Arecibo message - Wikipedia, the free encyclopedia
This is the message with color added to highlight its separate parts. The actual binary transmission carried no color information. The Arecibo message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope on 16 November 1974. [ 1 ] It was aimed at the globular star cluster M13 some 25,000 light years away because M13 was a large and close collection of stars that was available in the sky at the time and place of the ceremony. [ 2 ] The message consisted of 1679 binary digits , approximately 210 bytes , transmitted at a frequency of 2380 MHz and modulated by shifting the frequency by 10 Hz, with a power of 1000 kW . The "ones" and "zeros" were transmitted by frequency shifting at the rate of 10 bits per second.
SETI Institute Teams with Zooniverse to Launch SETILive.org to Empower Citizen Scientists As part of the TED Prize Wish made by renowned astronomer Jill Tarter, the TED Prize today launches SETI Live (setilive.org): a site where – for the first time – the public can view data being collected by radio telescopes and collectively help search for intelligent life on other planets. 2012 application is open now. Are you looking for a contemporary thematic science curriculum that is standards based? Are you in search of an exciting professional development opportunity? If so, we invite you to become an ASSET teacher.

In theory, Star Trek-style warp drives are possible – but they could come with a bit of a downside. Illustration: Ben Gilliland In the 20th and 21st centuries, when people wanted to traverse the country in comfort and style they took their trusty VW Camper van. Powered by a 1.6-litre air-cooled engine, the vehicle transported its occupants from London to Cornwall in a matter of hours.
Whenever someone proposes to do something that has never been done before, there will always be skeptics. So when I started SpaceX, it was not surprising when people said we wouldn’t succeed. But now that we’ve successfully proven Falcon 1, Falcon 9 and Dragon, there’s been a steady stream of misinformation and doubt expressed about SpaceX’s actual launch costs and prices.

2 Planets Share the Same Orbit
Buried in the flood of data from the Kepler telescope is a planetary system unlike any seen before. Two of its apparent planets share the same orbit around their star. If the discovery is confirmed, it would bolster a theory that Earth once shared its orbit with a Mars-sized body that later crashed into it, resulting in the moon's formation. The two planets are part of a four-planet system dubbed KOI-730.Giant Impact Hypothesis
Artist's depiction of a collision between two planetary bodies. Such an impact between the Earth and a Mars-sized object likely formed the Moon. The giant impact hypothesis states that the Moon was formed out of the debris left over from a collision between the Earth and a Mars -sized body , sometime around 4.5 Ga (four and a half billion years ago). The colliding body is sometimes called Theia , for the mythical Greek Titan who was the mother of Selene , the goddess of the moon. [ 1 ] [ 2 ]
However, 100 kilometers is an awful long way up, so shortly into its 80-second burn, SpaceShipOne climbed above the angle of the sun into clear blue sky. We didn't realize it at the time, but there were a couple of serious malfunctions as the craft accelerated to more than Mach 2.9 (2150 mph or 3460 km/h). About 7 seconds after ignition, a 60 knot (70 mph or 110 km/h) wind shear caused an unintended 90 degree rotation, which the pilot corrected. Just 10 seconds after starting its climb it reached Mach 1, and the rocket continued burning for another 66 seconds before automatically shutting down. Late during this powered phase, one of the motors which control the trim adjustment malfunctioned and although Melvill quickly swapped to a backup system the ship wasn't quite at the right angle as it climbed. The combined anomalies put it 20 miles off course and ultimately cost about 30,000 feet of altitude.

Brief Answers to Cosmic Questions
But I heard that our Milky Way galaxy may one day collide with a neighboring galaxy. If galaxies are all moving apart from each other, how can they collide? Galaxies extend as far as we can detect... with no sign of diminishing.There is no evidence that the universe has an edge. The part of the universe we can observe from Earth is filled more or less uniformly with galaxies extending in every direction as far as we can see - more than 10 billion light-years, or about 6 billion trillion miles. We know that the galaxies must extend much further than we can see, but we do not know whether the universe is infinite or not. When astronomers sometimes refer (carelessly!)
