Sungazing Saturdays and Sundays

Safely look at the Sun and its features—such as sunspots and prominences—through a special set of filters on our telescope.

The Observatory is open to museum visitors every Saturday and Sunday from 1:00 to 4:00, weather permitting. Admission is included with Science Center admission.

Phone 410-545-2999 after 12:00 PM on Saturdays and Sundays to find out if the Observatory will be open that day.

Some amazing Sun facts:

• The Sun is 1.4 million kilometers (869,919 miles) wide (that's 109 Earths across!)
• The Sun contains 99.86 percent of the mass of the entire solar system.
• About 1.3 million Earths could fit inside the Sun.
• The total energy radiated by the Sun averages 383 billion trillion kilowatts, the equivalent of the energy generated by 100 billion tons of TNT exploding each and every second.
• At about 5 billion years old, the Sun is half-way through its life.
