The Iris Nebula is a reflection nebula 1,300 light years away, illuminated by a partially embedded star (SAO 19158) which is 10X the size of our Sun. The region is 6 light years across in total. Iris Nebula / Caldwell 4 You can really see how the light from the central cluster illuminates the dust... Continue Reading →
New Milky Way Project Paper Brilliantly Fuses Citizen Science and Machine Learning
A new Milky Way Project paper was published to the arXiv last week. The paper presents Brut, an algorithm trained to identify bubbles in infrared images of the Galaxy. Brut uses the catalogue of bubbles identified by more 35,000 citizen scientists from the original Milky Way Project. These bubbles are used as a training set to allow... Continue Reading →
A Brand New Milky Way Project
Just over three years the Zooniverse launched the Milky Way Project (MWP), my first citizen science project. I have been leading the development and science of the MWP ever since. 50,000 volunteers have taken part from all over the world, and they've helped us do real science, including creating astronomy's largest catalogue of infrared bubbles - which...

The Large Magellanic Cloud is a dwarf galaxy orbiting around our own Milky Way. You can see it from the Southern Hemisphere but not like this! This image combines Spitzer and Herschel data to show up some of this object's amazing star formation activity. Just wonderful! [via Large Magellanic Cloud | Herschel Space Observatory]
