Mars dust storm grows global

The storm is now officially “planet-encircling.” At Gale Crater, where the Curiosity rover is studying the storm’s effects, dust has starkly increased. Meanwhile, the Opportunity rover stays silent.

10 things about Martian dust storms

Mars’ massive dust storms have been challenging – and enticing – scientists for decades. From NASA, here’s the scoop on Martian dust.

Video: Watching solstices and equinoxes from space

See how sunlight falls on Earth’s surface during the solstices and equinoxes, and get a better understanding of why Earth’s tilt causes the seasons.

Astronomers see a black hole eating a star

Astronomers now have the 1st direct image of a black hole ripping apart a star. The star-stuff goes into a disk surrounding the hole, and it’s also ejected back to space in powerful jets.

Life at Alpha Centauri? Maybe, NASA says

Could life exist on planets in the star system closest to ours, Alpha Centauri? Dangerous X-ray radiation makes it unlikely for the single exoplanet found so far. But new data suggest better odds for any new planets yet to be discovered.

A giant dust storm is raging on Mars

One of the thickest dust storms ever seen on Mars has been spreading since early June. The Opportunity rover – 1 of 2 active rovers on Mars – has suspended science operations.

ALMA spies 3 planets around a young star

Astronomers have evidence for 3 infant planets forming in a disk around a newborn star. They say their new observing technique could find some of the youngest planets in our galaxy.

Watch spacewalk June 14

On Thursday, 2 astronauts aboard the International Space Station will conduct a 6 1/2 hour spacewalk. NASA’s live coverage begins at 10:30 UTC (6:30 a.m. EDT). The spacewalk itself is scheduled to start at 12:10 UTC (8:10 a.m. EDT).

The strange case for life in other universes

More about the mind-boggling new studies suggesting that there could be many parallel universes beyond our own, where life is able to flourish.

From pulsar to magnetar? Or vice versa?

Since the 1970s, scientists have treated pulsars and magnetars as 2 distinct populations of objects. Now they think they might be stages in a single object’s evolution. A new NASA ScienceCast has more.

Top 10 space objects to see during the day

Love astronomy, but don’t like to stay up late? Here are 10 space objects you can see – under the right conditions – during the day.

No Planet Nine? Collective gravity might explain weird orbits at solar system’s edge

Astronomers have been searching for a Planet Nine – a world about 10 times Earth’s mass – for about 2 years and have yet to spot it. Maybe there’s another explanation?

Rover finds 2 new life clues on Mars

“Are there signs of life on Mars? We don’t know, but these results tell us we are on the right track.”

More mystery objects near Milky Way’s giant black hole

Astronomers call them G-objects. The 2 previously known ones came incredibly close to the Milky Way’s central black hole, yet survived. Now astronomers report 3 more of these mystery G-objects near the heart of our galaxy.

Let NASA take you on a virtual trip to exoplanets

Exoplanets are worlds orbiting distant stars. Until recently, they existed only in the realm of imagination and probability. Now we know thousands! NASA’s Exoplanet Travel Bureau lets you explore them.

New Horizons is awake!

New Horizons is boldly exploring where no spacecraft has before. It’s the craft that swept past Pluto in 2015. Now it’s preparing for its next encounter on January 1, 2019.

Dunes on Pluto? Yes, but made of methane ice

The discovery of methane dunes on Pluto is an indication of another way in which this planet mimics Earth, but in a way that is utterly unique and alien.

Globular clusters not as old as thought?

New research suggests that globular clusters – once thought to be nearly as old as the universe itself – aren’t that old, after all. They might be only around 9 billion years old.

These distant moons may harbor life

Astronomers have identified 121 giant exoplanets whose moons might be capable of supporting life.
