Free roaming black hole detected in our galaxy for the first time

Astronomers estimate that there should be 100 million black holes roaming among the 100 billion stars in our galaxy. They are the remnants of supernova explosions that happened throughout the 10 billion years of the…

Black holes helped quenching star formation in the early Universe

While some galaxies form stars at a continuous rate, others die out and lead a more passive life. What made these galaxies stop forming stars at an early age is not well established, not the least because they are so…

New discovery about distant galaxies: Stars are heavier than we thought

A team of University of Copenhagen astrophysicists has arrived at a major result regarding star populations beyond the Milky Way. The result could change our understanding of a wide range of astronomical phenomena,…

Planets of binary stars as possible homes for alien life

Nearly half of Sun-size stars are binary. According to University of Copenhagen research, planetary systems around binary stars may be very different from those around single stars. This points to new targets in the…

Breaking news from the dawn of the universe

Gazing back to the early epochs after the Big Bang, for the first time have scientists found the ancestor of a supermassive black hole. The international research team is led by astronomers from the University of…

Hubble spots most distant single star ever seen, at a record distance of 28 billion lightyears

With a fortuitous lineup of a massive cluster of galaxies, astronomers from among other institutes the University of Copenhagen and DTU discovered a single star across most of the entire observable Universe. This is the…

New research on how to quantify quantum effects on black holes

Professor in Physics, Vitor Cardoso from the Niels Bohr Institute, NBIA, has received a DNRF Chair grant from the Danish National Research Foundation to study and quantify quantum effects on astrophysical black holes

Black Hole Billiards in the Centers of Galaxies

Researchers provide the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution, now…

New analysis leads to a fundamentally different view of supermassive black holes

In the center of most galaxies lies a supermassive black hole. Some of these are actively feeding on the gas and dust around them, expelling excess energy as powerful jets that are seen as quasars across the entire…
