A survey of the stellar nursery in the Orion Nebula Cluster provides evidence that stars compete for material and their size depends on what they gather rather than their initial core size. Plus, NASA mission updates, fast radio bursts, neutron stars, visible novae, and mountain building in the Andes.

Another Potential Dark Matter Particle Isn’t Found

Apr 20, 2021 | Cosmology, Dark Matter, Earth, Galaxies, Physics, Supermassive Black Holes

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.

Exoplanetary Atmospheres and How to Understand Them

Apr 19, 2021 | Asteroids, Astrobiology, Daily Space, Earth, Exoplanets, Moon, Physics, Sky Watching, Stars, The Sun

Today’s news examines many of the ways in which scientists are trying to understand Earth’s atmosphere as well as the atmospheres of exoplanets, mostly in the hopes of figuring out the best way to tell if there is life on another world. Plus, sixty years of fusion power and this week’s What’s Up.

X-ray Surges Found Along With Radio Bursts From Crab Nebula

Apr 17, 2021 | Astrobiology, Daily Space, Earth, Exoplanets, Galaxies, Nebulae, Neutron Stars / Pulsars, Quasar, Spacecraft

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.

Strong Evidence Found That Muons Deviate From Standard Model

Apr 15, 2021 | Asteroids, Book Club, Cosmology, Curiosity, Daily Space, Earth, ESA, Mars, Physics

Fermilab released the first results of their Muon g-2 experiment this week, and the fundamental particles don’t behave as predicted by the Standard Model of Particle Physics. Plus, dust, more dust, Martian water (again), and a review of Packing for Mars by Mary Roach.

Not Surprising Anyone, Satellite Proliferation Contributes to Light Pollution

Apr 12, 2021 | Comets, Daily Space, Earth, Galaxies, Mars, Quasar, Sky Watching, Starlink, Supermassive Black Holes, Uranus

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.
