A blog mainly about our world and our universe and the lenses we use to uncover their mysteries: science, reason, and imagination--with random music, thoughts, and poetry thrown in as well for good measure.

Spiral… Star?This image shows the star R Sculptoris through data collected by the Atacama Large Millimeter/submillimeter Array (ALMA). The data, which appeared in the academic paper “Unexpectedly large mass loss during the thermal pulse cycle of the red giant R Sculptoris” (Nature, 2012), was the first to discover spiral structure around a red giant star.At a distance of about 1500 light years, the interesting spiral structure might be caused by an as yet unknown companion star orbiting R Sculptoris and disturbing the intervening material.It is not unusual for red giants to exhibit shell-like structures. Red giants undergo periodic (every 10,000 to 50,000 years), but short lived (maybe 200 years or so) explosive helium burning around the stellar core. A thermal pulse leads to material being blown off the surface of the star, which in turn creates a gas-dust shell.-CBImage Credit: ALMA (ESO/NAOJ/NRAO)More InformationLink to Academic Article (choose arXiv for free access/non-subscribers)

LDN 1622 The Boogie Man Nebula
Image Copyright: Yuriy Toropin
Lynds’ Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only easily seen in long telescopic exposures of the region.
LDN 1622 lies near the plane of our Milky Way Galaxy, close on the sky to Barnard’s Loop - a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion.

This was taken a week ago, but now it’s September and I’m feeling blue.

Oh I gave you a bad sense of deja vu because I’m trying to raise money to bury my father anon? Try fucking living it you evil, insensitive bastard.
