Europe's Mars sample return orbiter moving ahead despite NASA budget uncertainty
The European Space Agency's Earth Return Orbiter has passed its design review, which validates its technical details and moves the project onto manufacturing and testing.
The early solar system was donut-shaped, meteorite study suggests
Researchers studying iron meteorites suggest that the early solar system took the shape of a donut, not a dartboard as previously thought.
Once-in-a-lifetime star explosion, visible from Earth, could happen any day now
Binary star system T Coronae Borealis (T CrB) is about to go nova any day now. The recurrent nova explodes approximately every 79 or 80 years.

James Webb Space Telescope spies never-before-seen star behavior in distant nebula (video, photo)
A new James Webb Space Telescope image shows perfectly aligned protostellar outflows in the Serpens Nebula, supporting a long-running theory of stellar formation.
Is Jupiter's Great Red Spot an impostor? Giant storm may not be the original one discovered 350 years ago
Astronomer Giovanni Cassini observed Jupiter's 'Permanent Spot' in 1665, but new research suggests it's a different vortex from today's Great Red Spot.
Could nearby stars have habitable exoplanets? NASA's Chandra X-ray Observatory hopes to find out
Astronomers are using the Chandra X-ray Observatory to study stars' radiation and establish the feasibility of exoplanet habitability.
Voyager 1 is back online! NASA's most distant spacecraft returns data from all 4 instruments
Following a technical error in November 2023, NASA's deep-space explorer has resumed full science operations.
Bark! Meow! Cluck! NASA uses lasers to beam pictures of pet dogs, cats and chickens to the ISS
NASA is testing how infrared light can transfer far more information than radio frequency communications.
Mars meteorites reveal clues about what lies within the Red Planet
Volcanic meteorites from Mars give scientists a glimpse into the planet's structure.
Jupiter's raging gas cyclones may actually mirror Earth's oceans. Here's how
Jupiter and Earth's oceans have more in common than you might think.
Satellite data reveals Antarctica's Thwaites Glacier is melting faster than we thought
The ICEYE satellite constellation has given researchers a peek beneath the glacier, and it's not looking good.
Solar storm frenzy of May 2024 was strong enough to affect the deep sea
Ocean Networks Canada's (ONC) deep-sea observatories recorded disturbances in the Earth's magnetic field.
India's space agency has been carefully watching our sun's solar tantrums
The Indian Space Research Organization has released solar storm data from ground stations and spacecraft, including the Chandrayaan-2 lunar orbiter.
To better predict volcanic eruptions, you have to dig deep — very deep
New research suggests studying the state of magma in deep reservoirs can improve volcanic eruption predictions.
See this galaxy's bright center? It's home to a voracious supermassive black hole
To launch Black Hole Week, NASA released this new Hubble image of spiral galaxy NGC 4951.
A Switzerland-size hole opened in Antarctica's sea ice in 2016-17. Now we know why
During the winters of 2016 and 2017, a hole the size of Switzerland opened in the middle of Antarctica's sea ice. And scientists just figured out how it came to be.
This spacecraft is headed to NASA's asteroid-crash aftermath — but first, it'll stop by Mars
During a gravity assist with Mars, Hera will study the moon Deimos.
Private moon lander will carry Nokia's 4G cell network to the lunar surface this year
Nokia is developing a LTE/4G communications system for the moon, and its first piece of the network might launch as soon as late this year.
Watch 2 gorgeous supernova remnants evolve over 20 years (timelapse video)
These supernova remnants are moving at extraordinary speeds only visible to us in long-term timelapses.
Mars' subsurface is 'burping' out methane and scientists aren't sure why
A new theory suggests that NASA's Curiosity rover could be "burping" the surface of the Red Planet, releasing methane trapped beneath a salty crust.
When is the next total solar eclipse in the US?
The next total solar eclipse to hit the United States will be in 2033, but it will only be visible in Alaska. The Lower 48 won't get one until 2044.
