The young sun-like star TW Hydrae is showing signs that a massive exoplanet is forming within its protoplanetary disk.

The Campo del Cielo meteor shower fell over 4,000 years ago, now one of the largest chunks has been dredged from the dirt.

Hubble spies a beautiful supernova remnant that was triggered by one greedy white dwarf.

As speculation about a possible Earth-like exoplanet around our sun's nearest neighbor reaches fever pitch, the European Southern Observatory says there will be an announcement on Wednesday.

As we get better at studying atmospheres on alien worlds, we'll need to keep in mind that the detection of oxygen doesn't necessarily point to extraterrestrial biology.

This month we could find out Earth's "twin" is orbiting our nearest stellar neighbor.

The colliding black holes that generated the first detection of gravitational waves may have been primordial.

Looking in craters for signs of Mars life may not be the biological goldmine we hoped.

"Tabby's Star" has dramatically dimmed and we don't know why.

As gravitational wave observatories become more sensitive, we may see the collisions of neutron stars and, possibly, find out what these stellar husks are really made of.

Stars usually form in dense stellar nurseries with many other stars for company, but a baby star has been found by itself, erupting in a void with no siblings in sight.

The famous 87-year-old telescope at Lowell Observatory that was used to discover Pluto needs to be renovated so it can seek out the dwarf planet once more.

Alien worlds orbiting within the habitable zones of small red dwarf stars may become truly habitable if their atmospheric circulation balances the temperature extremes.

The Very Large Telescope's GRAVITY instrument is online and already gathering data from the extreme environment surrounding our galaxy's supermassive black hole, Sagittarius A*.

The NASA mission will enter Jupiter orbit on July 4, but little is known of arguably the most dangerous region in the solar system.

Remove the singularity and a wormhole appears in the center of a black hole — but is it traversable?

Strange plumes have been spotted high in the Martian atmosphere that have, so far, defied explanation. Now scientists think space weather is to blame.

A beautiful atmospheric phenomenon descended over the ESO's Very Large Telescope (VLT) last week, giving the participants of the inaugural #MeetESO social media event an evening treat.

As the Mercury transit unfolded over the Atacama Desert, astronomers remembered the pioneering calculations that were made to begin to understand the scale of the universe.

A strange pattern of starspots has been mapped on a nearby massive star, revealing just how different other stars are to our own sun.

From May 7, Discovery News will be in the Chilean Atacama Desert to visit the European Southern Observatory's sites and observed the Mercury Transit.

By studying reflected light from a young star system, astronomers have precisely measured the size of the innermost gap between the star and where planets will eventually form.

The protective covers have been removed from the James Webb Space Telescope's mirrors at a NASA cleanroom, showing off the next-generation space telescope's golden beauty.
