Naked Eye Orion sketched from Ireland

Recently I have spent some time in the west of Ireland . It’s been stormy , with icy rain and sideways on hailstones battering the landscape. The winds have been epic in this wild place where the ancient potato drills shout evidence of our ancestors ribs bursting the Earth , still hungry after all these years. Most evenings I have stepped outside to look up at the night sky while listening to the Atlantic roar its salty roar at stars too far away to listen. Occasionally the clarity of the sky has been impressive but short-lived. However on the evening of March 23rd on opening the door I was met with what I can only describe as a crisis sky. Every familiar constellation was buried in the galaxy. It is sometimes said that there are more stars in the night sky than grains of sand on all the worlds beaches, that sky was the epiphany of that statement. I sat … Continue reading

High-Definition Panoramic View of the Andromeda Galaxy

The largest NASA Hubble Space Telescope image ever assembled, this sweeping bird’s-eye view of a portion of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic next-door neighbor. Though the galaxy is over 2 million light-years away, the Hubble telescope is powerful enough to resolve individual stars in a 61,000-light-year-long stretch of the galaxy’s pancake-shaped disk. It’s like photographing a beach and resolving individual grains of sand. And, there are lots of stars in this sweeping view — over 100 million, with some of them in thousands of star clusters seen embedded in the disk. This ambitious photographic cartography of the Andromeda galaxy represents a new benchmark for precision studies of large spiral galaxies that dominate the universe’s population of over 100 billion galaxies. Never before have astronomers been able to see individual stars inside an external spiral galaxy over such a large contiguous area. Most of the stars in the universe live inside … Continue reading
