Visit the Royal Observatory

Astronomy Photographer of the Year

M31, The Andromeda Galaxy

This is a single 20 minute exposure with a William Optics 80mm refractor and Canon XSi. I used Photoshop to increase the exposure 2X and levels to darken the sky. I lost some of the detail in the core, but discovered detail in the arms.

Space Daily: Closest Encounter With Jupiter Until 2022

by Dr. Tony Phillips
Huntsville AL (SPX) Sep 16, 2010
Been outside at midnight lately? There's something you really need to see. Jupiter is approaching Earth for the closest encounter between the two planets in more than a decade--and it is dazzling.
The night of closest approach is Sept. 20-21st. This is also called "the night of opposition" because Jupiter will be opposite the sun, rising at sunset and soaring overhead at midnight. Among all denizens of the midnight sky, only the Moon itself will be brighter.

Hubble Completes 100,000th Orbit, Takes Yet Another Breathtaking Photo

Hubble, without a doubt the most spectacular digital camera in the solar system, has completed its 100,000th orbit. To celebrate, scientists pointed the telescope to NGC 2074, a spectacular star birthplace 170,000 light-years away, right next to the Tarantula nebula, where Ming of Mongo is probably building a weapon of mass destruction. Like always, the image—taken with the Wide Field Planetary Camera 2—is breathtaking, especially the high resolution version:

Astronomy Photographer of the Year 2010

Congratulations to Tom Lowe who wins the title Astronomy Photographer of the Year 2010 with this spectacular image of ancient trees silhouetted against the bright star clouds of the Milky Way. Competition judge Marek Kukula says: ‘I think this beautiful picture perfectly captures the spirit of Astronomy Photographer of the Year, linking the awe-inspiring vista of the night sky with life here on Earth. The bristlecone pines in the foreground can live as long as five thousand years. But they are babies compared to the starlight shining behind them, some of which began its journey towards us almost 30,000 years ago.
