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.
Astronomers have uncovered a unique process for how the universe’s largest elliptical galaxies continue making stars long after their peak years of star birth. NASA’s Hubble Space Telescope revealed brilliant knots and chains of hot, blue stars forming along the jets of active black holes found in the centres of giant elliptical galaxies.
MACS J0717, some 5.4 billion light-years away from Earth in the constellation of Auriga (The Charioteer), is the result of four galaxy clusters colliding. This image is a combination of observations in visible light, X-rays and radio waves from the NASA/ESA Hubble Space Telescope, NASA’s Chandra X-ray Observatory, and the NRAO Jansky Very Large Array.
Some of the Milky Way’s “celebrity stars” — opulent, attention-getting, and short-lived — can be found in this Hubble Space Telescope image of the glittering star cluster called Trumpler 14. It is only 500,000 years old, has one of the highest concentrations of massive, luminous stars in the entire Galaxy and is located 8,000 light-years away in the Carina Nebula.
