Astronomy: March 2018



The slow fade of radioactive elements following a supernova allows astrophysicists to study them at length.


A Yale-led research team has discovered a galaxy that contains no dark matter -- a finding that confirms the possibility of dark matter as a separate material elsewhere in the universe.


This image from Hubble has plucked out an underlying population of infant stars embedded in the nebula NGC 346 that are still forming from gravitationally collapsing gas clouds.


The universe is full of mysterious exploding phenomena that go boom in the dark.


On Nov. 11, 2014, a global network of telescopes picked up signals from 300 million light-years away that were created by a tidal disruption flare -- an explosion of electromagnetic energy that occurs when a black hole rips apart a passing star.


In the Universe, galaxies are not distributed uniformly. There are some places, known as clusters, where dozens or hundreds of galaxies are found close together.


Astronomers have put NASA's Hubble Space Telescope on an Indiana Jones-type quest to uncover an ancient "relic galaxy" in our own cosmic backyard.


Galaxies are not static islands of stars -- they are dynamic and ever-changing, constantly on the move through the darkness of the Universe.


This spectacular and unusual image shows part of the famous Orion Nebula, a star formation region lying about 1350 light-years from Earth.


The new MATISSE instrument on ESO's Very Large Telescope Interferometer (VLTI) has now successfully made its first observations at the Paranal Observatory in northern Chile.


In the 1980s, scientists started discovering a new class of extremely bright sources of X-rays in galaxies.


A research team of multiple institutes, including the National Astronomical Observatory of Japan and University of Tokyo, released an unprecedentedly wide and sharp dark matter map based on the newly obtained imaging data by Hyper Suprime-Cam on the Subaru Telescope.
