Star Count May Triple

Star count may triple, according to articles in ScienceDaily and Nature 1 December 2010. Astronomers have been studying nearby elliptical galaxies using the Keck Observatory, Hawaii, to look for signs of red dwarfs. These are small dim stars that up until now, astronomers had not detected in other galaxies. They found there are about 20 […]

Soaking Wet Mars

“Soaking wet” Mars excites scientists, according to BBC news, Nature Science Update and press releases from the Mars Exploration Rover Mission, 2, 5 & 18 March 2004. Rock formations at both sites currently being explored by robots on Mars appear to have the right physical structure and chemistry for being formed in wet conditions. Some […]

Sharp Edge Ring Mystery

Sharp edge ring mystery reported in New Scientist 10 July 2004, p10. Photos from the Cassini probe, currently exploring Saturn and its rings, have revealed “a host of ringlets with unexpected sharp edges – a mystery, as collisions (over billions of years) between the particles should smooth out the edges.” Editorial Comment: The solution to […]

Sand, Not Water, Flowed on Mars

Sand, not water, flowed on Mars, suggests an article in Nature Science Update, 25 May 2004. Four years ago the Mars Global Surveyor (a spacecraft orbiting Mars) took photos of formations resembling recently dried up river beds. These led scientists to suggest they were formed by water venting from underground reservoirs. However, Troy Shinbot and […]

Salt Water Flows on Mars

Salt water flows on Mars, suggest scientists in reports from ScienceNOW and NASA Science News 4 August 2011. Scientists analysing images from the Mars Reconnaissance Orbiter, a satellite orbiting Mars, have found over a thousand dark streaks that seem to grow and shrink with the passing seasons. The streaks are on the facing slopes on […]

Radical Planet Rings

Radical planet rings baffle space scientists, according to an article in ScienceNOW, 6 September 2005. Scientists analysing images and information gathered from the Cassini space craft currently exploring Saturn are having a difficult time interpreting the results. One ring, the D ring, has become 10 times dimmer and moved 200 km closer to the planet […]

Quote: John Eddy on Time

‘I suspect…that the Sun is 4.5 billion years old. However, given some new and unexpected results to the contrary, and some time for frantic readjustment, I suspect that we could live with Bishop Ussher’s value for the age of the Earth and Sun (approx 6,000 years). I don’t think we have much in the way […]
