Any chance of snapping pics of the solar eclipse on Wednesday?
tortoise said:Fantastic! Thank you.
I have a question.
How powerful a telescope do you need to see planets as "planets"? As in, often you can clearly see Venus or Mars as very bright lights in the night sky, but through the small 'scopes I had as a kid they just looked like bigger bright lights.
At what power are they viewable as something like the moon looks to us?
Larry B. said:The eclipse will be seen in Africa. By the way the eclipse lasts about 2 min and then if the weather is cloudy you miss it. Now the astronomers can make an eclipse in the lab anytime they want to with special scopes. They can observe the corona when ever they feel like it.
Larry B. said:Here is a little info on our Sun. It is almost 900,000 miles in diameter compared to the Earths 8,000. It is half way through it life and will last another 5 billion yrs. After that it will swell to a red giant and will be as large as the orbit of Earth. It will incinerate Mercury, Venus and the Earth. It get 10% bigger every billion yrs. In a few hundred million yrs it will be too hot on Earth for any life. All the oceans will already have evaporated. So I suggest you get you affairs in order.
