Hubble views a stubborn dwarf galaxy

4 July 2016 Astronomy Now

The fuzzy collection of stars seen in this NASA/ESA Hubble Space Telescope image forms an intriguing dwarf galaxy named LEDA 677373, located about 14 million light-years away from us in the constellation Centaurus. This particular dwarf galaxy contains a plentiful reservoir of gas from which it could form stars, but it stubbornly refuses to do so. Why?

Space telescopes find “twins” of Eta Carinae in other galaxies

6 January 2016 Astronomy Now

Located about 7,500 light-years away in the southern constellation of Carina, Eta Carinae outshines our Sun by 5 million times. The binary system consists of two massive stars in a tight 5.5-year orbit, shrouded in an expanding veil of gas and dust from an enormous eruption seen in the 1840s. Now a study using archival data from NASA’s Spitzer and Hubble space telescopes has found five similar objects in other galaxies for the first time.
