Been Studying alternatives to Dark Matter and the rabbit hole has led me to MOG/STVG by John Moffat. The video I’m sharing is a long and great interview by Curt Jaimungal with Moffat. There are plenty of MOND-like alternatives to Dark Matter and all may be proven wrong should science make further progress discovering Dark...

[…]to accurately interpret some of the neutron stars’ signals, researchers must first understand what goes on inside them. They have their hunches, but experimenting directly on a neutron star is out of the question. So scientists need another way to test their theories. The behavior of matter in such a superdense object is...

Gravitational wave astronomy is such a boon in detecting these types of events early. One of the few consistently positive things to be alive with right now....

NASA’s album of images and renditions so far from JWST for 2023. Great for wallpapers, screens savers, posters, or just about anything.

Another great visualization and the effects of gravity on each planet. Fun stuff!

Researchers using NASA’s James Webb Space Telescope have made major strides in confirming the source of dust in early galaxies. Observations of two Type II supernovae, Supernova 2004et (SN 2004et) and Supernova 2017eaw (SN 2017eaw), have revealed large amounts of dust within the ejecta of each of these objects. The mass found...

Stars are thought to form within enormous filaments of molecular gas. Regions where one or more of these filaments meet, known as hubs, are where massive stars form....

I love the show One Strange Rock, I know Will Smith has pretty much lost his noodle, but c’mon, couldn’t there be a different host and still listen to the astronauts? Has @astropettit made it here yet? Are there any other shows that offer a look from the astronauts point of view?

Astronomers across the world announced on Thursday that they have found the first evidence of a long-theorised form of gravitational waves that create a "background hum" rumbling throughout the universe.

In their jiggles and shakes, red giant stars encode a record of the magnetic fields near their cores.

This video, a scientific visualization of the galaxies captured as a part of the CEERS (Cosmic Evolution Early Release Science) Survey, showcases a large undertaking by NASA’s James Webb Space Telescope. It flies by thousands of galaxies, starting with those nearby and ending with less-developed galaxies in the very distant...
