The very latest in the Celestron line is the Celestron EdgeHD – an Aplanatic Schmidt optical system that produces pinpoint star images all the way to the edge of the field. Some optical systems currently on the market may produce coma free images. But there is a difference…. the optical difference. Not only is the Celestron EdgeHD telescope coma free, but it also has a built in field flattener to ensure sharp focus all the way to the edge of the field, producing true Astrograph quality images. This results in pinpoint, High Definition star images throughout your astro photograph! These superior features combined with the Celestron CGE Pro and CGEM mounts make the new Celestron EdgeHD series the new gold standard in Astro Imaging and the system of choice for the serious astro-imagers.
Celestron EdgeHD Telescopes are available for order at OPT – www.optcorp.com !

The Sun and stars emits radio waves — not just visible and infrared light. In the 1930s, Karl Jansky built the first devise to “listen” to the sun, collecting radio waves from far off stars and focusing them onto a detector. This invention provided astronomers with a completely different view of the Universe — prompting the discovery of radio stars, quasars, and black holes.
This video features a model of the Algonquin Radio Observatory (ARO), located in Ontario’s Algonquin Provincial Park. In 1968, astronomers combined signals from the ARO with those from the Dominion Astrophysical Radio Observatory in Penticton, British Columbia forming a new instrument called a Long Baseline Interferometer.

In this episode, we’ll look at a couple of bogus attempts to undermine science related to Lunar and Solar astrophysics.
I apologise for the somewhat erratic sound/volume in this video. I did not record it all in one go, and I have no idea what I’m doing in iMovie. The next one will be better.
To those who were referred to me by DonExodus2, thank you for checking out my videos and I hope you’ll like what you see enough to subscribe.
To DonExodus2 himself, thank you very much indeed for your support.

Errata:
1. I apologise, this is just completely wrong. It was thought up until 1965 that Mercury was tidally locked to the Sun, but was proven to have 3:2 spin orbit resonance. That means for every 2 years on Mercury, there are 3 days. One Mercurian year is about 88 Terran days and one Mercurian day about 59 Terran days. I think I was once told that Mercury *was* thought to be tidally locked with the Sun, and confused that to mean it was the current consesus. Again, sorry!

NASA scientist David Morrison shares some of the most outrageous questions and comments he has received regarding 2012 and Nibiru (“Planet X”) conspiracies. One of his favorites? “I am getting tired of all the CIA and NSA planes buzzing around my house in circles like I am some freak at a carnival show.”

This program was recorded in collaboration with the 2010 SkeptiCal Conference, in Berkeley, CA, on April 24, 2010.
Dr. David Morrison is the Director of the NASA Lunar Science Institute and Senior Scientist for Astrobiology at the NASA Ames Research Center. He holds a Ph.D. in astronomy from Harvard and is internationally known for his research on small bodies in the solar system, including advocacy for developing plans to defend the Earth from impacts by comets and asteroids.
A Fellow of CSI, he has written extensively on such fringe science topics as Velikovsky, cosmic catastrophes, UFOs, the creation science movement, and most recently the climate crisis caused by global warming. For the past two years he has been the primary scientist critic of the widespread fear that the world will end in 2012, and of the doomsday sleaze artists who use the Internet, blogs, and cable TV to frighten people for profit.
Dr. Morrison’s discussion largely centers around the hoax of 2012. – SkeptiCal Conference
David Morrison is the senior scientist at the NASA Astrobiology Institute, NASA Ames Research Center, Moffett Field, Calif., where he participates in a variety of research programs in astrobiology — the study of the living universe.
Dr. Morrison obtained his doctorate in Astronomy from Harvard University. He is the author of more than 155 technical papers and has published a dozen books. He has been a science investigator on NASA’s Mariner, Voyager and Galileo space missions. Morrison is recipient of the Dryden Medal for research of the American Institute of Aeronautics and Astronautics, the Sagan Medal of the American Astronomical Society for public communication, and the Klumpke-Roberts award of the Astronomical Society of the Pacific for contributions to science education. He has received two NASA Outstanding Leadership medals and he was awarded the Presidential Meritorious Rank for his work as director of space at NASA Ames. Morrison was a founder of the multidisciplinary field of astrobiology, and he provides on-line answers to questions from the public sent to “Ask an Astrobiologist,” found at: http://nai.arc.nasa.gov/astrobio/
Morrison is perhaps best known for his leadership since 1991 in defining the hazard of asteroid impacts and seeking ways to mitigate this risk. Asteroid 2410 Morrison is named in his honor.
