Hubble sees the shredded remains of a supernova

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).

Seek out the celestial treasures within the Summer Triangle

At the beginning of August, keen observers in the heart of the UK can celebrate the return of truly dark skies around 1am BST. But the naked-eye stars are out by 11pm, and if you cast your gaze two-thirds of the way from southeast horizon to overhead at this time you can see the so-called Summer Triangle in all its glory.

X marks the spot at the centre of the Milky Way

Astronomers have uncovered the strongest evidence yet that an enormous X-shaped structure made of stars lies within the central bulge of the Milky Way. Previous computer models, observations of other galaxies, and observations of our own Galaxy have suggested that the X-shaped structure existed, but no one had observed it directly.
