Star-mass ratio
(Preview)
Star-birth myth 'busted' An international team of researchers has debunked one of astronomy's long held beliefs about how stars are formed, using a set of galaxies found with CSIROs Parkes radio telescope. When a cloud of interstellar gas collapses to form stars, the stars range from massive to mi...

Failed supernovae
(Preview)
Netting new physics from a stellar collapse Failed supernovae could provide a strong flux of neutrinos near the detection limit of current observatories Stars more than eight times the mass of our Sun eventually collapse under their own weight, and may explode into spectacular supernovae. The te...

Largest Exoplanets
(Preview)
Lines blur between planet and full-blown star Pluto huggers and haters may hog the spotlight, but there's another debate on the bigger end of the planetary scale. Astronomers have in recent years uncovered super-massive objects that blur the boundary between planet and full-blown star. The comp...

Astronomical Lidar for Extinction
(Preview)
Helping Astronomers Collect More Accurate Images of the Sky The brightness of stars and galaxies seen through a telescope can vary from day to day because of atmospheric variability. The sky's inconsistency is due to the presence of atmospheric aerosols -- seen as haze -- that scatter and absorb so...

Distant supernova
(Preview)
Astronomers say they had found the farthest supernova ever detected, a giant star that ripped apart around 11 billion years ago. A new technique enabled the cosmologists to make the find, which should help advance knowledge into these rare phenomena and their role in generating other stars, they s...
