Major supercluster of galaxies found hidden by the Milky Way

17 November 2016 Astronomy Now

An international team of astronomers has discovered a previously unknown major concentration of galaxies in the constellation Vela, which they have dubbed the Vela supercluster. The gravitational attraction from this large mass concentration in our cosmic neighbourhood may have an important effect on the motion of our Local Group of galaxies.

Find the Andromeda Galaxy in the late summer sky

2 September 2016 Ade Ashford

One of best deep-sky objects of the approaching season is the Andromeda Galaxy, or Messier 31, that is now accessible low in the east-northeast by 10pm local time in the UK and Western Europe. Here’s our comprehensive guide to locating this iconic Local Group galaxy.

Hubble sees the shredded remains of a supernova

25 July 2016 Astronomy Now

This NASA/ESA Hubble Space Telescope image captures the remnants of a long-dead star. These rippling wisps of ionised gas, named DEM L316A, are the remains of an especially energetic Type Ia supernova located some 160,000 light-years away within one of the Milky Way’s closest galactic neighbours — the Large Magellanic Cloud (LMC).

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?

Gazing into the furnace: VST captures the Fornax Cluster

13 April 2016 Astronomy Now

This new image from the VLT Survey Telescope (VST) at ESO’s Paranal Observatory in Chile captures a spectacular concentration of galaxies known as the Fornax Cluster, which can be found in the Southern Hemisphere constellation of Fornax (The Furnace). The cluster plays host to a menagerie of galaxies of all shapes and sizes, some of which are hiding secrets.

Hubble sees distant spirals through a diffuse dwarf galaxy

11 April 2016 Astronomy Now

At first glance this NASA/ESA Hubble Space Telescope image seems to show an array of different cosmic objects, but the speckling of stars shown here actually forms a single body — a nearby dwarf galaxy known as Leo A. Its few million stars are so sparsely distributed that some distant background galaxies are visible through it.

The wilds of the Local Group

23 March 2016 Astronomy Now

This image shows a lonely galaxy known as Wolf-Lundmark-Melotte, or WLM for short. Although considered part of our Local Group of dozens of galaxies, WLM stands alone at the group’s outer edges as one of its most remote members. In fact, WLM is so small and secluded that it may never have interacted with any other galaxy in the history of the universe.
