M82 Cigar Galaxy

M82, the “Cigar Galaxy” is an edge-on spiral galaxy, 12 million light-years away, and perhaps 37,000 light-years across. There are vast gas clouds in this galaxy, where stars are being born at an incredible rate.    

M13 Hercules Globular

M13, the “Great Globular Cluster in Hercules” was first discovered by Edmund Halley in 1714, and later catalogued by Charles Messier in 1764. It contains 300,000 stars, and is 22,000 light-years away. Light would need over a century to traverse its diameter.

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.

M57 (Ring Nebula)

M57: The Ring Nebula. This remnant of a dead star looks exactly as it’s name says – a ring or doughnut shape cloud of gas. The nebula is about 2.6 lightyears across and lies about 2,300 lightyears away.

Jupiter

Jupiter is the largest planet in the Solar System, a “gas giant” 11 Earth-diameters across. Its atmosphere contains the Great Red Spot, a long-lived storm 2-3 times the size of the Earth. The 4 large Galilean satellites and at least 63 smaller moons orbit Jupiter.

Moon

The same side of the Moon always faces Earth because the lunar periods of rotation and revolution are the same. The surface of the moon is covered with impact craters and lava-filled basins. The Moon is about a fourth of Earth’s diameter and is about 30 Earth-diameters away.

Iota (ι) Cancri

Iota (ι) Cancri is a binary star in the constellation Cancer, the crab. The brighter star is a pale yellow giant, and the fainter star is smaller and bluish-white. This pair is about 300 light-years away and the stars are almost 3000 astronomical units apart.
