Earth-Like Planet Found Orbiting the Nearest Star - Astronomers just discovered the closest possible Earth-like planet outside our solar system. It orbits our closest neighboring star, Proxima Centauri. The planet is warm enough for liquid water, is almost certainly rocky and terrestrial, and could even have an atmosphere. At just 4.2 light years away, scientists are even wondering if this may be the closest home for life outside our solar system From Surfer
The Atmosphere of Venus Is More Terrifying Than We Imagined - Scientists have long suspected that all planets with an atmosphere also have an electric field, generated by a layer of charged particles in the upper atmosphere called the ionosphere.

$100-Million Plan Will Send Probes to the Nearest Star - Scientific American - â€śBreakthrough Starshot,â€ť the program Milner is backing, intends to squeeze all the key components of a robotic probeâ€”cameras, sensors, maneuvering thrusters and communications equipmentâ€”into tiny gram-scale â€śnanocraft.â€ť These would be small enough to boost to enormous speeds using other technology the program plans to help develop, including a ground-based kilometer-scale laser array capable of beaming 100-gigawatt laser pulses through the atmosphere for a few minutes at a time, and atoms-thin, meter-wide â€ślight sailsâ€ť to ride those beams to other stars. Each pinging photon of light would impart a slight momentum to the sail and its cargo; in the microgravity vacuum of space, the torrent of photons unleashed by a gigawatt-class laser would rapidly push a nanocraft to relativistic speeds.

'God particle' could destroy universe, says Stephen Hawking - Either all of space-time exists on this razor's edge between a stable and unstable universe, or the calculation is wrong, Lykken said.
If the calculation is wrong, it must come from a fundamental part of physics that scientists have not discovered yet. Lykken said one possibility is the existence of invisible dark matter that physicists believe makes up about 27 percent of the universe. Discovering how dark matter interacts with the rest of the universe could reveal properties and rules physicists don't know about yet.
The other is the idea of "supersymmetry." In the Standard Model, every particle has a partner, or its own anti-particle. But supersymmetry is a theory that suggests every particle also has a supersymmetric partner particle. The existence of these other particles would help stabilize the universe, Lykken said.

Famous Star Explosion Lit by Ultrafast Mach 1,000 Shock Wave - Astronomers studying the remnants of a well-known stellar explosion discovered a blisteringly fast shock wave that is rushing inward at 1,000 times the speed of sound, lighting up what remains of the powerful cosmic explosion.
As this expelled material impacted the surrounding interstellar gas, it created a shock wave that functions similar to a cosmic sonic boom. This shock wave is still expanding today, swelling outwards at 300 times the speed of sound, according to the researchers. These dynamics also triggered a reverse shock wave that is traveling inward at Mach 1000.

Humanity escapes the solar system: Voyager 1 signals that it has reached the edge of interstellar space | Mail Online - With absolutely no attempt at hyperbole at all, it is fair to say that this is one of - if not the - biggest achievement of the human race.For, as we speak, an object conceived in the human mind, and built by our tools, and launched from our planet, is sailing out of the further depths of our solar system - and will be the first object made by man to sail out into interstellar space.The Voyager 1, built by Nasa and launched in 1977 has spent the last 35 years steadily increasing its distance from Earth, and is now now 17,970,000,000km - or 11,100,000,000miles - away, travelling at 10km a second.Indications over the last week implies that Voyager 1 is now leaving the heliosphere - the last vestige of this solar system.

The Moon's Peculiar Dust Gets More Peculiar Still - That dust, the Apollo crewmen found when they went out to play in it, did some strange things: it rose above the surface when disturbed and hung there far longer than could be explained by the moon's weak gravity; it crept deep into the weave and cracks of virtually anything it touched and clung there as if adhesively attached. What's more, it was filled with exquisitely fine green and orange glass beads -- the products of the superheated melting and cooling that followed impacts. From cw

