Festive nebulae light up Milky Way Galaxy satellite

23 December 2016 Stephen Clark

The sheer observing power of the Hubble Space Telescope is rarely better illustrated than in an image such as this. This glowing pink nebula, named NGC 248, is located in the Small Magellanic Cloud, just under 200,000 light-years away and yet can still be seen in great detail.

A cosmic winter wonderland

22 December 2016 Astronomy Now

Although there are no seasons in space, this cosmic vista invokes thoughts of a frosty winter landscape. It is, in fact, a region called NGC 6357 where radiation from hot, young stars is energizing the cooler gas in the cloud that surrounds them.

Crash course?

It may look as though Saturn’s moon Mimas is crashing through the rings in this image taken by NASA’s Cassini spacecraft, but Mimas is actually 45,000 kilometres (28,000 miles) away from the rings.

It’s chaos at Saturn’s moon Hyperion

5 December 2016 Astronomy Now

The moon Hyperion tumbles as it orbits Saturn. Hyperion’s spin axis has a chaotic orientation in time, meaning that it is essentially impossible to predict how the moon will be spinning in the future.

Tangled threads weave through cosmic oddity

4 December 2016 Astronomy Now

New observations from the NASA/ESA Hubble Space Telescope have revealed the intricate structure of the galaxy NGC 4696 in greater detail than ever before. The elliptical galaxy is a beautiful cosmic oddity with a bright core wrapped in system of dark, swirling, thread-like filaments.

Icy moon Mimas dwarfed by Saturn’s rings

30 November 2016 Astronomy Now

Saturn’s icy 246-mile-wide moon Mimas (near lower left) appears tiny by comparison to the planet’s rings, but scientists think the all of the small, icy particles spread over a vast area that comprise the rings are no more than a few times as massive as Mimas. The view was obtained by NASA’s Cassini spacecraft at a distance of approximately 564,000 miles from Saturn.

Hubble spotlights irregular galaxy IC 3583

28 November 2016 Astronomy Now

This NASA/ESA Hubble Space Telescope image reveals a delicate blue group of stars — actually an irregular galaxy named IC 3583 — that sits some 30 million light-years away in the constellation of Virgo. This small galaxy is thought to be gravitationally interacting with one of its neighbours, the spiral Messier 90.
