Do you know what a Pulsar is?

28. january 2008, by joskirps

Pulsar Neutron StarA Pulsar is a "pulsating star", a highly magnetized neutron star that is rotating so fast that it emits a beam of radio, X-ray and/or gamma ray waves. Jocelyn Bell Burnell and Antony Hewish were the first to detect a Pulsar in 1967, and as they initially couldn't explain the regular radio waves they named it "LGM-1", for "Little Green Men" as one could think the radio waves had been emitted by extraterrestrials.In 1968 Thomas Gold and Franco Pacini suggested that Pulsars could be rotating Neutron stars, which turned out to be true. Neutron stars are rather small, but very dense objects, which allows them to rotate rather quickly. Observed Pulsar periods range from 1. 5 ms to 8. 5 s. In 1982, Shri Kulkarni and Don Backer even discovered a Pulsar with a rotation period of only 1. 6 milliseconds.Pulsars are known to have planets orbiting them, and the first ever detected extrasolar planets were found orbiting a pulsar. But it remains unlikely that planets orbiting a Pulsar could allow life forms because of the immense radiation in such a system (although it's also known that life can exist in quite extreme locations, so you never know...)Joseph Taylor and Russell Hulse discovered the first Pulsar in a binary system in 1974, a pulsar which orbits another neutron star with an orbital period of just eight hours.You may also want to check out Pulsar stars in our online galaxy, check out the stars section to learn more!

Traces of ‘Mythical’ Cosmic Strings Found

24. january 2008, by andr0m3da

A controversial new study indicates that there are traces of vast cosmic strings left over in radiation from the early universe. If indeed confirmed to be real, these cosmic strings would offer an unprecedented window into the extreme physics of origins of the universe.The idea is that snags in the fabric of space may have developed a fraction of a second after the universe's birth. This would have likely occurred at the end of the period called inflation when the universe was rapidly expanding.These “snags” are thought to be shaped like very slender strings, with a thickness much less than the width of an atom but with lengths that can be measured in light years. They would also be incredibly heavy. A section just a kilometer long would potentially have as much mass as the entire Earth.Now a team of scientists says there is some valid evidence that these elusive and exotic strings really do exist. They claim that traces of cosmic strings can be detected in the afterglow of the big bang. Neil Bevis of Imperial College London and his team used the Wilkinson Microwave Anisotropy Probe (WMAP) satellite to observe radiation called the cosmic microwave background.This radiation is slightly patchy because of the distribution of the glowing matter that produced it. If present, cosmic strings should attract matter with their gravity, slightly altering the way it is distributed in the early universe.The team of scientists used computers to simulate how the microwave background should look with and without cosmic strings, and compared the results to the WMAP observations. They found a better agreement when cosmic strings were included."This is an exciting result," says Mark Hindmarsh, of the University of Sussex, Brighton, UK, one of the study's authors. "Cosmic strings are relics of the very early universe, and signposts that would help construct a theory of all forces and particles."But there is a 5% chance that the correlation would be produced simply by random noise, and such flukes should be expected from time to time because so many studies of WMAP data are published each year, says Charles Bennett, the chief scientist for the WMAP mission.Future observations should clarify things. The Planck satellite, due to launch in 2008, will make even more sensitive measurements of the microwave background than WMAP, and could turn up better evidence for cosmic strings.

Meteors to Go on the Auction Block

24. january 2008, by dakotastrange

On April 16, Christie's Paris location will have an auction devoted to Natural History. Among the items being offered are meteors of various shapes and sizes. Some described as cut to the richness of metal reflecting like a mirror. The mineral section of the auction will feature the Butterfly of Condor, a unique pinkish agate resulting from manganese oxide, half cut and polished revealing the form of a butterfly wing.Dinosaurs, vertebrates and fossils are the featured items of the event. A Triceratops (late Cretaceous period - 65 to 67 million years ago) bones is expected to highlight the auction. It's four-legged body is 7.5 meters long and bears a large bony frill and three horns. The creature will be familiar to "Jurassic Park" fans. This specimen is described as of the same quality as the famous T. REX called Sue, but this Triceratops does not yet have a name so the future owner will have the honor of naming it.Also included in the sale as reported by artdaily.org are Tiranosauris egg mineralized in agate, a saber-toothed tiger cranium (Homotherium crenatidiens dating to the Miocene Period, a bear cranium of the Pleistocene Superior period, and an Edmontosaurus's, a duck-beaked dinosaur which could reach 13 meters in length, cranium.Christie's website doesn't show that a catalogue is available as yet, but those interested should check the site occasionally.

