I'm looking at ordering Solar Eclipse Glasses online. Is there anything I need to look out for? Or any recommendations. I want something that actually works, not some super cheap ripoff that will make me go blind.

With New Horizons reaching Pluto this week, it got me thinking about the colonization of the Solar System and I started wondering about this question. Assuming it isn't blocked out by a thick atmosphere, ala Venus, how far would we have to be from the Sun to be able to stare at it without going blind or badly damaging our eyes as on Earth. Would it be safe from Pluto? Saturn? Jupiter? Ceres? Or would you have to be way out in the Oort Cloud or further?

Thanks

If a budget deal gets passed, does anyone have any idea roughly how long it would take for Kennedy Space Center and the Astronaut Hall of Fame to be reopened to tourists?

Do we have any word on the date when Atlantis is going to be available to be viewed by the public at Kennedy Space Center yet? I hear it is almost done being prepped, but I can't find anything more specific than sometime next year.

Venus as viewed from Earth. Or Earth as viewed from Venus. I've tried looking it up and I've gotten conflicting answers. Some say that Venus would be brighter because it is closer to the sun and has a higher albedo. Some say that Earth would be brighter because Earth is larger plus we can only see half of Venus at most being an interior planet while you can see a Full Earth from Venus.

Is it a case where one answer is correct using average magnitude and the other is at maximum magnitude?

Also, I wasn't able to find the apparent magnitude of Earth from Venus so if anyone has that number it would be greatly appreciated.

Why is Pluto considered to be a dwarf planet and Charon not when they both orbit a common barycenter that is outside the surface of either body?
