Clues to Mars life in Earth’s Atacama Desert
Researchers in the U.S. and Spain have discovered a plethora of previously unknown microbes living in wet clay layers below Chile’s arid Atacama Desert. The finding will help future rovers search for life on Mars. Source: https://earthsky.org/space/microbes-clay-atacama-desert-life-on-mars…
Scientists discover ancient lake bed deep beneath Greenland ice
The ancient lake bed, sealed more than a mile under Greenland ice, may be hundreds of thousands or millions of years old, and contain unique fossil and chemical traces of past climates and life. Source: https://earthsky.org/earth/ancient-lake-bed-deep-beneath-greenland-ice…

Astronomers release a black hole family portrait
“Black hole family portrait” is a fancy way of saying “new catalog.” But it’s a very important and exciting catalog, released October 28, 2020 by gravitational wave astronomers, containing 39 new signals from black hole or neutron star collisions.

NASA’s Probe Sampled Too Much From Asteroid Bennu and Now It’s Leaking
Iwastheone shares some space news from OPB: A NASA spacecraft sent out to collect a sample of rock and dust from an asteroid has nabbed so much that it’s created an unexpected problem. Rocks are jammed in the device in a way that’s keeping a Mylar flap open, creating a gap that’s letting some of the collected pebbles and dust drift…
NASA to announce mysterious moon discovery on Monday
NASA’s upcoming news conference on October 26, 2020 promises “an exciting new discovery about the moon,” with references to the agency’s ambitious Artemis program, a plan to send the first woman and next man to the lunar surface in 2024.

Super-Earth exoplanets often have giant ‘Jupiter’ bodyguards
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.

Technology ready for back-up detector X-IFU in Athena space telescope
In 2031, ESA launches its new X-ray space telescope Athena. SRON Netherlands Institute for Space Research plays a large role in building one of its two instruments, the X-IFU spectrometer, by producing the camera plus the back-up detectors. SRON scientists have now successfully developed detectors that are optimized for a readout based on a special system called Frequency Domain Multiplexing. They…
