SMM J2135-0102
(Preview)
Intense Star-Formation within Resolved Compact Regions in a Galaxy at z=2 Scientists have found a massive galaxy in the early Universe creating stars like our Sun up to 100 times faster than the modern-day Milky Way. The team of international researchers, led by Durham University scientist and Ro...

Willman 1
(Preview)
Willman 1 or SDSS J1049+5103 is an extreme globular cluster or ultra low-mass dwarf galaxy. It is named after Beth Willman of New York University, the lead author of a study based on the Sloan Digital Sky Survey data. As of 2006, it is the third dimmest galaxy known, after Boo dSph and UMa dSph, 200 tim...

Super Supernova: White Dwarf Star System Exceeds Mass Limit An international team led by Yale University has, for the first time, measured the mass of a type of supernova thought to belong to a unique subclass and confirmed that it surpasses what was believed to be an upper mass limit. Their findings...

Title: SN 2008fv: the third type Ia supernova in NGC 3147 Authors: D. Yu. Tsvetkov, L. Elenin Multiple outbursts of type Ia SNe in one galaxy present a unique opportunity to study the homogeneity of these objects. NGC 3147 is only the second known galaxy with three SNe Ia, another one is NGC 1316. We pre...

ESO 306-17
(Preview)
The latest Hubble image showcases ESO 306-17, a large elliptical galaxy that belongs to one such "fossil group" (the term astronomers use to refer to loner galaxies). The name arises because scientists aren't sure if these galaxies really are fossils and represent the remnants of a onc...
