The 70-Year-Old Mystery of Two Galactic Mushroom Clouds

The 70-Year-Old Mystery of Two Galactic Mushroom Clouds Giant bubbles hovering over the Milky Way seem to be remnants of an ancient explosion. Jeremy Sanders, Hermann Brunner and the eSASS team (MPE); Eugene Churazov, Marat Gilfanov (on behalf of IKI) When Peter Predehl, an astrophysicist at the Max Planck Institute for Extraterrestrial Physics in Germany, first laid eyes on the new map of the universe’s hottest objects, he immediately recognized the aftermath of a galactic catastrophe. A bright-yellow cloud billowed tens of thousands of light-years upward from the Milky Way’s flat disk, with a fainter twin reflected below.

Planet Earth Report --"Unknown World of Giant Viruses to Harvard Astronomer says Expect the Unexpected"

Harvard astronomy professor Avi Loeb’s highly anticipated new book, “Extraterrestrial”,: The First Sign of Intelligent Life Beyond Earth,” is being published Jan. 26, detailing his controversial theory that an artificial object may had been sent to Earth in 2017 from an extraterrestrial civilization. New York Times best selling author Alan Lightman called “Extraterrestrial” provocative “and thrilling” and praising Loeb for asking readers to “think big and to expect the unexpected,” reports The Boston Globe.

Astronomers Detect Large-Scale X-Ray Bubbles in Milky Way's Halo | Astronomy

Astronomers using the eROSITA X-ray telescope onboard the Spektrum-Roentgen-Gamma (SRG) observatory have detected X-ray-emitting bubbles that extend approximately 14,000 parsecs (45,662 light-years) above and below the central region of our Milky Way Galaxy. This image from the eROSITA X-ray telescope shows the energetic Universe.

Launched in July 2019, eROSITA is a large-collecting-area and wide-field-of-view X-ray telescope. Over the course of six months, from December 2019 to June 2020, it has completed a survey of the whole sky. A preliminary analysis of the all-sky survey map indicated that more than one million X-ray sources were detected by eROSITA. This is comparable to, and may exceed, the total number of X-ray sources known before this telescope launched.
