Over the years, scientists have debated the cause of the mass extinction that wiped out the dinosaurs 65 million years ago. Now, a panel of 41 international experts says it's official: a massive asteroid around 15 kilometers wide slamming into Earth at Chicxulub, Mexico is the culprit. After surveying a wide variety

Left Panel, asteroid Vesta as seen from Mars on the 11th of February (for Earth reference see here), Right Panel, Vesta as seen from Mars at the time of Opposition on Mars on & May 2010. Image visualized in Stellarium, location approximately latitude of Adelaide on Mars (as always, click to embiggen). In my series of posts about seeing things from other worlds, (opposition of Mars from Mars and Venus), I'm having a look at the opposition of the asteroid Vesta. (My photographs and sketches her

The North-east horizon as seen in Australia at 11 pm local daylight saving time (10;00 pm non-daylight saving time) showing the location of Vesta (click to embiggen). While Mars is the focus at the moment, another opposition is upon us. That of the asteroid Vesta. Remember, an opposition is any time we are directly between an astronomical object and the Earth. Oppositions of Mars and Jupiter can be spectacular, but even humble chunks of rock can have oppositions. We generally don´t notice th...
