He has a PhD in astronautics and is the inspiration behind the character "Buzz Lightyear" in the movie "Toy Story". He made history when he, along with Neil Armstrong, were the first human beings to ever step on the moon during [...]

Kepler discovers 5 new exoplanets

On March 6, 2009, the Kepler space telescope was launched from Cape Canaveral with a primary mission to find Earth sized planets in a habitable zone around stars similar to our own by continuously and simultaneously observes more than 150,000 stars. Kepler's instrument, has measured hundreds of possible planet signatures which are currently being [...]

Perihelion – Earth closest to the Sun

Perihelion – Earth closest to the Sun

You may know that we don't have a circular orbit around the Sun. Its elliptical, that means at one point we are closest, and at another we are the furthest point away. So just about now, January 2/3 2010, the Earth will be at perihelion, the closest point on its elliptical orbit to the Sun. The Sun’s center will be 147,098,040 kilometers away [...]

Saturn Moon Ballet

Nice video of Saturn and it's moons in a dance to the sound of the nutcracker. Very festive!....It is a combination of 61 images taken from Cassini.

Tips on setting up and using your new Galileoscope

Tips on setting up and using your new Galileoscope

Its a terrible thing to get a telescope as a present and not know what to look at or indeed how to use it. Since I know quite a few people who got a galileoscope as a present, I thought it might be a good idea to give a few tips and pointers. So here are some simple things you should know. Please note: The Galileoscope is NOT a solar [...]

Orions Belt in gorgeous detail

Explanation: Alnitak, Alnilam, and Mintaka, are the bright bluish stars from east to west (left to right) along the diagonal in this gorgeous cosmic vista. Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie about 1,500 light-years away, born of Orion's well-studied [...]

Light and Dark – Saturn reveals its unique beauty!

Light and Dark – Saturn reveals its unique beauty!

I just love this high contrast image from Cassini. It seems that every second image released from cassini is just so stunning. This shows a stunning contrast between dark and light of Saturn, its rings and its moons Dione and Enceladus. Details on the image from Nasa regarding this image "Saturn's northern and southern latitudes appear dark [...]

Titan casts a large shadow…

Titan casts a large shadow…

Titan (5150 kilometers, 3200 miles across) is Saturn's largest moon  but is not pictured here. What you can see is its elongated shadow below  Saturn's rings in this newly released image from Cassini. This view looks toward the northern, sunlit side of the rings from just above the ringplane. The view was obtained at a distance of approximately [...]

Lakes on Titan- Cassini catches a glint!

Lakes on Titan- Cassini catches a glint!

This is a sunlight reflection (a specular reflection) from Saturn's Moon Titan. It was detected by the visual and infrared mapping spectrometer (VIMS) on NASA's Cassini spacecraft on July 8, 2009. It confirmed the presence of liquid in the moon's northern hemisphere. That's pretty rare! Titan is likely the only other moon/planet with a liquid on [...]

The Known Universe

The Known Universe

Its crazy just how small a space we actually occupy in the known universe. This video is another attempt to show us just how big the universe is. It uses the usually technique of speed up by orders of magnitude as it moves away from the Earth. Somehow that doesn't quite give me a real sense of scope. It was well made and I liked the bit where it [...]
