Total Solar Eclipse

27 07 2008

On Audust, 1 the total solar eclipse will blot out the sun. If you want to learn more about what is an eclipse of the Sun, what causes eclipses and why, how often do eclipses happen and when is the next eclipse of the Sun, You can easely get the answers to these questions online. I just would like to add that this is very rare situation because all parts of thisplanet’s puzzle must be coincided. For a solar eclipse to take place the moon must be in its new phase and passes between the Sun and the Earth so that the Sun is wholly or partially occured.

So, what is in store for us? Here is the Calendar Date Eclipse and Type of Eclipses of the Sun: 2008 - 2015

Large Hadron Collider

8 07 2008

The gigantic scientific instrument called Large Hadron Collider has to be started up today in a world’s largest and most respected centre for scientific research near Geneva at the border Switzerland and France about 100 m underground. This grand scientist experiment will help physicists to learn more about the laws of Nature. What is the result we should expect from such grandioso human’s practical activities on the Earth? There are many theories and discussions about. But the main goal is finding out what the Universe is made of and how it works.

Do you think the answer will be found soon? I don’t so. But no doubt today is the beginning of the process.





ATLAS and CMS

26 06 2008

While the discussion about ATLAS and CMS, general-purpose particle physics experiments is continuing scientists do their work. The ambition project called for help to see a wide range of particles and phenomena produced in LHC collisions has involved approximately 2,000 physicists from some 35 countries.

They will use the data collected from the complex ATLAS and CMS detectors to search for new phenomena, including the Higgs boson, super symmetry and extra dimensions. They will also measure the properties of previously discovered quarks and bosons with unprecedented precision, and be on the lookout for completely new, unpredicted phenomena.

What is Higgs boson? This is “a fundamental particle predicted by theorist Peter Higgs, may be the key to understanding why elementary particles have mass”, Howard E. Haber from University of California, Santa Cruz explanes. “Explaining the connection, I am reminded of the puzzler, “If sound cannot travel in a vacuum, why are vacuum cleaners so noisy?” This riddle actually touches on a profound insight of modern physics: the vacuum—or empty space—is far from empty. It is indeed “noisy” and full of virtual particles and force fields. The origin of mass seems to be related to this phenomenon.
In Einstein’s theory of relativity, there is a crucial difference between massless and massive particles: All massless particles must travel at the speed of light, whereas massive particles can never attain this ultimate speed. But, how do massive particles arise? Higgs proposed that the vacuum contains an omnipresent field that can slow down some (otherwise massless) elementary particles—like a vat of molasses slowing down a high-speed bullet. Such particles would behave like massive particles traveling at less than light speed. Other particles—such as the photons of light—are immune to the field: they do not slow down and remain massless.

Although the Higgs field is not directly measurable, accelerators can excite this field and “shake loose” detectable particles called Higgs bosons. So far, experiments using the world’s most powerful accelerators have not observed any Higgs bosons, but indirect experimental evidence suggests that particle physicists are poised for a profound discovery.”





Phoenix Landed on Mars.

26 05 2008

Phoenix spacecraft landed in the northern polar region of Mars on May 25, 2008 to begin three months of examining a site chosen for its likelihood of having frozen water within reach of the lander’s robotic arm, NASAreports.

Radio signals received at 4:53:44 p.m. Pacific Time (7:53:44 p.m. Eastern Time) confirmed the Phoenix Mars Lander had survived its difficult final descent and touchdown 15 minutes earlier. The signals took that long to travel from Mars to Earth at the speed of light.

Mission team members at NASA’s Jet Propulsion Laboratory, Pasadena, Calif.; Lockheed Martin Space Systems, Denver; and the University of Arizona, Tucson, cheered confirmation of the landing and eagerly awaited further information from Phoenix later tonight.





Mars Rover program is Continuing.

26 03 2008

On Monday we’ve head that scientists plan to put one of the twin Mars rovers to sleep and limit the activities of the other robot to fulfill a NASA because their budget was being cut by $4 million.

But on the next day NASA says that it has absolutely no plan to turn off either of the Mars Rovers because of budget cuts. It has rescinded a letter that recommended budget cuts in the Mars Rover program to cover the cost of a next-generation rover on the Red Planet.


