The notebook-sized module will get another orbital test soon.

The results are finally in for the first chocolate chip cookie bake-off in space.

European Space Agency (ESA) researchers have begun extracting oxygen from simulated moon dust. A reclamation plant has been built at the European Space Research and Technology Centre (ESTEC) in the Netherlands

Material falling into a black hole casts X-rays out into space—and now astronomers have used the echoes of this radiation to map the dynamic behavior and surroundings of a black hole itself. Most black holes are too small on the sky for us to determine their immediate environment, but we can still explore these mysterious objects by watching how matter behaves as it nears, and falls into, them.

European researchers are working on a system that can churn out breathable oxygen from simulated samples of moon dust. “Being able to acquire oxygen from resources found on the Moon would obviously be hugely useful for future lunar settlers, both for breathing and in the local production of rocket fuel,” explained Beth Lomax, a chemist from the University of Glasgow, in an European Space Agency (ESA) press release.

Engineers have been trying to crack this problem since the ’80s.

Yarrabubba Crater was blasted out by an asteroid or comet about 2.23 billion years ago.

A team of Canadian astronomers have played a key role in locating a second fast radio burst, a crucial step in identifying what causes these mysterious signals from outside Earth's galaxy.

Every season has its characteristic star constellations in the night sky. Orion—one of the most recognizable—is distinctly visible on crisp, clear winter nights in the northern hemisphere. The constellation is easy to spot even in light-polluted cities, with its bright stars representing the shape of a person.

Whether you are a telescope enthusiast or just want to step outside to enjoy the night sky, these are the phenomena to look out for this year

Just as astronomers thought they were making sense of fast radio bursts (FRBs) — the mysterious repeating signals originating deep in space — the universe threw us a curveball.

Scientists generally agree that the best strategy for finding extraterrestrial life is to look for a world that has conditions similar to Earth’s, including atmospheric oxygen that could be produced by organisms running photosynthesis. But current instruments used to study potentially habitable exoplanets are woefully ill equipped to find such biosignatures.

The TESS space telescope has found its first Earth-sized planet with conditions that might be right for life orbiting a small star 100 light-years away

For over 50 years, humans have tried to pull back the thick clouds of Venus to study its surface. Most observations have tapped the long wavelengths of radar to pierce the cloud layers. Now, scientists have combined long-term radar observations of the planet’s surface to try to clarify a longstanding mystery behind the length of Venus' day.

NASA's planet-hunting mission TESS has found its first potentially habitable exoplanet the size of Earth orbiting a star about 100 light-years from Earth, according to the agency. The findings were announced during the 235th meeting of the American Astronomical Society on Monday in Honolulu.

When searching for dark matter, astronomers must go on a sort of "ghost hunt." That's because dark matter is an invisible substance that cannot be seen directly. Yet it makes up the bulk of the universe's mass and forms the scaffolding upon which galaxies are built. Dark matter is the gravitational "glue" that holds galaxies as well as galaxy clusters together. Astronomers can detect its presence indirectly by measuring how its gravity affects stars and galaxies.

These aren't Milky Way stars.

After months of anticipation, SpaceX's new crew-worthy spacecraft, Crew Dragon, is finally prepped for its last major test before astronauts can begin using it for rides to the International Space Station. But finding the right weather conditions could be a roadblock this weekend.

NASA scientists completed field tests in November of a floating rover they hope will one day travel to Europa, the frozen ocean moon of Jupiter.

Big and small rockets. The Moon and Mars. Lots of asteroid stuff, too.
