A sea of blazing stars in a galactic spiral of gas, dust and starbirth

23 March 2023 Astronomy Now

M83, also known as the Southern Pinwheel Galaxy, is one of the largest and, at a distance of about 15 million light years, one of the nearest barred spirals to the Milky Way. The “grand design” galaxy has hosted multiple supernova blasts and appears to have a double core. Discovered in February 1752 by Nicolas-Louis de Lacaille, M83 was added to Charles Messier’s catalogue in 1781. The Hubble Space Telescope captured a spectacular view of M83 in 2014. A zoomed-in view shows countless stars in the galaxy’s outskirts embedded in rich clouds of gas and dust.

A death star’s ghostly glow

28 October 2016 Astronomy Now

The eerie glow of a dead star, which exploded long ago as a supernova, reveals itself in this NASA Hubble Space Telescope image of the Crab Nebula in the constellation of Taurus. But don’t be fooled. The ghoulish-looking object still has a pulse. Buried at its centre is the star’s telltale heart — a neutron star which beats with rhythmic precision.

ESO’S VISTA telescope reveals hidden stars in Messier 78

5 October 2016 Astronomy Now

In this new image of the nebula Messier 78, young stars cast a bluish pall over their surroundings, while red fledgling stars peer out from their cocoons of cosmic dust. ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) sees near-infrared light, which passes right through dust, permitting astronomers to probe deep into the heart of the stellar environment.
