Temperatures are rising, and so are mental health risks

As warmer waters and ocean acidification reduce coral formation, the seas will take up more carbon dioxide – an effect that hasn't been included in climate models

The U.S. Astronaut Hall of Fame just held its annual induction ceremony, but one of this year's two honorees could not attend for a reason unique to all past enshrinements.

Mars' core formed within just a few million years, scientists say compared to the hundreds of millions or even billions of years that it took for Earth's core to form — it also might smell like rotten eggs.

Scientists have discovered a star behaving like no other seen before, giving fresh clues about the origin of a new class of mysterious objects.

Microwaves can control a single quantum bit more precisely than ever before, creating a device similar to a quantum transistor – and potentially making quantum computers more reliable

As Star Citizen approaches a billion dollars in funding and with no full release date in sight, we take a look at its history and the current state of this ambitious space epic.

Aurora Australisa, or the "southern lights" was on full display on June 1, 2025, as spectators outside Christchurch, New Zealand witnessed firsthand.

Tokyo-based company ispace aims to land its "Resilience" spacecraft in the moon's Mare Frigoris ("Sea of Cold") region on June 5, notching a big milestone for Japan and for commercial spaceflight.

A collision between the Milky Way and neighboring galaxy Andromeda is far from a sure thing; in fact, it could hinge on the flip of a cosmic coin.

Neuroscientists can now make precise genetic tweaks to the neurons that are most affected by brain diseases such as Parkinson’s, Huntington’s and ALS

Over a decade’s worth of NASA/ESA Hubble Space Telescope data was used to re-examine the long-held prediction that the Milky Way galaxy will collide with the Andromeda galaxy in about 4.5 billion years. The astronomers found that, based on the latest observational data from Hubble and Gaia, there is only a 50-50 chance of the two galaxies colliding within the next 10 billion years.

Auroras may be visible from Alaska to Massachusetts geomagnetic storm conditions continue.

The planetary nebula is located 3,000 light-years from Earth in the constellation Draco.

Mining craters on the moon could be more practical than extracting precious metals from asteroids, but it might also introduce new legal difficulties

Surprising new fossil evidence undermines the idea that there was ever a mass extinction on land – and may force us to reframe the current biodiversity crisis
