Astrophysicists have taken a major step forward in understanding how supermassive black holes formed. Using data from three of NASA’s space telescopes, Italian researchers have found the best evidence to date that the direct collapse of a gas cloud produced supermassive black holes in the early universe.
A strange new kind of galactic beast has been spotted in the cosmic wilderness. Dubbed “super spirals,” these unprecedented galaxies dwarf our own spiral galaxy, the Milky Way, and compete in size and brightness with the largest galaxies in the universe. The galaxies have long hidden in plain sight by mimicking the appearance of typical spirals.
By pushing the NASA/ESA Hubble Space Telescope to its limits, astronomers have shattered the cosmic distance record by measuring the distance to the most remote galaxy ever seen in the universe. The galaxy, named GN-z11, has a redshift of 11.1, which corresponds to 400 million years after the Big Bang when the universe was only three percent of its current age.
A spectacular new image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope in Chile has mapped the full area of the galactic plane visible from the Southern Hemisphere for the first time at submillimetre wavelengths — between infrared light and radio waves.
