The shadowy hand of Eris – On Friday night Eris was predicted to pass directly in front of a relatively faint star in the constellation of Cetus. You might think that this sort of thing happens all of the time, but you’d be wrong. Eris is so small in the sky and stars are such tiny points of light that, though they get close frequently, their actually intersections are rare. When they do intersect, though, something amazing happens: the star disappears. And since we know how fast Eris is moving across the sky, seeing how long the star disappears gives us a very precise measure of the size of Eris. Or, to be more exact, a very precise measure of a single chord passing through the body. –Mike Brown

New Supernova Lights Up Leo – A new supernova? Darn right. Lighting up Leo? Well… not without some serious visual aid, but the fact that someone out there is watching and has invited us along for the ride is mighty important. And just who might that someone be? None other than Tim Puckett. -Tammy Plotner / Universe Today

Shuttle waits out weather, technical issues – Stormy weather, a fuel leak and cracked foam thwarted NASA’s attempts to launch the shuttle Discovery this week, eventually prompting managers to push the shuttle’s final blastoff until at least Nov. 30. These views of Discovery on launch pad 39A were taken Tuesday and Thursday. –Spaceflight Now

NGC 4452

Hubble Space Telescope has imaged a striking galaxy called NGC 4452, which appears to lie exactly edge-on as seen from Earth. The result is an extraordinary picture of billions of stars observed from an unusual angle. The bright nucleus can be seen at the centre, along with the very thin disc that looks like a straight line from our unusual viewing position. To complete the picture, a hazy halo of stars on the periphery of the galaxy makes it seem to glow. - Credit: NASA/ESA HST
