The Whichness of the Why
May 21, 2015 Another asteroid has been detected sporting a long tail. Comets are often called “dirty snowballs” by astronomers. However, various investigative missions, such as Giotto and Deep Impact, revealed them to be blackened, cratered, and fractured. No ice fields, reflective crust, or watery clouds were observed. Indeed, the…
Dark Light
May 20, 2015 A new supernova illustrates the same old problems. In January 2014 astronomers discovered the first type 1A supernova seen in a decade. Type 1A class stellar explosions (or, implosions) are important to how astronomers view the Universe for two reasons: their light-curves, or graphs of their…
Circular Afterglow
May 19, 2015 Some gamma ray bursts exhibit unusual characteristics. When charged particles are accelerated in an electric field, they emit synchrotron radiation that creates X-rays and gamma rays—something that has been demonstrated in laboratory experiments. Gamma rays are a class of theoretical “electromagnetic particles” called photons, which are…

Plasma Forms
May 14, 2015 Measurements indicate that this nebula is one degree above absolute zero. Temperature has little to do with electricity, though. “Bipolar outflow” is a term used to describe the nebular structure seen above, although the cause of the effect remains baffling to scientists who study such phenomena….

Close Cousins
May 12, 2015 Could Mercury and the Moon be more closely related than previously thought? On March 18, 2011 the MESSENGER spacecraft (Mercury Surface, Space Environment, Geochemistry and Ranging) entered orbit around the planet Mercury. The last time a spacecraft explored Mercury was Mariner 10 during its tour of it…
