Splendors of the Universe on YOUR Night!

M42 The Orion Nebula

M42, the Orion Nebula is a region of star formation about 1,300 light-years away—the closest to our Solar System. It is roughly 30 light-years across, and contains enough material to make 2,000 stars the size of our sun.

M77

M77 is truly remarkable in its extremes. It is 47 million light-years away and at its greatest extent it is 170,000 light-years across (the largest galaxy on the Messier List). Its central portion (shown here) is exceedingly bright—in fact, this galaxy actually changes in brightness due to a black hole in the center.    

Satellites

Human technology! There are almost 500 of these in Low Earth Orbit (we can’t see the higher ones). We see these little “moving stars” because they reflect sunlight.

The Green Flash

What we call “The Green Flash” is not so much a flash as a flicker of green color, seen on the top of the sun as it sets (or rises). This rare event needs just the right atmospheric conditions.

NGC 7662 Blue Snowball

NGC 7662: A planetary nebula nicknamed the “Blue Snowball.” It is a round cloud thrown off by a dying star, expanded to 1.6 lightyears in diameter. The expanding hot gas would have fried any planets orbiting the star.

Neptune

Neptune, eighth planet from the Sun, is a blue “gas giant” about 4 Earth-diameters across. At least 14 moons orbit Neptune. Galileo accidentally observed Neptune in 1612 and 1613 but did not realize it differed from the stars—its true discovery would wait until 1846.

Uranus

Uranus, the seventh planet from the Sun, was discovered by Sir William Herschel in 1781. It has a dark set of rings and at least 27 moons. Uranus’s axis of rotation is almost 90 degrees from those of the other planets, as if Uranus has been tipped onto its side.

Almach (γ And)

Almach (γ Andromedae) appears as a golden and blue double star in small telescopes. The blue star itself is actually three stars, too close together to see as individuals, making Almach a four-star system. It is about 350 light-years away, and orbits with a period of several thousand years.
