Gravitational waves from black holes detected - BBC News - 1 views

  •  
    From the section Science & Environment Scientists are claiming a stunning discovery in their quest to fully understand gravity. They have observed the warping of space-time generated by the collision of two black holes more than a billion light-years from Earth.

Caltech Researchers Find Evidence of a Real Ninth Planet | Caltech - 0 views

  •  
    Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles).

In a new round of testing, NASA confirms yet again that the 'impossible' EMdrive thrust... - 4 views

  •  
    Engineer Roger Shawyer's controversial EM Drive thruster jets back into relevancy this week, as a team of researchers at NASA's Eagleworks Laboratories recently completed yet another round of testing on the seemingly impossible tech.

    I like this just because it will end up on Thijs' desk :D

Watch Uranium Emit Radiation - 2 views

  •  
    You've heard of the catastrophic effects of radiation on environments, animals and humans. A seemingly silent and invisible destroyer, radiation can make whole cities inhabitable for hundreds of years. But have you ever wondered what radiation actually looks like? There may be one image that jumps to mind.

    We saw the same detector setup in the room opposite to ours during the Open Day! Using uranium is just cooler. :)

Earth's extremes point the way to extraterrestrial life - 1 views

  •  
    Seems a little speculative but pretty interesting thoughts. In regards to terraforming Mars this might be of interest:
    "During the daytime, plant-like microorganisms on a Martian-like surface could photosynthesize hydrogen peroxide. At night, when the atmosphere is relatively humid, they could use their stored hydrogen peroxide to scavenge water from the atmosphere, similar to how microbial communities in the Atacama use the moisture that salt brine extracts from the air to stay alive."

ISS astronauts bite into space-grown lettuce - 0 views

    Next great step for humankind.

Why is life left-handed? The answer is in the stars - 2 views

  •  
    While most humans are right-handed, our proteins are made up of lefty molecules. In the same way your left and right hands mirror one another, molecules can assemble in two reflected structures. Life prefers the left-handed version, which is puzzling since both mirrored types form equally in the laboratory.

Student Confirms That There Are Enormous Tubes Of Plasma Floating Above The Earth - 1 views

  •  
    A 60-year-old theory about the structure of the magnetic fields that surround Earth has been confirmed directly for the first time. The lead author of the paper is an undergraduate student who invented a way to view the Earth's magnetosphere in three dimensions.

What happens to your brain on the way to Mars - 1 views

  •  
    This study from NASA shows that cosmic rays have a deleterious effect on the brain, more than expected, resulting in in symptoms similar to dementia (memory loss, decline in problem solving skills, general cognitive functions).

    A reason more to investigate into hibernation?

    NASA Releases Tool Enabling Citizen Scientists to Examine Asteroid Vesta

    Vesta Trek is a free, web-based application that provides detailed visualizations of Vesta, one of the largest asteroids in our solar system.

    NASA's Dawn spacecraft studied Vesta from July 2011 to September 2012. Data gathered from multiple instruments aboard Dawn have been compiled into Vesta Trek's user-friendly set of tools, enabling citizen scientists and students to study the asteroid's features. The application includes:

    -- Interactive maps with the ability to overlay a growing range of data sets including topography, mineralogy, abundance of elements and geology, as well as analysis tools for measuring the diameters, heights and depths of surface features and more.

    -- 3-D printer-exportable topography so users can print physical models of Vesta's surface.

    -- Standard keyboard gaming controls to manoever a first-person visualization of "flying" across the surface of the asteroid.

    "There's nothing like seeing something with your own eyes, but these types of detailed data-visualizations are the next best thing," said Kristen Erickson, Director, Science Engagement and Partnerships at NASA Headquarters in Washington DC.

Medical Xpress: Newly discovered hormone mimics the effects of exercise - 0 views

  •  
    "Hormones are molecules that act as the body's signals, triggering various physiological responses. The newly discovered hormone, dubbed "MOTS-c," primarily targets muscle tissue, where it restores insulin sensitivity, counteracting diet-induced and age-dependent insulin resistance."

    Good news for long distance space travelers?

Alien star invaded the Solar System - 2 views

  •  
    An alien star passed through our Solar System just 70,000 years ago, astronomers have discovered. No other star is known to have approached this close to us. An international team of researchers says it came five times closer than our current nearest neighbour - Proxima Centauri.

    Passing straight through the Oort Cloud region. This must have left some sort of mark maybe? A binary system of a red and brown dwarf (8% and 6% solar masses) so maybe not a too significant impact on trajectories in the Oort cloud?
  •  
    I read this earlier and thought it might be another one of those alien conspiracy stuff. Freaky stuff.
  •  
    what about taking a ride on one of these? - especially if they come with some companion planets? when is the next shuttle coming?

    Mining the moon - now we know that the Moon's poles hold millions of tonnes of water ice, firms in the US as well as the Indian and Chinese space agencies are planning to mine this resource and sell it to space missions as fuel.

Lost Beagle 2 spacecraft found intact on Martian surface - 0 views

  •  
    The UK-led Beagle 2 Mars lander, thought lost on the red planet since 2003, has been found partially deployed on the Martian surface. New images show that it successfully touched down on the planet's surface in 2003 but failed to deploy all four of its solar panels, thereby allowing no communication with scientists on Earth.

New apps allow smartphone users to join the hunt for ultrahigh-energy cosmic rays - 0 views

  •  
    Two apps - the Distributed Electronic Cosmic-ray Observatory (DECO) and Cosmic Rays Found in Smartphones (CRAYFIS) - transform smartphones into miniature cosmic-ray detectors. They use the CMOS chips inside phones' onboard cameras to detect the secondary particles produced when cosmic rays - energetic, charged subatomic particles arriving from beyond the solar system - collide with air molecules in the Earth's atmosphere

Cloud cities for Venus exploration - 3 views

  •  
    Our friends from NASA have come out with a plan to the human exploration of Venus in the time that everyone is speaking about Mars.
  •  
    Love the concept acronym, which pretty much says it all... Not sure which astronaut would fancy floating around in an atmosphere where clouds are made of sulphuric acid.
    Besides I don't see the point of a manned mission if one can't reach the surface.. tele-operation would be easy and so much cheaper.
