We have company: Asteroid discovered in Earth’s orbit

The first known Earth Trojan asteroid, "2010 TK7" (represented by the green dots), sits in front of Earth at a gravitational "sweet spot" and poses no danger.

Planet Found With Gravitational Microlensing

The first discovery of a planet around another star using gravitational microlensing was announced yesterday by two research teams: Microlensing Observations in Astrophysics (MOA) and Optical Gravitational Lensing Experiment (OGLE). A First: Planet Found With Gravitational Microlensing.

Solar Storm May Disrupt Soap Operas

SpaceWeather.com writes: EXTREME SOLAR ACTIVITY: One of the most powerful solar flares in years erupted from giant sunspot 486 on Oct. 28th. The blast measured X17 on the Richter scale of solar flares. As a result of the explosion, a strong S3-class solar radiation storm is underway. Click here to learn how such storms can affect our planet. The explosion also hurled a coronal mass ejection (CME) toward Earth. The CME struck Earth's magnetic field on Oct. 29th and sparked an intense geomagnetic storm.

European Space Agency Embarking on Comet-Chasing Mission

Comet-chasing mission Rosetta will now set its sights on Comet Churyumov-Gerasimenko. During its meeting on 13-14th May 2003, ESA's Science Programme Committee decided Rosetta's new mission baseline. The spacecraft will be launched in February 2004 from Kourou, French Guiana, using an Ariane-5 G+ launcher. The rendezvous with the new target comet is expected in November 2014. New destination for Rosetta, Europe's comet chaser

Mars makes its closest pass to Earth since 2,205,000 days ago

...and that's counting 15,000 leap years.

Quintessence = The Key to Antigravity

It would appear that science is discovering quantum mechanical nature to support an expanding universe and as well as antigravity. Let's encourage the next generation quantum engineers to develop personal antigravity limousines (i.e. pals) to jet us past the traffic jams. Accelerating Universe theory dispels dark energy.

Talk About ‘Far Out!’

"FINDING ALIEN MESSAGES... Two University of Hawaii physicists say the reason we're not getting messages or signals from alien civilizations is that such communication is disguised and indistinguishable from background noise. Walter Simmons and Sandip Pakvasa say messages sent by this method could be criss-crossing our galaxy without us ever knowing. If a signal -- a stream of photons -- comes from a single source, its origin can always be determined by measuring the direction of recoil of a detector struck by the photons. The physicists say the way around this is the signaler splits the message into two parts, so photons are sent in opposite directions to mirrors located far from the home planet. The mirrors redirect the signals to the intended receiver, who recombines the photons to reconstruct the message. If the image is tiny enough, Heisenberg's uncertainty principle -- which limits the amount of information that can ever be known about a microscopic particle -- means measuring the position of the photons makes it impossible to gain accurate information about the direction in which they are traveling. It also would be impossible to detect the message at all without extremely sophisticated technology. To recombine the beams and recreate the message you would need to detect the arrival time of the photons extremely accurately to identify pairs of photons split by the sender."
