ALMA Goes Fossil Hunting With Hubble, Discovers Gassy Past

Back in 2004 the Hubble Ultra Deep Field (UDF) images blew our minds. 10,000 galaxies visible in an otherwise empty region of sky 1/10th the diameter of the full moon. How’s that? If every fly-speck of sky is similarly jammed with stellar pinwheels, there must be billions of galaxies above us. And there are! These spectacular…

Every year, to commemorate this happy day in space history, Hubble takes time to capture a spectacular view of a special astronomical object. This anniversary, astronomers operating the Hubble chose the Bubble Nebula, a cloud…

Empty Sky? Not To Hubble’s Eye

It works like this: while Hubble keeps one eye  (camera) on a distant galaxy cluster, it aims another at an adjacent but empty field…
