Surprise announcement from NASA and the White House — the first JWST (James Webb Space Telescope) image will be unveiled today by President Biden and VP Harris in a ceremony today at 5:00 5:30 p.m. EDT.

The other 4 images will be released tomorrow at 10:30 a.m. EDT.

x We can't contain the excitement for @NASAWebb's first full-color images!



On Monday, July 11 at 5pm ET (21:00 UTC), President Biden will unveil one of the space telescope's first images of deep space as a preview of what's ahead: https://t.co/kP5JdQEpVz pic.twitter.com/1wFZGkqrx8 — NASA (@NASA) July 11, 2022

The image to be unveiled today is called “Webb's First Deep Field". It is likely to show light from some galaxies or stars whose light has traveled over 13.5 billion years, less than 0.3 billion years after the Big bang, perhaps even earlier than that.

It will be comparable to the Hubble Ultra Deep Field image from 2009, but using infra-red wavelengths and probably showing fainter and more distant objects.

From www.nasa.gov/…, the 5 objects are — Carina Nebula. The Carina Nebula is one of the largest and brightest nebulae in the sky, located approximately 7,600 light-years away in the southern constellation Carina. Nebulae are stellar nurseries where stars form. The Carina Nebula is home to many massive stars, several times larger than the Sun.

Stephan’s Quintet: About 290 million light-years away, Stephan’s Quintet is located in the constellation Pegasus. It is notable for being the first compact galaxy group ever discovered in 1877. Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters.

Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters. Southern Ring Nebula. The Southern Ring, or “Eight-Burst” nebula, is a planetary nebula – an expanding cloud of gas, surrounding a dying star. It is nearly half a light-year in diameter and is located approximately 2,000 light years away from Earth.

WASP-96 b (spectrum). WASP-96 b is a giant planet outside our solar system, composed mainly of gas. The planet, located nearly 1,150 light-years from Earth, orbits its star every 3.4 days. It has about half the mass of Jupiter, and its discovery was announced in 2014. Here are images of four of the five cosmic objects as taken by Hubble, in visible and near-infrared wavelengths. All are spectacular looking images, hence we wait with bated breath for JWST’s versions of these objects. The SMAC 0723, a galaxy cluster 5 billion light years away, was imaged by Hubble and shows clear examples of gravitational lensing (the arcs), which allows extremely distant and faint objects to be observed. This is likely the target whose image will be released today. This is the current record holder for the most distant galaxy imaged, although it will take JWST to confirm and better characterize it - x Far, far away: Astronomers reveal most distant galaxy on record



Galaxy HD1 is 13.5 billion light-years away and may be home to first stars in the universe — or a black hole about 100 million times the mass of the sun.

The near-infrared wavelength image on the right, also by Hubble, reveals stars and galaxies behind the dust clouds. JWST’s IR-wavelength images will be similar to the one on the right, with fainter and deeper objects. The 5th object is exoplanet WASP-96b, whose image will be a spectra graph, similar the one below (exoplanets are too small to be directly imaged). Such spectroscopy will enable identification of molecules and signatures of life in the atmosphere of exoplanets. https://t.co/V3HUPP61Ey The Early Universe From webb.nasa.gov/… — For the first few 100K years after the Big Bang, the Universe was filled with protons, neutrons, and electrons free from each other. Any photons would get scattered by the electrons, making that period dark and opaque.

As the Universe cooled down, 240K to 300K years after the Big Bang, in a process called "Recombination", protons, neutrons and electrons combined into atoms of hydrogen and deuterium. Light could now travel far distances but there were no strong sources of light like stars.

This “Dark Age” ended around 300M years after the Big Bang, as atoms clumped into stars, whose light could travel vast distances. It was a violent universe, where some stars exploded into Supernova while heavier elements, more stars, galaxies, and black holes were formed.

JWST will uniquely be able to explore this space-time of the Universe, 100M to 250M (0.1B to 0.25B) years after the Big Bang (as well as other regions closer to earth).

Light from that era is “red-shifted” (their wavelengths get stretched out) due to the expansion of space itself; hence, the need for a telescope that can observe in infra-red wavelengths Illustration of how far back in time JWST will be able to see Links to tomorrow’s events -
