New, detailed pictures of planets, moons, and comets are neither photos nor animations — they’re made using data from 50 years of NASA mis...
On January 21, the American Museum of Natural History debuts a new planetarium show that displays the solar system with stunning accuracy.
Astronomers think the planet, called Proxima c, is a super-Earth that formed far from the icy region where scientists think such worlds are born.
NASA’s planet-hunting telescope found an Earth-size exoplanet 100 light-years away. It could hide a vast ocean.
The planet, called TOI 700 d, orbits in the habitable zone of a red dwarf star. Two telescopes confirmed its existence.
NASA has big plans for the 2020s, from powerful new space telescopes to a hunt for alien life on a moon of Saturn. Here’s the timeline.
One year ago, NASA announced it would send astronauts back to the moon. Since then, new spacecraft and telescopes have filled its plans for the 2020s.
An incredible animation by a planetary scientist shows how fast each planet spins by putting them in one giant globe
Jupiter's Great Red Spot zips around 2.4 times faster than Earth, while Venus spins so slowly you can't tell it's moving backwards.
Astronomers found 6 unusual new planets, including 3 super-Earths, by watching them vaporize and bleed gas into space
The new method aims to find planets that orbit so close to their stars that they vaporize from the heat, leaving gas behind.
Because their hydrogen-helium atmospheres balloon out, these planets are nearly as big as Jupiter, but are 100 times less massive.
A brand-new space telescope just launched into orbit. It will take an unprecedented look at alien planets circling distant stars.
The CHEOPS space telescope will attempt to study the atmospheres and composition of exoplanets. It launched Wednesday morning. following a delay.
A stunning animation by a planetary scientist shows how huge our solar system is — and why that makes it so hard to depict
The planets are so far apart, and the sun is so big, that you wouldn't be able to see anything in an accurate model of the solar system.
There is no permanent dark side of the moon, and this simple animation by a former NASA scientist explains why
The far side of the moon and the dark side are not the same thing. This animation shows how one is constantly moving, while the other never changes.
