The planet Saturn is in opposition tonight. This means that it rises just as the sun sets. Look for it in the night sky as it passes M44 (the Beehive cluster) in the Cancer group. A beautiful view of the rings and the southern hemisphere of Saturn is expected.
For those who wish to delve deeper into the sky, look up to galaxy NGC 1023 in the Perseus group. This is a beautiful example of an SB0 type spiral galaxy. Its spiral arms cannot be seen but this is not because the telescope is not powerful enough. Unlike the Milky Way, NGC 1023 has no such arms, but has a galactic navel that twists like a thick lens that escapes outward. At the center of this navel is one of the largest known black holes. There is nothing to fear from being drawn to it. This galaxy is 33 million light years away from us.
There is a supermassive black hole much closer - at the center of our galaxy. It creates a gravitational anomaly that causes the stars to enter extremely elliptical orbits at high speeds - some of them orbit the black hole in less time than it takes Jupiter to orbit the Sun. The stars belonging to the S type, appear mysteriously young. This happens because their outer atmospheres are torn apart by gravitational waves. A similar thing happens in NGC 1023, but this galaxy is at least 10 times more massive than the Milky Way.
