Even more pretty pictures

To celebrate the Hubble Space Telescope’s twentieth year in orbit, NASA have released, through Abrams Books, Hubble: A Journey Through Space and Time. This book aims to be an authoritative account of the observatory, crammed with pictures and information.

Meanwhile, the satellites aren’t sleeping through this anniversary. The Spitzer infrared space telescope has been conducting a survey of starbirth in the region of the Orion Nebula alongside Hubble. The stunning image resulting from this can be seen here. The survey looked at changes in brightness of the young stars due to their spinning and having cooler, darker areas on their surfaces, as well as variations in brightness caused by discs and wisps of dust and gas. Spitzer also studied the emissions from dust warmed by the light of the new stars.

Finally, Discovery wants your pictures. At the moment, and until around the tenth of April, Venus and Mercury are making an appearance in the evenning skies at sun set as a pair. Discovery want your photos of this event. This, of course, assumes somewhere in the world there will be a clear sky, which from this window doesn’t seem likely any time soon… Add your pics here.
