Red Shift

Science Daily March 26th ( id 100325091430) - Astronomers at Leiden Observatory conducted an intensive survey of 446,000 galaxies in what is known as the COSMOS survey. Hubble photographed 575 slightly overlapping views of the same part of the universe which took 1000 hours. Researchers also used redshift dta from ground based telescopes to assign distances to the galaxies (out to red shift 5) which confirms Einstein's Theory of Relativity and the idea of accelerating cosmic expansion.

Mapping Venus

At March 22nd ... is another incredible piece of research. The article has a computer generated image of the surface of Venus created from radar images taken during NASAs Magellan mission during the 1990s. Peter James, a graduate student in the Earth and Planetary Sciences, has shown that plate tectonics do not seem to apply on Venus - or Mars and Mercury.

Water on the Moon id188149607 ... it was thought the Moon was the driest place in the solar system - but now we have reports of moon water 'pouring' in . Some 600 million metric tons of water distributed in 40 moon craters near the moon's north pole, have been discovered (possibly conjectural). NASA's mini-SAR radar imagining instrument onboard India's Chandrayaan spacecraft is responsible for the turn around in view.

Red Spot

The Daily Galaxy, March 17th ) - 'Unlocking the Secrets of Jupiter's Giant Red Spot' claims the red spot is a region of storminess, the reddest bits a warm core within an otherwise cold storm system. The findings come from an article in Icarus but see also where thermal images show the red spot in greater clarity than ever before.

Black Hole Fireworks

Daily Galaxy March 15th ( ) ... 'The Milky Way Monster Black Hole Awakes' is the headline to the story. It apparently fired a monster flare some 300 years ago (yes, just 300 years ago). An X-ray image of the centre of the Milky Way is dominated by Sagittaurus A, a massive black hole or chaotic region where young stars are surrounded by a layer of superheated gas visible only by X-ray imaging.

anti-matter lightning

Daily Galaxy March 8th ... anti-matter lightning has been discovered annihilating bits of earth's atmosphere, it is alleged. The Fermi Gamma Ray Space Telescope was launched to examine the universe and research gamma ray bursts of energy from black holes - as well as the mystery of dark matter. Strangely, they say, they found blasts coming from behind the spacecraft - from earth.

The case for significant numbers of extraterrestrial impacts through the late Holocene

George Howard, on his web site has posted this 2007 article as it appears to tie in with the latest offering from Bill Napier. 'The case for significant numbers of extraterrestrial impacts through the late Holocene' by Mike Baillie (a speaker at several SIS meetings and events). It can be downloaded in pdf format from the web site - see menu on LH side.

Utah in Space March 4th ... planetary scientists have been puzzled for years about the honeycomb patterns and flat valleys with squiggly edges evident from radar images of Saturn's moon, Titan. Now, it is recognised, the terrain is very similar to that of karst topography on earth - in Utah for example, or China and Indonesia (Cassini spacecraft data).
