The aluminum-domed Crosby Observatory atop Orlando Science Center houses Florida's largest publicly accessible refractor telescope. This one-of-a-kind custom-built telescope, along with several smaller scopes, are available at selected times for solar and night sky viewing.
Peer through the powerful, 10-inch lens of the refractor telescope to view the planets, the four moons of Jupiter, the rings of Saturn and deep sky objects such as galaxies, nebulas and double stars.
All activities and events in the Crosby Observatory
are weather permitting only.
September 7, 2013 - May 3, 2014
First Saturday of every month, 3:00 - 5:00 p.m.
Safely gaze upon the closest star to our home planet - the Sun. Our astronomers take aim at the sun to reveal the secrets hidden behind its glare. Take a peek at the Sun’s surface to see what kind of day the sun is having. Sometimes the surface is placid and serene but more often than not, it is boiling with sunspots and solar flares.
November 16, 2013 - February 15, 2014
Fridays & Saturdays, First & Third Weekends of the Month, 5:00 - 9:00 p.m.
Join our astronomers in the Crosby Observatory for a night full of wonder. Enjoy views of the celestial objects while you take in the glittering Orlando skyline. Our telescopes will expand your horizons to places like Jupiter, Mars and Venus and beyond.

Discovered in 1986 by Australian astronomer Malcolm Hartley, comet 103P or Hartley 2 is set for the closest encounter with earth in 24 years. This “dirty snowball” that is comprised of rock, dust, ice and frozen gases was visible in the constellation of Auriga as a fuzzy, green blur to Northern Hemisphere observers during Mid-October.
Through November, Southern Hemisphere stargazers can catch a glimpse of the comet as it travels away from earth, using the naked eye, binoculars and of course, a telescope. This year, Hartley 2 made its closest pass at a mere 11 million miles on October 20th and is calculated to orbit the Sun every 6 ½ years. EPOXI, or Extrasolar Planet Observation and Deep Impact Extended Investigation is a spacecraft that is due to make a flyby of Hartley 2 from only 600 miles away on November 4th. The mission plans to gather information on the comet’s surface and craters, as well as close-up images of dust and gas plumes.
