A comet is heading for Mars, and there is a chance that it might hit the Red Planet in October 2014. An impact wouldn’t necessarily mean the end of NASA’s Mars program. But it would transform the program along with Mars itself.
Forecasters say solar maximum is due in 2013. To prepare, the UN is organizing an international response to stormy space weather.
Something unexpected is happening on the sun. 2013 is supposed to be the year of Solar Max, but solar activity is much lower than expected. At least one leading forecaster expects the sun to rebound with a double-peaked maximum later this year.

The giant sunspot was captured on camera by NASA’s Solar Dynamics Observatory as it swelled to enormous proportions over the 48 hours spanning Tuesday and Wednesday (Feb. 19 and 20)…. Read more →
Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun’s atmosphere, the corona. On July 19, 2012, an eruption occurred… Read more →
Despite the huge size of the Russian meteor, its appearance in the skies was a surprise. It entered Earth’s atmosphere completely unnoticed by anyone. <iframe width=”540″ height=”304″ src=”http://www.youtube.com/embed/58KLko50yE4″ frameborder=”0″ allowfullscreen></iframe>

An asteroid as large as an Olympic swimming pool will race past the Earth on Friday at a distance of just 27,700km (17,200mi) – the closest ever predicted for an object of that size. It will pass closer even than the geosynchronous satellites that orbit the Earth, but there is no risk of impacts or collisions. Its closest approach will… Read more →
A meteor streaked through the sky and exploded Friday over Russia’s Ural Mountains with the power of an atomic bomb, its sonic blasts shattering countless windows and injuring more than 750 people. The spectacle deeply frightened thousands, with some elderly women declaring the world was coming to an end. The meteor — estimated to be about 10 tons — entered… Read more →
