NGC4631

NGC 4631 is an edge-on spiral galaxy in the constellation Canes Venatici. This galaxy’s slightly distorted wedge shape gives it the appearance of a herring or whale, which is why it is infrequently referred to as the Whale Galaxy.[3] Because this nearby galaxy is seen edge-on from Earth, professional astronomers observe this galaxy to better understand the gas and stars located outside the plane of the galaxy.

NGC 4631 contains a central starburst, which is a region of intense star formation. The strong star formation is evident in the emission from ionized hydrogen[4] and interstellar dust heated by the stars formed in the starburst.[5] The most massive stars that form in star formation regions only burn hydrogen gas through fusion for a short period of time, after which they explode as supernovae. So many supernovae have exploded in the center of NGC 4631 that they are blowing gas out of the plane of the galaxy. This superwind can be seen in X-rays[6] and in spectral line emission.[4] The gas from this superwind has produced a giant, diffuse corona of hot, X-ray emitting gas around the whole galaxy.[7]
