Student Engineers Spark Zero-Gravity Fires on Weightless Wild Ride

Gravity, we have defied you. Seven university student teams from across the United States escaped the pull of Earth's gravity — if only for a few seconds — on a NASA microgravity flight to see how fire, liquids and magnets behave in weightlessness.

The students flew with NASA's Microgravity University Program Friday (July 19) aboard a Zero Gravity Corporation Boeing 727 jet modified to fly up and down on a parabolic path to create up to 30 seconds of zero gravity, moon gravity or Martian gravity on the downswing followed by periods of "hypergravity" (twice Earth's pull) on the way back up.

How to Survive a Lightning Strike

There's a club open to people from all around the world, but you wouldn't want to join: The club is exclusively for people who've survived a lightning strike.

Rare Particle Discovery Dims Hopes for Exotic Theories

Physicists have measured an extremely rare particle decay inside the world's largest atom smasher — a discovery that bolsters the leading model of particle physics and leaves little room for undiscovered particles beyond this theory.

Curiosity Rover Samples Air for a Taste of Mars History

It’s time to update the list of ingredients in Martian air.

In late 2012 NASA’s Curiosity rover drew air into its onboard laboratory and analyzed Mars’s atmospheric composition with a pair of spectrometers. The results of the investigation, published July 19 in Science, revise decades-old data on the makeup of Red Planet air and paint a broad picture of how the atmosphere has changed since the planet’s formation.

Physicists unveil results helping explain the universe

After a quarter-century of searching, scientists have nailed down how one particularly rare subatomic particle decays into something else — a discovery that adds certainty to our thinking about how the universe began and keeps running.

The world's top particle physics lab said Friday it had measured the decay time of a particle known as a Bs (B sub s) meson into two other fundamental particles called muons, 

The planets orbiting cooler stars have a warm climate

There is an assumption that the planets orbiting the cold star may not be on the surface of snow or ice, in contrast to those that rotate around hot. This is possible due to the interaction of starlight with ice and snow on the surface of the planets.

NASA selected the advanced technological concepts for further development

NASA has selected 12 proposals, including two from the Jet Propulsion Laboratory in Pasadena (of California), for the study of the first phase of the Subsidiary Innovative Concepts (NIAC). The program focuses on a detailed study and elaboration of existing concepts without specific algorithm they use to humans. Thus, through this process, it is planned to make a series of scientific fantasies into reality.

Hubble telescope has found the impossible planet

Scientists are puzzled by the new discovery that could make using the space telescope Hubble. They found outside our solar system planet, the conditions of origin of which modern science can not yet explain. The report is published on the website of the Institute Space Telescope. Cosmic body surprising origin was discovered during monitoring situated at a distance of 176 light-years from Earth, the star TW Hydra. Heavenly body, which exoplanet, is removed from the star is 12 billion kilometers, reports the publication .

Suspended a spacewalk after finding fluid in the spacesuit

"The decision to suspend the walk, as European astronaut Luca appeared Parmitano water in diving," said Solovyov told Interfax.

The "fluid leakage" occurred when Parmitano and NASA astronaut Chris Cassidy performing repair and maintenance tasks outside the orbital outpost.

"After that the U.S. took the decision on the urgent return of the astronauts aboard the ISS," said Anna Vedisheva, spokesman for the Russian space agency Roscosmos.

Solving a mystery than 3,500 million years

Scientists cannot know for sure if there is life in space outside the Earth, but new research by a team of scientists led by an astrobiologist at the University of South Florida (USF) shows that one of the key elements that produced life on Earth was brought to Earth by meteorites.

In an article published in the Proceedings of the National Academies of Sciences, 

NASA Moon Probe Helps Pin Down Off-Planet Driving Record

A 1970s Soviet rover did indeed travel about 3 miles farther on the surface of the moon than originally thought, meaning that any robot hoping to break its off-world distance record will have to run a full marathon, researchers say.

The remote-controlled Lunokhod 2 moon rover was long thought to have traveled 23 miles (37 kilometers) on the lunar surface back in 1973. But a Russian team recently upped the estimate to 26 miles (42 kilometers), using images snapped by NASA's sharp-eyed Lunar Reconnaissance Orbiter.

5 scientific theories about what aliens might look like Jellyfish? Bugs? Or just like you?

