The full-scale  #JWST pathfinder (test version of our backplane) shown going into NASA Johnson's huge Chamber A for cryogenic testing. You can see the two spare primary mirror segments (one gold, one silver) mounted on it - the boom that holds the secondary mirror is fully extended.  #TechTuesday

Jason Kalirai will give a free public lecture on #Hubble & #JWST on April 1st at the National Academy of Sciences in Washington, DC.  More info on the event and how to register: http://sites.nationalacademies.org/ssb/ssb_153311  

If you're not in DC and can't make it, there is a livestream:

Future #JWST observations will complement those of #Hubble - like this detailed view of star birth in the beautiful curves of nearby spiral galaxy M83. http://hubblesite.org/newscenter/archive/releases/2009/29/image/b/

Happy Monday! In case you missed  it, here's a "smile" for your day, captured by #Hubble: http://www.nasa.gov/content/hubble-sees-a-smiling-lens/#.VOeZ1sZBHDO

In the center of this image, taken with the NASA/ESA Hubble Space Telescope, is the galaxy cluster SDSS J1038+4849 — and it seems to be smiling.

You can make out its two orange eyes and white button nose. In the case of this “happy face”, the two eyes are very bright galaxies and the misleading smile lines are actually arcs caused by an effect known as strong gravitational lensing.

Galaxy clusters are the most massive structures in the Universe and exert such a powerful gravitational pull that they warp the spacetime around them and act as cosmic lenses which can magnify, distort and bend the light behind them. This phenomenon, crucial to many of Hubble’s discoveries, can be explained by Einstein’s theory of general relativity.

In this special case of gravitational lensing, a ring — known as an Einstein Ring — is produced from this bending of light, a consequence of the exact and symmetrical alignment of the source, lens and observer and resulting in the ring-like structure we see here.

Hubble has provided astronomers with the tools to probe these massive galaxies and model their lensing effects, allowing us to peer further into the early Universe than ever before. This object was studied by Hubble’s Wide Field and Planetary Camera 2 (WFPC2) and Wide Field Camera 3 (WFC3) as part of a survey of strong lenses.

A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Judy Schmidt.

Today at 1pm EDT, #JWST scientist @astraughnomer will be doing a Twitter Q&A on #AskAstraughnomer for @NASApeople!

(If any of you G+ folks are on Twitter, come check it out!)

The James Webb Space Telescope will be able to look further back in time than we have ever seen.

So how long before it gets up? Astronomy is so out of date they really need this update badly. And how much space and distance will it cover by itself?

The shamrock can symbolize life and rebirth. Here is star birth within dust, shown green in this infrared view from NASA's WISE satellite: http://go.nasa.gov/1BuEm64

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.
