Giant Natural Particle Accelerator Above Thunderclouds A lightning researcher at the University of Bath has discovered that during thunderstorms, giant natural particle accelerators can form 40 km above the surface of the Earth. On Wednesday 14th April Dr. Martin Fullekrug will present his ne...
Planetary Nebula Abell 63 Abell 63 was the first planetary nebula to be shown to host a binary central star, and has since been shown to be an archetype system. This image taken with the WFC shows the nebula to comprise a central barrel-shaped structure along with two caps of emission ejected along the...
Scientists uncover the secret of the perfect cuppa Researchers at Northumbria University have revealed the formula for making the perfect cup of tea for British taste buds. The team, from the School of Life Sciences, were commissioned by milk manufacturers Cravendale, to discover the secrets be...
Antarctic Peninsula ice more stable than previously thought An international team of researchers, led by the UK Centre for Polar Observation and Modelling at the University of Leeds, is the first to map the change in ice speed. The team collated measurements recorded by five different satellites...
Specially designed Cassini orbits place Earth and Cassini on opposite sides of Saturn's rings, a geometry known as occultation. Cassini conducted the first radio occultation observation of Saturn's rings on May 3, 2005.
Three simultaneous radio signals of 0.94, 3.6, and 13 centimetre wavele...
AG Pegasi is a symbiotic binary star in the constellation Pegasus. It is a close binary composed of a red giant and white dwarf, estimated to be around 2.5 and 0.6 times the mass of the Sun respectively. Initially a magnitude 9 star, AG Pegasi brightened and peaked at an apparent magnitude of 6.0 around...

A team of astronomers from Cardiff University and the University of Washington Seattle reports in the journal 'Nature' this week that they have discovered that galaxies are much simpler than anybody thought. Galaxies are enormous whirlpools of stars, and the Sun is but one star in our own Milky Way...
This week, researchers will begin direct monitoring of the rumblings of a submarine volcano in the south-eastern Caribbean Sea. On May 6, a team of scientists led by the Woods Hole Oceanographic Institution (WHOI) installed a new underwater earthquake monitoring system on top of Kickem Jenny, a v...
