Webb’s First Deep Field is trending in the science and space news community and everyone is excited for the first images from the James Webb space telescope which will be shared on the 12th of July by NASA . JWST is designed to discover and unveil the truth of deep universe secrets. The new space telescope has four major optical components. These instruments help scientists to take more clear pictures from the James Webb telescope. This latest infrared-optimized large mirror telescope is developed to study the earliest periods of the universe. So, in this episode of the James Webb telescope series, we’ll cover Webb’s First Deep Field and how the newly designed advanced jwst will study the earliest period of the universe? how do scientists take images of the cosmic universe that we can’t see till now even with Hubble? Metroid attack risks? How and when can you watch the Webb’s First Deep Field broadcast live ? Much more.
James Webb Telescope Will Study The Earliest Periods Of The Universe
James Webb is the world’s most powerful telescope developed by the partnership between NASA, ESA, and CSA. The new Webb can look back in the universe when the first galaxy and stars started to form (100 Million years after the Big Bang). However, the Hubble telescope which is the second most powerful after the new space telescope can see up to 13 billion light-years away. We have already covered the scientific capabilities of the new space telescope. All the James Webb space telescope pictures ( Webb’s First Deep Field ) will be taken in infrared mode and then converted into a high quality colorful attractive image through software. Nasa has shared that the first images from the James Webb space telescope will be broadcast on 12th July 2022 we call it Webb’s First Deep Field or JWST Deepest View. European Space Agency (ESA) has invited everyone in Europe to attend the broadcast event of First Images from the James Webb Space Telescope.

ESA has tweeted– “#EuropeMeetsWebb On 12 July, #Webb’s First Deep will release its first full-color images. We’ve invited you to join the celebrations & the community has responded with public events all across Europe.”
How the Pictures from James Webb Telescope will Study The Earliest Periods Of The Universe?
James Webb telescope is an infrared optimized observatory. It will take pictures of the objects and universe in infrared mode and then with the help of software, scientists will convert the image into a colorful image. This will be the process of getting Webb’s First Deep Field pictures for common humans. Now the answer to the question- “How James Webb Telescope Will Study the Earliest Period of the Universe?” lies within this process of capturing Infrared lights.
How James Webb Sees Things that We can’t: “Red-Shift” Effect-
In simple words, As light travels a longer distance, the wavelength of the light is split into different colors and the red color has the highest wavelength. If you see a natural light source it will look white and bright but as far you travel a longer distance from the object the color of the light source started changing and at a maximum distance only red color exists in visible light. This is called the “red shift” in science.
In the universe, Scientists use the same technique of redshift to calculate the distance of stars that are light-years far from the earth. But visible light has limitations and at a certain maximum distance, it also disappears because of the maximum redshift.
Nasa explains that after a certain larger distance like when the first stars were born and galaxy formation started, the wavelength of light expanded as much as the visible light shifted into the near- and mid-infrared electromagnetic spectrum. This was the major reason why NASA needed a very powerful observatory like James Webb Telescope.
The Large Mirror Size will Play a Major Role in Webb Telescope Images and Webb’s First Deep Field
The new space telescope has a total of 18 hexagonal mirrors with a 6.5-meter primary mirror. All the mirrors are made with beryllium which is strong yet light, perfect for the observatory. These mirrors have a layer of thin (100 nanometers) gold which is used not for fashion and design purposes but useful for reflecting more light.
Recently ESA tweeted– “Because #Webb is the largest & most complex space observatory, it has needed 6 months to calibrate its instruments & align its mirrors.”
The size of the mirrors is very large and combinable which helps Webb to capture more infra-red rights to take a clear picture of stars and galaxies. Webb’s official Twitter shares that the 2nd (MIRI) out of four optical instruments is ready for science. Mid-Infrared Instrument (MIRI) has two different modes to take pictures: Camera and spectrograph to see the light coming from the source into the mid-infrared spectrum region. This instrument directly detects the exoplanets and study about their host stars.
James Webb Space Telescope was Hit by a Meteoroid?
Between May 23 to May 25, A micrometeoroid hit the primary camera of the new Webb telescope. The Webb was cost around 9.2 Billion Euros, and a minor issue can damage a lot. Space has a hazardous environment. Many meteoroids and other objects can impact the telescope at any time. So, engineers who designed the new Webb, were well are of risk of collision with micrometeoroids.
The head of OTE at James Webb, Lee Feinberg said- “we expected that occasional micrometeoroid impacts would gracefully degrade the telescope’s performance over time.” The degradation process by the hitting of these meteoroids was already expected but recently four inline meteoroids were collide with the primary mirror damaging more than expected. Luckily, Mirror is still working fine and NASA confirms that the spacecraft is working fine.
NASA tweeted: “In late May, Webb sustained a dust-sized micrometeoroid impact to a primary mirror segment. Not to worry: Webb is still performing at a level that exceeds all mission requirements.”
Impact of Metroid Hit on Pictures from Webb’s First Deep Field
Scientists and engineers who designed the telescope were well aware of the Metroid strike on the new space telescope. After the initial inspection, Nasa has confirmed that the telescope is still performing as expected despite a marginal detachable effect in the data. So, what will be the effect on the quality of James Webb space telescope images? The spacecraft is working fine but if the damage gets out of control, the quality and actual data get affected and scientists might receive inaccurate data.
Because despite light wavelength, the angle of light also matters. That can lead the false Webb telescope images with low accuracy. And in the worst conditions, the mission of the observatory got in trouble. Paul Geithner, The technical deputy project manager at NASA said- “We designed and built Webb with performance margin – optical, thermal, electrical, mechanical – to ensure it can perform its ambitious science mission even after many years in space.”
Paul Geithner said- “We always knew that Webb would have to weather the space environment, which includes harsh ultraviolet light and charged particles from the Sun, cosmic rays from exotic sources in the galaxy, and occasional strikes by micrometeoroids within our solar system,”.

“If you think about that, this is farther than humanity has ever moved before,”- NASA administrator Bill Nelson said in a press release last month, “And we’re only beginning to understand what Webb can and will do. It’s going to explore objects in the solar system and atmospheres of exoplanets orbiting other stars, giving us clues as to whether potentially their atmospheres are similar to our own.”
