A radio and optical view of galaxy NGC 5643 shows the fiery core of a luminous Seyfert galaxy, powered by gas and debris being sucked into a supermassive black hole hidden by vast clouds of dust and debris. It is difficult to probe the shrouded inner regions of a Seyfert galaxy, but researchers using the Atacama Large Millimetre/submillimetre Array – ALMA – and the Multi Unit Spectroscopic Explorer – MUSE – on the Very Large Telescope have captured this view of electrically charged gas being ejected from the black hole’s accretion disk to either side of the core. Cold molecular gas traced by carbon monoxide, seen in red, defines the galaxy’s rotating inner region.
The NASA/ESA Hubble Space Telescope has detected superhot blobs of gas, each twice as massive as the planet Mars, being ejected near a dying red giant star in the V Hydrae binary system. The plasma balls are zooming so fast through space it would take only 30 minutes for them to travel from Earth to the Moon.
To better understand how planets in binary star systems form and evolve, astronomers using the Atacama Large Millimetre/submillimetre Array (ALMA) took a new, detailed look at the planet-forming disc around HD 142527, a binary star about 450 light-years from Earth in a cluster of young stars known as the Scorpius-Centaurus Association.
