James Webb Telescope: NASA set to make history

NASA Administrator Bill Nelson said Wednesday that the agency will release “the deepest image of our universe ever taken” on July 12 for the newly launched James Webb Telescope.

NASA Administrator Bill Nelson said Wednesday that the agency will release “the deepest image of our universe ever taken” on July 12 for the newly launched James Webb Telescope.

“If you think about it, it’s much more than humanity has ever seen before,” Nelson said during a press briefing at the Space Telescope Science Institute in Baltimore. Miles (1.5 million kilometers) orbiting the sun.

A marvel of engineering, the James Webb Space Telescope is able to look at the universe more than any of its predecessors, thanks to its huge primary mirror and its instruments that focus on infrared, allowing it to see through dust and gas.

“It is going to explore the atmospheres of solar objects and exoplanets orbiting other stars, giving us clues as to whether their atmospheres are similar to ours,” Nelson added, speaking by phone while parting with Kovid.

“It could answer some of the questions we have: Where did we come from? What else is there? Who are we? And of course, it’s going to answer some questions that we don’t even know what the questions are.”

The infrared power of the web allows it to see more deeply during the Big Bang, which occurred 13.8 billion years ago.

As the universe expands, the light from the oldest star emits ultraviolet and visible wavelengths, longer infrared wavelengths – which the web is equipped to detect at unprecedented resolutions.

Currently, the oldest cosmic observations are within 330 million years of the Big Bang, but with the power of the web, astronomers believe they will easily break the record.

– 20 years of life –

In even better news, NASA Deputy Administrator Pam Melroy revealed that, thanks to an efficient launch by NASA partner ArianaSpace, the telescope could be in operation for 20 years, more than double what was originally envisioned.

“Not only will those 20 years let us go deeper into history and time, but we can go deeper into science because we have the opportunity to learn and grow and make new observations,” he said.

NASA also wants to share the first spectroscopy of the web of a distant planet on July 12, known as an exoplanet, says NASA’s top scientist Thomas Zurbuchen.

Spectroscopy is a tool for analyzing the chemical and molecular structure of distant objects and can help determine the atmosphere and other features of a planet’s spectrum, such as whether it contains water and its terrain.

“From the beginning, we look at this earth that keeps us awake at night when we look up at the starry sky and wonder if we’re looking there, is there life elsewhere?” Jurbuchen said.

Nestor Espinoza, an STSI astronomer, told AFP that previous exoplanet spectroscopies using existing instruments were very limited compared to what the web could do.

“It’s like living in a room that is very dark and you only have one small pinhole that you can see,” he said of current technology. Now, with the web, “You have opened a huge window, you can see all the small details.”
