NASA has released a recent James Webb Space Telescope (JWST) photo of the Hercules galaxy as a “preview” of the observatory’s first full-color image on July 12, and it looks gorgeous.
In addition, officials have given a list of the first showings, an international team of scientists from NASA, the European Space Agency (ESA), the Canadian Space Agency (CSA) and the Maryland Space Telescope Science Institute (which manages the observatory). selected by the committee.
The group’s leaders promise the images will reveal “unprecedented” detailed human observations of some of the deepest areas of the universe.
IT House learned that this photo was taken by the “Fine Guide Star Sensor” (FGS) and a near-infrared camera mounted on the telescope, with a cumulative exposure time of 32 hours. The sharpest and most distant infrared deep space cosmic image ever obtained.
The main purpose of the FGS is an instrument that allows the telescope to be pointed precisely. Essentially, it helps Webb aim its target and keep it in orbit. NASA called the FGS observations of stars and galaxies “a tantalizing glimpse into what the telescope’s science instruments will reveal in the weeks, months and years to come.”

Popular Science: The James Webb Space Telescope, the successor to NASA’s Hubble, launched on December 25, 2021, on a mission to study the oldest stars and take an “unprecedented” look into the universe’s past.
Webb is currently at Lagrange Point 2 (L2), its observation site, which is nearly 1 million miles (1.6 million kilometers) away. It is the largest and most powerful space telescope ever launched by humans.
The first list of full-color images from the James Webb Space Telescope includes:
Carina Nebula: One of the brightest nebulae in the sky, simply a cloud of gas and dust, located near the constellation Keel in the southern part of Carina, about 7,600 light-years from Earth. The Carina Nebula is home to the famous “Pillars of Doom” (slender finger-like structures of cosmic gas and dust).
WASP-96 b: This is a huge, extremely hot exoplanet, the first known planet to have a completely cloudless atmosphere, WASP-96 b is also the first discovered by scientists to have a super-intense sodium Elemental character of planets. The planet’s mass is quite similar to that of Saturn, so the researchers classified it as a “hot Saturn.”
The Orion Nebula: A cloud of expanding gas surrounding a dying star, known to astronomers as the Southern Ring Nebula or the Eight-Burst Nebula (Eight-Burst Nebula), about 2,000 light-years from Earth.
Stephen’s Quintet: This is a group of galaxies about 280 million light-years from Earth, where member galaxies collide with each other, shining brightly for millions of years. Located in the constellation Pegasus, this compact group of galaxies consists of five galaxies, four of which are tightly bound together and are expected to merge with each other.
SMACS J0723.3-7327: No further information was found. Officials say that the James Webb Space Telescope will use gravitational lensing to magnify and “bend” light from nearby galaxies to obtain such extremely distant and faint galaxies deep field view.
