What are Magellanic Clouds?

8 Nov , 2016 by Matt Williams

Beyond the Milky Way Galaxy lies the Small and Large Magellanic Clouds, two bundles of stars and dust that orbit our galaxy at a distance of 160,000 and 200,000 light years.

Gamma Ray Bursts Limit The Habitability of Certain Galaxies, Says Study

11 Dec , 2014 by Vanessa Janek

Gamma ray bursts (GRBs) are some of the brightest, most dramatic events in the Universe. These cosmic tempests are characterized by a spectacular explosion of photons with energies 1,000,000 times greater than the most energetic light our eyes can detect. Due to their explosive power, long-lasting GRBs are predicted to have catastrophic consequences for life […]

Viewed from above, we can now see that our gaze takes across the Perseus Arm (toward the constellation Cygnus), parts of the Sagittarius and Scutum-Centaurus arms (toward the constellations Scutum, Sagittarius and Ophiuchus) and across the central bar. Interstellar dust obscures much of the center of the galaxy. Credit: NASA et. all with additions by the author.

10 Interesting Facts About the Milky Way

3 Dec , 2014 by Matt Williams

The Milky Way Galaxy is an immense and very interesting place. Not only does it measure some 120,000–180,000 light-years in diameter, it is home to planet Earth, the birthplace of humanity. Our Solar System resides roughly 27,000 light-years away from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas […]

Whittling Away At SN1987A

15 Nov , 2014 by Tammy Plotner

A team of Australian astronomers has been busy utilizing some of the world’s leading radio telescopes located in both Australia and Chile to carve away at the layered remains of a relatively new supernova. Designated as SN1987A, the 28 year-old stellar cataclysm came to Southern Hemisphere observer’s attention when it sprang into action at the […]

‘Cosmic Zombie’ Star Triggered This Explosion In Nearby Galaxy

5 Jun , 2014 by Elizabeth Howell

It might be a bad idea to get close to dead stars. Like a White Walker from Game of Thrones, this “cosmic zombie” white dwarf star was dangerous even though it was just a corpse of a star like our own. The result from this violence is still visible in the Spitzer Space Telescope picture you see above. […]
