Life On Mars's Meethane Traces Thought To Be Detected

Life on Mars? Methane has been found in the Martian atmosphere which scientists say could be a sign of present-day life on Mars. It was detected by telescopes on Earth and has recently been confirmed by instruments onboard the European Space Agency's orbiting Mars Express craft. Methane lives for a short time in the Martian atmosphere so it must be being constantly replenished. There are two possible ways to do this. Either active volcanoes, but none have yet been found on Mars, or microbes. The Independent has it as Methane find on Mars may be sign of life. The second group to detect signals of methane in the Martian atmosphere is led by Michael Mumma of Nasa's Goddard Space Flight Centre in Maryland, who used powerful spectroscopic telescopes based on Earth. This team is even believed to have detected variations in the concentrations of methane, with a peak coming from the ancient Martian seabed of Meridiani Planum, which is being explored by a Nasa rover. This could indicate a subterranean source of methane which is pumping out the gas, either due to some residual geological activity or because of the presence of living organisms producing it as a waste gas. Asked whether the continual production of methane is strong evidence of a biological origin of the gas, Dr Mumma said: "I think it is, myself personally." As to how...

Leonid Meteor Storm 2002

They're back--and promise to as brighter or brighter than last year:
NASA scientists' predictions for the 2002 Leonid meteor storm.

Such meteor storms rarely happen in consecutive years, but 2001 and 2002 are exceptions. Experts have just released their predictions: Depending on where you live (Europe and the Americas are favored) Leonid meteor rates in 2002 should equal or exceed 2001 levels.

That's the good news. The bad news is that the Moon will be full when the storm begins on Nov. 19th. Glaring moonlight will completely overwhelm many faint shooting stars. Indeed, I often hear that the Moon is going to "ruin the show."


We shall see.

On Nov. 18, 2001, sky watchers somewhere will see a dazzling storm of Leonid meteors.

On Nov. 18, 2001, sky watchers somewhere will see a dazzling storm of Leonid meteors. And Leonid Observing Tips. It's the rainy season where I live so I'm pessimistic about my chances but maybe some of you have a shot at seeing them. Posted here as a PSA.
