Whenever the Earth sees a solar eclipse (Aug. 21), there is also a lunar eclipse, but if the moon does not line up exactly, the eclipse will be partial or penumbral. On Aug. 7 there will be a partial lunar eclipse, but sadly it will only be visible from Earth’s eastern hemisphere. It will not be visible in America.
A total lunar eclipse is when the moon passes into Earth’s shadow and the moon turns red. We see a partial eclipse when some of the moon misses the shadow. The third type is a penumbral eclipse. This is when the moon sees part of the sun covered by the Earth. Sunlight reaches the entire moon, but it is less sunlight than usual.
To see the wonders of the night sky, come to the Insperity Observatory on public night. It is from sunset to 10 p.m. on the first Friday each month: humbleisd.net/observatory.
Since you’re here …
… 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!
