The vast Tarantula Nebula in the Large Magellanic Cloud is the largest stellar nursery in the local universe and as such, an ideal laboratory for studying the birth and evolution of massive stars. This region on the outskirts of the Tarantula, known as LHA 120-N 150, features an exceptionally high concentration of massive suns. Theory suggests such stars should form within star clusters, but about 10 percent of those found in LHA 120-N 150 seemingly formed in isolation. Astronomers are using the Hubble Space Telescope to better understand whether the isolated stars truly formed alone or simply moved beyond the clusters in which they were born.
Cosmic mystery deepens with conflicting measurements of Hubble constant
Interacting galaxies produce eye-shaped “tsunami” of stars
Astronomers using the Atacama Large Millimetre/submillimetre Array (ALMA) have discovered a tsunami of stars and gas that is crashing midway through the disc of a spiral galaxy known as IC 2163. This colossal wave of material — which was triggered when IC 2163 recently sideswiped another spiral galaxy dubbed NGC 2207 — produced dazzling arcs of intense star formation that resemble a pair of eyelids.