(this is Mars, general view )

The agency’s administrator, Michael D. Griffin, says NASA needs the money to keep the space shuttle fleet aloft, complete the International Space Station and build a new crew exploration vehicle to replace the shuttle and but as was saying in a statement Tuesday neither of the rovers will be shut down.





Unexpected Anomalies.

1 03 2008

Mysteriously, five spacecraft that flew past the Earth have each displayed unexpected anomalies in their motions, SPACE.com reports. In five of the six flybys, the scientists have confirmed anomalies.

“I am feeling both humble and perplexed by this,” said Anderson, who is now working as a retiree. “There is something very strange going on with spacecraft motions. We have no convincing explanation for either the Pioneer anomaly or the flyby anomaly.”

In the one probe the researchers did not confirm a noticeable anomaly with, MESSENGER, the spacecraft approached the Earth at about latitude 31 degrees north and receded from the Earth at about latitude 32 degrees south. “This near-perfect symmetry about the equator seemed to result in a very small velocity change, in contrast to the five other flybys,” Anderson explained — so small no anomaly could be confirmed.

The five other flybys involved flights whose incoming and outgoing trajectories were asymmetrical with each other in terms of their orientation with Earth’s equator. The fact this effect seems most evident with flybys most asymmetrical with respect to Earth’s equator “suggests that the anomaly is related to Earth’s rotation,” Anderson said.

As to whether these new anomalies are linked with the Pioneer anomaly, “I would be very surprised if we have discovered two independent spacecraft anomalies,” Anderson told SPACE.com. “I suspect they are connected, but I really do not know.”

“Another thing in common between the Pioneer and these flybys is what you would call an unbound orbit around a central body,” Anderson said. “For instance, the Pioneers are flying out of the solar system — they’re not bound to their central body, the sun. For the other flybys, the Earth is the central body. These kinds of orbits just don’t occur very often in nature — it could be when you get into an unbound orbit around a central body, something goes on that’s not in our standard models.”

The researchers are now collaborating with German colleagues to search for possible anomalies in the Rosetta probe’s second flyby of the Earth on November 13.

“We should continue to monitor spacecraft during Earth flybys. We should look carefully at newly recovered Pioneer data for more evidence of the Pioneer anomaly,” Anderson added. “We should think about launching a dedicated mission on an escape trajectory from the solar system, just to look for anomalies in its motion.”





Do We Have a Future?

5 02 2008

Recent scientific researches argued that a new epoch in the planet’s geologic history has begun. It seams that we have to say goodbye to the 10,000-year-old Holocene Epoch and hello to the Anthropocene. Our world is in trouble.
Among the major changes heralding this two-century-old man-made epoch:
Vastly altered sediment erosion and deposition patterns.
Major disturbances to the carbon cycle and global temperature.
Wholesale changes in biology, from altered flowering times to new migration patterns.
Acidification of the ocean, which threatens tiny marine life that forms the bottom of the food chain.
In the February issue of the journal GSA Today, a publication of the Geological Society of America, Jan Zalasiewicz and Mark Williams of the University of Leicester and colleagues at the Geological Society of London argue that industrialization has wrought changes that usher in a new epoch, livescience.com. reports. Scientists of the future will have no trouble deciding if the proposal was timely. All they’ll need to do is dig into the planet and examine its stratigraphic layers, which reveal a chronology of the changing conditions that existed as each layer is created. Layers can reflect volcanic upheaval, ice ages or mass extinctions.
“Sufficient evidence has emerged of stratigraphically significant change (both elapsed and imminent) for recognition of the Anthropocene — currently a vivid yet informal metaphor of global environmental change — as a new geological epoch to be considered for formalization by international discussion,” Zalasiewicz’s team writes.
Up to half of Earth’s land has been transformed by human activity, wrote Crutzen and Eugene F. Stoermer of the University of Michigan. They also noted the dramatic increase in greenhouse gases and other chemicals and pollutants humans have introduced into global ecosystems.
As early as the late 1800s scientists were writing about man’s wholesale impact on the planet and the possibility of an “anthropozoic era” having begun, according to Crutzen, who is credited with coining the term Anthropocene (anthropo = human; cene = new) back in 2000. That year, Crutzen and a colleague wrote in the scientific newsletter International Geosphere-Biosphere Programme about some of the dramatic changes:
“Urbanization has … increased tenfold in the past century. In a few generations mankind is exhausting the fossil fuels that were generated over several hundred million years.”
Up to half of Earth’s land has been transformed by human activity, wrote Crutzen and Eugene F. Stoermer of the University of Michigan. They also noted the dramatic increase in greenhouse gases and other chemicals and pollutants humans have introduced into global ecosystems.
The epochal idea has merit, according to geologist Richard Alley of Pennsylvania State University.
“In land, water, air, ice, and ecosystems, the human impact is clear, large, and growing,”Alley told ScienceNow, an online publication of the American Association for the Advancement of Science. “A geologist from the far distant future almost surely would draw a new line, and begin using a new name, where and when our impacts show up.”

