In globular clusters you will find a lot of older, redder stars packed closely together. In many ways, they’re the retirement homes for the galaxy.
The comet's frequent recurrence has played a part in historical events for millennia.

SpaceX launched 105 small satellites from Cape Canaveral on the company’s third Transporter rideshare mission Thursday, deploying payloads for commercial remote sensing companies, communications and data relay startups, and foreign governments.
The study of extrasolar planets has revealed some interesting things in recent decades. Not only have astronomers discovered entirely new types of planets – Super Jupiters, Hot Jupiters, Super-Earths, Mini-Neptunes, etc. – it has also revealed new things about solar system architecture and planetary dynamics. For example, astronomers have seen multiple systems of planets where the orbits of the planets did not conform to our Solar System.
China's Shenzhou 13 astronauts conducted a manual rendezvous and docking test over the weekend to test emergency procedures for spacecraft visiting the Chinese space station.
Organic molecules found in a Mars meteorite that crash-landed on Earth are not signs of life, but instead formed in chemical reactions between water and rock on the Red Planet about 4 billion years ago.
A group of physicists has measured gravity using the effects of time dilation — the slowing of time imparted by increased velocity or gravitational force — on atoms.
Saturn’s icy moon Enceladus harbors a subsurface ocean, and many astronomers have believed that watery plumes erupting from its surface might provide an easy way to sample it. But computer […]
Live coverage of the countdown and launch of a Virgin Orbit LauncherOne rocket. The air-launched rocket will climb into orbit with seven small satellites after release from a Boeing 747 carrier aircraft southwest of Los Angeles. Text updates will appear automatically below. Follow us on Twitter.
For over 60 years, dedicated teams in NASA's Mission Control have provided support for astronauts in space. Out of the thousands on staff during that time, less than 100 led the room, until now.
Time for another tantalizing glimpse of what alien solar systems might look like.
SpaceX successfully launched 105 small satellites into orbit before landing a veteran booster back on Earth on Thursday (Jan. 13).
Saddle up, Spartans! Our list of Halo games in chronological order takes you on a journey of the legendary franchise.

The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe.
What fills the vast spaces between the stars? Mostly nothing – those expanses would register as a vacuum in a laboratory here on Earth. But it’s not completely, totally, 100% empty. If you look closely, and wait long enough, you’ll see a beehive of activity.
The highly anticipated Europa Clipper mission, set to launch in 2024, will investigate Jupiter’s moon Europa. This icy moon with a subsurface ocean is considered one of the most enticing places in our Solar System where life might exist. To look beneath Europa’s icy crust, the Clipper mission has a host of instruments looking for plumes and ‘hot spots.’
Stellar groupings orbiting the outskirts of the Milky Way shed new light on the elusive dark matter surrounding our galaxy.
The "Above the Clouds" mission is scheduled to lift off from California's Mojave Air and Space Port today (Jan. 13) between 4 p.m. and 6:30 p.m. EST (2100 to 2330 GMT).
SpaceX is preparing another one of its Falcon 9 rockets to launch a bevy of small satellites into space this morning (Jan. 13), and you can watch the fiery action live online.
A rare type of white dwarf star has been erupting in the most extreme superflares of its kind ever seen, researchers find in a new study.
