Employing the help of the Mini-SAR instrument (a lightweight, synthetic aperture radar), NASA managed to find more than 40 craters covered with ice. Despite the fact that the craters are relatively small, it’s estimated that there is about 600 million metric tons in that area. “The emerging picture from the multiple measurements and resulting data of [...]

Pluto is so upset that it’s no longer a planet, that it’s turning all red with anger ! No, seriously. There’s been a whole lot of “Pluto-related news” these days including the 2006 chalking off of the planet list, and naming it a “dwarf planet”, and the news just gets better and better. Recently, astronomers were [...]

As I was writing in a previous post, Titan is quite unique, in that aside from our planet it’s the only place in our solar system where significant quantities of liquid are to be found (though most are liquid ethane and methane). That doesn’t seem to make much of a difference considering the chemistry of [...]

It was Thursday night when locals from Norway started to notice a strange, rotating light that just baffled them. It was visible long enough to be seen, photographed and recorded by half of country. The blue light seemed to appear from behind the top of a mountain; it rose, began to spin, then began to [...]

Star clusters are among the pretties things you can see, when it comes to astrophysical observations. Recently, ESO provided some amazing pictures of one of the most beautiful nestles ever to be seen, located deep in the constellation of Crux. The cluster is named Kappa Crucis Cluster and has been nicknamed ‘the jewel box’ (by Herschel, [...]

We’ve all seen at least one movie in which our planet is destroyed, but most of them were quite repetitive and kind of uninteresting. Our planet deserves so much more! Black holes Well, it seems the more we understand things about black holes, the more we find out things we don’t know, and the more we fear [...]

Ram pressure is the pressure exerted on a body when it passes through a fluid medium; this causes a drag force that is exerted on the body. The same pressure appears when a galaxy is moving through an intergalactic gas, and in this case, the ram pressure can sweep a significant part of the intergalactic [...]

Stormy weather conditions may delay the launch of space shuttle Endeavour, currently scheduled for liftoff on Saturday, July 11. This comes on the heels of two delays last month caused by a hydrogen gas leak. A similar problem delayed the launch of space shuttle Discovery in March. The 16-day mission will feature a number of spacewalks [...]

Unfortunately for some, the green visitor is not an alien coming to greet us but something else, even though it also comes from far, far away. On the 24th of February the comet Lulin will pass within 61 million kilometers of Earth, thus being able to be seen with the naked eye from some locations. This [...]

As we learn (or at least should) at quite an early age, Galileo Galilei made numerous improvements in telescopes and made early observations of the Moon, making the first map of our planet’s satellite. Right? Wrong. Despite the fact that he will always remain “father of modern observational astronomy” and his name will be forever [...]
