Jupiters four Galilean satellites continue to perform mutual eclipses and occultation’s among themselves. These events will continue until Jupiter sinsl into the sunset this summer. Jupiter is at opposition in February, so observers in any given part of the world can now see lots of them while Jupiter is well up in a dark sky. Most, howveer, involve only a slight dimming of the satellites’ light however some will cause a complete ‘blinking out’ of a satellite.
I heard that Neil Armstrong had passed away on the 25th of August. My friend had sent me a text about his passing. I stopped, re-reading the message I cursed and looked up at the sky at the rising moon.
I was 16 when Neil and Buzz walked on the moon, a matter of fact they landed on the moon on my birthday . That was the nicest gift I had ever ben given. I sat in awe with the rest of the world that evening as we watched Neil slowly climb down the ladder and put the first footprints of man on the moon. ‘That’s one small step for [a] man one giant leap for mankind”.
Neil became a silent hero for the American people. He was a quite man that shied away from public life. He never made a big deal about the fact that he was the first man to walk on the moon. He would have rather been teaching and working in beloved areo-space engineering world than to do the public thing. No matter what he will always have the honor of being the first man to step from the earth to the moon.
So on a bright moonlit night lets all look up at the moon and give a wink and say a silent thank you to Neil Armstrong.
Mike, Ed, and I met at the Krispy Kreme Doughnut Shop on Hwy 280 near CR 119 the night of the Super Moon. We set up a couple of scopes, drank some really good coffee, and shared a clear – if bright – sky with about fifty or so folks throughout the evening. Mike had already set up his 8″ Celestron when I arrived at sundown. I set up the Questar 3.5, unfolder a good chair and the two of us walked in the Krispy Kreme to get our first cup of coffee for the evening.
We had a great spot. The shop is about 50 yards off of the main road and there is a sloping grassy area between the parking lot and the traffic. They have one of those 1940’s restored delivery trucks on display with the Krispy Kreme markings and we were right next to it in clear view of the people traveling up and down the main drag. It didn’t take long for folks to startwalking up and asking us if we were there for the “big moon” that had been talked about on TV for a couple of days.We told them there was more than the moon up that evening and treated them to a storybook thin-crescent Venus, a tiny orange Mars, and the usually stunning Saturn. Most of them had never looked through a telescope and they loved it. I even got a hug from the adorable little girl on the step ladder in the picture. ( Mike was jealous… )
We also took in Rasalgethi and Iota Cancri and the folks remarked that they didn’t know stars were different colors.
I am finally finishing the ETX articles and want to print a small section on the fever that one time or another has infected all of us.
This is the opening paragraphs of reason number nine of why I believe the ETX 90RA the Greatest Telescope on Earth. I think it puts things in perspective. What do you think?
“When someone is considering getting a telescope it is usually the result of Telescope Fever.
Telescope Fever is a malady that has only two known cures: the actual purchase of the equipment, or a sobering review of one’s bank statements. In some instances the bank statement review only delays the onset of equipment purchase. Telescope Fever dulls the senses and causes obsessive fixations on usually a single piece of equipment and two questions:
1. What can I see with it?
2. How much does it cost?
(A variation on number one is: How many bells and whistles does it have?)
The person at this point is totally immersed in telescope review sites and flashy magazine articles – usually ignoring the more negative comments because secretly they have already made up their minds. They might wait for a star party and actually look through one of the scopes they are considering, but this is pretty rare and goes against traditional “telescope fever” protocol.
The telescope is purchased and delivered and only then do the symptoms of “telescope fever” begin to subside. The head clears and additional questions begin to surface:
3. How do I put this thing together ( the instructions are usually lacking in one or more areas)
4. How do I operate this thing once I do put it together?( crew-served telescopes are not unheard of)
5. Where am I going to store this thing? (perhaps a large barn?)
6. How am I going to move this thing to a dark site? ( Check the GCVW specs on your tow vehicle)
7. Where’s the rest of it? (Didn’t all those accessories shown in the magazine come with the base package?)
8. Who can I talk to about all of this? ( The factory?…. the high end scopes usually have great factory support, …the others?)
The answer to question No. 8 usally leads to the answers to the other questions. This is where the vendors and users groups comes in.”
When we finally make the jump to fully colonizing the Solar System, we're going to want to use asteroids as stepping stones. We can use them as way stations, research facilities, even as spacecraft to further explore the Solar System. Today we'll talk about the science and science fiction of hollowing out asteroids.
Astronomers rely on the optics of their instruments, and there are some basic limits that you just can’t avoid. Whatever we look at is distorted by the optics, in fact, a basic property of light means that we’ll never get perfect optics. Here’s why we can’t “magnify and enhance” forever.
