NASA James Webb Space Telescope to See 6 Quasars Soon!

The NASA James Webb Space Telescope will focus on quasar research later this year.

A quasar is a supermassive black hole that is millions to billions of times the sun's mass and is exceedingly bright and far away.

Quasars are often found near the cores of galaxies, where they feed on material from an accretion disk around them, releasing massive amounts of radiation in the process.

Quasars are among the most luminous things in the cosmos. They create more light than all other stars in the host galaxy combined.

NASA James Webb Space Telescope to Check At 6 Quasars

NASA aims to point James Webb Space Telescope at six of the most distant and luminous quasars known.

Researchers will have to use data from the telescope to investigate the features of quasars and their host galaxies to figure out how they are related during the early stages of galactic evolution.

The quasars will also be used to study the gas in the space between galaxies, notably during a phase known as cosmic reionization, which occurred when the universe was very young and concluded when the cosmos was very young.

Space.com said scientists are interested in knowing more about the epoch of reionization, which is a time of reionization. This period occurred 13 billion years ago, or less than a billion years after creating the universe.

Galaxies at the time were primarily opaque to intense light, making them difficult to see.

According to team members, Webb's capacity to view infrared light will also help with observations during this time period.

It will be especially valuable because the light of the most distant quasars has been significantly stretched due to space expansion.

This effect, known as cosmic redshift, causes light waves to shift to the red or infrared band, where Webb is most suited for studies.

Webb is hoping to see enough light from the quasars to seek for elements heavier than hydrogen or helium, which astronomers refer to as "metals."

How This Telescope Will Examine Quasars

To explore the events, the telescope's exceptional sensitivity to low light and outstanding angular resolution will be put to the test. When the Webb telescope looks far into the universe, it is essentially peering back in time, according to scientists.

Because quasars are so far away, their light began its journey to Earth when the universe was still very young, taking billions of years to reach us.

Slash Gear said the researchers point out that they'll be looking at stuff from a long time ago, not now. All of the quasars studied by the team existed when the universe was less than 800 million years old, or less than six percent of its present age.

From the earliest beginnings of the cosmos, the examination allows researchers to investigate galaxy evolution and supermassive black hole genesis and evolution.