We've seen them portrayed in a vast variety of Hollywood films, from the nasty, slimy suckers shown in Independence Day to the precious, teddy-bear-esque creature that charmed us in E.T. But which is closer to the truth? As our understanding of the universe grows and the outlook on our existence is in turn humbled, scientists are beginning to theorize what these extraterrestrials might look like. 

The Sombrero Galaxy is seen by the Hale

What happens in the center of this spiral galaxy? Call Sombrero Galaxy for its resemblance to the Mexican sombrero, M104 has a very striking dust lane and bright halo consisting of stars and clusters globular. 

The diffuse glow of the extended core of the galaxy is due to the brilliance of billions of old stars. 

Colorful imaged the death of a planetary nebula

The NASA has achieved through his telescope Chandra grasping the end of a star's life, namely NGC 2393, known as "Eskimo Nebula". This study allows astronomers to predict the demise of the Sun, expected within about 5,000 million years.

Planetary nebulae like this are formed when a star consumes all the hydrogen in its core, something will happen to our sun in about 5,000 million years, reports NASA. At the time this happens, 

The first exoplanet that around a solar-type star

That blue dot in the upper right is Gliese 504b (GJ 504b), a giant planet that is 59 light years from Earth orbiting a solar-type star. But what is this special? Have we not already seen several extrasolar planets directly? Yes, but doing a little cheating. And is that exoplanets we have seen directly, as the system HR 8799, for example-are actually training worlds still shine with their own light, especially in infrared.

Large sunspot group

In the Academy of Sciences astro photographers circle he was not previously active, even more warmly now our "Welcome". On 7 July this year, he managed the mosaic of an interesting area to a large sunspot group (AR 1785). He used a Meade Refractor (ED 152 mm with 3x Barlow lens) and as a DMK camera 21AU618.AS. At 3657 mm effective focal length (aperture 24) the frames of the video sequence were exposed to 0.2 ms. 

The Great Wall of China is not can be seen from space

One of the most popular spatial myths is that the Great Wall is the only man that can be seen from space. Well, not true. The reality is you cannot easily see the Great Wall from low Earth orbit to the naked eye. And rightly the Apollo astronauts could not see it from the moon, despite the urban legend has spread widely.

Sun's 2013 Solar Activity Peak Is Weakest in 100 Years

Though the sun is currently in the peak year of its 11-year solar weather cycle, our closest star has been rather quiet over all, scientists say.

This year's solar maximum is shaping up to be the weakest in 100 years and the next one could be even more quiescent, scientists said Thursday (July 11).

SUNNY TAIL: 3D quatrefoil

In the solar system is the tail of the solar wind particles, resembling the tail of a comet. To verify the existence of this tail, and determine its structure, scientists were able, after analyzing data collected over three years, the spacecraft NASA IBEX.

Moon Has Close Encounters with Planets, Star This Month: How to See It

If you only glance at the sky now and then, you may think it's pretty much the same every night. Regular sky watchers know better, and are aware of the constant changes the sky undergoes.

Take the moon, for example. Although most people know that the moon revolves around the Earth, they may never have noticed this movement with their own eyes. This week we get a chance to do exactly that.

Student Team Set for Zero-Gravity Fire Experiment on NASA 'Vomit Comet'

A team of university students is counting down toward the ultimate science ride, a weightless flight aboard a modified NASA jet to see just how certain fires burn in zero gravity.

Scientists are confused about topic of Global Warming

Scientists are confused about the predictions of the apocalypse while some experts promise to hide the carbon dioxide into the ground, the other frightening collapse of the power system topic of global warming and the related phenomenon of threats continues to occupy the minds of scientists, with no time to receive one prediction, 

6 amazing facts about black holes

This is what happens when the universe divides by zero. They arise when the reality shows a critical error: too much material in one place the power of its own gravity and spoils the substance, and the place in which it is located. Usually gravity in our universe is playing the role of a caring older brother who always preterit for younger scattered toys. But in the case of black holes, gravity becomes downright Al Capone, which first convened a meeting the entire fundamental laws of life, and then arranges a real meat grinder with their participation. 

End of the Universe can happen at any time

Last year, the Large Hadron Collider has been defined mass "God particle" - the Higgs boson. Its importance was such that can turn all preconceived ideas about the "strength" of our world - the end of the universe can come at any moment, and the source of the death of the universe may appear at any point. Traditionally, the end of the universe, scientists "suggested" three basic scenarios . And they were all tied to the properties of dark energy - a hypothetical phenomenon through which modern physics explains why our universe is expanding with acceleration.
