Flooding on a scale that devastated parts of England last year is set to become a common event across the UK in the next 75 years, new research has shown. A study by Dr Hayley Fowler, of Newcastle University, predicts that severe storms the likes of which currently occur every five to 25 years across the...
The 100km-wide asteroid (626) Notburga will occult the fairly bright star (magnitude 7) 36 Aquarii (HIP 109369) on Saturday, 10th January 2009 at about 18:07 UT. The event will be observable from central Britain and southern Ireland...
Whitby could be turning into a UFO hotspot with yet more reports flooding into the Gazette offices of mysterious lights in the sky. The phenomenon has also been spotted in other parts of the country and even hit the front page of a national newspaper yesterday when a UFO was believed to have hit a 300ft w...
Many city-based amateur astronomers believe you need to dark country skies to see faint deep-sky objects like galaxies and nebulae. But if you live in a decent-sized city it takes time and energy (and more than a few dollars) to truck your telescope out an hour or so outside of the city. And the harder y...
British scientists have opened a new window on the Universe with the recent commissioning of the Visitor Instrument ULTRACAM on the European Southern Observatory's (ESO) Very Large Telescope (VLT) in Chile.
ULTRACAM is an ultra fast camera capable of captur...
A full-size prototype of the newest Mars rover is now on display at the Fleet Science Center. The new rover is still nameless, according to museum officials but K-12 students can enter a contest to name the vehicle. The winning student will win a trip to NASA's Jet Propulsion Lab in Pasadena, where the...
NASA and the National Science Foundation have successfully launched and demonstrated a newly designed super pressure balloon prototype that may enable a new era of high-altitude scientific research. The super-pressure balloon ultimately will carry large scientific experiments to the brink...
