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.

The bacteria, Sporosarcina pasteurii, is able to make calcium carbonate that can act as a sealant to fix bricks made from lunar regolith.

Constructing solar arrays out of moon dust would reduce launch costs and make lunar bases more plausible, according to a new study.

A fall of rare meteorites in Costa Rica has revealed new details about a similar space rock that fell in Australia 50 years earlier.

Europe's Solar Orbiter spacecraft has chronicled the development of the magnetic escape of plasma driven out by a powerful magnetic reconnection event.

A newly found super-Earth could help provide answers as to why there are hardly any planets twice the diameter of Earth.

The nova is ignited when a "vampirific" white dwarf steals too much matter from a companion star.

While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical signatures of past life, if it ever existed.

JWST could potentially detect the signature of methyl halide compounds, produced by microbial life in Earth's ocean, on hypothetical hycean exoplanets.

The dream of a flat, lightweight telescope lens, where microscopic etchings precisely refract different wavelengths of light, is here.

Researchers examining seismic data recorded on Mars say the have found evidence supporting the presence of liquid water deep inside the Red Planet.

This butterfly shaped nebula is the perfect target for the James Webb Space Telescope to learn more about star formation.

After many previous claims and false alarms, astronomers can finally confirm the existence of at least four planets less massive than Earth orbiting Barnard's Star.

Europe's HERA mission has taken a good look at Mars and its moon Deimos on its way to explore the aftermath of the DART impact in the Didymos–Dimorphos asteroid system.

Natural cycles in Earth's rotational axis and its orbit around the sun drive climatic changes, and now researchers have matched up specific points in those cycles to the timing of ice ages.

The total lunar eclipse on March 13-14 will plunge moon missions into darkness. What will happen to the lunar spacecraft?

A family portrait of the Andromeda galaxy and its orbiting dwarf satellites raises questions about how galaxies evolve.

A new mission designed to better understand the heliosphere will be the first to map in three dimensions how the solar corona becomes the solar wind.

The Lucy mission to Jupiter's Trojan asteroids is currently cruising through the Asteroid Belt, and will fly close to asteroid Donaldjohanson in April.
