescope international collaboration, supported by the National Science Foundation and other partners, unveiled the first image of a black hole’s event horizon, the border that defines a black hole’s ā€œpoint of no returnā€ for nearby material. NASA’s Chandra X-ray Observatory, Nuclear Spectroscopic Telescope Array (NuSTAR), Neil Gehrels Swift Observatory, and Fermi Gamma-ray Space Telescope all looked at the same black hole in a coordinated effort, and researchers are still analyzing the results.

image

6. Relativistic Jets

This Spitzer image shows the galaxy Messier 87 (M87) in infrared light, which has a supermassive black hole at its center. Around the black hole is a disk of extremely hot gas, as well as two jets of material shooting out in opposite directions. One of the jets, visible on the right of the image, is pointing almost exactly toward Earth. Its enhanced brightness is due to the emission of light from particles traveling toward the observer at near the speed of light, an effect called ā€œrelativistic beaming.ā€ By contrast, the other jet is invisible at all wavelengths because it is traveling away from the observer near the speed of light. The details of how such jets work are still mysterious, and scientists will continue studying black holes for more clues.Ā 

image

7. A Gravitational Vortex

Speaking of black holes, their gravity is so intense that they make infalling material ā€œwobbleā€ around them. Like a spoon stirring honey, where honey is the space around a black hole, the black hole’s distortion of space has a wobbling effect on material orbiting the black hole. Until recently, this was only theoretical. But in 2016, an international team of scientists using European Space Agency’s XMM-Newton and our Nuclear Spectroscopic Telescope Array (NUSTAR) announced they had observed the signature of wobbling matter for the first time. Scientists will continue studying these odd effects of black holes to further probe Einstein’s ideas firsthand.

Incidentally, this wobbling of material around a black hole is similar to how Einstein explained Mercury’s odd orbit. As the closest planet to the Sun, Mercury feels the most gravitational tug from the Sun, and so its orbit’s orientation is slowly rotating around the Sun, creating a wobble.

image

Ā 8. Gravitational Waves

Ripples through space-time called gravitational waves were hypothesized by Einstein about 100 years ago, but not actually observed until recently. In 2016, an international collaboration of astronomers working with the Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors announced a landmark discovery: This enormous experiment detected the subtle signal of gravitational waves that had been traveling for 1.3 billion years after two black holes merged in a cataclysmic event. This opened a brand new door in an area of science called multi-messenger astronomy, in which both gravitational waves and light can be studied.

For example, our telescopes collaborated to measure light from two neutron stars merging after LIGO detected gravitational wave signals from the event, as announced in 2017. Given that gravitational waves from this event were detected mere 1.7 seconds before gamma rays from the merger, after both traveled 140 million light-years, scientists concluded Einstein was right about something else: gravitational waves and light waves travel at the same speed.

image

9. The Sun Delaying Radio Signals

Planetary exploration spacecraft have also shown Einstein to be right about general relativity. Because spacecraft communicate with Earth using light, in the form of radio waves, they present great opportunities to see whether the gravity of a massive object like the Sun changes light’s path. Ā 

In 1970, our Jet Propulsion Laboratory announced that Mariner VI and VII, which completed flybys of Mars in 1969, had conducted experiments using radio signals — and also agreed with Einstein. Using NASA’s Deep Space Network (DSN), the two Mariners took several hundred radio measurements for this purpose. Researchers measured the time it took for radio signals to travel from the DSN dish in Goldstone, California, to the spacecraft and back. As Einstein would have predicted, there was a delay in the total roundtrip time because of the Sun’s gravity. For Mariner VI, the maximum delay was 204 microseconds, which, while far less than a single second, aligned almost exactly with what Einstein’s theory would anticipate.

In 1979, the Viking landers performed an even more accurate experiment along these lines. Then, in 2003 a group of scientists used NASA’s Cassini Spacecraft to repeat these kinds of radio science experiments with 50 times greater precision than Viking. It’s clear that Einstein’s theory has held up!Ā 

image

10. Proof from Orbiting Earth

In 2004, we launched a spacecraft called Gravity Probe B specifically designed to watch Einstein’s theory play out in the orbit of Earth. The theory goes that Earth, a rotating body, should be pulling the fabric of space-time around it as it spins, in addition to distorting light with its gravity.

