What you’re looking at are human beings assembling humanity’s most advanced space telescope to date. At this very moment, the James Webb Space Telescope (@NASAWebbTelescp) is being assembled. To keep up to date on its progress, you can visit NASA’s dedicated web page on the scope.
Here’s what you should know.
The James Webb Space Telescope (aka JWST or Webb) will be a large infrared telescope with a 6.5-meter primary mirror, launched on an Ariane 5 rocket from French Guiana in October 2018, and will be the premier observatory of the next decade, serving thousands of astronomers worldwide. JWST will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System. Formerly known as the “Next Generation Space Telescope” (NGST); it was renamed in Sept. 2002 after a former NASA administrator, James Webb.
JWST is an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The NASA Goddard Space Flight Center is managing the development effort, with the main industrial partner being Northrop Grumman; the Space Telescope Science Institute will operate JWST after launch. Over 1000 people in more than 17 countries are developing the James Webb Space Telescope. Shown above are team members in front of the JWST full-scale model at the Goddard Space Flight Center in Greenbelt, Maryland.
Several innovative technologies have been developed for JWST. These include a primary mirror made of 18 separate segments that unfold and adjust to shape after launch. The mirrors are made of ultra-lightweight beryllium. JWST’s biggest feature is a tennis court sized five-layer sunshield that attenuates heat from the Sun more than a million times. The telescope’s four instruments - cameras and spectrometers - have detectors that are able to record extremely faint signals. One instrument (NIRSpec) has programmable microshutters, which enable observation up to 100 objects simultaneously. JWST also has a cryocooler for cooling the mid-infrared detectors of another instrument (MIRI) to a very cold 7 degrees Kelvin so they can work.
Of the myriad of capabilities Webb will have over the now 25 year old Hubble Space Telescope (HST), the most fascinating aspects of the JWST will be all we expect to learn, along with discoveries it will enable of which we couldn’t possibly anticipate.

Although there’s so much more to say about the JWST, I recommend visiting http://jwst.nasa.gov/ to browse the trove of resources available. And because @nasa prides itself on being a transparent and inclusive organization, everyone can view the past and present progress being made through the live web cams which provide fresh views every 60 seconds!

Share this with everyone! We are all crew members aboard this terrestrial spaceship, and although we all share the same window to the universe, not everyone has the influences around them to assist in helping refine their questions, and ultimately, change their perspective regarding their ‘place in space’. Every person you reach and inform about the incredible science that’s being done around our busy world, the immeasurable impact you could have on their life and the subsequent lives they influence. Engage and educate!

Goleta CA (SPX) Nov 27, 2015 A team of astronomers have used the LCOGT network to detect light scattered by tiny particles (called Rayleigh scattering), through the atmosphere of a Neptune-size transiting exoplanet. This suggests a blue sky on this world which is only 100 light years away from us. Transits occur when an exoplanet passes in front of its parent star, reducing the amount of light we receive from the star Full article

Almost a month ago, the spaceflight company Blue Origin sent a rocket up to the edge of space and then guided it gracefully back down to earth, intact. It was a historic first.
But Blue Origin’s major competitor, SpaceX, was quick to point out that the rocket wasn’t going fast enough (or sideways enough) to place a satellite into orbit - just 4,600 kph (~2,860 mph). It went straight up, and then straight down.
Now, SpaceX has managed to put 11 satellites in orbit with a “reusable” rocket. Their rocket didn’t just go up and down - it reached a horizontal velocity of 6,000 kph (3,600 mph) before returning to earth. If SpaceX is able to refurbish the rocket and use it in another launch, they’ll have figured out a way to dramatically reduce the cost of spaceflight.
Here’s the full webcast. And here’s the full story.

Rosemary Johnson was a promising violinist and member of the Welsh National Opera Orchestra when she was involved in a devastating car crash 27 years ago. The accident left her in a coma for seven months, and the resulting brain damage has robbed her of most of her ability to talk and move.
But thanks to new software that reads people’s brain waves, Johnson has been able to compose music for the first time since 1988, and has had the chance to have it played to her in real time by a professional string quartet.
“It was really very moving,” Eduardo Miranda from the Interdisciplinary Centre for Computer Music Research at Plymouth University in the UK, told The Telegraph.
Humans might not be the only creatures that care about the welfare of other animals. Scientists are beginning to recognize a pattern in humpback whale behavior around the world, a seemingly intentional effort to rescue animals that are being hunted by killer whales.
Marine ecologist Robert Pitman observed a particularly dramatic example of this behavior back in 2009, while observing a pod of killer whales hunting a Weddell seal trapped on an ice floe off Antarctica. The orcas were able to successfully knock the seal off the ice, and just as they were closing in for the kill, a magnificent humpback whale suddenly rose up out of the water beneath the seal.
This was no mere accident. In order to better protect the seal, the whale placed it safely on its upturned belly to keep it out of the water. As the seal slipped down the whale’s side, the humpback appeared to use its flippers to carefully help the seal back aboard. Finally, when the coast was clear, the seal was able to safely swim off to another, more secure ice floe.

Can we just take a moment to appreciate how incredible our Solar System is? Sure, pretty much everywhere other than our own planet is a deathtrap, with acid rain pouring down on Venus and storms three times the size of Earth swirling around Jupiter, but you don’t have to look too hard to find the unique beauty in our neighbouring planets and moons.
And with unique beauty comes… tourism! From the diamond-inspired cloud observatory of Venus to Jupiter’s aurorae-backed balloon ride, the design team from NASA’s Jet Propulsion Laboratory (JPL) have taken us back to the future with this new batch of retro space tourism posters.
The “Visions of the Future” series features seven original posters released this week, plus seven “Exoplanet Travel Bureau” posters that were published around this time last year. And these haven’t just been dreamt up by anyone - the designers behind the posters have been consulting with JPL scientists and engineers to come up with tourism scenarios that are as realistic as they are fantastical.

Could two same-sex partners ever be biologically related to one baby? Maybe. With a relatively new process called in vitro gametogenesis, or IVG, scientists could combine genetic material from both parents. While we may have to wait a bit for it — here’s how it works.
