This year's annual Perseid meteor shower takes place between the dates 17th July and 24th August, peaking on the night of 12/13th August, with a formal maximum in the small hours of Wednesday 13th August. ... This is the most famous of all meteor showers and rarely fails to provide an impressive display. ... Comet Swift-Tuttle takes approximately 130 years to make one circuit around the Sun, and sheds particles when closest to the Sun in its orbit. ...

A long Chandra observation of Tycho has revealed a pattern of X-ray "stripes" never seen before in a supernova remnant. The stripes are seen in the high-energy X-rays (blue) that also show the blast wave, a shell of extremely energetic electrons. ... The stripes may provide the first direct evidence that a cosmic event can accelerate particles to energies a hundred times higher than achieved by the most powerful particle accelerator on Earth. ...

... It turns out one possibility is a form of matter/energy invented by Einstein in the 1920s to make sure his equations of General Relativity did not predict the Expansion of the Universe. Although Einstein was willing to predict several things with his equations of General Relativity, he obviously thought an expanding Universe was too much, and so he invented the Cosmological Constant, which repels itself, and was meant to balance the force of gravity, and make the Universe static. ...

Not all meteors are sporadic events, the regular meteor showers occur when the Earth bulldozes through a great swarm of meteoroids drifting in orbit round the Sun. ... They are at their best in the pre-dawn hours, as the face of the Earth turning towards the Sun catches more meteors as the Earth moves through space. ...

... Take the air we breathe: its molecules have energies around 0.03 ev (electron volt--see energetic particles ) as fast as a cannonball, though still quite a bit slower than the typical satellite. ... The Sun's plasma is much hotter , and that of the magnetosphere is still hotter. ... They are known as cosmic rays or cosmic radiation . ... Actually, the source of cosmic rays is probably not quite as intense, because cosmic ray particles can stay around the galaxy much longer than starlight. ...

... Supernova 1987A (LMC) . ... Type I: thermonuclear runaway in a red-dwarf/white-dwarf binary . ... At present, such an event is unlikely, since the nearest potential Type I supernova is at least 50 light years distant, and the nearest Type II ~1500 light years away (in Orion). However, the Sun orbits the Galactic Centre once every 100 million years; every ~30 million years, or so, it passes through a Galactic spiral arm - major sites for star formation, regions with many, short-lived massive stars. ...

After 30 years of bewilderment, astronomers finally know that collapsing massive stars generate most gamma-ray bursts. Gamma-ray bursts (GRBs) were first detected in the late 1960s by American military satellites designed to monitor Soviet compliance with the Nuclear Test Ban Treaty. ...

... The Earth's magnetosphere is not unique. Space probes which have visited the giant planets--Jupiter, Saturn, Uranus and Neptune--found that all were magnetized, even more intensely than the Earth, and all were surrounded by radiation belts. ... The earliest evidence came from cosmic rays , discovered in 1912 by Victor Hess. ... In the biggest events, a few times each solar cycle, such ions spread throughout interplanetary space, at energies which can reach those of low-energy cosmic rays. ...

K-band Arcetri Obscured Supernova Search . What is the KAOSS Project? W hat is the KAOSS Project? Some recent surveys aimed at detecting Supernovae (SNe) in the optical have found that starburst galaxies do not show evidence for an enhanced SN rate, with respect to quiescent galaxies (Richmond et al. ... A similar result was obtained by Navasardyan et al. (2001) who looked for SNe in interacting galaxies, finding no evidence for correlations between SN rate and galaxy properties. ...
