The Hubble eXtreme Deep Field (XDF) is an image of a small part of space in the center of the Hubble Ultra Deep Field within the constellation Fornax, showing the deepest optical view in space. Released on September 25, 2012, it took 10 years to compile the images and shows galaxies from 13.2 billion years ago. The exposure time was two million seconds, or approximately 23 days. The faintest galaxies are one ten-billionth the brightness of what the human eye can see. The red galaxies are the remnants of galaxies after major collisions during their elderly years. Many of the smaller galaxies are very young galaxies that eventually became the major galaxies, like the Milky Way and other galaxies in our galactic neighborhood. The Hubble eXtreme Deep Field, or XDF, adds another 5,500 galaxies to Hubble's 2003 and 2004 view into a tiny patch of the farthest universe.

Watching lava fight with snow in Kamchatka

Science Focus

original post »

Depending on the context, volcanic eruptions are either terrifying or transfixing—sometimes both, but rarely neither. The opportunity to safely view the otherworldly spectacle of lava rarely fails to ignite a child-like, giddy wonder. The damage currently being done by a lava flows in the Cape Verde Islands, on the other hand, is heart-breaking.

We study these things because they are both lovely and terrible. We want to see a lava flow spill across a snowfield out of curiosity, and we want to better understand the hazards surrounding snow-capped volcanoes out of caution. Benjamin Edwards of Dickinson College and Alexander Belousov and Marina Belousova of Russia’s Institute of Volcanology and Seismology got the opportunity to witness one of these events last year in Russia’s Kamchatka Peninsula. For nine months, Tolbachik spewed basaltic lava flows that ultimately covered 40 square kilometers, reaching as far as 17 kilometers from their source.

The lava flows came in two flavors, known to geologists by Hawaiian names. (While frozen Kamchatka doesn’t exactly evoke coconuts and grass skirts, these lavas are similar to those of the Hawaiian volcanoes.) First there’s ʻaʻa (pronounced as a staccato “AH-ah”), which ends up a chunky, blocky crumble of basalt. The other is pahoehoe (roughly “puh-HOY-hoy”, which is how volcanologists answer the phone), which flows more like thick batter and can solidify into a surface resembling a pile of ropes.

Large Magellanic Cloud Superbubble in Nebula N44 Sticker

tagged with: envelope sealers, awesome astronomy images, interstellar hydrogen clouds, sbsblmc, star cluster ngc 1929, supernovas, new born stars, n44 nebula, dust clouds, hot young stars, star nursery

Galaxies, Stars and Nebulae series An awesome photograph from deep space featuring a super bubble in the Large Magellanic Cloud, which is a small satellite of our Milky Way galaxy around 160000 light years from us.
The massive stars of this nebula produce intense radiation, expelling matter at high speeds, and race through their main stage finally to explode as supernovas. The stellar winds of charged hydrogen and other particles and the supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. Blue shows hot regions created by these winds and shocks, while red shows where the dust and cooler gas are found. Yellow regions show where ultraviolet radiation from hot, young stars is causing gas in the nebula to glow.

The Carina Nebula (also known as the Great Nebula in Carina, the Eta Carina Nebula, or NGC 3372) is a large bright nebula that surrounds several open clusters of stars. Eta Carinae and HD 93129A, two of the most massive and luminous stars in our Milky Way galaxy, are among them. The nebula lies at an estimated distance between 6,500 and 10,000 light years from Earth. It appears in the constellation of Carina, and is located in the Carina–Sagittarius Arm. The nebula contains multiple O-type stars.
