... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . Nearly 50 years ago, Dr David Andrews , a former Astronomer at the Armagh Observatory, discovered a new minor planet or asteroid. It was discovered on the night of 25th January 1965, and the object eventually received an official number (1727) and the name "Mette" , named by the discoverer in honour of his wife, "for her tolerance of my nocturnal working hours and for the many months spent away from home". ...

11. First X-Rays From a Comet Discovered
A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...

... This is the truly fun part, observing molecular and atomic gas in star-forming regions with a variety of telescopes. Depending on the temperature and density of the gas, different observations are necessary to study the components of star-forming regions. Because stars form in cool gaseous regions, I most often use radio and sub-mm observations, but I also look for opportunities to make complementary observations using infrared and optical telescopes. ...
