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, 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.
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.
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.
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.
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?
There are lots of incredible things you can do with data. Like make this incredible animation of the Martian surface, for example.
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.
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…
Pluto’s most famous visitor, the New Horizons spacecraft, has woken up after 165 days of hibernation.
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.
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.
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.
The Juno spacecraft currently orbiting Jupiter was supposed end its mission by crashing into the gas giant next month. Not anymore!
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…
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 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.
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.
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.
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…
