The Tellus Observatory gives visitors a view of the night sky through a 20″ telescope perfect for viewing the Moon and planets in our solar system.

The observatory also houses a seismograph used to detect earthquakes all over the world.

Tours of the observatory are available during special events, such as lectures and Family Science Nights.


Comet Lovejoy is a fairly bright comet that can be seen with the naked eye under very dark skies and with the aid of binoculars under more urban skies. The comet was discovered in August by amateur astronomer Terry Lovejoy in Australia.

This comet will pass closest to the Earth on Wednesday (January 7) at a distance of 43.6 million miles, traveling at a speed of about 80,000 miles per hour, and it should remain visible throughout the rest of January. To see it look to the south at about 10 PM. Find the bright constellation of Orion and look a little to the west of his knee, (marked by the bright star Rigel). The comet will move slowly to the northwest towards Taurus and it should brighten over the next week. Don’t worry if you miss it, this is a periodic comet so it will be back… in 8,000 years!
