August hosts a total solar eclipse crossing the United States. This is a rare event, and totality is awe-inspiring. Solar eclipses happen at most twice yearly. The moon’s shadow casts a line across the Earth. There are three types of solar eclipses: total, partial and annular. A total eclipse occurs when the moon passes in front of the sun and completely covers it. A partial eclipse is more common and is when the moon misses the sun slightly and covers part of the sun. The third type is when the alignment is for a total eclipse but the moon appears smaller than the sun; there is a ring of sun around the moon. This is an annular eclipse.

Come to the Insperity Observatory for public night and pick up a pair of eclipse sunglasses. We are open the first Friday night of each month from sunset to 10 p.m.  Visit




Before you go …

… we’ve got a small favor to ask. More people are reading The Tribune than ever. Advertising revenues across the media  spectrum are falling fast. And unlike many news organizations, we haven’t put up a paywall – we want to keep our journalism as open as we can. So you can see why we need to ask for your help. The Tribune's independent, investigative journalism takes a lot of time, money and hard work to produce. But we do it because we believe our perspective matters – because it might well be your perspective, too. If everyone who reads our reporting, who likes it, helps to support it, our future would be much more secure. Support the only locally owned, locally produced news product in the Lake Houston area.  And thank you!
