This week, we’re getting out of our comfort zone and into the bubble—the Bubble Nebula, a stellar structure where a hot, young star got a lot of gum and went a little crazy. Inside this nebula, a particular star is spewing high-speed stellar wind out into space, creating a large bubble of gas around itself. Another great shot from Hubble.
Next, let’s visit a cluster so riddled with sparkling galaxies that it’s hard to choose which one to gape at. Galaxy clusters are the most massive objects we’ve discovered in space—many are so large that they physically bend the space and light around them.
Speaking of clusters, we revisit Abel 2142, which contains hundreds of galaxies and is a whopping 6 million light years across. The Chandra X-ray Observatory recently observed that Abel 2142 and another group of galaxies are on a collision course. As these two objects interact, gases from the smaller cluster will be stripped away, leaving a tail of debris that glows in x-ray light. Space might seem calm, but somewhere out there a galaxy is blowing another astral body to bits.
