Here's a quick guide to tell meteors from machines in your wide-field images of the night sky.
I have spent a fair amount of time thinking about what happens to the human body and mind under extreme conditions. But here is something I had not fully considered… when astronauts arrive in space after a lifetime on Earth, their brains still think gravity is there. And that turns out to matter rather a lot.
"We really think it's our best season yet."
Scientists have identified at least seven carbon-rich molecules that NASA's Curiosity rover detected on Mars, and they're more complex than any found before.
On top of Kitt Peak in the Arizona Desert, a robotic surveyor just completed a five year mission to catalogue the positions of tens of millions of galaxies. The Dark Energy Spectroscopic Instrument (DESI) has now created the largest, most detailed 3D map of our universe ever constructed. And it’s not done yet, its main mission has been extended through 2028.
The Sombrero galaxy's name fits perfectly.
Earth's moon is to be on the receiving end of a spent rocket stage in early August - the leftovers from a SpaceX Falcon 9 launch last year.
A new citizen science project invites the public to scan never-before-seen images from the Euclid Space Telescope in search of galaxies bending spacetime.
To mark the first anniversary of the European Space Agency’s Biomass satellite, we present a selection of striking images captured over the past 12 months, revealing Earth’s forests, and much more, in new detail. In just one year, this pioneering mission has begun transforming our understanding of forest dynamics and advancing how scientists monitor the critical role forests play in regulating the global carbon cycle.
A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed prior to the dawn of time.
New simulations suggest binary star systems may be ideal for planet formation, and may produce more gas giants than single-star systems.
Exoplanet science and the search for life beyond Earth continue to advance at break-neck speeds, with the number of confirmed exoplanets by NASA rapidly approaching 6,300, with 223 of those exoplanets being designated as terrestrial (rocky) exoplanets. With the promise of discovering an increasing number of Earth-sized exoplanets increasing every day, new telescopes from across the world have the opportunity to contribute to this incredible field.
You’re in the lab analyzing Martian regolith samples within your cozy Mars habitat serving on fifth human mission to Mars. The power within the habitat has been flowing flawlessly thanks to the MARS-MES (Mars Atmospheric Resource & Multimodal Energy System), including the general habitat lighting, science lab, sleeping quarters, exercise equipment, the virtual reality headsets the crew use for rest & relaxation, oxygen and fuel generation, and water. All this from converting the Martian atmosphere into workable electricity.
Imagine a mountain range many times larger than the entire Earth, floating in mid-air, held up by nothing you can see. It sounds like something from a fantasy novel but that is essentially what solar prominences are and for decades, scientists have struggled to explain how they exist at all.
If you have ever pushed your finger against the hole of a bicycle pump and felt the air grow warm as you compressed it, you already understand the physics at the heart of a new discovery about our own Galaxy. Because it turns out the Milky Way has a hot side and a cool side and the reason why comes down to exactly the same principle.

SpaceX will try again Wednesday to launch its Falcon Heavy rocket from NASA’s Kennedy Space Center, following a last-minute scrub Monday due to poor weather.
Astronomers have found the boundary of star formation in the Milky Way's spiral disk — and it's not as far out from the center of our galaxy as you might imagine.
The universe is composed of 92 naturally occurring elements, yet a few dominate the cosmos. The overwhelming majority of the universe's ordinary matter is made up of just two elements: Hydrogen and Helium.
Should Pluto be a bona fide planet again? NASA is working to "revisit the discussion" on Pluto's planethood status, according to agency chief Jared Isaacman.
When we build things on wonder, it naturally opens the mind.
