There are many opportunities to see things that we don’t understand as we peer into the night sky. Things are unidentified flying objects (UFOs) only until we know what they are. One thing you might see is a star-like object slowly moving across the sky. With no colored or blinking lights, it’s not an airplane. What could it be?

Most likely it is a satellite or spacecraft that humans have put into orbit around the Earth. Some can be quite bright. There are websites that have been set up to help you identify any satellites you see. One that many astronomers use is If you go to that website and enter the latitude and longitude of where you will be observing, it will tell you what satellites should pass through your skies.

Come see the celestial wonders at the Humble ISD Insperity Observatory on the first Friday each month from sunset to 10 p.m.:
