Telescopes on six solar observation satellites are currently monitoring the sun. The satellites include Japan's Hinode and the SDO developed by the United States. Solar activity (flares, sunspots) is at its lowest since modern observation began - what implications does this have for our Earth?
Double stars are stars that appear to be near each other in the sky, but if they’re gravitationally bound together we call them binary stars. Many stars are actually part of binary or multiple systems. If they are close enough together they can actually touch other, merging into one peanut-shaped star. In some close binaries matter can flow from one star to the other, changing the way it ages. If one star is a white dwarf, this can cause periodic explosions, and possibly even lead to blowing up the entire star.
Mammals have adapted to live almost anywhere - from freezing polar regions, to the hottest deserts and from steaming jungles, to the world's vast oceans. They survive on a great variety of different foods and it's what they eat that so often determines their behaviour - and that of course, includes our own.
