A strange case - a Neptune-sized exoplanet is bleeding hydrogen. Could something similar have happened to Earth? http://hubblesite.org/newscenter/archive/releases/2015/17/full/

One of #JWST's primary goals is to study exoplanet atmospheres - and to find the building blocks of life elsewhere: http://jwst.nasa.gov/origins.html

Hubble Telescope Detects 'Sunscreen' Layer on Distant Planet!

Researchers using NASA's Hubble Space Telescope have detected a stratosphere and temperature inversion in the atmosphere of a planet several times the mass of Jupiter, called WASP-33b. Earth's stratosphere sits above the troposphere, the turbulent, active-weather region that reaches from the ground to the altitude where nearly all clouds top out. In the troposphere, the temperature is warmer at the bottom — ground level — and cools down at higher altitudes. The stratosphere is just the opposite: There, the temperature rises at higher altitudes. This is called a temperature inversion, and it happens because ozone in the stratosphere absorbs some of the sun's radiation, preventing it from reaching the surface and warming this layer of the atmosphere. Similar temperature inversions occur in the stratospheres of other planets in our solar system, such as Jupiter and Saturn. But WASP-33b is so close to its star that its atmosphere is a scathing 10,000 degrees Fahrenheit, and its atmosphere is so hot the planet might actually have titanium oxide rain. http://hubblesite.org/newscenter/archive/releases/2015/25/

The James Webb Space Telescope will help us to characterize the atmospheres of extrasolar

Charting the Milky Way from the Inside out - using infrared light! http://www.nasa.gov/jpl/charting-the-milky-way-from-the-inside-out

In this artist's concept it seems that Sagittarius arm further splits into two arms...and our sun is located in the outer branch of Sagittarius arm....

It's not just #JWST flight hardware that needs protection from contaminants - the equipment we use to test our flight hardware also needs special care. Read more: http://www.nasa.gov/feature/goddard/nasa-technology-protects-webb-telescope-from-contamination

Ever wonder what it's like to be an astronomer? Dr. Amber Straughn talks about her cool job. (Her part is 33 min in.) http://www.worldsciencefestival.com/programs/cool-jobs/

#JWST will help us better understand how interacting galaxies affect each other. This image  #Hubble shows NGC 7714 and presents an especially striking view of the galaxy's smoke-ring-like structure. The golden loop is made of sun-like stars that have been pulled deep into space, far from the galaxy's center.

The universe is full of such galaxies that are gravitationally stretched and pulled and otherwise distorted in gravitational tug-o'-wars with bypassing galaxies.

The companion galaxy doing the "taffy pulling" in this case, NGC 7715, lies just out of the field of view in this image. A very faint bridge of stars extends to the unseen companion. The close encounter has compressed interstellar gas to trigger bursts of star formation seen in bright blue arcs extending around NGC 7714's center.

The gravitational disruption of NGC 7714 began between 100 million and 200 million years ago, at the epoch when dinosaurs ruled the Earth.

Intelligent life busted the accretion disc. I gotta writem a ticket.

Here NASA Administrator Charles Bolden poses with  #JWST's full-scale engineering test sunshield while on a visit to Northrop Grumman.  Yep, our sunshield really is that big! (It's about the size of a tennis court...)

(Bolden is in the center where the telescope will be.  The sunshield is folded up here, but you can get an idea of the scale of the length of it.  There is a smaller model of the sunshield just to the right of center in the background.)

+James Webb Space Telescope (JWST) it is THIS kind of thing that I want my tax dollars going to - not some obscene war. Money superbly spent. I can't wait till it's in orbit & taking amazing images & expanding all of our knowledge.

All about the next generation James Webb Space Telescope!
Introduction

The James Webb Space Telescope is the successor to Hubble. It is an infrared telescope with a 6.5m mirror and a sunshade the size of a regulation tennis court! It will launch in 2018.
