The universe will most likely end by slowly fading to black over trillions of years. Now a theoretical physicist has calculated the last interesting event that will ever happen: the explosions of stars called black dwarfs, which don’t even exist yet.

Astronomers have spotted a galaxy with a structure similar to the Milky Way. That’s not particularly surprising in itself, but the weird thing is that it's 12 billion light-years away, meaning its far more developed than it should be for its age.

NASA's Transiting Exoplanet Survey Satellite space telescope has now wrapped up the primary phase of its mission, completing an extensive survey of the starry sky that revealed 66 new exoplanets and thousands more candidates.

Science operations have been suspended at the Arecibo Observatory in Puerto Rico after the radio telescope was damaged on Monday August 10. An auxiliary cable supporting a platform appears to have snapped and fallen, damaging the dish.

New analysis of data collected during NASA's Dawn mission has offered some compelling answers to long-standing questions about the makeup of Ceres, starting with presence of a 25-mile-deep reservoir of brine beneath the dwarf planet's surface.

Home to constant turbulent weather and the Great Red Spot – a storm bigger than Earth – Jupiter is the storm capital of the solar system. Now NASA’s Juno mission has discovered two new quirks of these storms – shallow lightning and “mushball” hail.

Phosphorus is a key ingredient for life as we know it, but it’s strangely uncommon in the cosmos. Now astronomers have discovered a new type of star that’s very rich in phosphorus, which could imply that alien life is more common than we thought.

A NASA spacecraft has observed a pulsing glow coming from Mars. Huge spots of ultraviolet light were seen in the night sky, pulsing with uncanny regularity – exactly three times every night. The find highlights the Red Planet's atmospheric processes.

Development of SpaceX's Starship spacecraft that is hoped to carry humans to Mars continues at the company’s Boca Chica site in Texas, where the team just performed a 150-meter (500-ft) hop test of a full-size prototype.

A team of ESA scientists has developed a way to use lasers, special telescopes, detectors, and light filters tuned to specific wavelengths to increase contrast with the sky and accurately track space debris even in broad daylight.

Geological evidence shows that ancient Mars had flowing water. It’s long been thought that its climate was warm and wet, but a new study has found evidence that the planet was instead covered in ice sheets, and much of its water glacier run-off.

Balloons may seem outdated, but for high-flying scientific instruments they’re making a comeback. NASA has now unveiled ASTHROS, a new infrared telescope that will be carried to the edge of space by a balloon the size of a football stadium.
