A snapshot of the American Natural History Museum's "Worlds Beyond Earth" immersive theater experience.

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.
An artist's rendering of the Proxima Centauri planetary system, with the potential new planet on the right and Proxima b on the left.

A second planet might orbit the closest star to the sun, and astronomers think it’s a super-Earth

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.
Exoplanet TOI 700 d is the first Earth-size world NASA's TESS space telescope has found that's in its star's habitable zone.

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.
Engineers observe the first driving test for NASA's Mars 2020 rover at the Jet Propulsion Laboratory in Pasadena, California, December 17, 2019.

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.
The band of the Milky Way stretches across the sky above the 2.2-meter telescope at the La Silla Observatory in Chile. This is where astronomers watched three stars to find vaporizing planets in their orbits.

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.
An artist's illustration of the sun-like star Kepler 51 and two of its three giant super-puff planets that NASA's Kepler space telescope discovered in 2012.

NASA has confirmed a new class of huge ‘super-puff’ planets that have the density of cotton candy

Because their hydrogen-helium atmospheres balloon out, these planets are nearly as big as Jupiter, but are 100 times less massive.
An artist's impression of CHEOPS, the ESA's Characterizing Exoplanet Satellite, in orbit above Earth.

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.
The sun absolutely dwarfs every planet.

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.
Just like the near side of the moon, the far side cycles through day and night phases.

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.
