Albert Einstein firmly believed that the universe cannot be chaotic. Every aspect of it, biotic as well as abiotic, exists in harmony. Similar belief led many leading physicists to interpret every universal phenomenon in mathematical terms. It has also been observed that many natural developments occur as per definite mathematical precision.
Monsoon prediction has long been a touchy and sticky issue in India. The Department of Meteorology uses all the internationally approved parameters, as well as cutting edge technology. In spite of this, predictions have been highly inaccurate in recent years. With 70% population living solely on land income, monsoon prediction assumes immense importance in the agricultural life of this country.

Pcfreakske2000 writes: NASA’s Mars Reconnaissance Craft Begins Adjusting Orbit 03.31.06
NASA’s Mars Reconnaissance Orbiter yesterday began a crucial six-month campaign to gradually shrink its orbit into the best geometry for the mission’s science work. Three weeks after successfully entering orbit around Mars, the spacecraft is in a phase called "aerobraking."
This process uses friction with the tenuous upper atmosphere to transform a very elongated 35-hour orbit to the nearly circular two-hour orbit needed for the mission’s science observations.The orbiter has been flying about 426 kilometers (265 miles) above Mars’ surface at the nearest point of each loop since March 10, then swinging more than 43,000 kilometers (27,000 miles) away before heading in again.

Pcfreakske2000 writes: You don’t get much closer to the big bang than this.
Scientists peering back to the oldest light in the universe have evidence to support the concept of inflation, which poses that the universe expanded many trillion times its size faster than a snap of the fingers at the outset of the big bang.
We’re talking about when the universe was less than a trillionth of a trillionth of a second old. In that crucial split second, changes occurred that allowed for the creation of stars and galaxies hundreds of millions of years later.

Stardust Samples Show Evidence of Fire, Ice
Stardust samples of comet particles might seem like a strange place to find a big component of the green sand found on some Hawaiian beaches, but there it was.
The spacecraft, which flew within 150 miles of the comet Wild 2 in January 2004, brought back samples that may provide new insights into the composition of comets and how they vary from one another, scientists said Monday.
Remarkably enough, we have found fire and ice," said Donald Brownlee, Stardust principal investigator and professor of astronomy at the University of Washington in Seattle. The returned samples show high-temperature materials from the coldest part of our solar system.

Rehearsing for the Real Deal Mars plays a mean defense. The red warrior has overwhelmed nearly two-thirds of all international spacecraft that have sought its mysteries.
For NASA's latest encounter with Earth's testy neighbor, the Mars Reconnaissance Orbiter team will be going into battle armored with discipline, training and experience. Until Mars Reconnaissance Orbiter is safely in its final science orbit, it is largely an engineering game. Like any good squad, the engineering team practices before the "big game."
"We want to make sure our team is ready," said mission operations training engineer Ruth Fragoso. "We're trying to pressure the team. We want to see how they respond. We try to get them at their weakest spots." In an exercise with a relatively benign name – operational readiness test – the Mars Reconnaissance Orbiter engineers are put through their paces in an orbit insertion simulation that Fragoso notes is "as flight-like as possible.

Scientists have found evidence that cold, Yellowstone-like geysers of water are issuing from a moon of Saturn called Enceladus, apparently fueled by liquid reservoirs that may lie just tens of yards beneath the moon’s icy surface.
The surprising discovery, detailed in Friday’s issue of the journal Science, could shoot Enceladus to the top of the list in the search for life elsewhere in our solar system. Scientists described it as the most important discovery in planetary science in a quarter-century.
"I think this is important enough that we will see a redirection in the planetary exploration program," Carolyn Porco, head of the imaging team for the Cassini mission to Saturn, told MSNBC.com. "We’ve just brought Enceladus up to the forefront as a major target of astrobiological interest."

Pcfreakske2000 writes: Giant galaxies weren’t assembled in a day. Neither was this Hubble Space Telescope image of the face-on spiral galaxy Messier 101 (M101).
It is the largest and most detailed photo of a spiral galaxy that has ever been released. The galaxy’s portrait is actually composed of 51 individual Hubble exposures, in addition to elements from images from ground-based photos. The final composite image measures a whopping 16,000 by 12,000 pixels.
The Hubble archived observations that went into assembling this image were originally acquired for a range of Hubble projects: determining the expansion rate of the universe, studying the formation of star clusters in the giant star birth regions, finding the stars responsible for intense X-ray emission, and discovering blue supergiant stars.

Anxiously awaited follow-up observations with NASA's Hubble Space Telescope have confirmed the presence of two new moons around the distant planet Pluto.
The moons were first discovered by Hubble in May 2005, but the science team probed even deeper into the Pluto system last week to look for additional satellites and to characterize the orbits of the moons. Though the team had little doubt the moons are real, they were happy to see the moons show up very close to the locations predicted from the earlier Hubble observations. The initial discovery is being reported today in this week’s edition of the British science journal Nature.
The confirmation reinforces the emerging view that the Kuiper Belt, a swarm of icy bodies encircling the solar system beyond Neptune, may be more complex and dynamic than astronomers once thought.

Pcfreakske2000 writes: NASA's Spitzer Space Telescope has identified two huge "hypergiant" stars circled by monstrous disks of what might be planet-forming dust. The findings surprised astronomers because stars as big as these were thought to be inhospitable to planets.
Extremely massive stars are tremendously hot and bright and have very strong winds, making the job of building planets difficult," said Joel Kastner of the Rochester Institute of Technology in New York. "Our data suggest that the planet-forming process may be hardier than previously believed, occurring around even the most massive stars that nature produces."
Kastner is first author of a paper describing the research in the Feb. 10 issue of Astrophysical Journal Letters

Deep down, black holes are filled with the vibrant light of gas trapped inside.
Venturing into the black hole at the center of our galaxy, you'd have a good 20 seconds' worth of viewing time of the radiant wonderland all around you before being vaporized, as you ride on a waterfall of moving space plunging toward the black hole core faster than light itself.
Well, Einstein's math supports such a scenario. And a team of scientists and television producers has turned Einstein’s equations into a new planetarium show called Black Holes: The Other Side of Infinity.
