Our view of the universe has just expanded. The first image from NASA’s new space telescope, released on Monday, floods the galaxy and provides the deepest look of the universe ever captured.
The first image from the $ 10 billion James Webb Space Telescope is the farthest we’ve ever seen, both in time and distance, near the dawn of time and the edge of space. Following that image, four more galaxy beauty shots will be released on Tuesday from the telescope’s first outward gaze.
The image of the “deep universe” released at the White House event is full of stars, with huge galaxies in the foreground, peeking through faint and very distant galaxies here and there. Part of the image is light from a not-so-long place from the Big Bang 13.8 billion years ago.
A few seconds before announcing it, President Joe Biden said, “The oldest recorded light in the history of the universe over 13 billion years ago-let me say it again-13 billion years ago. It’s hard to understand. I was amazed at the image that said. “
Bill Nelson, NASA’s administrator, said that busy images with hundreds of white, yellow, orange, and red spots, streaks, spirals, and swirls are “just a few spots in the universe.”
Tuesday’s tap photo shows a view of a giant gaseous planet outside the solar system, two images of a nebula where stars are born and die in spectacular beauty, and a classic image of five dense galaxies dancing to each other. Includes updates for.
The world’s largest and most powerful space telescope soared from French Guiana in South America last December. In January, we reached the observatory one million miles (1.6 million kilometers) from the earth. A long process then began aligning the mirrors, allowing the infrared detector to cool sufficiently to operate and calibrate the scientific instrument. All of these are protected by a tennis court-sized awning that keeps the telescope cool.
Using a telescope to look so far, scientists can get a glimpse of the early days of the universe about 13.7 billion years ago, focus more on objects in the universe closer, and even on our own solar system. I plan to zoom in.
The Webb is considered the successor to the highly successful but dilapidated Hubble Space Telescope. Hubble has been staring at it until 13.4 billion years ago. In 2016, we discovered the characteristics of very bright galaxy light waves. Astronomers measure how far back a light-year looks at 5.8 trillion miles (9.3 trillion kilometers).
“Webb can go back to just after the Big Bang and look for galaxies so far away that it took billions of years for light to reach the telescope from those galaxies,” said Jonathan, a deputy project scientist at Webb. Gardner said. During media briefing.
How long ago did the first image look? Project scientist Klaus Pontoppidan said last month that astronomers would make complex calculations to figure out how old those galaxies are in the coming days.
“The images are brilliantly deep (than similar images taken by Hubble), but it’s unclear how far back they are,” Richard Ellis, a professor of astrophysics at the University College London, said in an email. ..
The deepest view of the universe is “not a very long-lasting record,” said Pontopidan, as scientists are expected to go deeper with the Webb Telescope.
Thomas Zurbuchen, NASA’s chief science mission, said so when he saw the images he became emotional.
The 21-foot (6.4-meter) web gold-plated flower-shaped mirror is the largest and most sensitive to date in space. It consists of 18 segments, one of which was hit by a larger than expected micrometeorite in May. The previous four micrometeorite impacts on the mirror were small. Despite its impact, according to NASA, telescopes continue to exceed mission requirements with little data loss.
NASA is working with European and Canadian space agencies on Webb.
“This dramatic advance is now really exciting to reach the ultimate award for many astronomers like me. It is the moment when the universe was first exposed to the starlight.” It’s about identifying the “dawn,” Ellis said.