Milky Way Headed for Huge Galactic Crash in 4 Billion Years - Our Milky Way is bound for a head-on collision with the similar-sized Andromeda galaxy, researchers announced today (May 31). Over time, the huge galactic smashup will create an entirely new hybrid galaxy, one likely bearing an elliptical shape rather than the Milky Way's trademark spiral-armed disk. From cw
Preserving our Dark Skies - One of my favorite quotations comes from Neil Degrasse Tyson when he is describing his first view of a truly dark sky. He notes that his first thought is how much it reminds him of the Hayden Planetarium, not the other way around! Many of us never forget that first experience of seeing a truly dark sky; seeing so many stars above that the world seems wrapped in a blanket of light. Without the lights below, a passing cloud looks like a giant black hole eating a portion of the sky as it passes overhead. Strange as it may seem, if you have experienced this, you are lucky. Many kids and even many adults never experience that wonder, and one can only imagine what the consequences of this are. From cw
Period of the Sun's Orbit around the Galaxy (Cosmic Year) - The sun is one of hundreds of billion of stars in our galaxy, the Milky Way. The galaxy is composed of gaseous interstellar medium, neutral or ionized, sometimes concentrated into dense gas clouds made up of atoms molecules, and dust. All of the matter -- gas, dust, and stars -- rotate around a central axis perpendicular to the galactic plane. The centrifugal force caused by the rotation balances out the gravitational force, which draw all the matter toward the center. From cw

Top 10 Really Cool Infrared Images from Spitzer - The Spitzer Space Telescope’s Infrared Array Camera (IRAC) is a cool camera, no matter what temperature in which it operates! For 1,000 days now, the camera has been continuously taking images of the Universe – from its most distant regions to our local solar neighborhood. The IRAC is now operating in a “warm” version of its mission, as after more than five-and-a-half years of probing the cool cosmos, in 2009 it ran out of liquid helium coolant that kept its infrared instruments chilled.

Destroying an Incoming Killer Asteroid With a Nuclear Blast | Popular Science - One way or another, it's on everyone's minds, living somewhere in the back of our collective consciousness. Hollywood knows it, and continues to plumb it for box office numbers. The fossil record shouts warnings across millennia about it. Even the dinosaurs developed a particular, albeit brief, loathing for it.
The killer asteroid - the one that we might never even see coming - could end life on this planet and there would be nothing humans could do about it. It creates a kind of helplessness that's difficult to even think about. But simulations show how unleashing Earth's destructive arsenal into deep space could save the planet. From X Isle

Kepler Mission extended to 2016 - With NASA's tight budget, there were concerns that some of the agency's most successful astrophysics missions might not be able to continue. Anxieties were rampant about one mission in particular, the very fruitful exoplanet-hunting Kepler mission, as several years of observations are required in order for Kepler to confirm a repeated orbit as a planet transits its star. But today, after a long awaited Senior Review of nine astrophysics missions, surprisingly all have received funding to continue at least through 2014, with several mission extensions, including Kepler.

Fresh Tiger Stripes on Saturns Enceladus - Enceladus has always been thought of as one of the more remarkable members of Saturn's marble bag of satellites. For one thing, it's dazzlingly bright. The percentage of sunlight that a body in the solar system reflects back is known as its albedo, and it's determined mostly by the color of the body's ground cover. For all the silvery brilliance of a full moon on a cloudless night, the albedo of our own drab satellite is a muddy 12%, owing mostly to the gray dust that covers it. The albedo of Enceladus, on the other hand, approaches a mirror-like 100%. Such a high percentage likely means the surface is covered with ice crystals -- and, what's more, that those crystals get regularly replenished.. From X Isle
Mercury Has a Liquid Core - NASA’s Messenger spacecraft entered orbit around Mercury one year ago this week, and the spacecraft has been hard at work. It has captured nearly 100,000 images, mapped Mercury’s gravity field, and taken sensitive altimetry measurements that are shedding light on the planet’s surface features like never before. This week, scientists on the Messenger mission published another round of new findings about the innermost planet, which turns out to be an altogether weirder world than we'd thought. From Guest_2012
NASA - Mapping the Infrared Universe - The Entire WISE Sky - Nasa released an image of the entire sky as observed by the Wide-field Infrared Survey Explorer. The sky can be thought of as a sphere that surrounds us in three dimensions. To make a map of the sky, astronomers project it into two dimensions. The projection used in this image of the sky, called Aitoff, takes the 3-D sky sphere and slices open one hemisphere, and then flattens the whole thing out into an oval shape.
In the mosaic, the Milky Way Galaxy runs horizontally across this map. The Milky Way is shaped like a disk and our solar system is located in that disk about two-thirds of the way out from the center. So we see the Milky Way as a band running through the sky. From X Isle

Did life on Earth actually come from the Red Planet? - Given the same raw materials, Mars would have been a better host for life to arise than Earth, which some scientists believe was too flooded for the chemistry of life to gain a toehold.
Without at least occasional dry land, the chemistry needed to get life started doesn’t work very well because the molecules to support genetics, such as RNA, are chemically unstable in many ways, particularly in water. From Popper
