Could Echoes from Colliding Black Holes Prove Stephen Hawking’s Greatest Prediction?

In 1974 Stephen Hawking theorized that black holes are not black but slowly emit thermal radiation. Hawking’s prediction shook physics to its core because it implied that black holes cannot last forever and that they instead, over eons, evaporate into nothingness—except, however, for one small problem: there is simply no way to see such faint … Read more

Astronomers Detect Rare ‘Missing Link’ Black Hole in Our Closest Galactic Neighbor

A rare treasure that could shed light on the evolution of black holes has been discovered in the Milky Way’s closest large galactic neighbor. In a cluster of stars in the Andromeda galaxy, aka M31, astronomers studied changes in light to identify a black hole clocking in at almost 100,000 times the mass of the … Read more

Powerful, nearby black holes could help to explain universe’s origins

The Haro 11 galaxy. Like Tololo 0440-381, this nearby galaxy gives off a type of radiation that scientists think resembles the characteristics of the earliest stars in the universe. Haro 11 is about 300 million light-years away in the constellation Sculptor.  (Image credit: ESA/Hubble/ESO and NASA) Nearby galaxies and their black holes could hold the … Read more

Black holes: Scientists think they’ve spotted the mysterious birth of one

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. Daniel Perley, Reader of Astrophysics, Liverpool John Moores University Astronomers are increasingly drawing back the curtains on black holes.  In the past few years, we have finally captured actual photos of these fearsome creatures and measured the gravitational waves — … Read more

40 quintillion stellar-mass black holes are lurking in the universe, new study finds

Scientists have estimated the number of “small” black holes in the universe. And no surprise: It’s a lot. This number might seem impossible to calculate; after all, spotting black holes is not exactly the simplest task. Because they’re are as pitch-black as the space they lurk in, the light swallowing cosmic goliaths can be detected … Read more

This Adorable Jumping Spider Can’t Actually See Its Own Most Vivid Color

Jumping spiders may have exceptional eyes, but one adorable species seems to have a curious lack in the vision department. New experimental evidence suggests that a jumping spider called Saitis barbipes has no photoreceptors capable of perceiving the color red.   What makes this so strange is that S. barbipes – like many jumping spiders … Read more

Hubble telescope spots a black hole fostering baby stars in a dwarf galaxy

Black holes can not only rip stars apart, but they can also trigger star formation, as scientists have now seen in a nearby dwarf galaxy. At the centers of most, if not all, large galaxies are supermassive black holes with masses that are millions to billions of times that of Earth’s sun. For instance, at … Read more

Researchers detect 1st merger between black holes with eccentric orbits

Scientists have for the first time confirmed the merger of two highly eccentric black holes.  Egg-shaped eccentric orbits form when two black holes spiral towards each other and collide under each other’s strong gravitational influence. Therefore, highly eccentric orbits may suggest black holes repeatedly snack on other black holes in densely populated areas, like the … Read more

Black hole created star-forming gas jets in a dwarf galaxy

Black holes located in dwarf galaxies usually stop star formation, but now one has been seen seeding new stars through a huge plume of ionised gas Space 19 January 2022 By Alex Wilkins A dwarf galaxy known as Hen 2-10 NASA A black hole at the centre of a dwarf galaxy has birthed new stars … Read more
