Astronomers are “99 percent confident” that this exoplanet is real and not a false detection. The planet for Barnard’s star – 2nd closest star system to our sun – appears to be a cold super-Earth.

First, asteroids can serve as pit stops – and provide resources – for future space exploration. Second, some asteroids or comets may be hazards to Earth.

Not long ago, we couldn’t see planets orbiting distant stars at all. Now astronomers have captured the passage of exoplanet Beta Pictoris b into the glare of its star … then its re-emergence 2 years later.

A technological tango between 2 telescopes in the Australian outback has added an important piece to the puzzle of fast radio bursts.

Astronomers have identified a gigantic proto-supercluster of galaxies forming in the early universe, just 2.3 billion years after the Big Bang.

Earlier in 2018, the Curiosity rover found evidence for abundant organic compounds – those containing carbon – on Mars. Does this mean Mars once had life? Or can some other process can explain it? Here’s one idea.

At the core of the giant elliptical galaxy Abell 2597, a supermassive black hole is powering the cosmic equivalent of a gargantuan, ongoing fountain.

“If you were a Martian coming to explore Earth’s interior, it wouldn’t matter if you put down in the middle of Kansas or the beaches of Oahu … The beauty of this mission is happening below the surface.”

NASA’s Mars Curiosity rover drove about 197 feet (60 meters) over this past weekend to a site called Lake Orcadie. This was Curiosity’s longest drive since experiencing a memory anomaly on September 15.

The star could be only a single generation removed from the Big Bang. It’s the new recorder-holder for having the fewest “metals,” that is, the fewest of the heavier elements made inside stars and released to space via supernovae.

A new study from MIT suggests that existing laser technology could be used to signal alien astronomers on a distant world. But should it be used?

The object we call ‘Oumuamua entered our solar system a year ago and quickly left again. It’s a very puzzling object. Could it be an alien lightsail? A new paper from Harvard discusses that possibility.

There are perhaps as many Trojan asteroids orbiting 60 degrees ahead of and behind Jupiter as in the asteroid belt between Jupiter and Mars. Now NASA has given a go-ahead for the 1st mission to Jupiter’s Trojans.

The European Service Module – eventually to be used to power and propel NASA’s Orion spacecraft in the 1st manned moon mission since the 1970s – leaves Europe today and arrives in the U.S. tomorrow.

If you were alive and interested in astronomy then, you’ll remember Supernova 1987A, the 1st supernova visible in Earth’s skies since 1604. The new timelapse shows its aftermath over a 25-year period, 1992 to 2017.
