New findings suggest that Saturn’s rings formed only 10 to 100 million years ago, during the earthly age of the dinosaurs.

Here’s an alternative explanation to the Planet 9 hypothesis, the idea that a large undiscovered planet in the outer solar system is pulling on some small outer worlds, distorting their orbits.

For the 1st time ever, plants were sprouted on the moon – but didn’t survive long – as part of a biosphere experiment on China’s Chang’e-4 lander.

Our sun’s planets orbit in a plane extending from the sun’s equator. Astronomers have found a double-star system whose planet-forming disk has flipped up – perpendicular to what we’d expect – over the poles. What would nature be like on one of these worlds?

New observations of Venus’ atmosphere by the Japanese orbiter Akatsuki – combined with supercomputer simulations – have revealed giant symmetrical streaks never seen before.

Saturn’s largest moon Titan is enveloped in a thick atmosphere, but the infrared camera on the Cassini spacecraft was able to reveal the moon’s myriad of surface features.

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.
