NASA releases teaser image from James Webb Space Telescope

NASA shared a “teaser” image ahead of the long-awaited release next week of the first images of deep space from its James Webb Space Telescope.

The $10bn (£7.4bn) observatory has been launched to peer back into the dawn of the universe and capture what happened just a couple of hundred million years after the Big Bang.

Its first science-quality photos are due for release on July 12, but the US space agency has provided a photo of engineering testing as a small preview.

The image is the result of 72 exposures over 32 hours and shows a selection of distant stars and galaxies.

NASA said in a statement that it has some “rough” qualities, but is still “one of the most profound images of the universe ever taken” and offers a “teasing look” at what’s to come. weeks, months and years.

“When this image was taken, I was thrilled to see all the detailed structure of these dim galaxies,” said Neil Rowlands, software scientist for the Webb Fine Guidance Sensor at Honeywell Aerospace.

James Webb Space Telescope Instruments

NIRKam (near infrared camera) thermal imager from the edge of the visible to the near infrared.

NIRSpets (near infrared spectrograph) will also perform spectroscopy in the same wavelength range.

MIRI (Mid-InfraRed Instrument) will measure the mid to long infrared wavelength range from 5 to 27 micrometers.

FGS / NIRISS (fine pointing sensor, near infrared imager and slitless spectrograph) is used to stabilize the line of sight of the observatory during scientific observations.

Jane Rigby, Webb Scientist at NASA’s Goddard Space Flight Center, said “the faintest spots in this image are exactly the types of faint galaxies that Webb will study in his first year of science.”

The astronomers have previously said the first images are “sure to make a welcome impression” when they are unveiled next week.

NASA added that it will be “a unique moment for all of us to stop and marvel at a view that humanity has never seen before.”

The US space agency leading the Webb project previously released a set of engineering images to demonstrate that all the hardware of the new astronomical superspace telescope is working properly.

These images show slightly different views of the Large Magellanic Cloud, a small satellite galaxy of our Milky Way, but it’s unclear what the first full-color images will capture.

Webb went through a six-month preparation period before he could begin scientific work, calibrating his instruments to suit the space environment and aligning his mirrors.

It was launched into space on December 25 last year and later went into orbit a million kilometers from our planet.

Scientists hope the observatory — a replacement for the 32-year-old Hubble telescope — will be able to look back 13.5 billion years to a point just 100 to 200 million years from the Big Bang.

It has an ambitious mission: to study the early universe, find out how fast it is expanding now, and analyze objects across the cosmos, from galaxies to exoplanets.

The telescope has the famous golden mirror, which consists of 18 individual hexagonal segments, each of which controlled by seven actuators that provide precise movement and focus.

In February, NASA released the first-ever images of James Webb.  The result was a mosaic of 18 randomly arranged dots of starlight (pictured), the product of misaligned Webb mirror segments, all of which reflect light from the same star back onto its secondary mirror.

They had to be deployed slowly and carefully over the past six months to prepare James Webb for his scientific mission.

NASA administrator Bill Nelson said last week that Webb will be able to see further into space than any other telescope before him.

“It will examine objects in the solar system and the atmospheres of exoplanets orbiting other stars, which will give us clues as to whether their atmospheres are potentially similar to ours,” he said.

“It might answer some of the questions we have: Where do we come from? What else do you have? Who are we?

“And, of course, he will answer some questions that we don’t even know what those questions are.”

Webb’s infrared capabilities allow him to see into the past before the Big Bang, which happened 13.8 billion years ago.

As the universe expands, light from the earliest stars shifts from the ultraviolet and visible wavelengths in which it was emitted to longer infrared wavelengths.

Astronomers will use the Webb to observe the infrared universe, analyze the collected data, and publish scientific articles about their discoveries.

In addition to what is already planned for Webb, there are unexpected discoveries that astronomers cannot foresee.

James Webb's primary mirror consists of 18 hexagonal segments of gold-plated beryllium metal and is 21 feet 4 inches (6.5 meters) in diameter.  It is supported by three shallow carbon fiber tubes or struts that extend from the large primary mirror.

In 1990, when Hubble was launched, dark energy was completely unknown. Now it is one of the most interesting areas of astrophysics.

Now scientists are eagerly awaiting what secrets James Webb might reveal and what it could mean for our understanding of the universe.

Described by NASA as the premier space science observatory of the next decade, Webb will primarily observe space in the infrared spectrum, allowing him to see through clouds of gas and dust where stars are being born.

By comparison, its predecessor, Hubble, has operated primarily in the optical and ultraviolet ranges since its launch in 1990.

Webb is about 100 times more powerful than Hubble, allowing it to observe objects at greater distances, that is, further in time than Hubble or any other telescope.

NASA prefers to think of James Webb as Hubble’s successor rather than his replacement, as the two will work in tandem for a while.

Currently, the earliest cosmological observations date back to within 330 million years of the Big Bang, but astronomers believe that with Webb’s capabilities, they will easily break the record.

James Webb began development in 1996 and was originally scheduled to launch in 2007, but a major upgrade in 2005 brought it back, and a series of further delays saw it eventually enter orbit late last year.

JAMES WEBB TELESCOPE

The James Webb Telescope has been called a “time machine” that can help unravel the mysteries of our universe.

The telescope will be used to look back at the first galaxies born in the early universe more than 13.5 billion years ago and observe the sources of stars, exoplanets and even our solar system’s moons and planets.

The huge telescope, already worth over $7 billion (£5 billion), is said to be the successor to the Hubble Orbiting Space Telescope.

The James Webb telescope and most of his instruments have an operating temperature of approximately 40 Kelvin – about minus 387 Fahrenheit (minus 233 Celsius).

It is the world’s largest and most powerful orbiting space telescope, capable of looking back 100-200 million years after the Big Bang.
