At last, a planet for Barnard’s Star

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.

Here are 6 reasons to study asteroids and comets

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

Wow! Amazing timelapse of Beta Pictoris b

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.

How did Earth get its water?

For decades, scientists have said that at least some of Earth’s water came from comets and asteroids. New research suggests an even more primordial source, the vast cloud in space from which our world formed.

How to see Venus in daytime

Another time of greatest brilliancy is coming up for Venus, when many spot this brightest of planets in a blue daytime sky. Here’s how you might try it.

Awesome new Jupiter close-up

This new Juno spacecraft image shows magnificent swirling clouds in Jupiter’s dynamic atmosphere. The craft was about 4,400 miles (7,000 km) from the planet’s cloud tops on October 29, over about 40 degrees north.

Synchronized telescopes put limits on mystery bursts

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

Astronomers find largest-yet galaxy proto-supercluster

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

Did natural batteries create Mars’ organic carbon?

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.

Galaxy-scale fountain seen in full glory

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

Best comet of 2018 is approaching

Comet 46P/Wirtanen isn’t bright in any absolute sense. It currently requires a telescope to be seen. But it’s getting brighter and might reach visibility to the eye alone before the end of 2018.

Here’s where Mars InSight will touch down November 26

“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.”

Curiosity rover on the move again

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.

One of the oldest stars in the universe

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.

E.T., we’re home!

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?

Could ‘Oumuamua be an alien lightsail?

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.

Lucy mission to Jupiter’s Trojans gets the nod from NASA

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 US and Europe take a next step toward the moon

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.

Timelapse shows 25 years of Supernova 1987A

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.

Dusk for Dawn mission to asteroids

NASA’s Dawn spacecraft has gone silent. The mission to explore the 2 largest bodies in the asteroid belt, Vesta and Ceres, is at an end.
