The concept for this eyepiece was first proposed by Tele Vue President David Nagler, with performance parameters giving it the fundamental characteristics (the ethos) of a Tele Vue eyepiece high contrast, comfortable eye relief and full field sharpness. Control of astigmatism, field curvature, lateral color, angular magnification distortion correction and low pupil sensitivity for daytime use were specified criteria.Following Tele Vue #39;s philosophy of pushing the state of the art, long-time Tele Vue employee and optical design protg Paul Dellechiaie took up the challenge and designed the basic eyepiece form. Under Al #39;s guidance, Paul tweaked his design to fulfill the original goals.While sharpness is inherent to the optical design, contrast is maximized through the intelligent use of flat finished baffles and ultra low reflectance, high efficiency coatings tuned to the composition of each element.At the 2007 Northeast Astronomy Forum, Tele Vue once again broadened the amateur astronomer #39;s perspective on the universe and introduced a new observing experience; 100 of pure Tele Vue quality.

Remembering Carl Sagan (November 9, 1934 -- December 20, 1996)
Today would have been Carl Sagan #39;s 78th birthday, and the past few years November 9th, the anniversary of his birth, has been designated as "Carl Sagan Day" by people who appreciate Sagan #39;s influence mdash; not only on science, but also the public #39;s understanding of it. Sagan passed away 16 years ago, but his words and inspiration live on for many of us through his books and recordings. Carl Edward Sagan was an American astronomer, astrophysicist, cosmologist, author, science popularizer and science communicator in astronomy and natural sciences. He spent most of his career as a professor of astronomy at Cornell University where he directed the Laboratory for Planetary Studies. He published more than 600 scientific papers and articles and was author, co-author or editor of more than 20 books. He advocated scientifically skeptical inquiry and the scientific method, pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). Sagan is known for his popular science books and for the award-winning 1980 television series Cosmos: A Personal Voyage, which he narrated and co-wrote.The book Cosmos was published to accompany the series. Sagan wrote the novel Contact, the basis for a 1997 film of the same name.From:GremlinTaleViews:0 0ratingsTime:01:38More inScience Technology

Lost in the Lagoon (Nebula, Astronomy) - Video

I dont like childrens music. Its nearly always synthesized music with high-pitched melodies and dumb lyrics. It takes as little skill to memorize as it takes to memorize the latest hip hop songs that are all chorus and no verse. However, the world occasionally throws you a little gem of a childrens music album and your faith in the future of human kind is restored. Such a gem is the new science and astronomy-themed The Mighty Sky.

The Mighty Sky is the brainchild of songwriters Beth Nielsen Chapman, Annie Roboff, and the Vanderbilt Dyer Observatory director Rocky Alvey. Each song has a a different genre, from country to blues and even a little rock. Each song also focuses on a different theme:

Some of my favorite excerpts from the lyrics:

If the Sun was the size of a basketball That would make the solar system small The Earth would only be a grain of sand You could hold the planets with one hand ***** Her career was finished and her bright days were done Shed been up on the stage shed outshined the Sun All the other stars said its time to move over But man they got an eyeful when she went supernova ***** The Moon looks big at rise and set And smaller when it climbs up high Its the very same thing if you measure it The Moon is good at fooling our eyes ***** In summer Earths farther away from the Sun In winter its closer they say So distance just isnt why you freeze your buns Your hemispheres tilting away ***** The electromagnetic spectrum, is making a lot of waves You know that they go from radio, to energetic gamma rays But you can see the blues, in all the visible hues The colors of the rainbow, are the energies that we use

The Mighty Sky website includes samples of the songs and all the lyrics, so go check it out if youre curious about this album. The website will also soon include lesson plans themed around each song, but for now The Mighty Sky team has provided me with some sample lesson plans to share with you about the moon phases and sunlight timeline.

Our Curious George obsessed two-year-old is now requesting to dance (listen to The Might Sky) over watching Curious George on TV, which is kind of a big deal. The whole family has listened to this album countless times already and we simply havent gotten bored or annoyed with it. I dont think singing along about the scientific method will ever get old.

Ariane is a programmer married to another programmer. Together they are raising their 2-year-old daughter, who doesn't stand a chance against her nerdy lineage.

The Mighty Sky: Learn Astronomy Through Music

[Today is Carl Sagan's birthday, celebrated by lovers of science and rationality around the planet. I wrote the following post last year, but I think it's still appropriate (and I updated his age). Happy birthday, Carl. It's a darker cosmos without you, but we still walk with the candle you lit for us.]

If Carl Sagan were still alive, hed be 78 years old today. Perhaps he wouldnt have been overly concerned with arbitrary time measurements, especially when based on the fickle way we define a "year", but its human nature to look back at such integrally-divisible dates and Carl was very much a student of human nature.

Ive written about him so much in the past theres not much I can add right now, so I thought I would simply embed a video for you to watch but which one? Where James Randi eloquently and emotionally talks about his friendship with Carl? Or the wonderful first installment of Symphony of Science using my favorite quote by Carl? Or this amazing speech about how life seeks life?

But in the end, the choice is obvious. Carl Sagans essay, "Pale Blue Dot", will, I think, stand the test of time, and will deservedly be considered one of the greatest passages ever written in the English language.

Happy birthday to Doctor Carl Sagan, Professor of Astronomy, scientist, skeptic, muse, and though he may not have thought of himself this way poet.

Ill leave you with this, something I wrote abut Carl a while back, when asked about what his greatest legacy is:

Sagans insight, his gift to us, is the knowledge that we all have the ability to examine the Universe with all the power of human curiosity, and we need not retreat from the answers we find.

Repost: Carl Sagan Day | Bad Astronomy

Of all the amazing pictures returned from the moon by the Lunar Reconnaissance Orbiter and I may include the Apollo landing sites among them I think my favorites are the ones showing boulders that rolled down slopes.

Did I say rolled? I mean bounced!

[Click to enselenate.]

This shot from LRO shows the floor of crater Shuckburgh E, an impact crater about 9 km (~6 miles) across. The image shows a region about 655 meters (0.4 miles) across. The crater floor here is not level; its tilted up from left to right, and also has contours. Boulders dislodged for some reason (a seismic event, or a nearby impact) on the right have rolled down to the left and some actually skipped along, bouncing and bounding as they did.

The two biggest trails are dashed, indicating the boulders had a bit of a rollicking time before coming to rest. You can see both boulders at the left of the trails, where they came to a stop. Note that the sunlight is coming from the bottom of this picture, which can play tricks on perspective. I see the boulders looking almost like craters and the skidding trails they left like little mounds. If you flip the picture over it may look better to you.

As always, pictures like this are a strong reminder that even on the Moon, where time stretches long and processes are slow, changes do occur. Maybe not often, and maybe not recently, but given enough time you have to think of the Moon as a dynamic place.
