Researchers spied a wild array of life, including dozens of suspected new species, in an underwater gorge

It's back to the Wasteland for more nuked nightmares when Prime Video's hit sci-fi series returns in December.

The 60-meter asteroid 2024 YR4 has a 4 percent chance of hitting the moon. Could such a lunar collision create a dangerous new meteor shower?

Peanut allergies more than tripled in U.S. kids between the late 1990s and late 2000s, and the prevalence has risen even more since then. Scientists are still searching for answers—and new ways to treat them.

The impending merger of the two galaxies hints at what might be in store for the Milky Way and the Andromeda galaxy if and when they collide.

The Kite of Boötes tips. The Great Square of Pegasus balances en pointe. Cassiopeia climbs. And Saturn muscles up in the east.

The camera battery died about 2am local time

The U.S. Space Force's X-37B space plane lifted off atop a SpaceX Falcon 9 rocket tonight (Aug. 21), carrying a variety of high-tech gear to Earth orbit.

Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently. In order to understand the exoplanet population, and to make progress understanding habitability, astronomers need to understand and constrain exoplanets' magnetic fields. Detecting them may best be done from the Moon.

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we’re not as familiar with. Scientists think they understand how the most important Moon in our solar system (our own) formed, but its violent birth is not the norm, and can’t explain larger moon systems like the Galilean moons around Jupiter. A new book chapter (which was also released as a pre-print paper) from Yuhito Shibaike and Yann Alibert from the University of Bern discusses the differing ideas surrounding the formation of large moon systems, especially the Galileans, and how we might someday be able to differentiate them.

The Universe's early galaxies were engulfed in halos of high-energy cosmic rays. It's likely because they had tangled and turbulent magnetic fields. These fields accelerate cosmic rays to higher energies.

SpaceX has moved its giant Super Heavy booster to the launch pad ahead of Sunday's (Aug. 24) planned liftoff of the Starship megarocket.

In his latest book, science journalist Peter Brannen argues that CO2 is the most important—and most misunderstood—molecule on Earth

A weird and extremely violent new type of supernova in which a massive star was "stripped to the bone," offers a rare glimpse of the interior of a massive star prior to its death.

An analysis of active US mines finds they already collect virtually all of the minerals the country needs for batteries, solar panels and wind turbines – but these critical minerals mostly go to waste

Dark-coloured cars can make a measurable difference on nearby air temperature, and in cities of millions the effect can add up and noticeably increase how hot it feels

Some stars in the universe grow to 300 times larger our own sun. But how do they get so big, and how do they sustain their mass?
