"Just in time for Christmas, HubbleSite has released a Hubble Ultra Deep Field redux. The original was in visible light; this version, five years on, is in infrared (1.05, 1.25 and 1.6 um).
The observation is in support of the upcoming JWST, which will observe exclusively in infrared, but the newly installed WFC3 does seem to provide some extra resolution over the 2004 visible observations with WFC2."

"Less than four months from now, India's first stealth fighter will fly for the first time. It is called the Fifth Generation Fighter Aircraft, or FGFA, and is being developed in Russia by Sukhoi. Several of the technologies being developed for the stealth fighter have evolved from those used in the Sukhoi 30 MKI. Considered the most maneuverable fighter in the world, the Sukhoi 30 MKI uses thrust vectored engines, which deflect the exhaust from its engines to extreme angles, enabling the jet to pull off violent maneuvers like a flat spin — where the jet literally spins around on its axis."
