Researchers find that the “oddball supernova” of a curiously cool, yellow star was lacking the hydrogen content expected, “stretching what is physically possible.” Plus, finding potentially habitable planets, a gamma-ray burst, ash clouds, and a new lunar map in this week’s What’s Up.
On March 5, 2021, three separate, large earthquakes occurred within hours of each other near New Zealand, and all three produced a tsunami. The resulting changes in wave height were recorded with special buoys. Plus, a radar blackout at Mars, a giant planet growing, small galaxies in the early Universe, and what even is a day?
The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.
Researchers looked for a slowdown in black hole rotational speeds due to the collection of ultralight bosons, but they found nothing, eliminating the hypothetical particle from the list of possible dark matter particles. Plus, neutrino hunting, neutron stars, a space hurricane, and our review of some delightfully nerdy apparel.
Data analyzed from the NICER telescope aboard the ISS contains evidence of X-ray boosts accompanying radio burst detections, releasing more energy than expected as “giant radio pulses”. Plus, machine learning, intraterrestrial life, all the volcanoes, and updates on SN15 and Ingenuity.
A new study examined the effects of recent increases in the number of space objects orbiting Earth and found that the proliferation of satellites contributes to a nearly ten percent increase over natural lighting of the night sky. Plus, Mars, Uranus, Neptune, ancient Earth, volcanoes, and our weekly What’s Up segment.
