James Webb discovers his first supernova 3 billion light-years away from Earth

The bright light detected by NASA’s James Webb Telescope (JWST) three billion light-years from Earth is believed to be the first $10 billion range observation of a dying star explosion.

Officially known as a supernova, it is the “last hilarious” that occurs when a star runs out of fuel. This results in a pressure drop, as the cosmic body expands to at least five times the mass of our sun — a size of about 333,000 that of Earth — and then explodes, releasing tons of debris and particles.

The starburst occurred in the galaxy SDSS.J141930.11 + 5251593, where JWST took images showing body light becoming faint for five days – evidence that sparked the supernova theory.

What’s also exciting is the fact that JWST was not designed to find and detect new passersby, Mike Engeser of the Space Telescope Science Institute (STScI), told Inverse who first reported the discovery.

Not only did James Webb spot a supernova, but astronomers were baffled by the discovery because the telescope is not designed to find dying stars.

The potential supernova was captured using the NIRCam instrument designed to detect light from the oldest stars and galaxies using a wide range of infrared light.

Equipped with coronal instruments, the NIRCam is instruments that allow astronomers to take pictures of very faint objects around a centrally bright object, such as stellar systems or in this case, stellar eruptions.

JWST was investigating the distant galaxy, so the supernova capture was by luck, Engeser told Inverse.

The dying star, which appears as a small bright spot in images, was not present in images of the galaxy taken by the Hubble Space Telescope in 2011.

The team used software to analyze James Webb's image

The program then looked at the image of the galaxy that Hubble took in 2011 to see if there was anything different

The team used software to analyze a James Webb image against the same image taken by Hubble in 2011, which is how they identified the tiny bright light.

Engesser and his team used software designed to detect differences in images that led to a bright spot.

JWST proved to be money well spent even just a week after its launch. Not only did it hand over its first official images of deep space on July 12, but a week later scientists announced that it had revealed a 13.5-billion-year-old galaxy that is now the oldest in the universe visible to human eyes.

The galaxy, called GLASS-z13 (GN-z13), formed just 300 million years after the Big Bang 13.8 billion years ago.

The previous record holder, discovered by the Hubble telescope in 2015, was GN-z11 dating back 400 million years after the birth of the universe.

JWST captured a look at GN-z13 using the Near Infrared Camera (NIRCam) instrument, which is capable of detecting light from the oldest stars and galaxies.

While investigating the area is GN-z13, JWST also spotted GN-z11.

Scientists from the Harvard and Smithsonian Center for Astrophysics in Massachusetts note that although both are ancient, each galaxy is very young, according to a New Scientist report.

GN-z13 is about 1,600 light-years across and GLASS z-11 spans 2,300 light-years.

This is compared to our own Milky Way, which is about 100,000 light-years across.

The paper published in arXiv notes that both galaxies have the mass of a billion suns, because they formed so soon after the Big Bang.

The team suggests that this happened when galaxies were growing and devouring stars in the region.

The researchers shared in the research paper: “These two objects are already setting new constraints on the evolution of galaxies in the era of cosmic dawn.

They point out that the discovery of GNz11 was not just a matter of good fortune, but that it is likely that a group of ultraviolet-luminous sources with very high star-forming efficiency is capable of assembling.

James Webb Telescope: NASA’s $10 billion telescope built to detect light from the oldest stars and galaxies

The James Webb Telescope has been described as a “time machine” that could help unlock the secrets of our universe.

The telescope will be used to look at the first galaxies born in the early universe more than 13.5 billion years ago, and observe the sources of stars, exoplanets and even the moons and planets of our solar system.

The huge telescope, which has already cost more than $7 billion (£5 billion), is the successor to the orbiting Hubble Space Telescope.

The James Webb Telescope and most of its instruments have a temperature of about 40 K – about minus 387 degrees Fahrenheit (minus 233 degrees Celsius).

It is the largest and most powerful orbiting space telescope in the world, capable of looking back 100-200 million years after the Big Bang.

The orbiting infrared observatory is designed to be about 100 times more powerful than its predecessor, the Hubble Space Telescope.

NASA likes to think of James Webb as a successor to Hubble rather than a replacement, as the two will be working alongside each other for a while.

The Hubble Telescope was launched on April 24, 1990, via the space shuttle Discovery from the Kennedy Space Center in Florida.

It orbits the Earth at about 17,000 miles per hour (27,300 kilometers per hour) in low Earth orbit at an altitude of about 340 miles.
