Messier Marathon

If you are looking for something interesting today this coming weekend why not try a Messier Marathon. A Messier marathon is an attempt, usually organized by amateur astronomers, to find as many Messier objects as possible during one night. The Messier catalogue was compiled by French astronomer Charles Messier during the late 18th century and consists of 110 relatively bright deep sky objects (galaxies, nebulae, and star clusters). For more information take a look here www.richardbell.net/marathon.html or here http://deepskymap.org/ or even here http://en.wikipedia.org/wiki/Messier_marathon.

Happy hunting!

Heavy antimatter created in gold collisions

Physicists have rooted through a morass of collisions to find the heaviest antimatter nucleus yet inside one of their particle accelerators.

Collisions between gold nuclei at the Relativistic Heavy Ion Collider (RHIC) on Long Island, New York, have yielded heavy isotopes of antihydrogen that include a subatomic particle known as an antistrange quark, which is heavier than less unusual up or down quarks.(read more)

The Many Colors of Star Birth

Source: Gemini Observatory

A dramatic image from the Gemini North telescope illustrates the dynamic and sometimes violent process of star birth. It also demonstrates the capabilities of new filters available to researchers using the Gemini Multi-Object Spectrograph (GMOS).

Known as Sharpless 2-106 (Sh2-106), the hourglass-shaped (bipolar) nebula in the new Gemini image is a stellar nursery made up of glowing gas and light-scattering dust. The material shrouds a natal high-mass star thought to be mostly responsible for the hourglass shape of the nebula due to high-speed winds (more than 200 kilometers/second) which eject material from the forming star deep within (see the recent Gemini press release on the birth of a massive star which exhibits evidence of similar processes). Research also indicates that many sub-stellar objects are forming within the cloud and may someday result in a cluster of 50 to 150 stars in this region. (read more)
