NASA Infrared Telescope Obtains “Grain of Sand Size” Deepest, Sharpest View of Distant Galaxies

 כִּי-בָרֵךְ אֲבָרֶכְךָ, וְהַרְבָּה אַרְבֶּה אֶת-זַרְעֲךָ כְּכוֹכְבֵי הַשָּׁמַיִם, וְכַחוֹל, אֲשֶׁר עַל-שְׂפַת הַיָּם

“I will multiply your seed as the stars of the heaven and as the sand which is upon the sea-shore…”

(Bereishith 22:17)

This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time.

This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.

The image shows the galaxy cluster SMACS 0723 as it appeared “4.6 billion years ago.” The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe.

The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

NASA Headquarters oversees the mission for the agency’s Science Mission Directorate. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages Webb for the agency and oversees work on the mission performed by the Space Telescope Science Institute, Northrop Grumman, and other mission partners. In addition to Goddard, several NASA centers contributed to the project, including the agency’s Johnson Space Center in Houston; Jet Propulsion Laboratory (JPL) in Southern California; Marshall Space Flight Center in Huntsville, Alabama; Ames Research Center in California’s Silicon Valley; and others.

NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.

  1. Nasa is fake nothing more than a money laundering operation, they do nothing related to space everything they tell us is a lie, why anyone would trust anything the government tells us is baffling

      • We believe in the Rambam that states it’s impossible to land on the moon. If you do a little bit of research you can find many astronauts admitting they never landed on the moon as well as videos of them shooting the “moon landing” in the desert . These videos exist and you can find them with a little digging. after that we can have a discussion if they ever landed on the moon and why they were NEVER able to repeat it in the last 50 years… Google it and you’ll find every silly answer besides for the truth!

        • What does this have to do with people going to the moon? Why would they fake a picture? Of course they are emphasizing pride in themselves rather than being in awe of Hashem. But what strikes me is that if this is really a picture of an area no larger than a grain of sand, when you look at the grain from approximately an אמה plus one טפח, this has great implications for …

          “Whoever destroys a soul, it is considered as if he destroyed an entire world. And whoever saves a life, it is considered as if he saved an entire world.”
          Talmud Yerushalmi (Sanhedrin 4:1 (22a). Also take a look at Pirkei deRabbi Eliezer ch. 47, Eliyahu Rabbah 11, Yalkut Shimoni on Devarim 166.

          You don’t need to Google that.

  2. I do hope that forward thinking frum educators are teaching the accomplishments of the Webb telescope in their science classes. It is a great achievement for all of mankind.