Great Albert Einstein Quotes (part 1)

24. january 2008, by joskirps

Albert EinsteinAlbert Einstein was a theoretical physicist best known for his theory of relativity and his famous formula E = mc2. He published more than 50 scientific papers and received the Nobel Prize in Physics in 1921. Einstein was Time magazine's "Person of the Century", he is believed to be the greatest physicist of all time and the name "Einstein" has become synonymous with genius.So here's a first set of great Einstein quotes, as I think he often said things that were highly remarkable. Here we go...1. "A person who never made a mistake never tried anything new."2. "I have no special talent. I am only passionately curious."3. "Nationalism is an infantile sickness. It is the measles of the human race."4. "I never think of the future - it comes soon enough."5. "When you sit with a nice girl for two hours, it seems like two minutes. When you sit on a hot stove for two minutes, it seems like two hours that's relativity."6. "I am a deeply religious nonbeliever - this is a somewhat new kind of religion."7. "Gravity cannot be held responsible for people falling in love."8. "You can never solve a problem on the level on which it was created."9. "Once we accept our limits, we go beyond them."10. "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."

The Best Science Fiction Movies Ever Made

23. january 2008, by joskirps

Today I'd like to present a list of the best Science Fiction movies ever made. It's my personal selection, and it only includes space and alien related movies (that's why you won't find movies like Bladerunner or The Matrix and this list). Ready? So here we go (from oldest to newest):1953: War of the Worlds by Byron Haskin. Dr. Clayton Forrester, a world renowned physicist, is on a fishing vacation in the small town of Pine Summit when a giant meteorite lands in the hills above the town. Along with the townsfolk, he goes to investigate, but finds the meteorite too hot to examine immediately. Later, after most people have gone home, the meteorite unscrews and opens, disgorging a Heat-Ray device from Mars.1956: Invasion of the Body Snatchers by Don Siegel. Dr. Miles Bennell, a local doctor, finds a rash of patients accusing their loved ones of being impostors. Bennell soon discovers that the townspeople are in fact being replaced by simulations grown from plantlike pods; perfect physical duplicates who kill and dispose of their human victims.1968: Planet of the Apes by Franklin J. Schaffner. Loosely based on the Planet of the Apes novel by Pierre Boulle, the film was ground breaking for its make-up techniques by artist John Chambers. Astronauts Taylor, Landon, and Dodge are in deep hibernation when their spaceship crash-lands in a lake on an unknown planet in A. D. 3978.1968: 2001: A Space Odyssey by Stanley Kubrick. The film deals with themes of human evolution, technology, artificial intelligence, and extraterrestrial life, and is notable for its scientific realism, pioneering special effects, and provocatively ambiguous imagery and sound in place of traditional narrative techniques. Despite receiving mixed reviews upon release, 2001: A Space Odyssey is today recognized by critics as one of the greatest films ever made.1977: Close Encounters of the Third Kind by Steven Spielberg. It portraits UFO occupants as benign, even kind, which was a sharp departure from the "evil monster" style of most earlier films. It popularized a number of UFO motifs, many of which had earlier been reported in conjunction with UFO sightings, such as alien abduction, small and thin aliens, and UFOs covered in lights rather than the disc shapes popular in the 1950s and 1960s.1977 - 1983: The original Star Wars trilogy by George Lucas, consisting of "A New Hope", "The Empire Strikes Back" and "Return Of The Jedi". It tells the story of Luke Skywalker, a farmer boy who learns the ways of the Jedi and becomes an important figure in the Rebel Alliance, leading the struggle against the Galactic Empire and the evil Darth Vader, who is in fact his father.1979: Alien by Ridley Scott. Reluctantly following a distress beacon in deep space, a crew member of the space-faring towing vehicle Nostromo encounters a young Alien that attacks and infects him. The creature soon comes aboard the ship, wreaking havoc and threatening the entire crew.1982: The Thing by John Carpenter, basically a remake of the 1951 Howard Hawks film "The Thing from Another World". An American Antarctic research station is infiltrated by an alien creature with the ability to perfectly imitate any organic life-form that it physically contacts. The crew of the station come to distrust each other as they cannot discern who is human and who is not. One by one they are killed, either by being transformed into the creature or by each other.1982: E. T.: The Extra-Terrestrial by Steven Spielberg. It tells the story of Elliott, a lonely boy who befriends a friendly alien, dubbed E. T., who is stranded on Earth. Elliott and his siblings help the alien return home while attempting to keep it hidden from their mother and the government.1984: Dune by David Lynch, based on the 1965 Frank Herbert novel. Paul Atreides, a young man who dreams prophetic visions of his purpose, is foretold in a prophecy to be the "Kwisatz Haderach" who will protect the titular desert planet from the malevolent House Harkonnen and save the universe from evil.1997: Starship Troopers by Paul Verhoeven. Loosely based on the novel Starship Troopers by Robert A. Heinlein, Starship Troopers tells the story of an interplanetary war between Earth and colonies of large insect-like aliens in the twenty-third century. It focuses on the experiences of Juan "Johnny" Rico, one of three friends who sign up to the military one year before Earth declares war on the aliens.One movie that didn't fit into a "serious" list but is still worth to be noted is Mars Attacks by Tim Burton, and of course I'd also like to mention the Star Trek series of movies that didn't make it into the list as I think the directing is not that terrible here (but that's a personal opinion of course).