The spacecraft had four gyroscopes and pointed at the star IM Pegasi while orbiting Earth over the poles. In this experiment, if Einstein had been wrong, these gyroscopes would have always pointed in the same direction. But in 2011, scientists announced they had observed tiny changes in the gyroscopes’ directions as a consequence of Earth, because of its gravity, dragging space-time around it.

10 Things Einstein Got Right

BONUS: Your GPS! Speaking of time delays, the GPS (global positioning system) on your phone or in your car relies on Einstein’s theories for accuracy. In order to know where you are, you need a receiver – like your phone, a ground station and a network of satellites orbiting Earth to send and receive signals. But according to general relativity, because of Earth’s gravity curving spacetime, satellites experience time moving slightly faster than on Earth. At the same time, special relativity would say time moves slower for objects that move much faster than others.

When scientists worked out the net effect of these forces, they found that the satellites’ clocks would always be a tiny bit ahead of clocks on Earth. While the difference per day is a matter of millionths of a second, that change really adds up. If GPS didn’t have relativity built into its technology, your phone would guide you miles out of your way!

Travel at the speed of light (almost).

Three Ways to Travel at (Nearly) the Speed of Light

image

One hundred years ago, Einstein’s theory of general relativity was supported by the results of a solar eclipse experiment. Even before that, Einstein had developed the theory of special relativity — a way of understanding how light travels through space.

Particles of light — photons — travel through a vacuum at a constant pace of more than 670 million miles per hour.

image

All across space, from black holes to our near-Earth environment, particles are being accelerated to incredible speeds — some even reaching 99.9% the speed of light! By studying these super fast particles, we can learn more about our galactic neighborhood.Ā 

Here are three ways particles can accelerate:

1) Electromagnetic Fields!

Electromagnetic fields are the same forces that keep magnets on your fridge! The two components — electric and magnetic fields — work together to whisk particles at super fast speeds throughout the universe. In the right conditions, electromagnetic fields can accelerate particles at near-light-speed.

image

We can harness electric fields to accelerate particles to similar speeds on Earth! Particle accelerators, like the Large Hadron Collider and Fermilab, use pulsed electromagnetic fields to smash together particles and produce collisions with immense amounts of energy. These experiments help scientists understand the Big Bang and how it shaped the universe!

2) Magnetic Explosions!

image

Magnetic fields are everywhere in space, encircling Earth and spanning the solar system. When these magnetic fields run into each other, they can become tangled. When the tension between the crossed lines becomes too great, the lines explosively snap and realign in a process known as magnetic reconnection. Scientists suspect this is one way that particles — for example, the solar wind, which is the constant stream of charged particles from the Sun — are sped up to super fast speeds.

image

When magnetic reconnection occurs on the side of Earth facing away from the Sun, the particles can be hurled into Earth’s upper atmosphere where they spark the auroras.

3) Wave-Particle Interactions!

image

Particles can be accelerated by interactions with electromagnetic waves, called wave-particle interactions. When electromagnetic waves collide, their fields can become compressed. Charged particles bounce back and forth between the waves, like a ball bouncing between two merging walls. These types of interactions are constantly occurring in near-Earth space and are responsible for damaging electronics on spacecraft and satellites in space.

image

Wave-particle interactions might also be responsible for accelerating some cosmic rays from outside our solar system. After a supernova explosion, a hot, dense shell of compressed gas called a blast wave is ejected away from the stellar core. Wave-particle interactions in these bubbles can launch high-energy cosmic rays at 99.6% the speed of light.

