Astronomers observe distant galaxy powered by primordial cosmic fuel

more »

(Phys.org) —Astronomers have detected cold streams of primordial hydrogen, vestigial matter left over from the Big Bang, fueling a distant star-forming galaxy in the early Universe. Profuse flows of gas onto galaxies are believed to be crucial for explaining an era 10 billion years ago, when galaxies were copiously forming stars. To make this discovery, the astronomers – led by Neil Crighton of the Max Planck Institute for Astronomy and Swinburne University – made use of a cosmic coincidence: a bright, distant quasar acting as a "cosmic lighthouse" illuminates the gas flow from behind. The results were published October 2 in the Astrophysical Journal Letters.

Herschel throws new light on oldest cosmic light

more »

(Phys.org) —Cosmologists have achieved a first detection of a long-sought component in the Cosmic Microwave Background (CMB). This component, known as B-mode polarisation, is caused by gravitational lensing, the bending of light by massive structures as it travels across the Universe. The result is based on the combination of data from the South Pole Telescope and ESA's Herschel Space Observatory. This detection is a milestone along the way to the possible discovery of another kind of B-mode signal in the polarised CMB - a signal produced by gravitational waves less than a second after the Universe began.

Star Cluster Pismis 24, core of NGC 6357 Sticker

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

Star Cluster Pismis 24, core of NGC 6357 Sticker

tagged with: stars, galaxies, astronomy, envelope sealers, 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.

This Hubble photograph of the Orion Nebula is a great choice for astronomy lovers!

This is a photograph of the massive Orion Nebula, taken by the Hubble Space Telescope. The Orion Nebula is the birthplace of many new stars, and over 3000 stars are present in this image, surrounded by swirling clouds of gas and dust. The colours of the original photo have been enhanced slightly, and include rich oranges, pinks and purples.
