It is known today that merging galaxies play a large role in their evolution, and the formation of elliptical galaxies in particular. However, there are only a few merging systems close enough to be observed in depth. The pair of interacting galaxies seen here — known as NGC 3921 — is one of these systems. But ‘close’ is a relative term: NGC 3921 lies 270 million light-years away.
“Eclipse Totality over Sassendalen” is the overall winning picture, making Luc Jamet of France the Insight Astronomy Photographer of the Year 2015. The prestigious annual competition received 2700 spectacular entries from 59 countries this year. The winning images from the 11 categories are showcased at the Royal Observatory Greenwich in an exhibition open 18 September 2015 — 26 June 2016
The Sculptor Dwarf Galaxy, pictured in this new image from ESO’s La Silla Observatory, is a close neighbour of the Milky Way. This galaxy is much smaller and older than ours, making it a valuable subject for studying both star and galaxy formation in the early universe. However, due to its faintness, studying this object is no easy task.

Galactic arms, sunflowers and whirlpools are only a few examples of nature’s apparent preference for spirals. A beautiful example is Messier 63, nicknamed the Sunflower Galaxy, its winding arms shining bright due to the presence of recently formed, blue–white giant stars and clusters, readily seen in this NASA/ESA Hubble Space Telescope image.
Nomination number 13 from the prestigious Insight Astronomy Photographer of the Year competition, an annual celebration of the most beautiful and spectacular visions of the cosmos by astrophotographers worldwide.

Portrayed in this image from ESA’s Planck satellite are the Large and Small Magellanic Clouds, dwarf galaxies that are among the nearest companions of our Milky Way. The Large Magellanic Cloud, about 160,000 light-years away, is the large red and orange blob close to the centre of the image. The Small Magellanic Cloud lies some 200,000 light-years from us.
