The Strongest Space Telescope Will Be Sent Into Space In 2018: 70 Times More Than The Hubble

According to informed media reports, NASA is building the strongest in the history of the space telescope, allowing scientists to observe the scene in the early universe after the Big Bang, which is a telescope is named "James Webb" telescope. Is the successor to the Hubble Space Telescope, Hubble has been in service for 25 years, the last few years has been close to the length of service, NASA and international partners hope to be able to replace the Hubble telescope Webb, of the universe of deep space to conduct a more in-depth observations .

James Webb (JWST) telescope is expected to launch in October 2018, using the European Ariane rocket, currently the telescope project cost reached $ 8.8 billion, far more than the budget of $ 3.5 billion. JWST Space Telescope is a powerful time machine, to the birth of the universe can be observed after the first galaxies, JWST Space Telescope program scientist Mark believes that the telescope can observe the early universe, dark space, where being born first stars in the universe .

JWST Space Telescope weighs 6.4 tons, the primary mirror diameter of 6.5 meters, is about three times the Hubble Space Telescope, NASA telescope Builder, the European Space Agency and the Canadian Space Agency. JWST Space Telescope carries four high-tech equipment, can capture objects extremely weak signals.

JWST space telescope in the infrared band observations of the universe, and the camera shutter time can be further extended this capability helps to extremely faint objects imaged. According to scientists estimate, JWST Space Telescope dim light gathering capacity is 70 times the Hubble telescope, which is the basis of our study of the history of the universe.

In addition to observing the universe, JWST Space Telescope is also able to detect extrasolar planets, NASA in 2009 launched the Kepler telescope, helping scientists to detect thousands of exoplanets, JWST Space Telescope will also promote this plan, find more distant exoplanets.

If Kepler telescope system can only detect the presence of extrasolar planets, then the JWST Space Telescope's more powerful features can be observed on exoplanets, spectral signal exoplanet research, to understand its atmospheric composition. JWST Space Telescope will be fixed in the L2 point (one point Lagrange), and approximately 1.5 million kilometers away from us, more discoveries will appear later in 2018. Scientists believe that if the results of the Hubble Space Telescope observations of change all the textbooks, then the space telescope JWST will once again rewrite our textbooks.
