In 23 billion years, these two white dwarf stars will collide. Then, they'll explore. Here's why scientists say this discovery is such a big deal.

Despite their name, black holes can sometimes emit radiation. A team of astronomers has recently detected a flicker of X-ray radiation from the supermassive black hole at the center of the Andromeda Galaxy. This flicker was identified using 15 years of data from the Chandra X-ray Observatory, revealing two distinct flashes in 2006 and 2013. Interestingly, these flashes coincided with bursts of neutrinos detected by the IceCube Neutrino Observatory, offering exciting new insights into the extreme conditions surrounding the black hole.

New 'Superman' trailer gives us more Krypto, a better look at the Fortress of Solitude, and a giggling robot with a familiar voice.

Terraforming Mars has been the long-term dream of colonization enthusiasts for decades. But when you start to grapple with the actual physics of what would be necessary to do so, the effort seems further and further out of reach. Depictions like those of Kim Stanley Robinson's Mars Trilogy are just wildly unrealistic regarding the sheer amount of material that must be moved to the Red Planet to achieve anything remotely resembling Earth-like conditions. That is the conclusion of an abstract presented at the 56th Lunar and Planetary Science Conference by Leszek Czechowski of the Polish Academy of Sciences.

NASA celebrated the release of its Artemis 2 crew patch by projecting the insignia's art onto the iconic Vehicle Assembly Building (VAB) in Florida.

SpaceX's Fram2 astronauts take the first X-ray images of the human body in space, with a tip-of-the-hat to the first X-ray image ever taken.

The LIFE mission would feature four space telescopes acting together to search for biosignatures on rocky planets in the habitable zones of their stars.

A sudden stratospheric warming event reversed the winds that make up the northern polar vortex on March 9. A new animation shows the vortex also moved away from the Arctic towards Europe.

Extraordinarily powerful light from gamma-ray bursts might help produce heavy elements from the outer shells of dying stars.

The comet was first spotted by an amateur astronomer looking through SOHO spacecraft data.

A Russian Soyuz rocket will launch three astronauts toward the International Space Station early Tuesday morning (April 8), and you can watch the action live.

Jamming and spoofing attacks on space-based services have increased by greatly over the past few years, and technologists are racing to find ways to keep the onslaught at bay.

Europe’s space industry gathered at the European Space Agency (ESA) in the Netherlands on 3–4 April to gain insights into the future of space in Europe.

In 1986, the Voyager 2 spacecraft made a flyby of Uranus. It gave us the first detailed images of the distant world. What was once only seen as a featureless pale blue orb was revealed to be...well, a mostly featureless pale blue orb. The flyby gave astronomers plenty of data, but the images Voyager 2 returned were uninspiring. That's because Voyager only viewed Uranus for a moment in time. Things change slowly on the ice giant world, and to study them you need to take a longer view.

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust above it to "drip" and suck down rocks from across the continent.

Ncuti Gatwa is back with a shower of outer space action for Disney+'s sci-fi series

The Lyrid meteor shower, one of the oldest known of the annual showers, peaks this year with only some small interference from a waning crescent moon.

The interactive female astronaut series was created to inspire a new generation of space explorers.

Blue Origin is receiving some backlash ahead of its upcoming all-female spaceflight, with actress Olivia Munn criticizing the venture as "gluttonous."

The bacteria, Sporosarcina pasteurii, is able to make calcium carbonate that can act as a sealant to fix bricks made from lunar regolith.
