Hubble reveals NGC 362, a young globular cluster

24 October 2016 Astronomy Now

Globular clusters offer some of the most spectacular sights in the night sky. These ornate spheres contain hundreds of thousands of stars, and reside in the outskirts of galaxies. The Milky Way contains over 150 such clusters — and the example shown in this NASA/ESA Hubble Space Telescope image, named NGC 362, is one of the most unusual ones.

Hubble reveals NGC 299 within the Small Magellanic Cloud

17 October 2016 Astronomy Now

It may be famous for hosting the Small Magellanic Cloud (SMC) and 47 Tucanae, the second brightest globular cluster in the night sky, but the southern constellation of Tucana (The Toucan) also possesses a variety of unsung cosmic beauties. One such beauty is NGC 299, an open star cluster located within the SMC just under 200,000 light-years away.

Discovering the X-ray treasures in Chandra’s archives

16 October 2016 Astronomy Now

Each year, NASA’s Chandra X-ray Observatory helps celebrate American Archive Month by releasing a collection of images using X-ray data. Each of these six new images — representing just a small fraction of the treasures that reside in Chandra’s unique archive — also includes data from telescopes covering other parts of the electromagnetic spectrum, such as visible and infrared light.

Hubble sees a ‘nuclear ring’ of star formation in galactic merger

10 October 2016 Astronomy Now

While NGC 278 may look serene, it is anything but. The galaxy is currently undergoing an immense burst of star formation as revealed in this NASA/ESA Hubble Space Telescope image. However, NGC 278’s star formation is somewhat unusual: why is it only taking place within an inner ring some 6,500 light-years across and not extend to the galaxy’s outer edges?

Two tiny moons lost among the rings of Saturn

8 October 2016 Astronomy Now

Two tiny moons of Saturn, almost lost amid the planet’s enormous rings, are seen orbiting in this Cassini probe image. Pan, visible within the Encke Gap near lower-right, is in the process of overtaking the slower Atlas, visible at upper-left.

ESO’S VISTA telescope reveals hidden stars in Messier 78

5 October 2016 Astronomy Now

In this new image of the nebula Messier 78, young stars cast a bluish pall over their surroundings, while red fledgling stars peer out from their cocoons of cosmic dust. ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) sees near-infrared light, which passes right through dust, permitting astronomers to probe deep into the heart of the stellar environment.

Hubble probes the core of galaxy NGC 247

3 October 2016 Astronomy Now

NGC 247 is a relatively small spiral galaxy in the southern constellation of Cetus (The Whale), part of the Sculptor Group around 11 million light-years from us. NGC 247 displays one particularly unusual and mysterious feature — an apparent void in the usual swarm of stars and H II regions in the northern part of its disc that spans almost a third of the galaxy’s total length.

The hidden dark side of spiral galaxy NGC 24

26 September 2016 Astronomy Now

This glorious spiral galaxy is known as NGC 24, measures some 40,000 light-years across and lies about 25 million light-years away in the southern constellation of Sculptor. However, there may be more to this picture than first meets the eye: 80 percent of NGC 24’s mass is thought to be held within an invisible dark matter halo.
