Ahn et al found two ultra-compact dwarf galaxies, VUCD3 and M59cO, with supermassive black holes. The findings suggest that these dwarf galaxies are likely tiny leftovers of larger galaxies that were stripped of their outer layers after colliding into other, larger galaxies Messier 87 and Messier 59, respectively.

Stellar explosions are often associated with supernovae, the powerful and catastrophic deaths of stars. But new ALMA observations of the Orion Nebula complex provide insights into explosions at the other end of the stellar life cycle -- star birth. The colors in the ALMA data represent the relative Doppler shifting of the millimeter-wavelength light emitted by carbon monoxide gas. The blue color represents gas approaching at the highest speeds; the red color is from gas moving toward us more slowly. The background image includes optical and near-infrared imaging from both the Gemini South and ESO’s Very Large Telescope. The famous Trapezium Cluster of hot young stars appears towards the bottom of this image. Image credit: ALMA / ESO / NAOJ / NRAO / J. Bally / H. Drass et al.

This is an artist impression of a progenitor of Milky Way-like galaxies in the early Universe with a background quasar shining through a ‘super halo’ of hydrogen gas surrounding the galaxy. New ALMA observations of two such galaxies reveal that these vast halos extend well beyond the galaxies’ dusty, star-forming disks. Image credit: A. Angelich / NRAO / AUI / NSF.

This Hubble image shows the supernova remnant N103B (top of the image). N103B was a Type Ia supernova, located in the Large Magellanic Cloud. Owing to its relative proximity to Earth, astronomers observe the remnant to search for a potential stellar survivor of the explosion. The orange-red filaments visible in the image show the shock fronts of the supernova explosion. These filaments allow astronomers to calculate the original centre of the explosion. The filaments also show that the explosion is no longer expanding as a sphere, but is elliptical in shape. Astronomers assume that part of material ejected by the explosion hit a denser cloud of interstellar material, which slowed its speed. The shell of expanding material being open to one side supports this idea. The gas in the lower half of the image and the dense concentration of stars in the lower left are the outskirts of the rich star cluster NGC 1850. Image credit: NASA / ESA / Hubble.