Calling things by their right the main and only cause of dramatic change is a critical mass of humanity that influences change at a global scale. What is the solution?





Astronomical Events 2008.

26 01 2008

Don’t be asleep at the early morning of Friday, February 1, 2008. It will be the time when Venus, the closest planet to Earth, and Jupiter, the largest planet in the solar system, appear the closest together in the night sky, dont miss it The most spectacular celestial sights over the next couple of weeks are reserved for the early morning sky. Two bright planets will converge, and then be joined by the moon, SPACE.com reports.

For the past several months, dazzling Venus has been prominent in our morning sky. And about a week ago, Jupiter also began to emerge from out of the glare of the Sun. The two planets are currently rising out of the east-southeast horizon about two hours before sunrise.

At last quarter (half) phase on Jan. 30, the moon will stand alone, high toward the south at sunrise. Early on Sunday morning, Feb. 3, the moon will sit well off to the west (right) of the planets. Monday, Feb. 4, the show will reach its peak when, about 45 minutes before sunrise, Venus, Jupiter and the moon — the three brightest objects of the night sky — will form a striking isosceles triangle, with the two planets 3 degrees apart and the moon marking the vertex of the triangle just over 5 degrees below the “dynamic duo.”

By the way, what else is expected us in 2008?
February, 21 will be total lunar eclipse,
August, 1 we will have chance to watch total solar eclipse,
August 16, will be partial Moon eclipse,
December, 1 Venus Jupiter and Mercury will be joined ,
December, 31 will be joining Mercury and Jupiter.
That’s all.





Meteorite in Peru.

19 09 2007

This afternoon scientists which went to the town of Carancas in the Region of Puno, Peru, have confirmed that the glowing object which fell from the sky on Saturday afternoon was indeed a meteorite. Health Directorate reported that doctors and nurses found it necessary to establish auxiliary medical tents near the health center in Carancas because at least 150 people had been seen after having stated they had dermal injuries, were dizzy, nauseous or vomiting and at least seven police officers were affected after they collected samples from the landing site of what is thought to be meteorite.

Scientists confirmed that the meteorite that caused a 17 meter (55 foot) wide and 5 meter (16 foot) deep crater in Puno, Peru was a chondrite meteorite. The water in the crater is to be drained and several teams of scientists from different countries will take samples from the crater itself and from surrounding areas. We just have to wait for the scientists inal decision what it was exactly.





Hurricane Dean

20 08 2007

NACA reports that at 06:56 CDT, shuttle Endeavour undocked from ISS, officially ending the joint operations phase of STS-118.

It was a successful mission from the ISS standpoint.
The $11 million, 11′x14′x15′ S5 truss segment was installed on the ISS main truss.
[EVA] Replacement of an ISS gyroscope.
4 EVAs performed.
A 7500 lb external stowage platform was installed on the ISS main truss.
~2 tons of cargo (food, clothing, and hardware) was transferred from Endeavour to ISS.

Hurricane Dean is now tracking well south of Houston, and barely going to touch TX. So its unlikely MCC-Houston will have to evacuate. That’s good news.

Attached some photos of Hurricane Dean, taken by the ISS crew. To give you an idea of the size of Dean, its approximately 650 miles across. For reference, the storm would almost completely cover the states of Colorado, Arizona, New Mexico, and Utah.
