- The first snow storm of 2006 dumped several inches of snow across a wide swath of the Midwest, with snowfall totals from four to five inches recorded in Chicago to as much as a foot just north of the city. Beyond the traffic accidents caused by icy roads, the storm was not a remarkable one. It did, however, leave a clear track across the Midwest and the Great Lakes region. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of the storm on January 21, 2006, a day after the snow fell. The deep blue waters of Lakes Michigan, left, and Huron, right, stand out starkly against the background of white. Remarkably, the lakes show no sign of freezing. At this time in 2005, the shores of both lakes were fringed with ice. January 2006 has been warmer than average across the United States. Average weekly temperatures in the area shown in this image have ranged from 5 degrees Celsius above average to more than 8.3 degrees Celsius above average, according to the National Climate Data Center.
- Hubble Deep Field (Wikipedia)
The Hubble Deep Field (HDF) is an image of a small region in the constellation Ursa Major, constructed from a series of observations by the Hubble Space Telescope. It covers an area about 2.6 arcminutes on a side, about one 24-millionth of the whole sky, which is equivalent in angular size to a tennis ball at a distance of 100 metres. The image was assembled from 342 separate exposures taken with the Space Telescope’s Wide Field and Planetary Camera 2 over ten consecutive days between December 18 and 28, 1995.
