Metals from Space Junk Are Polluting Earth's Upper Atmosphere

Falling pieces of space debris could be altering the stratosphere and negatively impacting our climate, new research suggests.

Suspected Interstellar Signal May Have Just Been a Noisy Truck

Something much closer to home may be behind the seismic signals purported to be caused by an interstellar meteor falling to Earth 10 years ago.

Scientists found astonishing link between Mars and Earth

Study reveals that deep-sea currents have been weakening, strengthening during 2.4m-year climate cycles

Juno measures oxygen production on Europa

Using NASA’s Juno spacecraft, scientists have calculated the rate of oxygen production on Jupiter’s moon Europa — the first time any spacecraft had directly measured charged oxygen and hydrogen particles from the moon’s atmosphere.

The LIFE telescope passed its first test, detecting biosignatures on Earth

The vast majority of exoplanets are uninhabitable. For the few that may be habitable, we can only determine if they are by examining their atmospheres. LIFE, the Large Interferometer for Exoplanets, can help.

Planetary System Probed For Signs of Alien Technology

Some 100 light-years from the Solar System dwells the most mathematically perfect planetary system we've ever seen. The star at its center – a temperate orange dwarf called HD 110067 – is orbited by six exoplanets.

The Most Epic Pair of Supermassive Black Holes Ever Seen

A galaxy some 750 million light-years away has been discovered hosting the heftiest pair of supermassive black holes we've ever seen.

We Finally Know What Turned The Lights on at The Dawn of Time

According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic dawn were small dwarf galaxies that flared to life, clearing the fog of murky hydrogen that filled intergalactic space.

Camera Inside Varda's Space Capsule Captured Its Wild Trip Back to Earth

Here's a front row seat on what it would be like to return to Earth inside a space capsule.

Astronomers spot water vapor in region where planets likely form

Astronomers have found water vapor around a young star within the constellation Taurus, 450 light-years away from Earth.

The Metal Scar of a Devoured Planet

A white dwarf star that devoured at least a chunk of one of its planets has been betrayed by a scar of vaporized metal marring it surface – the tell-tale remnants of the planet that once orbited the star before spiraling into its doom.

Alien Civilizations May Be Trapped on Their Home Worlds

Spanish professor argues that that water or other liquid-dwelling aliens, as well as civilizations on super-Earths, may actually be trapped on their planets due to "physical limitations".

A Close Look at a 13 Billion Year Old Galaxy Reveals It Shouldn't Exist

NASA's new space telescope spotted a 13 billion-year-old galaxy that is much too complex to exist that early in the Universe.

Japan moon lander put to sleep after surviving lunar night

Japan's moon lander has been put back to sleep after it surprisingly survived the freezing, two-week lunar night, the country's space agency said, with another operation attempt scheduled for later this month.

Saturn's largest moon most likely uninhabitable

A study shows the subsurface ocean of Titan—the largest moon of Saturn—is most likely a non-habitable environment, meaning any hope of finding life in the icy world is dead in the water.
