NASA astronaut Jeanette Epps, who was slated to be the first African-American spacefarer to serve as a long-term crew member on the International Space Station until she was pulled from the roster in January, is still waiting on an explanation of why.

SpaceX Wins $130 Million Falcon Heavy Contract to Launch Classified USAF Satellite in 2020 SpaceX Wins $130 Million Falcon Heavy Contract to Launch Classified USAF Satellite in 2020

SpaceX, the Elon Musk-helmed company which earlier this year saw its partially reusable Falcon Heavy officially become the most powerful rocket in the world, has won its first contract to use that system to deliver a classified payload.

Einstein's Theory of Gravity Passes Enormous Test on a Galaxy Einstein's Theory of Gravity Passes Enormous Test on a Galaxy

It would be hard to overstate how resilient the theory of general relativity has been. In its hundred-plus-year history, it’s managed to predict things far beyond the capabilities of 1910s experiments, and it withstands every new test scientists throw at it.

The Trailer for The Man Who Unlocked the Universe Is a Gorgeous Mixture of Science and Action The Trailer for The Man Who Unlocked the Universe Is a Gorgeous Mixture of Science and Action

There’s a new docudrama coming out tomorrow about the life of Ulugh Beg, an obscure medieval astronomer who made Samarkand, now Uzbekistan, a thriving center of culture and science in the 15th century.

America Isn't Ready to Handle a Catastrophic Asteroid Impact, New Report Warns America Isn't Ready to Handle a Catastrophic Asteroid Impact, New Report Warns

We’ve long said that humans generally worry about the wrong asteroids. Tabloids love to publish headlines about “potentially hazardous asteroids,” a category created by NASA that can be a bit misleading. The truly worrisome rocks are the smaller ones that we aren’t tracking.

Scientists Find Stronger Evidence for New Kind of Black Hole Scientists Find Stronger Evidence for New Kind of Black Hole

We’ve seen supermassive black holes at the centers of galaxies tearing stars to shreds. We’ve detected the energy wave from relatively tiny black holes slamming together to create a wobble in space-time a billion light-years away. But what about the medium-sized black holes in between these extremes?

This Video Made From Real Mars Data Will Make You Feel Like You're Flying Over the Red Planet

There are lots of incredible things you can do with data. Like make this incredible animation of the Martian surface, for example.

Black Holes Can Maybe Turn Into Dark Matter Lasers Black Holes Can Maybe Turn Into Dark Matter Lasers

Black holes are already some of the strangest objects in the universe, and scientists sometimes dream up some pretty wild theories about their behavior. Like maybe they can accumulate dark matter particles and turn into black hole lasers, beaming radiation out into space.

Detection of Diamond Dust Around Distant Stars Solves Decades-Long Mystery Detection of Diamond Dust Around Distant Stars Solves Decades-Long Mystery

For years, astronomers have struggled to understand the source of anomalous microwave emissions coming from various locations across the Milky Way galaxy. A recently concluded survey of the planet-forming disks around young stars suggests these strange transmissions are being produced by something rather…

NASA's New Horizons Is Awake and Ready to Explore Space Beyond Pluto NASA's New Horizons Is Awake and Ready to Explore Space Beyond Pluto

Pluto’s most famous visitor, the New Horizons spacecraft, has woken up after 165 days of hibernation.

Curiosity Rover Finds 3.5-Billion-Year-Old Organic Compounds and Strange Methane on Mars Curiosity Rover Finds 3.5-Billion-Year-Old Organic Compounds and Strange Methane on Mars

No, NASA hasn’t discovered life on Mars yet—but a new result makes it seem like maybe, at some point in the planet’s history, the conditions were ripe for some extraterrestrial beings. Maybe.

What Is Dark Matter and Why Hasn't Anyone Found It Yet?

Five-sixths of the universe’s stuff seems to be missing, and we just can’t find it. It’s called “dark matter,” and scientists have gone looking for it with some of the world’s largest, most expensive experiments.

Jupiter's Lightning Is Somehow More and Less Like Earth's Than Scientists Thought Jupiter's Lightning Is Somehow More and Less Like Earth's Than Scientists Thought

As unearthly as it may be, Jupiter shares a phenomenon with our own planet that you might find very familiar: lightning strikes. And lightning on Jupiter is somehow both more (and less) like the lightning on Earth than scientists previously thought.

NASA to Extend Juno Jupiter Mission by Three Years NASA to Extend Juno Jupiter Mission by Three Years

The Juno spacecraft currently orbiting Jupiter was supposed end its mission by crashing into the gas giant next month. Not anymore!

NASA's Administrator Is Talking to Private Companies About Commercial Takeover of the ISS NASA's Administrator Is Talking to Private Companies About Commercial Takeover of the ISS

You may have heard about the White House’s plans to privatize the International Space Station and turn low-Earth orbit into a place of business that NASA can become a customer of, rather than its sponsor. Now, according to an interview with the Washington Post, NASA’s recently confirmed Jim Bridenstine has begun…

Small Asteroid Strikes Africa Just Hours After It Was Spotted Small Asteroid Strikes Africa Just Hours After It Was Spotted

A meteor lit up the sky over Botswana, Africa, early Saturday evening. Scientists discovered the six-foot-wide asteroid just hours before it reached Earth.

Astronomers Spot Surprising Evidence of Methane Dunes on Pluto Astronomers Spot Surprising Evidence of Methane Dunes on Pluto

Astronomers peering closely at images of Pluto have spotted what look like dunes on the surface of the former planet. They wouldn’t be sand dunes, but dunes of methane ice—an Earthly feature on a totally alien world.

Experiment Could Help Scientists Predict Avalanches Through Sound Experiment Could Help Scientists Predict Avalanches Through Sound

It turns out that 8,000 tiny plastic disks in a rotating drum could help scientists develop a technique to forecast avalanches or earthquakes through sound.

Jeff Bezos Details Plan to Make Blue Origin the Amazon of the Moon Jeff Bezos Details Plan to Make Blue Origin the Amazon of the Moon

Amazon CEO Jeff Bezos’ plans to splurge some of his jaw-dropping wealth pushing his private spaceflight company Blue Origin towards the business of moon colonization—think Elon Musk’s dreams of a SpaceX-backed colony on Mars, but much less likely to get everyone involved killed—dropped last year.

NASA's New Exoplanet Hunter Releases Incredible First Image NASA's New Exoplanet Hunter Releases Incredible First Image

On the way to its final orbit around Earth, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) has sailed by the moon and snapped its first picture of space. We’ve said several times that TESS would be able to look at 200,000 stars in the 300 light-years around the Earth—but maybe this new shot will…
