The Pleiades (Messier 45), in Taurus, are an impressive sight with any or no optical aid. Akira Fujii By: Kelly Beatty, Sky & Telescope, August 28, 2014 A new measurement, made using radio interferometry, argues that the distance to the Pleiades star cluster measured by ESA’s Hipparcos satellite is decidedly wrong — and that …
“ The RadioAstron telescope’s resolution is so good, it could pick out a snooker ball on the moon” If you thought black holes were strange, try a white one. Katia Moskvitch joins the hunt Thar she blows PHYSICS is full of opposites. For every action, there’s a reaction; every positive charge has …

VST snaps a very detailed view of the Pinwheel Galaxy The new picture is among the most detailed wide-field views of this object ever taken and shows the many glowing red gas clouds in the spiral arms with particular clarity. The VLT Survey Telescope (VST) at the European Southern Observatory’s (ESO) Paranal Observatory in Chile …
An artist’s conception of a gamma-ray burst. European Southern Observatory Astronomers might be on the brink of developing a new rung on the cosmic distance ladder. Astronomy is a discipline pursued at unimaginable distances. And yet actually measuring the distance to a nearby exoplanet, or to a galaxy shining at us from the dark depths …
Astronomers using NASA’s Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record-holder by 200 million years. These “lensing” galaxies are so massive that their gravity bends, magnifies, and distorts light …
