Saturn II Square The Orion molecular cloud complex

The Orion molecular cloud complex is about 1400 light-years away

Emission in this spectral line of EIT 304Å shows the upper chromosphere at a temperature of about 60

Time-sequenced images have recently shown that spicules last about five minutes

and clouds of hydrogen gas glowing in red

Saturn II Square The Orion molecular cloud complexOf the countless equinoxes Saturn has seen since the birth of the solar system, this one, captured here in a mosaic of light and dark, is the first witnessed up close by an emissary from Earth none other than our faithful robotic explorer, Cassini. Seen from our planet, the view of Saturn's rings during equinox is extremely foreshortened and limited. But in orbit around Saturn, Cassini had no such problems. From 20 degrees above the ring plane,
