On the Astronomy Show today I will be looking at the discovery of a crater under the ice on Greenland. The crater is nearly 20 miles wide and its impact would have had a massive effect on the Earth's climate. It is believed to have been formed between 3 million and 12,000 years ago.
The regular features on the show include a look at what is in the night sky during the next week including identifying that really bright white object in the sky in the East before sunrise. The astronomy news includes details that show that the Earth has been near missed 66 times so far this year by asteroids, Voyager 2 creeps closer to the edge of the solar system and NASA plan to land the 2020 mission to Mars in an ancient lakebed to search for signs of life.
Other regulars include the A-Z of constellations which is now at Taurus the Bull while the Messier Marathon will look at M 80 in Scorpius. The astronomical scrapbook looks at anniversaries this week which include a comet discovered in York in 1783, and the first transit of Venus observed in 1639. All this plus the usual round up of what is going on in the astronomical societies in the North of England.
The Astronomy Show every Wednesday afternoon between 3.00 pm and 5.00 pm only on Drystone Radio 103.5 FM. You can hear the show on line at www.drystoneradio.com or catch the show later on the Drystone Radio podcast.
