(JPL) When NASA’s Juno spacecraft flew past Earth on Oct. 9, 2013, it received a boost in speed of more than 8,800 mph (about 3.9 kilometers per second), which set it on course for a July 4, 2016, rendezvous with Jupiter, the largest planet in our solar system. One of Juno’s sensors, a special kind of camera optimized to track faint stars, also had a unique view of the Earth-moon system. The result was an intriguing, low-resolution glimpse of what our world would look like to a visitor from afar.
“If Captain Kirk of the USS Enterprise said, ‘Take us home, Scotty,’ this is what the crew would see,” said Scott Bolton, Juno principal investigator at the Southwest Research Institute, San Antonio. “In the movie, you ride aboard Juno as it approaches Earth and then soars off into the blackness of space. No previous view of our world has ever captured the heavenly waltz of Earth and moon.”

Temperatures have been below normal for a week, and aren’t expected to return to average levels until early next week. The warmer weather we are forecasting during the early and middle part of next week may be short-lived, as a bitterly cold Arctic air mass will plunge southward into Texas by late Thursday, according to computer weather models.

Dec. 10, 2013: What is the coldest place on Earth? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.
Scientists made the discovery while analyzing the most detailed global surface temperature maps to date, developed with data from remote sensing satellites including the new Landsat 8, a joint project of NASA and the U.S. Geological Survey (USGS). Ted Scambos, lead scientist at the National Snow and Ice Data Center in Boulder, Colo., joined a team of researchers reporting the findings Monday at the American Geophysical Union meeting in San Francisco.
With remote-sensing satellites, scientists have found the coldest places on Earth, just off a ridge in the East Antarctic Plateau. The coldest of the cold temperatures dropped to minus 135.8 F (minus 93.2 C) — several degrees colder than the previous record. Image Credit: Ted Scambos, National Snow and Ice Data Center
Researchers analyzed 32 years’ worth of data from several satellite instruments. They found temperatures plummeted to record lows dozens of times in clusters of pockets near a high ridge between Dome Argus and Dome Fuji, two summits on the ice sheet known as the East Antarctic Plateau. The new record of minus 136 F (minus 93.2 C) was set Aug. 10, 2010.

The first Winter Weather Advisory for portions of the KXAN viewing area has been issued. This Advisory includes San Saba and Mason counties, and begins Thursday night. It is highly likely that additional advisories will be issued for more of the KXAN viewing area in the next 48 hours. These advisories may include the Austin metro area. Check with First Warning Weather frequently for important information on this developing winter storm, and watch KXAN News for detailed analysis.
An arctic cold front will bring much colder temperatures and a chance for wintry precipitation to portions of West Central Texas Thursday and Friday. Freezing rain is expected to develop along and north of Interstate 20 on Thursday morning, spreading south Thursday night into early Friday. Sleet, and some snow, is forecast to accompany the freezing rain north of a San Angelo to Brownwood line. In the Winter Storm Warning, expect ice accumulations to remain less than 1/4 inch with snow/sleet accumulations near 1/2 inch. Farther south, sleet accumulations will remain very light with ice accumulations of less than 1/4 inch.
