Perseverance Has Collected Samples from One of the Best Places to Search for Ancient Life on Mars
Scientists with NASA’s Perseverance Mars rover said today that the rover has collected several “tantalizing” organic rock samples from an ancient river delta on the Red Planet. These samples have now been stowed for a planned future mission that hopes to retrieve the specimens and bring them back to Earth for the first-ever sample return from Mars.
A Galaxy With Ten Times the Mass of the Milky Way is Preparing to Become a Quasar
One of the fundamental questions in astronomy is how galaxies formed over 13 billion years ago and have evolved ever since. A common feature that astronomers have noted is that most galaxies appear to have supermassive black holes (SMBHs) at their center – like Sagittarius A*, the ~4 million solar mass SMBH at the center of the Milky Way. These monster black holes occasionally swallow up nearby gas, dust, and stars and emit excess energy as powerful relativistic jets. This phenomenon, where the center of a galaxy outshines the stars in the disk, is known as an Active Galactic Nucleus (AGN) or quasar.
SpaceX missile-tracking satellite launch delayed at least three months

Galactic Superwinds From Supernovae and Newly-Forming Stars Shape a Galaxy’s Early Development
Astronomers have long believed that supernovae and stellar winds drive outflows from galaxies known as superwinds. New research suggests that they may instead be due to a ring of nuclear fire.
