Simultaneously cooling Pluto while energizing atmospheric molecules to allow them to escape into space, Pluto's haze plays a key role in the planet's energy balance.

With 10 times the mass of our planet, and spending only part of its orbit in the habitable zone, Kepler-725c is very different to Earth.

A giant exoplanet is surprisingly chill given how close it is to its red dwarf star — perhaps because the star is so little.

Built on a set in a specialist facility in Germany, a mockup of a lunar landscape is helping imaging experts learn how to take better images and video footage on the moon.

The core of the Red Planet may be filled with sulfur.

A newly found object could be a dwarf planet that contradicts the Planet Nine hypothesis.

The presence of water-ice in the debris disk around a young star could have helped facilitate the growth and development of exoplanets.

Scientists have found a neutrino that could come from a gamma-ray burst, an active black hole or a collision between a cosmic ray and photons in the cosmic microwave background.

The Wolf Amendment, a law that prevents bilateral cooperation in space research between the U.S. and China, is preventing U.S. government-funded analysis of the Chang'e 5 moon samples.

The idea was first hypothesized about 70 years ago.

Every time this doomed star plunges through a supermassive black hole's accretion disk, it loses orbital energy and triggers a burst of X-rays.

The interior of asteroid Vesta has been shown not to be a protoplanet after all, meaning that new explanations for its origin are needed.

Luke found life on Tatooine to be boring, but he should be glad, because as we have seen, binary stars have the potential to play all kinds of havoc on their orbiting circumbinary planets.

An object seen to have moved in the time between when it was imaged by the IRAS and AKARI surveys in 1983 and 2006 respectively could be Planet Nine.

NASA's mission to Jupiter has revealed new findings about the giant planet and its volcanic moon.

Data from Europe's Gaia spacecraft have revealed that a cluster of 1,000 stars is breaking up much faster than is normal, stumping astronomers.

A newly found, huge cloud near our solar system probably won't form stars, but will rather disperse as part of a feedback cycle that regulates star formation.

Our sun is wobbling, and this has a huge impact upon the regularity of many of Earth's meteor showers, according to a new study.

By teaming up with the James Webb Space Telescope, or by scientists delving into its long history of observations, Hubble is cementing its legacy.

The Andromeda galaxy's family of satellite galaxies point towards the Milky Way, and nobody knows why.

A fog of long-wavelength infrared light could be produced by dusty, star-forming galaxies that have remained hidden — until now, that is.

An AI algorithm designed to look for planetary systems that could host Earth-like, habitable zone planets, has found 44 candidates.

The James Webb Space Telescope has revisited a star that swallowed a planet and found that instead of the star subsuming the planet, it was the planet that crashed into the star.

Analysis of samples brought back from the farside of the Moon by the Chang'e 6 mission have found the water content of the lunar farside mantle is much more depleted compared to the nearside.

The LIFE mission would feature four space telescopes acting together to search for biosignatures on rocky planets in the habitable zones of their stars.
