Using the James Webb Space Telescope (JWST), astronomers have performed infrared observations of a planetary debris disk around a nearby white dwarf known as GD 362. Results of the new observations, presented October 8 on ...
Did life really exist on Mars after all? Unfortunately, there is no conclusive evidence for this yet. Nevertheless, it would seem that some form of life was the driving force behind the mysterious Martian dune gullies. Earth ...

For millions of years, a fragment of ice and dust drifted between the stars—like a sealed bottle cast into the cosmic ocean. This summer, that bottle finally washed ashore in our solar system and was designated 3I/ATLAS, ...

A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The researchers found that the proposed mechanism would actually produce the opposite effect, given the ...
In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants of dead stars.
Astronomers have identified an enormous "growth spurt" in a so-called rogue planet. Unlike the planets in our solar system, these objects do not orbit stars, free-floating on their own instead. The new observations, made ...
