Climate change is a leading problem in today’s society, and today we have a quartet of stories on its effect on the world around us. Plus, more coverage from the AAS meeting with three stories on black holes, as well as dating supernovae, breaking a star, and magnetic chaos in a galaxy.

Powerful GRB is Actually Giant Flare From Magnetar in Nearby Galaxy

Multiple international teams determine that a 2020 gamma-ray burst was actually a giant flare from a magnetar and that flare originated from a nearby galaxy. Plus, the Dark Energy Spectroscopic Instrument is ready for a new survey, NASA extends two planetary missions, and What’s Up in the night sky this next week.

Rocky Planet Found Orbiting Extremely Old Milky Way Star

Jan 13, 2021 | AAS, Daily Space, Exoplanets, Galaxies, Gemini North, Kepler, Neutron Stars / Pulsars, Physics

Researchers using NASA’s TESS and the Keck Observatory found a rocky planet orbiting a 10-billion-year-old star in the Milky Way, up in the galaxy’s thick disk. Plus more planetary news from the AAS Winter Meeting, a magnetar, colliding galaxies, and gravitational wave news.

Hubble Space Telescope Releases Galaxy Merger Montage

Hubble celebrates the new year with a release of six gorgeous galaxy mergers, imaged as a part of their investigation into star formation rates in such systems. Plus, a weird nebula, a big flare from a tiny star, wind on a brown dwarf, and more.

Primordial Black Holes, Dark Matter, and… the Multiverse?

Jan 6, 2021 | Active Galaxies, Astrobiology, Cosmology, Daily Space, Earth, ESA, Mars, Science, Space History, Stars

Theoretical physicists have found a way to possibly detect primordial black holes which could lead to answers about dark matter and maybe even the existence of a multiverse. Plus the age of the Universe, a wobble in Mars’ axis, and that pesky candidate signal from Proxima Centauri.

Missing Black Hole Continues to Mystify Scientists