Young Star Cluster Trumpler 14 from Hubble Image Credit: NASA, ESA, and J. Maƭz ApellƔniz (IoAoA Spain); Acknowledgment: N. Smith (U. Arizona)

Explanation: Why does star cluster Trumpler 14 have so many bright stars? Because it is so young. Many cluster stars have formed only in the past 5 million years and are so hot they emit detectable X-rays. In older star clusters, most stars this young have already died – typically exploding in a supernova – leaving behind stars that are fainter and redder. Trumpler 14 spans about 40 light years and lies about 9,000 light years away on the edge of the famous Carina Nebula. A discerning eye can spot two unusual objects in this detailed 2006 image of Trumpler 14 by the Hubble Space Telescope. First, a dark cloud just left of center may be a planetary system trying to form before being destroyed by the energetic winds of Trumpler 14’s massive stars. Second is the arc at the bottom left, which one hypothesis holds is the supersonic shock wave of a fast star ejected 100,000 years ago from a completely different star cluster.

6 Ways NASA Technology Makes You Healthier

An important part of our mission is keeping astronauts strong and healthy during stays in space, but did you know that our technology also helps keep you healthy? And the origins of these space innovations aren’t always what you’d expect.

As we release the latest edition of NASA Spinoff, our yearly publication that celebrates all the ways NASA technology benefits us here on Earth, let’s look at some ways NASA is improving wellness for astronauts—and everyone else.

1.Ā Ā Ā Ā Ā  Weightless weight-lifting

image

Without gravity to work against, astronauts lose bone and muscle mass in space. To fight it, they work out regularly. But to get them a good burn, we had to get creative. After all, pumping iron doesn’t do much good when the weights float.

The solution? Elastic resistance. Inventor Paul Francis was already working on a portable home gym that relied on spiral-shaped springs made of an elastic material. He thought the same idea would work on the space station and after additional development and extensive testing, we agreed.

Our Interim Resistive Exercise Device launched in 2000 to help keep astronauts fit. And Francis’ original plan took off too. The technology perfected for NASA is at the heart of the Bowflex Revolution as well as a new line of handheld devices called OYO DoubleFlex, both of which enable an intensive—and extensive—workout, right at home.

2.Ā Ā Ā Ā Ā  Polymer coating keeps hearts beating

image

A key ingredient in a lifesaving treatment for many patients with congestive heart failure is made from a material a NASA researcher stumbled upon while working on a supersonic jet in the 1990s.

Today, a special kind of pacemaker that helps synchronize the left and right sides of the heart utilizes the unique substance known as LaRC-SI. The strong material can be cast extremely thin, which makes it easier to insert in the tightly twisted veins of the heart, and because it insulates so well, the pacemaker’s electric pulses go exactly where they should.

Since it was approved by the FDA in 2009, the device has been implanted hundreds of thousands of times.

Ā 3.Ā  Sutures strong enough for interplanetary transport

image

Many people mistakenly think we created Teflon. Not true: DuPont invented the unique polymer in 1938. But an innovative new way to use the material was developed to help us transport samples back from Mars and now aids in stitching up surgery patients.

Our scientists would love to get pristine Martian samples into our labs for more advanced testing. One complicating factor? The red dust makes it hard to get a clean seal on the sample container. That means the sample could get contaminated on its way back to Earth.

The team building the cannister had an idea, but they needed a material with very specific properties to make it work. They decided to use Polytetrafluoroethylene (that’s the scientific name for Teflon), which works really well in space.

The material we commonly recognize as Teflon starts as a powder, and to transform it into a nonstick coating, the powder gets processed a certain way. But process it differently, and you can get all kinds of different results.

For our Mars sample return cannister prototype, the powder was compressed at high pressures into a block, which was then forced through an extruder. (Imagine pressing playdough through a mold). It had never been done before, but the end result was durable, flexible and extremely thin: exactly what we needed.

And since the material can be implanted safely in the human body—it was also perfect as super strong sutures for after surgery.

4.Ā Ā Ā Ā Ā  Plant pots that clean the air

image

It may surprise you, but the most polluted air you breathe is likely the air inside your home and office. That’s especially true these days with energy-efficient insulation: the hot air gets sealed in, but so do any toxins coming off the paint, furniture, cooking gas, etc.

This was a problem NASA began worrying about decades ago, when we started planning for long duration space missions. After all, there’s no environment more insulated than a spaceship flying through the vacuum of space.

