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).

Seek out the celestial treasures within the Summer Triangle

24 July 2016 Ade Ashford

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. Here’s our guide to some of the celestial highlights therein.

Mars Express spies an ancient impact crater

24 July 2016 Astronomy Now

This striking perspective view from ESA’s Mars Express shows an unnamed but eye-catching impact crater on Mars. This region sits south-west of a dark plain named Mare Serpentis (literally ‘the sea of serpents’), which in turn is located in Noachis Terra (literally ‘the land of Noah’).

Newly discovered distant solar system objects resonate with Neptune

22 July 2016 Astronomy Now

The search for distant solar system objects has found two more small worlds far outside the orbit of Neptune, beyond the Kuiper Belt. The new objects, 2014 FZ71 and 2015 FJ345, are in resonance with Neptune’s orbit, implying that these worlds either have interacted with Neptune in the past or are continuing to do so.

Hubble looks to the Final Frontier on 50th anniversary of “Star Trek”

21 July 2016 Astronomy Now

The TV series “Star Trek” captured the public’s imagination with the signature phrase, “To boldly go where no one has gone before.” The NASA/ESA Hubble Space Telescope doesn’t “boldly go” deep into space, but it is “boldly peering” deeper into the universe than ever before to explore the warping of space and time and uncover some of the farthest objects ever seen.

Hubble makes first atmospheric study of Earth-sized exoplanets

21 July 2016 Astronomy Now

Astronomers using the NASA/ESA Hubble Space Telescope have conducted the first search for atmospheres around temperate, Earth-sized planets beyond our solar system. They found indications that increase the chances of habitability on two exoplanets known as TRAPPIST-1b and TRAPPIST-1c orbiting a red dwarf star approximately 40 light-years away.

X marks the spot at the centre of the Milky Way

20 July 2016 Astronomy Now

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.
