‘Billions’ of habitable planets discovered in the Milky Way Galaxy

March 28, 2012

“Scientists say that where there is water, there also could be life although they add that being in the habitable zone is no guarantee that life has evolved on a planet.”

Russia to send cosmonauts to the Moon for the first time

March 14, 2012

“A spacecraft will “conduct a demonstrative manned circumlunar test flight with the subsequent landing of cosmonauts on [the Moon’s] surface and their return to Earth” by 2030, according to a leaked strategy document from Russia’s space agency, Roskosmos.”

NASA Study: Space flight may damage human eyesight

March 14, 2012

“They found that those who spent more than a month in space were more likely to suffer from intracranial hypertension — a potentially serious condition that occurs when pressure builds within the skull.”

Largest solar flare in 5 years to hit Earth Thursday, expected to temporarily disrupt GPS, power grids, and airplane flights

March 7, 2012

“The sun erupted Tuesday evening, and the effects should start smacking Earth around 7 a.m. EST Thursday, according to forecasters at the federal government’s Space Weather Prediction Center. They say the flare is growing as it speeds outward from the sun.”

Earth’s Polar Ice Caps melting at a slower rate than previously estimated, however the amount of ice melted between 2003 to 2010 would still to be able cover the entire United States with 18 inches of water

February 9, 2012

“While vast quantities of ice melting into the ocean is not exactly good news, Wahr says, according to his team’s estimates, about 30 percent less ice is melting than previously thought.”

NASA Probe captures the first video of the dark side of the Moon

February 2, 2012

“The new video was captured by one of NASA’s twin Grail probes using a novel camera called MoonKAM, which will eventually be used by students on Earth to snap photos of the lunar surface as part of an educational project. The two spacecraft have been circling the moon since they arrived in orbit over the New Year.”

Research: Concerns grow over magma pools in the U.S. that could trigger volcanic erputions

February 2, 2012

“Scientists have known for decades that hidden under those impressive vistas at sites such as Death Valley and Yellowstone National Park are magma pools that under the right conditions can trigger explosive eruptions. Now, new research is changing scientists’ understanding of the timing of those eruptions, and prompting them to call for greater monitoring of sites to help save lives when the next big volcano explodes.”

Solar eruption sparks the strongest radiation storm in 7 years

January 23, 2012

“Early this morning (0359 GMT Jan. 23, which corresponds to late Sunday, Jan. 22 at 10:59 p.m. EST), NASA’s Solar Dynamics Observatory caught an extreme ultraviolet flash from a huge eruption on the sun , according to the skywatching website Spaceweather.com.”

American Association for the Advancement of Science Article: Mitigating Climate Change to improve human health and food security without major sacrifices

January 20, 2012

“After looking at hundreds of ways to control these pollutants, the researchers determined the 14 most effective measures for reducing climate change, like encouraging a switch to cleaner diesel engines and cookstoves, building more efficient kilns and coke ovens, capturing methane at landfills and oil wells, and reducing methane emissions from rice paddies by draining them more often.”

NASA finds a planet outside of our solar system that likely has water and its star is similar to our sun

December 5, 2011

“Scientists say the temperature on the surface of the planet is about a comfy 72 degrees. Its star could almost be a twin of our sun. It likely has water and land. It was found in the middle of the habitable zone, making it the best potential target for life yet.”

Russia has ‘no idea’ where its failed Mars probe will crash

November 24, 2011

“Russian space agency Roscosmos all but gave up on regaining contact with its lost Mars probe, and it has no idea where exactly it will crash back down to Earth when it finally falls out of orbit.

The unmanned Phobos-Grunt spacecraft blasted off toward the Red Planet on Nov. 9, where it was hoped to bring back rock and soil samples from the moon Phobos.”

Nobel Prize Winning Physicist Norman F. Ramsey dead at age 96

November 10, 2011

“Norman F. Ramsey, 96, a Nobel Prize-winning physicist whose work with atoms, nuclei and electromagnetic radiation spurred great progress in such areas as the measurement of time and the development of medical imaging devices, died Nov. 4 at his home in Wayland, Mass.

His wife, Ellie, confirmed the death but did not disclose the cause.

Few scientists of Dr. Ramsey’s era made so many contributions that proved so fruitful in so many fields. A longtime Harvard professor, he was honored by the Nobel committee in 1989 for work leading to the ultra precise cesium atomic clock and the hydrogen maser. Such precision timekeeping devices help govern Global Positioning System operations.

In addition, his studies of the magnetic properties of the atomic nucleus and of how these properties express themselves in the phenomenon of nuclear magnetic resonance helped in the creation of one of medicine’s most powerful diagnostic techniques, magnetic resonance imaging.”

White House: No contact with aliens yet, but we’re looking

November 8, 2011

“The Obama administration’s position on the existence of aliens, and whether the people of Earth have had contact with them, can be summed up this way: “Searching for ET, but no evidence yet.”

That’s the title of the official White House response to an online petition signed by 12,078 people that asks the government to acknowledge an “extraterrestrial presence engaging the human race.”

“Hundreds of military and government agency witnesses have come forward with testimony confirming this extraterrestrial presence,” the writers of the petition contend. “Opinion polls now indicate more than 50% of the American people believe there is an extraterrestrial presence and more than 80% believe the government is not telling the truth about this phenomenon. The people have a right to know. The people can handle the truth.”

Names of three elements approved for the Periodic Table

November 8, 2011

“Elements 110, 111 and 112 have been named darmstadtium (Ds), roentgenium (Rg) and copernicium (Cn).

The elements are so large and unstable they can only be made in the lab and quickly break down into other elements.

They are known as Super-heavy elements.”

Hubble Telescope captures image of a disk, made of gas and dust, surrounding a black hole

November 8, 2011

“Using the Hubble space telescope, astronomers have captured a direct image of the disk surrounding a black hole.

The disk is made of gas and dust, slowly being consumed as it spirals down into the black hole’s center. As it falls in, the material spews out a tremendous amount of energy, forming what is known as a quasi-stellar radio source, or quasar.

Among the brightest objects in the sky, quasars are short-lived phenomena that only existed during the earliest eras of the universe. They are known to be huge — most are around 60 billion miles across — yet they lie billions of light years from Earth, making them nothing but insignificant pinpricks in even the most powerful telescopes.

Hubble was able to image the distant disk, which is approximately 18.5 billion light-years away, because a huge galaxy happens to sit between Earth and the quasar. The mass of the enormous galaxy bent light from the quasar and directed it toward our telescopes, acting like a gigantic gravitational lens.”
