Hubble’s fireball

17 August 2016 Astronomy Now

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.

The realm of buried giants

2 March 2016 Astronomy Now

In this huge image of part of the southern constellation of Norma, wisps of crimson gas are illuminated by rare, massive stars that have only recently ignited and are still buried deep in thick dust clouds. The vast nebula where these giants were born, known as RCW 106, is captured here in fine detail by ESO’s VLT Survey Telescope (VST), at the Paranal Observatory in Chile.

Hubble’s blue bubble in Carina

22 February 2016 Astronomy Now

At the centre of this beautiful NASA/ESA Hubble Space Telescope image is a Wolf–Rayet star known as WR 31a, located about 30,000 light-years away in the southern constellation of Carina. The distinctive blue bubble is a Wolf–Rayet nebula — an interstellar cloud of dust, hydrogen, helium and other gases expanding at a rate of around 137,000 miles per hour.

Hubble sees a cosmic couple

22 August 2015 Astronomy Now

Here we see the spectacular cosmic pairing of the star Hen 2-427 — more commonly known as WR 124 — and the nebula M1-67 which surrounds it. Both objects, captured here by the NASA/ESA Hubble Space Telescope are found in the constellation of Sagittarius and lie 15,000 light-years away.


The tell-tale signs of a galactic merger

29 January 2015 Astronomy Now

NGC 7714 is a spiral galaxy in the constellation Pisces that drifted too close to its companion. The gravitational interaction has twisted its spiral arms out of shape, dragged streams of material out into space, and triggered bright bursts of star formation.