On Earth, plants are a big part of the ā€œlife supportā€ system cleaning our air, so we wondered if they could do the same indoors or in space.

The results from extensive research surprised us: we learned the most important air scrubbing happens not through a plant’s leaves, but around its roots. And now you can get the cleanest air out of your houseplants by using a special plant pot, available online, developed with that finding in mind: it maximizes air flow through the soil, multiplying the plant’s ability to clean your air.

5.Ā Ā Ā Ā Ā  Gas sensor detects pollution from overhead

image

Although this next innovation wasn’t created with pollution in mind, it’s now helping keep an eye on one of the biggest greenhouse gasses: methane.

We created this tiny methane ā€œsnifferā€ to help us look for signs of life on Mars. On Earth, the biggest source of methane is actually bacteria, so when one of our telescopes on the ground caught a glimpse of the gas on Mars, we knew we needed to take a closer look.

We sent this new, extremely sensitive sensor on the Curiosity Rover, but we knew it could also be put to good use here on our home planet. Ā We adapted it, and today it gets mounted on drones and cars to quickly and accurately detect gas leaks and methane emissions from pipelines, oil wells and more.

The sensor can also be used to better study emissions from swamps and other natural sources, to better understand and perhaps mitigate their effects on climate change.

6.Ā Ā Ā Ā Ā  DNA ā€œpaintā€ highlights cellular damage

image

There’s been a lot of news lately about DNA editing: can genes be changed safely to make people healthier? Should they be?

As scientists and ethicists tackle these big questions, they need to be sure they know exactly what’s changing in the genome when they use the editing tools that already exist.

Well, thanks to a tool NASA helped create, we can actually highlight any abnormalities in the genetic code with special fluorescent ā€œpaint.ā€

But that’s not all the ā€œpaintā€ can do. We actually created it to better understand any genetic damage our astronauts incurred during their time in space, where radiation levels are far higher than on Earth. Down here, it could help do the same. For example, it can help doctors select the right cancer treatment by identifying the exact mutation in cancer cells.

You can learn more about all these innovations, and dozens more, in the 2019 edition of NASA Spinoff. Read it online or request a limited quantity print copy and we’ll mail it to you!

yes: next question

no: ADHD Brain lying to me about the steps again, dangit. first task is ā€˜gather the materials’.

6) why am i having a hard time switching from my current task to this new task?

i’m having fun doing what i’m doing: it’s okay to have fun doing a thing! if task is time-sensitive, go to next question.

i have to finish doing what i’m doing: might be ADHD brain. can I actually finish the current task or will I get trapped in a cycle? does this task really need to be finished?

the next task will be boring/boring-er than the current task: ADHD brain. re-think the next task. what would make it exciting? what am I looking forward to?

I might not have enough time to complete the task: ADHD brain wants to finish everything it starts. (if task is time-sensitive, go to next question)

i just want to make the person who asked me to do it angry: sounds like anxiety brain trying to punish itself, because I know I’ll be miserable if someone is angry at me. why do i think I deserve punishment?

no, I seriously want to piss them off: okay, i’m being a shithead

7) have I already procrastinated so badly that I now cannot finish the task in time?

yes: ADHD brain is probably caught in a guilt-perfection cycle. since I can’t have the task done on time, i don’t even want to start.

reality check: having part of a thing done is almost always better than none of a thing done. if I can get an extension, having part of it done will help me keep from stalling out until the extension deadline. i’ll feel better if I at least try to finish it.

no, there’s still a chance to finish on time: ADHD brain thinks that I have all the time in the world, but the truth is I don’t.Ā 

reality check: if i’m having fun doing what I’m doing, I can keep doing it, but I should probably set a timer & ask someone to check on me to make sure I start doing the task later today.

8) I’ve completed the checklist and still don’t know what’s wrong!

probably wasn’t honest enough with myself. take one more look.

if I’m still mystified, ask a friend to help me talk it out.

hope this helps some of you! YOU’RE DOING GREAT SWEETIE DON’T GIVE UP ON YOU
