In a live stream from Nasa TV, Biden was able to present the first colorful result from a telescope that astronomers around the world have high expectations of.

The brand new space telescope can look further than any other instrument, and can literally look all the way back to the dawn of time. Illustration of “James Webb” in space. The yellow mirror is composed of 18 hexagonal parts. Illustration: Adriana Manrique Gutierrez / NASA GSFC / CIL Sees the first galaxies “James Webb” captures light in the infrared spectrum. Infrared light is also called heat radiation. From the childhood of the universe, over 13 billion years ago, only infrared light reaches our solar system. The super telescope can see what happened just 200 million years after “The Big Bang”, when the universe originated. This means that it can look back to the time when the first galaxies were formed. “The Big Bang”, the big bang Photo: Jørgen Berntsen Leangen / news The event when our universe began to expand, and which happened about 14 billion years ago. The astronomers’ models are not able to say anything about what the universe was like before this event, or whether there was any universe at all before the big bang. The term “big bang” was first used by the British astrophysicist Fred Hoyle in a BBC radio program in 1949. Today’s description of the universe’s evolution from the big bang onwards is constructed using Albert Einstein’s theory of relativity. Measurements have shown that the universe is expanding, and that it is getting colder and colder. 14 billion years ago, the universe was in a state of extremely high density and temperature.

For Dahle, the images that eventually come from the space telescope become important for further research. – It will be able to give us the story of how the universe has evolved, from the stars were lit until today, Dahle told news. Together with colleagues from several countries, he will try to find out what happened when the first stars appeared 10 billion years ago. The mirror for “James Webb” is 6.5 meters in diameter and made of the metal beryllium. Photo: Nasa Expensive binoculars The road ahead of the space telescope “James Webb” has been both tortuous and long. The development of the hyper-advanced binoculars has taken 25 years. In the first plans, the launch of the telescope was to take place as early as 2007. Since then, the launch has been postponed many times. The cost overruns have been huge, and the total price for the telescope is now estimated at close to NOK 100 billion. The James Webb telescope’s long journey towards space NASA begins planning for the new telescope. It is then called the Next Generation Space Telescope, but will later change its name to James Webb, after the man who was chief executive of Nasa in the 1960s. Originally, the telescope was to cost NOK 4.5 billion. but has over time become far more expensive. The price ended at 100 billion kroner, according to the New York Times. The telescope is scheduled to be launched in 2007, but will be postponed for the first time. This is the first of many postponements. A mix of technical issues, political hesitation and project management issues have all contributed to countless delays.

The launch is postponed once again, this time due to technical problems. Later that year, an independent review committee recommends that the launch be moved to March 2021. Like many other planned events, the James Webb telescope’s propulsion is also affected by the corona, and in July 2020, NASA announced a new launch date October 31, 2021. The huge Ariane the rocket, which will carry the telescope into space, is not finished. This means that the launch date will be moved to November / early December 2021. Later that year, NASA and ESA will announce another delay since the observatory has not yet been sent to the launch site at Kourou in French Guiana. New date will be December 18, but bad weather puts an end to this time as well.

Photo: Chris Gunn / NASA The James Webb Space Telescope has found its parking space in space, just over 1.5 million kilometers from Earth. The telescope will try to capture rays from stars and galaxies that were formed over 13 billion years ago, to gain greater insight into the past. After just over two months in space, Nasa can report that everything is fine. The telescope has provided a test image of the star called TYC 4212-1079-1, which is more than astrophysicists had dared to hope for. – This is first and foremost a proof that the telescope works properly, and now there are probably many who have drawn a sigh of relief. Things you see in this picture give us a hint about what the telescope will be able to deliver in the long run, says researcher Håkon Dahle to news. Photo: NASA Show more The Space Telescope is a collaboration between Nasa, the European Space Agency and ESA. On the first day of Christmas last year, the telescope was finally launched. The journey to the destination took almost a month. After a series of complicated maneuvers on its way through space, “James Webb” has found its place, 1.5 million kilometers from Earth. More images are on the way The telescope is now in a small orbit around a place called Lagrange point 2. At this point, gravity is equalized from the sun and the earth, so that “James Webb” can hold its position. The time that has passed since the space telescope came into place this winter has been used to fine-tune and calibrate the instruments. The color images from “James Webb” have so far been a well-kept secret. A few single-color test images were published in connection with the calibration of the instruments in February and March. But now far more spectacular images are expected. Some of the few professionals who have seen the color images have been moved by what they have seen. Now the rest of the world will also see this. On Tuesday at 1630, Nasa will publish several of the very first color images on a separate website.
