NASA has discovered frozen water and earth-like blue skies on Pluto in another historic development in the search for extraterrestrial life. Just 10 days after confirming that liquid water has been found on Mars, the US space agency revealed the amazing dwarf-planet has both ice and a 'gorgeous' blue sky. A Nasa spokesman said: "New Horizons has detected numerous small, exposed regions of water ice on Pluto. "The discovery was made from data collected by the Ralph spectral composition mapper on New Horizons." There has been repeated speculation Pluto may have a liquid sea under its surface, and confirmation of...

Here’s what happens if astronomers make contact with a civilization on another planet.The false alarm happened in 1997. The Green Bank Radio Observatory in Green Bank, West Virginia, was picking up some unusual signals—and Seth Shostak, then the head of the Center for Search for Extraterrestrial Intelligence (SETI) Research in Mountain View, Caifornia, was convinced that they had come from intelligent life somewhere in the universe. “It looked like it might be the real deal,” Shostak recalled. Within a few hours, he had a call from The New York Times. But within a day, it became clear that the source...

This past week, four tasters at the Ardbeg Distillery in Islay, Scotland drank samples of whiskey that had aged for nearly three years aboard the International Space Station. They compared the samples to whiskey that had matured in a similar way here on Earth. The team said the space samples were completely unlike anything they had ever tasted before; something about the space environment had a distinct effect on the alcoholic beverage. "It was the most unusual tasting we’d ever done," Dr. Bill Lumsden, head of distilling and whiskey creation at the Glenmorangie Company, told The Verge. "I was amazed...

SpaceX's new Crew Dragon capsule may be reserved for astronauts traveling to and from the International Space Station — but now you can take a virtual tour of the vehicle's insides. The company just released interior photos of the spacecraft, as well as a video showing closeups of its control panels and crew seats. The images offer our first glimpse at what the finished Crew Dragon will look like. The photos show an interior that is sleek and smooth, with mostly black and white hardware. It gives off the vibe of a luxury sports car (which makes sense, given CEO...

In aviation circles, the talk of the future involves phrases like "space planes" and "hypersonic atmospheric flight vehicles." A group presently in the spotlight is from Germany; they are carrying a roadmap for low-cost space access which involves calling upon the air passenger market for fast-travel flights. Welcome to the world of SpaceLiner, which, when fully developed, could have dramatic impact in global aerospace. The DLR Institute of Space Systems said this suborbital, hypersonic, winged passenger transport idea is under investigation at DLR-SART. (DLR is a German aerospace research agency and it evaluates complex systems of space flight. SART is...

20 km Space Tower ====================================================================================================================== Exploring space while seated on Earth, gazing up on screens in museum theaters or at home via VR headsets. is exciting but the top imagination-grabber is the very idea of finding a way to access space. This is the present-day realm of creative thinking over space elevators, in the use of a giant tower to carry us to space. Scientists working on space elevators are thinking about materials and designs that can be used to access space as an alternative to rocket technology. A sign of the times is the upcoming Space Elevator Conference...

(Aug. 13) successful test firing of an RS-25 main stage engine for NASA’s Space Launch System (SLS) monster rocket currently under development, the program passed a key milestone advancing the agency on the path to propel astronauts back to deep space at the turn of the decade. The 535 second long test firing of the RS-25 development engine was conducted on the A-1 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi – and ran for the planned full duration of nearly 9 minutes, matching the time they will fire during an actual SLS launch. All indications...

EGSY8p7 is the most distant confirmed galaxy whose spectrum obtained with the W. M. Keck Observatory places it at a redshift of 8.68 at a time when the Universe was less than 600 million years old. The illustration shows the remarkable progress made in recent years in probing early cosmic history. Such studies are important in understanding how the Universe evolved from an early dark period to one when galaxies began to shine. Hydrogen emission from EGSY8p7 may indicate it is the first known example of an early generation of young galaxies emitting unusually strong radiation. Credit: Adi Zitrin, California...

Earth just got a new next-door neighbor.Astronomers have found the closest rocky planet outside our solar system using the Spitzer Space telescope. The planet, known as HD 219134b, orbits a star just 21 light years away, and NASA is calling a "potential gold mine of science data." The planet is probably a bad place for life as we know it: it’s 1.6 times the size of Earth and more than four times the mass. Plus its three-day orbit is too close to its host star for liquid water to form, even though the star is cooler and smaller than our...

Two German researchers claim they have produced measurable amounts of thrust using a copy of NASA’s controversial EMDrive. It’s a result that has many people talking, but don’t plan your trip to the to the Alpha Centauri system just yet—the experts we spoke with are all highly skeptical of the study and its findings. As reported in Hacked, the details of the new study are being presented this week by Martin Tajmar, a professor and chair for Space Systems at the Dresden University of Technology, and co-author G. Fiedler, at the American Institute for Aeronautics and Astronautics’ Propulsion and Energy...

[Now this would be really cool! Hope it pans out!] 'Impossible' rocket drive works and could get to Moon in four hoursThe British designed EM Drive actually works and would dramatically speed up space travel, scientists have confirmedBy Sarah Knapton, Science Editor 6:04PM BST 28 Jul 2015 Interplanetary travel could be a step closer after scientists confirmed that an electromagnetic propulsion drive, which is fast enough to get to the Moon in four hours, actually works. The EM Drive was developed by the British inventor Roger Shawyer nearly 15 years ago but was ridiculed at the time as being scientifically...

=============================================================================================== A team of researchers at Colorado based Escape Dynamics is reporting that initial tests indicate that it might really be possible to launch space-planes into space using microwaves sent from the ground, to allow for a single stage spacecraft. If the idea pans out, the cost savings for sending satellites (or perhaps humans) into orbit could be considerable. Today's rockets are all based on the same idea, a multi-stage rocket is used, each part filled with propellant that pushes the rocket into space as the propellant is burned. It is a really expensive way to go because the propellant...

An asteroid worth a potential £3.5 trillion ($5.4 trillion) is due to pass by Earth on Sunday, and you can watch it live from 11pm UK time (6.30pm ET). Asteroid 2011 UW-158's fly-by will be streamed live on the internet from an observatory in the Canary Islands. The space rock has attracted the attention of asteroid mining company Planetary Resources, because it is thought to have a 100 million ton core of platinum that the company might one day want to exploit. Asteroid 2011 UW-158 will pass within 1.5 million miles (2.4 million km) from Earth on Sunday - 30...

Artist's impression showing a newly discovered Jupiter twin gas giant orbiting the solar twin star, HIP 11915. The planet is of a very similar mass to Jupiter and orbits at the same distance from its star as Jupiter does from the Sun. This, together with HIP 11915's Sun-like composition, hints at the possibility of the system of planets orbiting HIP 11915 bearing a resemblance to our own Solar System, with smaller rocky planets orbiting closer to the host star.

European Space Agency Cluster II satellites observe equatorial noise waves inside the Earth's magnetosphere. Credit: ESA/Yuri Shprits ********************************************************************************************************************************************************** Since the early 1970s, orbiting satellites have picked up on noise-like plasma waves very close to the Earth's magnetic field equator. This "equatorial noise," as it was then named, seemed to be an unruly mess of electric and magnetic fields oscillating at different frequencies in the form of plasma waves. Now a team from MIT, the University of California at Los Angeles, the University of Sheffield, and elsewhere has detected a remarkably orderly pattern amid the noise. In a region of space...
