At first glance, a galaxy known as NGC 2276 looks like a typical face-on spiral, albeit a bit lopsided. But as this spectacular photo from the Hubble Space Telescope shows, the gravity of a nearby galaxy is tugging on the right side of the spiral, pulling one arm away, while interactions with hot inter-galactic gas fuel rampant starburst on the left side as indicated by the bluish-pink regions. One of those regions is believed to be home for a 50,000-solar-mass black hole. NGC 2276’s appearance has earned it a place in the aptly named Atlas of Peculiar Galaxies first published by Halton Arp in 1966.
In this NASA/ESA Hubble Space Telescope image we see the central Wolf-Rayet star known as Hen 2-427 — more commonly known as WR 124 — surrounded by the nebula M1-67. Both objects are found in the constellation of Sagitta some 15,000 light-years away. The hot clumps of gas ejected by the star into space are travelling at over 150,000 kilometres per hour.
Peering deep into the heart of our home galaxy, the Milky Way, the Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Most of the stars pictured in the image are members of the Milky Way nuclear star cluster, the densest and most massive star cluster in the galaxy. Hidden in the centre is the Milky Way’s resident supermassive black hole.
