Watch the Artemis moon rocket’s final prelaunch test

The fourth attempt of a final prelaunch test started on Saturday, with fueling of the rocket expected to begin Monday morning. The crucial test, known as the wet dress rehearsal, simulates every stage of launch without the rocket leaving the launchpad at Kennedy Space Center in Florida. This process includes loading supercold propellant, going through … Read more

Greenland polar bear population lives without sea ice

Scientists who studied and tracked the bears determined that they survive despite having limited access to sea ice — something that is critical for polar bears — and instead use the freshwater ice supplied by Greenland’s ice sheet. “We wanted to survey this region because we didn’t know much about the polar bears in Southeast … Read more

Black hole wandering Milky Way galaxy spied by Hubble

When stars massive enough to dwarf our sun die, they explode in a supernova and the remaining core is crushed by its own gravity, forming a black hole. Sometimes the explosion may send the black hole into motion, hurtling across the galaxy like a pinball. By rights, there should be a lot of roving black … Read more

June’s full moon, the strawberry moon, will peak on Tuesday

The moon will appear full from Sunday moonrise to Wednesday moonset, according to NASA. It will reach its peak at 7:52 am ET Tuesday but will not be fully visible in North America until moonrise.

Mastodon tusk reveals North America migration patterns

The mastodon’s fossil was first found on a farm in 1998 by Kent and Janne Buesching, who were mining for peat on their property. Archaeologists then excavated the Buesching mastodon’s remains. His skeleton, which is 9 feet (2.7 meters) tall and 25 feet (7.6 meters) long, has been studied since 2006. A closer look at … Read more

Strange tsunami-like quakes shake some of the stars in our galaxy, Gaia spacecraft reveals

The unusual starquakes are among multiple new discoveries made by Gaia, a mission launched in 2013 to create the “most accurate and complete multi-dimensional map of the Milky Way.” On Monday, ESA released its third batch of data from the spacecraft, revealing fresh details on nearly 2 billion stars in our galaxy. “Starquakes teach us … Read more

Repeating fast radio bursts from space are mysterious. This one is even weirder

We’re driven to determine if “the truth is out there.” If we just had all of the pieces, they might fit together and form the bridge to a greater understanding. The team will gather evidence and analyze data for unexplained events in the sky from a scientific perspective to determine if they are natural or … Read more
