Cyberalan. SCIENCES & TECHNOLOGIES. 'Zombie' stars key to measuring dark energy. "Zombie" stars that explode like bombs as they die, only to revive by sucking matter out of other stars.
According to an astrophysicist at UC Santa Barbara, this isn't the plot for the latest 3D blockbuster movie. Instead, it's something that happens every day in the universe - something that can be used to measure dark energy. This special category of stars, known as Type Ia supernovae, help to probe the mystery of dark energy, which scientists believe is related to the expansion of the universe. Andy Howell, adjunct professor of physics at UCSB and staff scientist at Las Cumbres Observatory Global Telescope (LCOGT), wrote a review article about this topic, published recently in Nature Communications. LCOGT, a privately funded global network of telescopes, works closely with UCSB. Integral challenges physics beyond Einstein. ESA's Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein.
It has shown that any underlying quantum 'graininess' of space must be at much smaller scales than previously predicted. Einstein's General Theory of Relativity describes the properties of gravity and assumes that space is a smooth, continuous fabric. Yet quantum theory suggests that space should be grainy at the smallest scales, like sand on a beach. One of the great concerns of modern physics is to marry these two concepts into a single theory of quantum gravity. Stuff. Blog » Clarity on the true cost of electricity. The question of electricity cost is tricky. Most of us know oil prices go up and down – and are currently at record highs – which in turn affects the power price. And we know that not only to the costs of importing such fuels change constantly, they also – unlike renewables – produce carbon, which has to be paid for.
But while more and more people are saying onshore wind energy is at “competitive” price levels, others still insist that renewables are expensive and impractical. In order to clear up the issue , EWEA has developed an online tool that instantly calculates electricity costs, including any fuel and carbon risks, for five different technologies – gas, coal, nuclear, onshore and offshore wind. The users are free to type in their own assumptions on, for example, coal and gas prices, future carbon costs, capital cost and availability.
Studying solar wind. NASA's Genesis mission crash-landed back on Earth in 2004.
The spacecraft spent more than two years in orbit around the sun collecting solar wind, which consists of charged particles, on various ultra-pure collector materials. Fortunately, the collector with the greatest scientific value survived the crash almost intact. NASA's Spitzer Finds Distant Galaxies Grazed on Gas. Galaxies once thought of as voracious tigers are more like grazing cows, according to a new study using NASA's Spitzer Space Telescope.
Astronomers have discovered that galaxies in the distant, early universe continuously ingested their star-making fuel over long periods of time. This goes against previous theories that the galaxies devoured their fuel in quick bursts after run-ins with other galaxies. "Our study shows the merging of massive galaxies was not the dominant method of galaxy growth in the distant universe," said Ranga-Ram Chary of NASA's Spitzer Science Center at the California Institute of Technology in Pasadena, Calif. 'Odd Couple' Binary Makes Dual Gamma-ray Flares. In December 2010, a pair of mismatched stars in the southern constellation Crux whisked past each other at a distance closer than Venus orbits the sun.
The system possesses a so-far unique blend of a hot and massive star with a compact fast-spinning pulsar. Volunteer Star Gazers Needed for NASA Mission. Calling all amateur star gazers: Scientists need your help.
A team from Southern Illinois University in Edwardsville has developed the website IceHunters, which challenges the public to discover potential destinations for a NASA mission at the very edge of the solar system set to happen around 2015. "I think it's a great idea," said Yanga Fernandez, a University of Central Florida physics assistant professor and comet expert. "Actually that's kind of how I started. When I was 10, I used to search the sky for interesting objects with my dad. Bright galaxy sheds light on early Universe. Astronomers said on Wednesday they had snared light from a bright, ancient galaxy with a super-massive black hole at its core, a finding that would help explain aspects of the young Universe.
The phenomenon is called a quasar, which are very bright but very distant galaxies with a mighty black hole at their heart. Until now, the most distant quasar ever seen sent light 870 million years after the Big Bang, which is believed to have occurred nearly 13.7 billion years ago. Most Distant Quasar Found. A team of European astronomers has used ESO's Very Large Telescope and a host of other telescopes to discover and study the most distant quasar found to date.
This brilliant beacon, powered by a black hole with a mass two billion times that of the Sun, is by far the brightest object yet discovered in the early Universe. The results will appear in the 30 June 2011 issue of the journal Nature. "This quasar is a vital probe of the early Universe. It is a very rare object that will help us to understand how supermassive black holes grew a few hundred million years after the Big Bang," says Stephen Warren, the study's team leader. Quasars are very bright, distant galaxies that are believed to be powered by supermassive black holes at their centres.

Radio telescopes capture best-ever snapshot of black hole jets. An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.
NEO- Near Earth Objects. Rogue Alien Planets Could Host Extraterrestrial Life. Interstellar planets — those without stars to orbit — could serve as havens for life, according to a new study. They are often thought to be nearly invisible, since they are much dimmer than stars and do not have any suns nearby to illuminate them. Now, however, research suggests these worlds might be detected by their auroras. Can WISE Find the Hypothetical 'Tyche'? Can WISE Find the Hypothetical 'Tyche'? Background In November 2010, the scientific journal Icarus published a paper by astrophysicists John Matese and Daniel Whitmire, who proposed the existence of a binary companion to our sun, larger than Jupiter, in the long-hypothesized "Oort cloud" -- a faraway repository of small icy bodies at the edge of our solar system.
The researchers use the name "Tyche" for the hypothetical planet. Their paper argues that evidence for the planet would have been recorded by the Wide-field Infrared Survey Explorer (WISE). WISE is a NASA mission, launched in December 2009, which scanned the entire celestial sky at four infrared wavelengths about 1.5 times. Following its successful survey, WISE was put into hibernation in February 2011. Frequently Asked Questions.

As we now are discussing the Gregorian Calendar that involves Pope Gregory XIII, i must mention that he may have not known the philosophy of the astronomers/astrologers that he consulted in calcalating the calendar, i wish not to offend Catholics, and we have to note we are dealing with over 400 years ago, when many thought the Earth was flat, it was a world of alchemists, the forerunner to chemistry, and was a time when the church struggled with many new philosphies.
Looking back from today, it is often assumed that even in that period that Christianity and astrology were rival beliefs, an assumption held by many modern Christians, who are generally opposed to astrology on the basis of the criticism of astrologers in the Book of Isaiah, chapter 47, verses 13-14.
