The First Black Hole Ever Discovered is More Massive Than We Thought
Neel V. Patel, writing at MIT Technology Review: Einstein first predicted the existence of black holes when he published his theory of general relativity in 1916, describing how gravity shapes the fabric of spacetime. But astronomers didn’t spot one until 1964, some 6,070 light-years away in the Cygnus constellation. Geiger counters launched into space detected cosmic x-rays coming from a region…

Deepest land-dwelling microbes found at bottom of 5km hole in China
Microbes at the bottom of the third deepest hole in the world may be surviving life at 137°C, which would extend life’s known thermal tolerances Source: https://www.newscientist.com/article/2268428-deepest-land-dwelling-microbes-found-at-bottom-of-5km-hole-in-china/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
First black hole ever detected is more massive than we thought
New observations of the first black hole ever detected have led astronomers to question what they know about the Universe’s most mysterious objects. Source: https://phys.org/news/2021-02-black-hole-massive-thought.html…
The search for electron-hole liquids gets warmer
An electron-hole liquid is a unique collective quantum state formation in semiconductors where free charges can condense into a droplet. These droplets have interesting uses for laser-controlled circuits based on light beams instead of wires. Unfortunately, electron-hole liquids normally only exist in extremely cold environments, and aren’t practical for real devices. But what if these droplets could instead form as the…
What is the Milky Way?
When someone says “Milky Way,” do you think of the starry pathway across our sky, or of the great pinwheel-shaped galaxy in space? Both are correct! Source: https://earthsky.org/astronomy-essentials/what-is-the-milky-way-galaxy…
Maarten Schmidt solves the puzzle of quasars
On February 5, 1963, Maarten Schmidt unraveled the mystery of quasars and pushed back the edges of the known cosmos. His insight into quasars – the most distant and luminous objects known – has changed the way scientists view the universe.

A giant black hole suddenly went dark, and no one knows why

Aliens could be sucking energy from black holes. That may be how we’ll find them.
A new study examines a potential mechanism for extracting energy from a rotating black hole, and suggests it may account for some of the energetic flares observed near these massive disruptions in time and space. Source: https://www.livescience.com/aliens-suck-black-hole-energy.html
