Planetary systems with both super-Earths and Jupiter-type planets may be common, according to a new study. As in our own solar system, the giant planets would act as “bodyguards” protecting the smaller planets from asteroid impacts.
Are there worlds out there – orbiting distant stars – even better suited for life than Earth? Might they be older, larger, warmer, wetter and with longer-living stars? Now astronomers have identified 24 possible superhabitable worlds.
Astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon – known as a tidal disruption event – is the closest such flare recorded to date at just over 215 million light-years from Earth.
Scientists with the European Space Agency say that the Mars Express orbiter has found evidence of three more salty lakes below Mars’ south pole. The discovery comes two years after the first lake was detected in 2018.

After 2 weeks of scrubs, SpaceX’s Falcon 9 rocket blasted off October 6, 2020, carrying 60 more Starlink satellites to orbit. The rocket successfully landed at sea 9 minutes later. Video of the launch and landing here, plus steps taken to reduce the bright satellites’ effect on astronomy.
For the first time, astronomers have obtained an image of the very young gas giant exoplanet Beta Pictoris c, 63 light-years away. Its sibling, Beta Pictoris b, was discovered and photographed in 2008.
All these years, NASA scientists have laboriously sifted through spacecraft images to identify and classify markings on Mars. Now they’re using a new “classifier,” powered by artificial intelligence. What takes a human 40 minutes takes the AI tool an average of just 5 seconds.
