- _______ Hamlet > Act III, scene II
HAMLET: Do you see yonder cloud that's almost in shape of a CAMEL?
LORD POLONIUS: By the mass, and 'tis like a CAMEL, indeed.
HAMLET: Methinks it is like a weasel.
LORD POLONIUS: It is backed like a weasel.
HAMLET: Or like a WHALE?
LORD POLONIUS: Very like a WHALE.

The most recent theory into the origins of hippopotamidae suggests that hippos and
WHALES shared a common semi-aquatic ancestor that branched off from other ARTiodactyls around 60 million years ago. This hypothesized ancestral group likely split into two branches around 54 million years ago. One branch would evolve into cetaceans, possibly beginning with the proto-WHALE Pakicetus from 52 million years ago with other early WHALE ancestors collectively known as Archaeoceti, which eventually underwent aquatic adaptation into the completely aquatic cetaceans.>>

<<NGC 4631 as seen edge-on from NASA's Chandra X-ray Observatory and Ultraviolet Imaging Telescope (UIT). The Chandra data (shown in blue and purple) provide the first unambiguous evidence for a halo of hot gas surrounding a galaxy that is very similar to our Milky Way. The orange color in the middle of the image represents ultraviolet radiation as observed by UIT, tracing massive stars in the galaxy. Scientists have debated for over 40 years whether the Milky Way has an extended corona, or halo, of hot gas.>>

<<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 and interstellar dust heated by the stars formed in the starburst. 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 and in spectral line emission. The gas from this superwind has produced a giant, diffuse corona of hot, X-ray emitting gas around the whole galaxy.>>
