Hey y'all. Well I got me a new telescope almost 2 months ago and have been enjoying what I've seen so far and can't wait to upgrade. I was wondering if anyone knows when Jupiter will re-appear in the night sky is it always the same in the summer or seeing as our orbits are different does it change.<br /><br />also in an off topic question i would like to know if using a reflector scope can you see anything through our atmosphere during the day besides our friend Mr. Sun?

The time of year when we can see Jupiter changes as it makes it's 12 year orbit around the sun. For example if it's visible now in the summer, in 6 years it will be visible in the winter.<br /><br />Jupiter will start rising just before the sun, in the early morning hours in a few weeks, after it passes by the sun in the sky.<br /><br />It reaches opposition (when it is highest in the sky at midnight) on July 9th, and will be visible in the evening through the end of next year.<br /><br />We can't see it right now because it's too close to the sun, but the SOHO spacecraft can see it.<br /><br />If you look at this image , Jupiter is the bright dot to the left of the sun; it's moving from left to right.<br /><br />BTW, Mercury is the bright dot below the sun.<br /><br />Wayne <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Nice picture!<br /><br />To answer the second question, the only objects you can reach with a telescope by day are: Sun, Moon (visible naked eye), Venus and Mercure.<br />But the Sun's light is so bright you'll not be able to reach much details, even on the moon.<br />So the only way to make astronomy by day is either:<br />- buy a good solar filter and enjoy;<br />- fly to the moon were you won't have any problem to reach any star even by day <img src="/images/icons/smile.gif" />

I'd suspect that you can also see Jupiter, when it's far from the sun with a scope as well, and it would be far safer than Mercury <img src="/images/icons/cool.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Yeah, you're right, I didn't think of this one <img src="/images/icons/smile.gif" />.<br /><br />Probably every star or planet brighter than magnitude 1 would be theorically reachable by telescope, but I don't really see the interest of it <img src="/images/icons/smile.gif" /><br /><br />And why I put Venus and Mercure is also because sometimes they transit in front of the sun <img src="/images/icons/smile.gif" />
