Scientists have split light into a ring of multiple beams to form a pipe like an optical fibre. This allows them to transmit light through air without losing intensity. It could one day be used for long distance communication in space: http://ab.co/1xff8r2 via ABC Science.

This is the Best Footage Yet of an Exoplanet Orbiting its Star
Posted by Sean Brazell in category: space
And…it’s literally six seconds of pixelated blob. But before you laugh, know this: Capturing that planetary transit you just witnessed was no easy task.
You’re looking at Beta Pictoris b, a gas giant ten to twelve times the mass of Jupiter that orbits a star over 60 light years away. That’s 3.527 × 1014 miles from us, and we’re actually able to see it! If you’re still not impressed, try this on for size: Beta Pictoris b is roughly a million times dimmer than its parent star.

The dimensional aspect of existence is associated with the dimensions of space and time.
Posted by Shailesh Prasad in categories: cosmology, evolution, information science, materials, neuroscience, particle physics, quantum physics, singularity, space
The dimensionless aspect, since it has no dimensions, is outside of space and time. This is the key aspect to existence: an aspect outside of space and time perpetually interacting dialectically with an aspect inside space and time. All of the weird and wonderful phenomena of the universe are the products of this ultimate dichotomy.
Does this sound crazy? Then consider the evidence provided by black holes.
The R = 0 Universe.

Something Bizarre Is Happening On the Surface of Rosetta’s Comet
Posted by Sean Brazell in category: space
They may not look like it, but each of these photos from Rosetta is of the same site on Comet 67P/ Churyumov-Gerasimenko, within just six short weeks. Something big is happening up there—but what is it?
This particular comet site has been steadily monitored by the ESA since August of 2014, and nothing has been happening. Literally. Viewed in detail of up to 1/10 of a meter, the site had stayed exactly the same. Until late May, when suddenly everything started changing again and again and again.
Some land features disappeared, others were added. Some were temporary, some stayed. What’s happening there and why? Scientists still aren’t sure, but they’ve come up with a few theories:

Asteroid-Mining Plan Would Bake Water Out of Bagged-Up Space Rocks
Posted by Klaus Baldauf in categories: business, space
PASADENA, Calif. — A new way to harvest asteroid resources is being eyed as a possible game changer for space exploration.
The patent-pending innovation, called “optical mining,” could allow huge amounts of asteroid water to be tapped, advocates say. This water, in turn, could provide relatively cheap and accessible propellant for voyaging spacecraft, lowering the cost of spaceflight significantly.
Development of the optical-mining idea has been funded by a NASA Innovative Advanced Concepts (NIAC) fellowship and grant, along with a small business contract. The concept — which is also known as the Asteroid Provided In-Situ Supplies plan, or Apis — was detailed here during a special NIAC session held on Sept. 2 during the American Institute of Aeronautics and Astronautics’ (AIAA) Space 2015 meeting.

The world’s first all-electric propulsion satellite is now operational
Posted by Shailesh Prasad in categories: electronics, internet, space
Boeing has announced that the ABS–3A, the world’s first all-electric propulsion satellite, has commenced its tour of duty.
The communications satellite is being operated by ABS, a Bermuda-based satellite network that provides TV, Internet, and cellular services across the world. Unlike conventional satellites, which have mostly used propellant systems that burn chemicals of one kind or another to get about the place, the ABS–3A makes use of a xenon-ion propulsion system to achieve thrust.
Specifically, the all-electric propulsion system uses electron bombardment to create xenon ions, which are then expelled by the spacecraft, producing thrust in the opposite direction.

NASA confirms there’s a global subsurface ocean on Enceladus
Posted by Sean Brazell in category: space
We’ve known there is water on Enceladus for a while now, but NASA has just confirmed a more recent theory about the icy moon of Saturn: it has a subsurface ocean that spans the entire globe. The news comes just a handful of months after the agency discovered evidence of hydrothermal vents, which are believed to be integral to the formation of life here on Earth.
The confirmation was made using research from Cassini — a spacecraft that arrived at Saturn in 2004 and has spent the last decade studying the planet and its many moons. (It was launched in 1997.) The researchers used Cassini to measure the wobble in Enceladus’ orbit of Saturn, something that “can only be accounted for if its outer ice shell is not frozen solid to its interior.”
