Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

Every week, it feels like something new pops up in space news. Lately, astronomy news today has been all over the place—from wild discoveries about the Sun to weird planets and black holes that break ...

This year's Harvest Moon will be a special treat for space fans since it will also be the first supermoon of the year.

While it’s hard to see the solar wind directly in photos once it leaves the corona, we can measure the gas directly with instruments in space. Scientists have recently gotten up ...

First, consider that the Earth spins around like a top. It’s rotating around the imaginary line that runs from the North Pole to the South Pole through the center of our planet. Earth completes one ...

Astronomers have already discovered nearly 6,000 planets outside our solar system, but none of them are true “Earth twins.” Scientists are especially interested in finding planets that are about the ...

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and Earth. The authors dubbed it Planet Y.

Astronomers have observed a massive growth rate in a free-floating rogue planet that’s gobbling up gas and dust at a record rate of 6.6 billion tons per second.

A UCLA astronomer who leads planetary defense missions for NASA says avoiding asteroid impacts is “a problem we can absolutely solve.” ...

The ISS feels impossibly far at 250 miles up, but lunar missions go 240,000 miles out - over 1000x the distance. It's a perspective shift that redefines what 'space travel' means.

The striking thing about this is that repeating the procedure on the star turned up no evidence of carbon-based chemicals, even though the system is young enough that it should still have a ...
