An international team of astronomers using the HAWK-I camera attached to the European Southern Observatory’s Very Large Telescope captured this stunning deep infrared view of the Orion Nebula in 2016 showing an abundance of brown dwarfs and planetary-mass objects. The famous nebula stretches 24 light years across and even though it is about 1,350 light years from Earth it is easily visible to the unaided eye as the somewhat fuzzy “star” in the middle of Orion’s sword. Amelia Bayo, co-author of a paper discussing the HAWK-I view said “understanding how many low-mass objects are found in the Orion Nebula is very important to constrain current theories of star formation. We now realise that the way these very low-mass objects form depends on their environment.”
Dark matter may be smoother than expected
Best ever image of another star’s surface and atmosphere
Using ESO’s Very Large Telescope Interferometer astronomers have constructed the most detailed image ever of a star — the red supergiant star Antares. They have also made the first map of the velocities of material in the atmosphere of a star other than the Sun, revealing unexpected turbulence in Antares’s huge extended atmosphere.
Starvation diet for supermassive black hole dims brilliant galaxy
Astronomers may have solved the mystery of the peculiar volatile behaviour of a supermassive black hole at the centre of a galaxy known as Markarian 1018 some 590 million light-years away. Combined data from NASA’s Chandra X-ray Observatory and other observatories suggest that the black hole is no longer being fed enough fuel to make its surroundings shine brightly.
