Which one are you NOT supposed to look directly at?

[From: ] [author: ] [Date: 17-05-05] [Hit: ]
the next lunar eclipse is a partial eclipse on 7 august. the next solar eclipse is total on 21 august. im going to eastern oregon to observe it. oh, and its the partial phases of a solar eclipse that are the problem. people stare to try to see whats going on,......
quantumclaustrophobe say: A solar eclipse might damage your eyes; But, you can safely look at a lunar eclipse.

Angela D say: ???

you know wrong. the next lunar eclipse is a partial eclipse on 7 august. the next solar eclipse is total on 21 august. i'm going to eastern oregon to observe it.

oh, and it's the partial phases of a solar eclipse that are the problem. people stare to try to see what's going on, look at the sun for longer than is healthy and fry their eyes.

have you ever seen a lunar eclipse? a solar eclipse?

digquickly say: Well, ..., you should never look at a solar eclipse without proper protection. Lunar eclipses pose no problem at all.
-
Starrysky say: Since the sun is several million times brighter than the moon and is giving UV and infrared light that can damage eyes, I will let you decide.

Bernard say: Solar eclipse
You can look at a lunar eclipse quite fine, unless you're using a telescope
-
poornakumar b say: Solar. Is it necessary that a Lunar one should be unsafe too because Solar eclipse is harmful to the eye, if viewed for obvious reasons?
Lunar Eclipse is inherently safe. Only half-thinking Americans who are professional scare-mongers (& have no other work), generate such ideas.

cosmo say: The thing that is dangerous to look at is any part, no matter how small, of the solar photosphere. Part of the solar photosphere is exposed during a solar eclipse, except during the few minutes of totality.

We have evolved a pain mechanism that prevents us from looking at the Sun for more than a second, but this mechanism fails when the Sun is partly covered by the Moon (since the total brightness is less), even though
any small part of the Sun is damaging. So during the partial phases of a solar eclipse it is possible to look at the Sun without pain, even though it is doing permanent damage to your retina.

Technically speaking, it's "total brightness" that activates the pain mechanism, but it's "surface brightness" that does the eye damage. The two types of brightness differ only during a solar eclipse.

Morningfox say: If it happens after sunset, then it's a lunar eclipse. That's okay to look at, you're just looking at the moon.

If it happens during the day, then it's a solar eclipse. The moon goes in front of the sun for a few seconds or minutes. That's dangerous to look at, because the the edge of the sun can be seen around the edge of the moon.
