Now through spring, the sky will offer a number of don’t-miss celestial events, and Long Island has ideal places to view them.

The Vanderbilt Museum and Planetarium in Centerport recently acquired a solar telescope, and a new observatory opened in Montauk, where light pollution is less intrusive than in more populated areas.

“You can see all these different things going on,” says Patrick Keefe, director of communications at Vanderbilt. “Flares leaping off the sun, spots. . . . Staring at something 93 million miles away is jaw-dropping.”

At the Montauk observatory, executive director Donna McCormick says, “We have a large lecture space and will be offering regular programs.” The best places on the Island to learn about and observe the night sky:

PLANETS IN OPPOSITION are times when a planet will have its closest approach to Earth: Oct. 15 Uranus; April 7 Jupiter

PLANETS IN GREATEST EASTERN ELONGATION are when a planet will be at its highest point above the horizon and easily visible: Dec. 11 Mercury; Jan. 11 Venus; April 1 Mercury

SUPERMOON is when this celestial body will be closest to Earth: Oct. 16; Nov. 14; Dec. 14

MAJOR METEOR SHOWERS are the events most people have observed. All you need is darkness and an open sky: Oct. 20, 21 Orionids; Dec. 13, 14 Geminids; Jan. 3, 4 Quadrantids; April 22, 23 Lyrids; May 6, 7 Eta Aquarids

PENUMBRAL LUNAR ECLIPSE coming Feb. 10, 11. This can be a bit hard to see as the Earth’s shadow (umbra) misses the moon.
