New York, Sep 2 (IANS) For the primary time, astronomers have used NASA’s James Webb Space Telescope to take a direct picture of a planet exterior our photo voltaic system.

The exoplanet referred to as ‘HIP 65426 b’ is a fuel large, which means it has no rocky floor and couldn’t be liveable.

The exoplanet is about six to 12 occasions the mass of Jupiter, and these observations may assist slender that down even additional.

It is younger, about 15 to twenty million years previous, in comparison with our 4.5-billion-year-old Earth.

“This is a transformative second, not just for Webb but additionally for astronomy usually,” mentioned Sasha Hinkley, Associate Professor of Physics and Astronomy on the University of Exeter within the UK.

The picture, as seen by means of 4 completely different gentle filters, exhibits how Webb’s highly effective infrared gaze can simply seize worlds past our photo voltaic system, pointing the way in which to future observations that may reveal extra data than ever earlier than about exoplanets, the house company mentioned in an announcement.

This picture exhibits the exoplanet ‘HIP 65426 b’ in several bands of infrared gentle.

A set of masks inside every instrument, referred to as a coronagraph, blocks out the host star’s gentle in order that the planet might be seen.

Astronomers found the planet in 2017 utilizing the SPHERE instrument on the European Southern Observatory’s Very Large Telescope in Chile and took pictures of it utilizing quick infrared wavelengths of sunshine.

Webb’s view, at longer infrared wavelengths, reveals new particulars that ground-based telescopes wouldn’t have the ability to detect due to the intrinsic infrared glow of Earth’s environment.

Since ‘HIP 65426 b’ is about 100 occasions farther from its host star than Earth is from the Sun, it’s sufficiently distant from the star that Webb can simply separate the planet from the star within the picture.

“It was actually spectacular how effectively the Webb coronagraphs labored to suppress the sunshine of the host star,” Hinkley mentioned.

Taking direct pictures of exoplanets is difficult as a result of stars are a lot brighter than planets.

The ‘HIP 65426 b’ planet is greater than 10,000 occasions fainter than its host star within the near-infrared, and some thousand occasions fainter within the mid-infrared.

“Obtaining this picture felt like digging for house treasure,” mentioned Aarynn Carter, a postdoctoral researcher on the University of California, Santa Cruz.

In July, James Webb Space Telescope produced the deepest and sharpest infrared picture of the distant universe to this point.
