Gamma Ray Burst


When a massive star collapses to form a black hole, a burst of gamma rays results as particles are blasted outward at nearly the speed of light. This animation shows the most common type of gamma-ray burst. An end-on view of a jet greatly boosts its apparent brightness. One especially bright burst (GRB 130427A) was detected in 2013 by the Fermi and Swift satellites. A Fermi image of that burst ends the animation sequence.

Rotating a Galaxy


This animation illustrates the rotation rate of the Large Magellanic Cloud (LMC). Hubble Space Telescope observations have been used to determine that the central part of the LMC completes a rotation every 250 million years. It takes more than 10 million years for even the small amount of rotation illustrated in this video.

LL Orionis


This photograph is part of a large mosaic view of the complex stellar nursery in the Orion Nebula. The young variable star LL Orionis produces a stellar wind more energetic than the wind from our own middle-aged Sun. As its fast stellar wind smacks into slow moving gas, a shock front is formed, just like the bow wave of a boat moving through water or a plane traveling at supersonic speed. The small, arcing, graceful structure just above and left of center is LL Ori’s cosmic bow shock. It’s about half a light-year across.

Enceladus, Pandora, and Rings (Oh, My!)


Saturn’s moon Enceladus is backlit by the Sun in this Cassini spacecraft image from 2009. The dramatic lighting shows of the plumes that continuously spew into space from the south pole of 500 km diameter moon. The icy plumes are likely fed by an ocean beneath the ice shell of Enceladus. They supply material directly to Saturn’s outer, tenuous E ring and make the surface of Enceladus as reflective as snow. Behind Enceladus, Saturn’s rings scatter sunlight toward Cassini. Beyond the rings, the night side of the 80 km diameter moon Pandora is faintly lit by light reflecting off of Saturn.

Team Kimberlin Post of the Day


Bill Schmalfeldt has a knack for sticking his nose into other peoples’ business and then wondering why his nose got bloodied. Often, he winds up punching himself in the snout. Four years ago last week, the Cabin Boy™ sent a letter to the judge presiding over the Kimberlin v. The Universe, et al. RICO Madness LOLsuit complaining about truthful statements made concerning him in rebuttal to false statements made in court papers by Brett Kimberlin. Even if the form of his communication with the court had been proper, his letter was essentially worthless for Kimberlin’s case. Most of Schmalfeldt’s statements fit the characterization used by Magistrate Judge West in dismiss LOLsuit VIII: He “provides no proof other than his own self-serving statements[.]” Indeed, one of the few things he stated for which there might be some objective evidence is this statement about his health: “There are other outward and not-so-quite-visible signs of increased degeneration, including the onset of early Parkinson’s disease dementia.”

I published this comment In Re Docket Item 63 four years ago today.

Some things are so ludicrous and immaterial as to not be worth a reply.
