On December 12, the three-mile-long 4.8 km asteroid Toutatis came within 4.3 million miles 6.9 million k stanley cup m of Earth 鈥?which is about 18 lunar distances. During the flyby, NASA used its 230-foot-wide 70-meter Deep Space Network antenna at Goldstone, California, to generate a series of stanley cups uk radar data images 鈥?which has revealed a slowly spinning and oddly shaped asteroid in fairly spooky detail. The resolution of the image is at 12 feet 3.75 meters per pixel, and the video is only 64 frames in length 鈥?but it shows an asteroid that elongated and irregularly shaped. Ridges can be clearly seen, and possibly some craters. The astronomers also noticed some bright glints 鈥?what might be surface boulders. The video also shows that Toutatis is spinning quite slowly. It rotates along its long axis every 5.4 days, and the orientation of its rotational axis precession changes every 7.4 days; NASA describes it as a wobbly football that has been thrown very stanley website poorly. And as for Toutatis posing a threat to Earth, it not. The asteroid won ;t visit us again until 2069 when it will come within 7.7 lunar distances 1.8 million miles or 3 million km . Models indicate that there is a zero chance that it will hit the Earth within the next four centuries 鈥?which is the longest interval that estimates can be made.

Brain size can vary tremendously between species. For instance, the average human head holds around three pounds of cerebral matter; your typical chimp, on the other hand, packs about a third of that stanley us . Differences in brain size do exist within species women, for stanley cup example, have relatively larger brains than men , however such variations are usually small. Not so for the three-spined stickleback. Cloistered away in Iceland Lake M媒atn, a tiny population of these torpedo-shaped fishes is one of the only known examples on Earth where the males of the species possess dramatically larger brains than females. In a study published in the latest issue of PLoS ONE, a team of researchers led by Alexander Kotrschal of Sweden Uppsala University weighed the brains of 58 m stanley botella ale sticklebacks and 61 females. While all of the specimens were around 4.5 centimeters in length, the typical male brain weighed in at 24.2 milligrams, while the females ; weighed an average of just 19.7 mg. The underlying reason for this disparity 鈥?clearly noticeable in the male and female stickleback brains seen here 鈥?is unknown, but the researchers hypothesize that it has to do with two of most important activities in nature: sex and parenting. Male sticklebacks from the M媒vatn population have been the subject of behavioral investigations for decades on account of their complex mating rituals and fastidious child-rearing habits, while females are known to dedicate up to 40 percent of their body
