If it is D metres from Twinky, r metres in diameter, and absorbs 80% of the light that falls on it, it will receive power given by P = (80% x (r2 Lsun)/(4(D2) It will radiate a power (from the Stefan Boltzman equation) of P = 80% x 4(r2 (T4 Equating the two, and solving for T, we find that the temperature at present is around 220K (-53o Celsius). ...

. ATLAS is a project to image seven square degrees of sky, in two fields (CDF-S and ELAIS-S1), at radio wavelengths, to an rms of about 15 Jy, making it the widest deep radio survey aver attempted. The fields are chosen to cover the Spitzer Wide-Area IR Extragalactic Survey (SWIRE), and the radio images cut through the dust, to trace the cosmic history of AGN and star-forming galaxies.
