James Webb Telescope vs Hubble

The primary mirror of the JWST, the Optical Telescope Element, is composed of 18 hexagonal mirror segments made of gold-plated beryllium which combine to create a 6. 5-meter (21 ft; 260 in) diameter mirror that is much larger than the Hubble’s 2. 4-meter (7. 9 ft; 94 in) mirror. Unlike the Hubble, which observes in the near ultraviolet, visible, and near infrared (0. 1 to 1 μm) spectra, the JWST will observe in a lower frequency range, from long-wavelength visible light through mid-infrared (0. 6 to 27 μm), which will allow it to observe high redshift objects that are too old and too distant for the Hubble to observe. The telescope must be kept very cold in order to observe in the infrared without interference, so it will be deployed in space near the Earth–Sun L2 Lagrangian point, and a large sunshield made of silicon- and aluminum-coated Kapton will keep its mirror and instruments below 50 K (−220 °C; −370 °F).

Unfortunately, the various economic troubles which are plaguing Europe has caused ESA to spend less money than before, so many space programs in Europe has halted. However, both in China as well as in India, there are several ambitious programs present, which may cause any one of these nations to send another man to the moon in the next decade. Naturally, only time will tell; but nothing will change the fact that mankind's future is in the stars. Moon Boots are a winter essential. What exactly are they? Moon Boots are a water resistant or water proof form of footwear that are made from lightweight materials with a specialised thermal lining that can keep the feet and calf warm in temperatures reaching -35oC. The heel and sole of the boot enhance comfort and stability while the sole adds extra warmth due to its own insulating property. These features make them ideal in snow and cold weather conditions. Their appearance reflects an oversize, fancy and snug gumboot. The Waxing of the moon, is the period that runs between the New Moon and the Full Moon. The influence it carries during this time is wonderful for building, gathering or creating new things. The waxing moon is a great time to start new projects, sign up for a course, be creatively expressive, anything related to generating new aspects of life, or recreating the old.
