An artist's conception of the dust and gas surrounding a newly formed planetary system.

Earth is screaming through space at 1.3 million mph. A simple animation by a former NASA scientist shows what that looks like.

Earth orbits the sun, which orbits the center of the Milky Way galaxy, which is itself barreling through space.
Saturn's largest moon, Titan, passes the planet undergoing seasonal changes in this natural color view from NASA's Cassini spacecraft.

20 new moons were just discovered orbiting Saturn, and you can help name them

Saturn now has more moons than any other planet in our solar system. You can suggest names for 20 newly discovered moons in a Twitter contest.
Patrick Stewart plays Jean-Luc Picard in the sci-fi space series "Star Trek."

Warp speeds in ‘Star Trek’ are achingly slow, and a simple animation by a former NASA scientist proves it

The animation shows how long it takes the starship Enterprise in "Star Trek" to reach Pluto at warp factors that break the known laws of physics.
A photograph of Enceladus, an icy moon of Saturn, taken by NASA's Cassini probe.

The ocean on Saturn’s moon Enceladus contains the building blocks of life, NASA data reveals

NASA data revealed the most basic ingredients of life in bursts from an ocean on Saturn's moon Enceladus.
This artist's concept shows NASA's InSight lander with its instruments deployed on the Martian surface. The seismometer is the round device to the left of the lander.

NASA’s InSight lander on Mars has detected more than 20 quakes. Early data suggests the red planet may be less Earth-like than we thought.

NASA's InSight lander has heard lots of rumbling on Mars. A seismologist says the quakes are changing our understanding of the planet's crust.
In this handout provided by the National Aeronautics and Space Administration, a satellite image shows the far side of the moon as it crosses between the DSCOVR spacecraft and the Earth, at one million miles away.

The moon has been drifting away from Earth for 4.5 billion years. A stunning animation shows how far it has gone.

The video shows how the moon reached its current position after starting as an orb of molten rock and magma hovering just above Earth.
This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole’s event horizon, where no light can escape the massive object’s gravitational grip.

Planet 9, our solar system’s mysterious missing world, could be an ancient black hole orbiting the sun, a new paper suggests

A primordial black hole from the birth of the universe could be lurking at the edge of our solar system.

An amateur astronomer accidentally recorded a rare flash on Jupiter. The culprit turned out to be a 450-ton meteor.

The asteroid's impact released as much energy as the explosion of 240,000 tons of TNT, according to new analysis of the video.
Gemini Observatory's two-color composite image of C/2019 Q4 (Borisov), which is likely the first interstellar comet ever identified. Blue and red dashes are background stars that appear to streak as the comet moves.

A new image of a mysterious object careening toward our solar system strongly suggests it’s the first comet from another star system

C/2019 Q4 is likely the first comet ever detected that came from another star system. Our clearest image of it shows its dust cloud and gas tail.
An artist's concept of a lake at the north pole of Saturn's moon Titan. The raised rims and rampart-like features reflect the observations made by NASA's Cassini spacecraft.

Lakes of methane on Saturn’s moon Titan may be the craters of giant explosions, a new study shows

NASA's Cassini probe at Saturn revealed lakes with steep rims on Titan. They could be craters created by exploding nitrogen.
