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.

Scientists searching for microbe fossils on Mars have a better idea of what to look for thanks to gypsum that formed when the Mediterranean Ocean dried up over 5 million years ago.

The idea that life on Earth arose through a series of improbable "hard" evolutionary steps may be misjudged, according to a new paper that says our Earth had a big say in matters.

A flash of X-ray light has revealed the existence of an odd couple of stars, a massive star and a white dwarf, that shouldn't really exist together.

By tracking the TV signal back to the plane that was reflecting it towards the Murchison Wide-field Array, astronomers will be able to learn how to remove it from their data.

As the most intense star-forming region in the Local Group, 30 Doradus is of particular importance to astronomers.

Sometimes the end of the mission isn't really the end.

The creation of the belts, and others like it in the future, are a potential new danger to astronauts and satellites headed to geostationary orbit and beyond.
