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 history of our galaxy.
Black holes:

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 distant and faint that they evade being observed. But looking at the combined light from thousands of galaxies, a team of astronomers including the University of Copenhagen showed that black holes helped turn off star formation.
GALAXIES:

Black holes helped quenching star formation in the early Universe

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, including the formation of black holes, supernovae and why galaxies die.
ASTROPHYSICS:

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

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 search for extraterrestrial life forms.
