Nonet1final.jpg
Nonet1final.jpgNonet (the eyes).384 viewsThe Eyes Galaxies (NGC 4435-NGC 4438, also known as Arp 120) are a pair of galaxies about 52 million light-years away in the constellation Virgo. NGC 4438 is the most curious interacting galaxy in the Virgo Cluster, due to the uncertainty surrounding the energy mechanism that heats the nuclear source; this energy mechanism may be a starburst region, or a Black Hole embedded in an active galactic nucleus (AGN). Both of the hypotheses are still being investigated.

Additionally, there is evidence to suggest that the environmental damage to the interstellar medium of NGC 4438 may have been caused by an encounter (off-center collision) with NGC 4435, millions of years ago.

I could get more detail than expected.

rosettecropfinal.jpgRosette nebula.415 viewsThe cluster and nebula lie at a distance of some 5,200 light years from Earth (although estimates of the distance vary considerably) and measure roughly 130 light years in diameter. The radiation from the young stars excite the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.

It is believed that stellar winds from a group of O and B stars are exerting pressure on interstellar clouds to cause compression, followed by star formation in the nebula. This star formation is currently still ongoing.

A survey of the nebula with the Chandra X-ray Observatory in 2001 has revealed the presence of very hot, young stars at the core of the Rosette Nebula. These stars have heated the surrounding gas to a temperature in the order of 6 million kelvins causing them to emit copious amounts of X-rays.

chickenHA.jpgChicken nebula.429 viewsIC 2944, also known as the Running Chicken Nebula or the Lambda Cen Nebula, is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star Lambda Centauri. It features Bok globules and is most likely a site of active star formation.

The Hubble Space Telescope image on the right is a close up of Bok Globules discovered in IC 2944 by South African astronomer A. David Thackeray in 1950[2]. These globules are now known as Thackeray's Globules.

Sombrerocropdone.jpgSombrero galaxy1412 viewsThe Sombrero Galaxy (also known as M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo located 28 million light years from Earth. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. The dark dust lane and the bulge give this galaxy the appearance of a sombrero. Astronomers initially thought that the halo was small and light, indicative of a spiral galaxy. But Spitzer found that halo around the Sombrero Galaxy is larger and more massive than previously thought, indicative of a giant elliptical galaxy. [5] The galaxy has an apparent magnitude of +9.0, making it easily visible with amateur telescopes. The large bulge, the central supermassive black hole, and the dust lane all attract the attention of professional astronomers.Martin
