Black hole nurtures baby stars a million light years away
Black holes are famous for ripping objects apart, including stars. But now, astronomers have uncovered a black hole that may have sparked the births of stars over a mind-boggling distance, and across multiple galaxies.

Very Large Telescope observes exoplanet where it rains iron
Researchers using ESO's Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night side where it condenses into iron droplets.

Large simulation finds new origin of supermassive black holes
Computer simulations conducted by astrophysicists at Tohoku University in Japan, have revealed a new theory for the origin of supermassive black holes. In this theory, the precursors of supermassive black holes grow by swallowing up not only interstellar gas, but also smaller stars as well. This helps to explain the large number of supermassive black holes observed today.

Astronomers spot the universe’s biggest known explosion
A black hole about 390 million light-years away has caused the biggest eruption ever seen in the universe. The supermassive black hole sits at the center of a galaxy located in the Ophiuchus galaxy cluster. Its eruption was about five times greater than the last record-holder.

One of the brightest stars in our sky has been behaving very unusually. Now scientists think they know why
The recent unusual behaviour of the star Betelgeuse could finally have been explained, after new work by astronomers. The star has been dimming strangely in recent months, with scientists speculating that it could be about to explode into a supernova or was otherwise being subject to an unknown process. Now new research has shown that the most likely explanation of the dimming is large star spots on Betelgeuse's surface, which have caused it to dim.

NASA finds active galaxy far, far away that looks like a "Star Wars" TIE fighter
Scientists have spotted an active galaxy far, far away — and it looks like it could join Darth Vader's fleet. Located 500 million light-years away in the Cassiopeia constellation, Galaxy TXS 0128+554 bears a striking resemblance to the iconic aircraft from Star Wars. According to a paper published Tuesday in The Astrophysical Journal, the galaxy is active, meaning all of its stars are not capable of providing the amount of light emitted by the galaxy on their own.

Why is there a normal galaxy sitting at the edge of the Universe?
Aided by a trick of gravity, astronomers have found a normal galaxy. Big deal, right? The thing is, where they found it is not normal: The light we see from it left the galaxy 12.4 billion years ago, meaning we’re seeing it as it was when the Universe itself was only 1.4 billion years old! That’s what makes this so weird. A normal galaxy has no business being there when the cosmos was so young. But yet, there it sits.

Sun-Like Star Identified As the Potential Source of the Wow! Signal
The Big Ear Radio Telescope in Delaware, Ohio, was disassembled in 1998 having operated for over 30 years. It was replaced by a golf course. Big Ear was never the world’s biggest radio telescope, nor its most sensitive. But Big Ear nevertheless made one of the most famous observations in the history of astronomy, one that till this day has never been explained.

A rare conjunction of Jupiter and Saturn will be visible to the naked eye for the first time in 800 years
Jupiter and Saturn are due to converge in their orbits on Monday, appearing as a double planet in the night sky — the first such occurrence in almost 800 years. The two planets have been near one another throughout the year, according to Rice University astronomer Patrick Hartigan. They will reach their closest approach, passing within 0.1 degrees of each other during the winter solstice on December 21, the longest night of the year.

Could Dark Matter Stars Exist?
Most of the universe is made up of dark matter, so could it form into stars and galaxies like regular matter? #space #darkmatter #galaxies #stars
