Where did the famous mystery Wow! signal, detected in 1977, come from? Astronomer Alberto Caballero might have pinpointed the host star. It’s a sunlike star 1,800 light-years away, in the direction to the center of our Milky Way. Source: https://earthsky.org/space/source-of-wow-signal-in-1977-sunlike-star-2mass-19281982-2640123…

Arecibo telescope receiver platform crashes onto dish
The telescope has been inoperable since mid-November, when multiple engineering companies reported that safety in and around it could not be guaranteed. Now their fears have come to pass. No one was injured. Source: https://earthsky.org/human-world/arecibo-telescope-receiver-platform-crashes-onto-dish…
Smile, wave: Some exoplanets may be able to see us, too
Three decades after Cornell astronomer Carl Sagan suggested that Voyager 1 snap Earth’s picture from billions of miles away—resulting in the iconic Pale Blue Dot photograph—two astronomers now offer another unique cosmic perspective: Source: https://phys.org/news/2020-10-exoplanets.html…
Giant ‘survivor’ planet found orbiting dead star
For the first time, astronomers have detected a planet orbiting a white dwarf star. If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars, and some might even remain potentially habitable.

Has microbial life been found on Venus?
Is there microbial life in the atmosphere of Earth’s closest neighbor, Venus? An international team of astronomers has found tentative but highly compelling evidence. Source: https://earthsky.org/space/life-on-venus-phosphine-biosignatures…
The Case for Life on Venus
CNET describes Venus as “a toxic, overheated, crushing hellscape where nothing can survive.” But they reported Friday that one astronomy team’s hypothesis published last month “could prompt a reevaluation of how and where we look for life in the universe.” Carl Sagan speculated about life in the clouds of Venus back in 1967, and just a few years ago, researchers suggested…
Cool! Here’s how Venus would look as a water world
A new map created by a Reddit user – based on what we know about the highs and lows on Venus’ surface – shows what this neighboring, cloud-shrouded, blazing hot planet might look like with oceans. Wow! Source: https://earthsky.org/space/venus-map-with-oceans-on-surface-terraforming…
Stellar pulsations distribute key ingredient for life
As Carl Sagan famously said, “We’re made of star stuff”—but how do stars distribute their essential “stuff” for life into space? NASA’s telescope on an airplane, SOFIA, is finding some answers by watching pulsating stars as they expand and contract, almost like-beating hearts.
