New research eclipses existing theories on moon formation

August 29, 2012 3:28 pm | by EurekAlert! | News | Comments

The Moon is believed to have formed from a collision, 4.5 billion years ago, between Earth and an impactor the size of Mars, known as "Theia." Over the past decades scientists have simulated this process and reproduced many of the properties of the Earth-Moon system; however, these simulations have also given rise to a problem known as the Lunar Paradox...

Space-warping white dwarfs produce gravitational waves

August 28, 2012 3:01 pm | by EurekAlert! | News | Comments

Gravitational waves, much like the recently discovered Higgs boson, are notoriously difficult to observe. Scientists first detected these ripples in the fabric of space-time indirectly, using radio signals from a pulsar-neutron star binary system. The find, which required exquisitely accurate timing of the radio signals, garnered its discoverers a Nobel Prize.

Supernovae of the same brightness, cut from vastly different cosmic cloth

August 24, 2012 10:26 am | by EurekAlert! | News | Comments

Exploding stars called Type 1a supernova are ideal for measuring cosmic distance because they are bright enough to spot across the Universe and have relatively the same luminosity everywhere. Although astronomers have many theories about the kinds of star systems involved in these explosions (or progenitor systems), no one has ever directly observed one—until now.
