Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have captured a direct image of HIP 65426b, an extrasolar gas giant about 6 to 12 times more massive than Jupiter.'
HIP 65426b is located approximately 363 light-years away in the constellation of Centaurus.
First discovered in 2017, the planet is 1.5 times larger than Jupiter and up to 12 times as massive.
It orbits the A2-type star HIP 65426 (also known as HD 116434), which is almost 3,000 K hotter and twice as massive as the Sun.
HIP 65426b orbits the parent star at a distance of 92 AU (astronomical units); it is sufficiently distant from the star that Webb can easily separate the planet from the star in the image.
“This is a transformative moment, not only for Webb but also for astronomy generally,” said Dr. Sasha Hinkley, an astronomer at the University of Exeter.
“I think what’s most exciting is that we’ve only just begun,” said Dr. Aarynn Carter, an astronomer at the University of California, Santa Cruz.
“There are many more images of exoplanets to come that will shape our overall understanding of their physics, chemistry, and formation.”
“We may even discover previously unknown planets, too.”
