After more than 10 years of work by more than 200 scientists and engineers, the MIRI instrument (which is short for Mid-InfraRed Instrument), which will fly on the James Webb Space Telescope is ready to be shipped to NASA. This telescope will eventually be the successor to the Hubble space telescope. MIRI, a pioneering camera and spectrograph, is so sensitive it could see a candle on one of Jupiter's moons. Key components of MIRI have been designed and built at the Max Planck Institute for Astronomy in Heidelberg.
The James Webb Space Telescope (JWST) will explore the era of the first stars, trace the assembly of early galaxies and examine in detail the birth of stars and planetary systems and the characteristics of planets around distant stars.
In order to reach its ambitious scientific goals, JWST will not only rely on its 6.5 meter mirror (compared to Hubble's 2.4 meter) but also on a suite of four sensitive instruments. The first of these instruments to be completed, the Mid-Infrared Instrument (MIRI), has today been handed over to NASA in a ceremony at the Institute of Engineering and Technology in London.
MIRI will now be transported to NASA's Goddard Space Flight Center in Maryland in a specially constructed environmental container designed to protect it from moisture and keep the temperature stable. Once there, it will start the long process of integration with the other instruments, two years of testing to ensure that they all function together correctly, and then integration and test with the telescope optics. The launch of the James Webb Space Telescope is scheduled for 2018.

At last we have a cam small in size but can it deliver the sharpest image, in any cam of its size and cost.
For the remaining weeks of winter, Orion, the celestial hunter, is still residing high in the night sky. The prominent line of his three bright belt stars has sparked legends and sky lore in many cultures past and present around the globe.
Keeping pace with the action cam market, Foscam action cam is a great deal.
Having the right gear is important when you’re out at night shooting the stars whether you are with a friend or you are alone.
These cameras sold by Foscam have the ability to provide a clear bright image of the night sky and it is a live feed
This year marks Hubble’s 25th anniversary, and we’re kicking off a year-long celebration with a new look at one of our most iconic images: The Eagle Nebula’s “Pillars of Creation.”
