A new kind of magnetic explosion, called forced magnetic reconnection, was seen for the first time in images from NASA’s SDO spacecraft. Learn more in this beautiful video.
Hundreds of thousands of people from 112 countries helped select names for distant exoplanets and their stars. So, for example, the exoplanet formerly known as HAT-P-36b - about 1,000 light-years away - now also carries the name Bran, from an Irish legend.
Using a revolutionary X-ray telescope aboard the International Space Station, scientists have finally created the 1st pulsar surface "map." It shows odd hot spots and suggests that pulsar magnetic fields are more complicated than anyone had assumed.
A new study of the atmospheres of known giant exoplanets suggests that water - an essential ingredient for life - may be common on other worlds in our Milky Way galaxy. At the same, there may be less of it than astronomers once expected.
The 1st interstellar object - 1I/'Oumuamua - had already passed closest to our sun when astronomers first spotted it. So catching this 2nd one - 2I/Borisov - prior to perihelion was a big plus for astronomers! Before and after images here.
There's a supermassive black hole - 4 million times our sun's mass - in the center of our Milky Way galaxy. Astronomers who've measured star movements near this central black hole are now saying there might be a 2nd companion black hole near it.
How did the so-called tiger stripes - huge parallel cracks - form in the icy surface of Saturn's moon Enceladus? A new study from the Carnegie Institution for Science provides some answers.
At least one type of microbe on Earth not only likes to eat meteorites but actually prefers them as a food source, according to a new international scientific study.
The fascinating object 2I/Borisov has been steadily brightening as it nears its encounter with our sun. It'll pass closest to the sun on December 8, 2019, then flee again toward interstellar space.
