| Jupiter's moon Ganymede may harbor 'club sandwich' of oceans and ice Posted: 01 May 2014 11:07 AM PDT The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon's makeup. |
| Nearby galaxy is a 'fossil' from the early universe Posted: 01 May 2014 10:26 AM PDT Scientists analyzed the chemical elements in the faintest known galaxy, called Segue 1, and determined that it is effectively a fossil galaxy left over from the early universe. Stars form from gas clouds and their composition mirrors the chemical composition of the galactic gas from which they were born. |
| First ever gravitationally lensed Type Ia supernovae discovered Posted: 01 May 2014 10:25 AM PDT Astronomers have discovered three distant exploding stars that have been magnified by the immense gravity of foreground galaxy clusters, which act like 'cosmic lenses.' These supernovae are the first of their type ever to be observed magnified in this way and they offer astronomers a powerful tool to check the prescription of these massive lenses. |
