Found: Dying Galaxies Containing Active Black Holes

Found: Dying Galaxies Containing Active Black Holes

Astronomers combined observations of far distant galaxies exhibiting no signs of star formation and found active supermassive black holes that may have contributed to the evolution of their parent galaxies. Plus, rocket launches, detecting earthquakes, and why Uranus and Neptune are different shades of blue.

A Trio of Mars Papers Provides Two Explanations to Different Questions

A Trio of Mars Papers Provides Two Explanations to Different Questions

Today, we take a look at three recent papers attempting to explain various phenomena on Mars. One uncovers the cause of discrete aurorae. Another explains the martian haze. And a third actually ends up with more questions than answers. Plus, Boeing’s OFT-2 returns to Earth, ESA’s Solar Orbiter makes its closest approach, and Dr. Pamela reviews the new graphic novel “Galaxy: The Prettiest Star” by Jadzia Axelrod.

Tau Herculids Meteor Shower Could Be Meteor Outburst

Tau Herculids Meteor Shower Could Be Meteor Outburst

Due to the gravitational pull of Jupiter on the fragments and dust of comet 73P/Schwassmann-Wachmann, Earth’s orbit may be moving through a dense portion of the comet’s trail on May 31. This alignment could result in an unusually spectacular meteor outburst, and we’ll interview astronomer Pierre Martin about this possible event. Plus, a SpaceX launch that wasn’t Starlink, a new solar sail, and JWST.

Active Black Hole’s Surge in Brightness Due to Magnetic Flip

Active Black Hole’s Surge in Brightness Due to Magnetic Flip

A luminous black hole already classified as an active galactic nucleus brightened suddenly in recent ground and space observations, and the cause may be due to a sudden flip in the magnetic poles. Plus, community science, rockets, Ingenuity, and an interview with Dr. Cathy Weitz from Planetary Science Institute.
