What do redshifts tell astronomers?
A redshift reveals how an object is moving in space and enables astronomers to discover otherwise-invisible planets and the movements of galaxies, and to uncover the beginnings of our universe. Source: https://earthsky.org/astronomy-essentials/what-is-a-redshift…
Why Do We Assume Extraterrestrials Might Want To Visit Us?
Avi Loeb, former chair of the astronomy department at Harvard University and who chairs the Board on Physics and Astronomy of the National Academies, writing at Scientific American: It is presumptuous to assume that we are worthy of special attention from advanced species in the Milky Way. We may be a phenomenon as uninteresting to them as ants are to us;…
Neutrons’ ‘evil twins’ may be crushing stars into black holes
The universe may be filled with “mirror” particles — and these otherwise-undetectable particles could be shrinking the densest stars in the universe, turning them into black holes. Source: https://www.livescience.com/neutron-evil-twins.html
Twisted light from the beginning of time could reveal brand-new physics

Researchers discover the earliest supermassive black hole and quasar in the universe
Nearly every galaxy hosts a monster at its center—a supermassive black hole millions to billions times the size of the Sun. While there’s still much to learn about these objects, many scientists believe they are crucial to the formation and structure of galaxies. What’s more, some of these black holes are particularly active, whipping up stars, dust and gas into glowing…
The magnetic fields swirling within the Whirlpool galaxy
Messier objects are some of the most imaged objects in the universe. In part that’s because many of them are so visibly appealing. A good example of that is the Whirlpool galaxy, M51, which recently received an even more dramatic visual representation with a new photo released by NASA. In it, the magnetic fields that are holding the galaxy together and…
Cosmic beasts and where to find them
Two giant radio galaxies have been discovered with South Africa’s powerful MeerKAT telescope. These galaxies are thought to be amongst the largest single objects in the Universe. The discovery has been published today in Monthly Notices of the Royal Astronomical Society . Source: https://phys.org/news/2021-01-cosmic-beasts.html…
