Of the more than 60 Fast Radio Bursts found so far, only one has ever been seen to repeat from the same source ... until now.

Last week, citizen scientists with Zooniverse's Exoplanet Exoplorers announced K2-288Bb - a type of exoplanet considered rare so far. The finding might shed new light on how planets form.

Astronomers are arguing over a brief and unusual flash in the night sky from earlier this year. The call it the Cow. One group argues it was a monster black hole shredding a passing star. The other argues it might have been a black hole being born.

Barnard b is one of the nearest planets to our sun at only 6 light-years away. But its host star is dim. Can life find a way on such a cold planet?

Astronomers now have the 1st direct evidence that white dwarf stars form crystal cores. Our sun is destined to become a crystal white dwarf in about 10 billion years.

Rovers on Mars today are amazing, but slow, and still mostly controlled by humans back on Earth. Europe is testing new self-driving software to help future Mars rovers travel faster and farther each day.

It shines with a brightness equivalent to 600 trillion suns. "We don’t expect to find many quasars brighter than that in the whole observable universe," said the astronomers.

Astronomers see many breathtaking merging galaxies, with their giant tidal streams of stars and unusual shapes. But some normal-looking galaxies might be merging, too. Now astronomers have a new tool to find out.

A new study analyzes pulses of radio waves coming from a magnetar - a rotating, dense, dead star with a strong magnetic field - located near the supermassive black hole at the heart of the Milky Way.

And hello, Iridium NEXT. The final launch of 10 Iridium NEXT satellites is targeted for January 8, 2019, at 7:48 a.m. PST. Meanwhile, the beloved glints of Iridium flares are disappearing from Earth's night skies.
