SpaceX launched another batch of its Starlink internet satellites from Florida's Space Coast this evening (April 17), and landed its rocket on a ship at sea.

The 2024 solar eclipse, as seen from Indianapolis, connected strangers across a famous racetrack.

A study suggests the ice giants Uranus and Neptune aren't quite as watery as previously thought. They may also contain huge amounts of frozen methane, potentially solving the puzzle of how they formed.

The unexplained mass of a remarkably massive galaxy suggests that dark matter interacts with itself, according to new observations by the James Webb Space Telescope.

Boeing's Starliner spacecraft moved between buildings at NASA's Kennedy Space Center in Florida to get ready for launch. Its first astronaut mission is expected on May 6.

The robotic telescopes of the Virtual Telescope Project have observed a quasar powered by a supermassive black hole 3 billion times as massive as the sun at the very edge of the universe

BepiColombo spotted an outpour of carbon and oxygen atoms in Venus' fragile magnetic environment

Switzerland became the 37th country to sign the Artemis Accords for peaceful moon exploration with NASA on April 15, following the inclusion of Greece and Uruguay in February.

To see the premier astronomical observatory in its full-size glory, you need to go to Lagrange Point 2, a location farther away than anyone has traveled. Or, soon, you can visit Colorado.

The first year of Dark Energy Spectroscopic Instrument (DESI) data seems to show that dark energy is weakening over time, possibly the biggest cosmological discovery for 25 years.

A detailed analysis of the Winchcombe meteorite has found evidence that its parent asteroid was altered by water before being smashed apart multiple times.

The small object that crashed through the roof of a Florida home last month was indeed part of a pallet jettisoned from the ISS three years ago, NASA has confirmed.

NASA is asking its various research centers as well as private industry for new ideas about how to get Mars samples back to Earth relatively quickly and cost-effectively.

NASA astronaut Loral O'Hara missed watching an eclipse from the ISS by days. But she did participate in the 4th all-woman spacewalk, and has a unique story about a baby octopus.

Astronomers have measured the stellar winds of three sun-like stars for the first time, finding that the objects are losing mass at a rate as great as 67 times the speed at which our star sheds matter.

A first-of-its-kind lab demonstration shows how solar power transmission from space could work.

Some black holes are so massive they were likely created as smaller black holes that merged. Maybe we can use such black hole "children" to learn about the black hole "ancestors."
