Brain scans capture memory formation in babies, raising new questions about why people forget their earliest years

Earlier this year, astronomers reported possible evidence of life on another planet – but new observations from JWST suggest the apparent biosignature isn’t there after all

Set your alarm on Wednesday to see some of the summer’s stunning meteor showers.

Ultimately, we do not understand where glitches come from or exactly what's going on inside pulsars.

Nebulas are perhaps as famous for being identified

The cast of "Star Trek: Strange New Worlds" has to cover a wide range of dramatic genres, aided in part by the show's ample stockpile of wigs.

A new behind-the-scenes featurette from Hulu's upcoming 'Alien: Earth' show why the series will be pure nightmare fuel.

The European company Eos X Space has acquired Space Perspective, one of its key rivals in the nascent field of stratospheric balloon tourism.

Satellite data allows meteorologists to keep track of the location, structure and intensity of severe weather, helping to keep people safe. Now they're losing access to these satellites.

Mars will be less than four degrees from the crescent moon around sunset on July 28.

After an early morning launch from Florida, SpaceX sent another 24 Starlink satellites into orbit on a Falcon 9 launch from Vandenberg Space Force Base in California early on Sunday, July 27, 2025.

After 20 years of observations, Georgia State University's CHARA (Center for High Angular Resolution Astronomy) has proven its worth. In 2005, The Astrophysical Journal published the first results based on its observations. Since then, more than 275 papers based on CHARA observations have been published, and the facility is still going strong heading into its third decade of operations.

Researchers working with China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) have revealed some of the complexity in a type of cloud in the ISM. They've detected a network of filaments in one Very High Velocity Cloud (VHVC). The observations hint at the complexity that can evolve in these clouds, all without the influence of gravity.

To explore the unknown in deep space, millions of miles away from Earth, it’s crucial for spacecraft to have ample power. NASA’s radioisotope power systems (RPS) that rely on are a viable option for these missions and have been used for over 60 years. Now, NASA is testing a new type of RPS fuel that could become an additional option for future long-duration journeys to extreme environments.

The NASA, JAXA and Roscosmos crew members set to launch next to the International Space Station arrived at Kennedy Space Center in Florida on Saturday, July 26, 2025.

On Episode 170 of This Week In Space, Rod Pyle and Tariq Malik are joined by Dr. Robert O'Brien to discuss powering spacecraft by radioisotope thermoelectric generators (RTGs).
