Eagle Nebula in space Poster

Here's a great poster featuring a beautiful image from deep space

This eerie, dark structure in IC 4703 (the Eagle nebula) is a column of cool molecular hydrogen gas and dust that is an incubator for new stars. The stars are embedded inside finger-like protrusions clearly seen extending from the top of the column. Each "fingertip" is somewhat larger than our own solar system. The pillar is slowly eroding away by the ultraviolet light from nearby hot stars, a process called "photoevaporation". As it does, small globules of especially dense gas buried within the cloud are uncovered. These globules have been dubbed "EGGs" ; an acronym for "Evaporating Gaseous Globules". The shadows of the EGGs protect gas behind them, resulting in the finger-like structures at the top of the cloud.

Rosetta follows Comet 67P through closest approach to the Sun

Science Focus

original post »

Thursday, the ESA's Rosetta probe returned images from the comet it orbits during its closest approach to the Sun, or perihelion. At perihelion, Comet 67P/Churyumov–Gerasimenko is about 186 million kilometers from the Sun, or a bit outside of Earth's orbit (150 million kilometers).

With the added warming from the Sun, the comet has been experiencing higher levels of activity, with gasses escaping from its interior at higher levels, pushing dust and other material out into space. Rosetta's instruments indicate about 300 liters of water are being ejected every second, meaning the comet is losing 26 million kilograms per day during this period. Another 86 million kilograms of dust are also being lost. The activity should remain high for several weeks after perihelion.

Because of the large volumes of material jetting out of the comet, the ESA's operators have backed Rosetta off to an orbit that's over 325km from the comet's surface. But that's still close enough for some pretty spectacular images.

Merging Galaxies - The Antennae Galaxies Square Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: envelope sealer, stretch frame, awesome astronomy images, super star clusters, agmcssc, antennae galaxies, merging galaxies, star cluster formation, best hubble photos, ngc4038 ngc4039, dust clouds, new born stars

Galaxies, Stars and Nebulae series A stunning outer space picture featuring two merging galaxies, known as the Antennae Galaxies - NGC4038 and NGC4039. As these galaxies hurtle through each other, billions of new stars are forced to precipitate out of the gas and dust clouds by the bunching and heating that's caused by the massive gravitic interactions. These tend to occur in clusters, the brightest and most condensed of them being known as super star clusters.

Star Cluster Pismis 24, core of NGC 6357 Room Stickers

Here's a great wall decal featuring a beautiful image from deep space


tagged with: stars, galaxies, astronomy, wall decal, star cluster, pismis 24, sculpting ultaviolet ionisation, super massive stars, sclustpsms, nebula ngc 6357

Galaxies, Stars and Nebulae series The star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 that extends one degree on the sky in the direction of the Scorpius constellation. Part of the nebula is ionised by the youngest (bluest) heavy stars in Pismis 24. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The presence of these surrounding gas clouds makes probing into the region even harder. One of the top candidates for the title of "Milky Way stellar heavyweight champion" was, until now, Pismis 24-1, a bright young star that lies in the core of the small open star cluster Pismis 24 (the bright stars in the Hubble image) about 8,000 light-years away from Earth. Pismis 24-1 was thought to have an incredibly large mass of 200 to 300 solar masses. New NASA/ESA Hubble measurements of the star, have, however, resolved Pismis 24-1 into two separate stars, and, in doing so, have "halved" its mass to around 100 solar masses.

Carina Nebula in Argo Navis constellation Wall Decor

Here's a great wall decal featuring a beautiful image from deep space


tagged with: stars, galaxies, astronomy, wall decal, carina nebula, argos navis constellation, carina the keel, star formation, gas clouds, carnebngcttst, ngc 3372

Galaxies, Stars and Nebulae series Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology).
The original image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken in the light of ionized hydrogen. Colour information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.
