A repeating Fast Radio Burst from a spiral galaxy deepens the mystery of where these signals originate from

At this point in time, one of the greatest mysteries in astronomy is where short, dramatic bursts of radio light seen across the universe, known as Fast Radio Bursts (FRBs), are originating from. Although FRBs last for only a thousandth of a second, there are now hundreds of records of these enigmatic sources. However, from … Read more

New link found between mass of Supermassive black holes and their host galaxies

A team of astronomers has discovered a novel way to “weigh” supermassive black holes at the centres of galaxies by measuring the distances between the galaxies that contain them. Mysterious, massive dark objects lurk at the centre of nearly all galaxies and can be observed with high enough sensitivity. Astronomers believe these to be black … Read more

Researchers discover that a giant smash of galaxy clusters forms bar structure in spiral galaxies

Researchers in Korea reported in 2019 June 24th issue of Nature Astronomy that a giant smash of two clusters of galaxies can form bar structure, an important structure inside many spiral galaxies. It has been known that galaxies, systems made of hundreds of billions of stars, can take many different shapes. The reason why galaxies … Read more

Galaxy clusters caught in a first kiss

For the first time, astronomers have found two giant clusters of galaxies that are just about to collide. This observation can be seen as a missing ‘piece of the puzzle’ in our understanding of the formation of structure in the Universe, since large-scale structures—such as galaxies and clusters of galaxies—are thought to grow by collisions … Read more

Star formation burst in the Milky Way 2-3 billion years ago

A team led by researchers of the Institute of Cosmos Sciences of the University of Barcelona (ICCUB, UB-IEEC) and the Besançon Astronomical Observatory have found, analysing data from the Gaia satellite, that a severe star formation burst occurred in the Milky Way about to and three thousand million years ago. In this process, more than … Read more
