NASA completed the telescope looking back past 13 billion years

The US Aeronautics Agency (NASA) built James Webb, the world's largest space telescope, scheduled to launch in 2018.

The James Webb Space Telescope has the ability to look past the universe's 13.5 billion years of complete and ready testing, according to Christian Science Monitor. Dear James Webb (JWST) is the Hubble Space Telescope's successor, but has a larger and stronger mirror design. Planned to launch into space over the next two years, the glasses are the result of 20 years of work after repeated delays and financial hardship.

"Today, we celebrate the completion of the telescope and are about to prove it works well," said John Mather, astrophysicist and senior scientist in the JWST project, speaking at the press conference. yesterday. "We have worked hard for two decades and this is the result. We are about to open a whole new area in astronomy."

While Hubble glasses are known for many important discoveries such as the expansion of the universe, JWST will go further through the discovery of the first planets, stars and galaxies born after the explosion. Big Bang more than 13.5 billion years ago with ultra-sensitive infrared camera. JWST's observations not only help researchers understand the origin of the universe but also help find signs of life on another planet.

"We want to know if another planet out there has enough water to form the ocean, and we believe we can do it," Dr. Mather said.

The $ 8.8 billion telescope equipped with Hubble's 2.7-fold mirror surface and powerful sensors can detect weak infrared light 400 times more than the observations of telescopes space now.

Before launch, JWST will be tested at various facilities and the final assembly line in California, USA to ensure the glass can withstand the noise and vibration during takeoff on rocket backs. . Unlike Hubble, JWST will not be repaired after flying to orbit. Scientists hope it can work in orbit for 10 years.

JWST is the result of a partnership between NASA, the European Space Agency (ESA) and the Canadian Space Agency. After launching, JWST will work in tandem with Hubble."Using two space telescopes at the same time actually brings a more comprehensive picture of the universe than using a separate glass," commented Ken Sembach at the Space Telescope Science Institute (STS).
