Scientists have announced the discovery of a superdense star spinning at more than 60 time per second, and calculated that it could have been spinning as fast as 150 times per second or more when it formed some 4,000 years ago. Most astronomers had not perviously believed this class of …
The universe has reached escape velocity. It did so about 15 billion years ago, give or take a few billion. Most will not feel the practical consequences for another 100 billion years or so, but for those of them who are theoretical cosmologists, the matter is rather more urgent. The …
Two new chemical studies have produced evidence that significant amounts of the organic compounds in a Martian meteorite found in Antartica are terrestrial contamination not possible traces of past life on Mars. Scientists conducting the research said the findings dealt a severe blow to the contention that the potato size …
Pictures taken by the Hubble Space telescope support the view that a new planet has been created by debris cast off by the star Beta Pictoris about 61 light years from earth.
A blackhole with the mass of nearly 2.6 million Suns lies at the heart of our Milky Way galaxy with a seductive force that sends stars close to it speeding by at 965 kmph, astronomers reported on Wednesday.Elsewhere in the galaxy, the astronomers told of a kind of "Old Faithful" …
Nasa headed back to the moon for the first time in 25 years on Tuesday night, launching an orbiting spacecraft to look for water that could one day be used by human settlers.
One of the Milky Way Galaxy's largest stars may in fact be a double star system, according to recent research by a team of astronomers using NASA's Rossi X-ray Timing Explorer (RXTE) spacecraft.
Scientists observing a disk of matter surronding a black hole in our galaxy have discovered that the disk is periodically disrupted and hurled outward in opposite directions from the black hole, in jets moving at nearly the speed of light. The black hole replenishes the disk by pulling hot gas …
Nasa's return to the moon after being away for 25 years will have to wait at least another day. An unmanned Athena rocket was supposed to blast off with the lunar prospector spacecraft by the light of a first moon on Monday night. But last-minute trouble with the Air Force …
Twenty five years after the last Apollo astronaut left the moon, a small unmanned spacecraft is ready to embark on a return trip, the first mission since then designed expressly for lunar exploration. One of its priorities is to answer the question, is there water on the moon ? The …
With its cash-strapped economy, Russia is practically giving away its secrets. The country's once vaunted space program is so hard up it's selling its know how to the United States at bargain-basement prices. NASA officials say the agency will spend $400,000 next year for planetary research from Russia's best and …
you might have played several guitars , but plucking the strings of this guitar may not be easy. Harold Craighead and Dustin Carr at the Cornell University, usa , have developed the world's smallest guitar that is nearly hundredth of a millimetre long. By inventing the guitar, the researchers wanted …
the atmospheres of giant planets are mostly made-up of hydrogen, helium and methane. Now, studies at the Infrared Space Observatory ( iso ) Science Operation, Villafranca, Spain, show that the icy satellites and the rings which surround these planets, could be an important source of oxygen to the atmospheres of …
the number of transistors in a single chip has been growing steadily for many years. Simultaneously, the size of transistors has been shrinking at a faster rate. Most researchers believe that after a certain point, the shrinking of transistors size would stop as there is a lower limit for the …
a rhythm in the ebb of sunspot dominates the atmosphere of the Sun and influences life on the Earth as well. Some of the largest sunspots can be even seen without a telescope. Recently, C Westendorp and his colleagues at the Instituto de Astrofisica de Canarias, Tenerife, Spain, claim to …
A vast halo of gamma rays surrounds the Milky Way galaxy, say scientists. Gamma rays are particles of light that contain highest levels of energy of all forms of radiation. Dave Dixon and his colleagues at the University of California-Riverside, USA, say that the presence of gamma rays indicates that …
Researchers may soon be able to solve the mystery of why the outermost regions of the Sun are so hot. The visible surface of the Sun has a temperature of nearly 6000
Electric charges are known to come in integral multiples of the smallest charge called electron. But in certain cases, these charges are also found in fractional units. Scientists in Israel and France have separately confirmed the quantum Hall effect. According to the law, when electrons are restricted to flow in …
That romantic glow it sheds on lovers is apparently not the only atmosphere the moon provides. The moon turns out to have a thin atmosphere, and a team of German and American scientists is launching an effort to find out what it consists of .
