The JMST Telescope (JWST) has achieved another landmark, with a direct picture of a very far planet in a solar system, unlike our astronomers on Tuesday (June 10).
the Exoplanet -14 Herculis C, or 14 her C for a short time-a sun-like star about 60 light-years away from Earth in the constellation of Hercules. In the new Jwst The image, appears as a mysterious, orange point, and its color as a result of the heat that radiates from its translated atmosphere to visual degrees.
Astronomers estimate that 14 C formed about 4 billion years ago and has a temperature in the cold atmosphere of 26 ° F (minus 3 degrees Celsius).
14 It revolves around its star about 1.4 billion miles (2.2 billion km), or about 15 times from its Earth’s star Sun. If you are placed in our solar system, it will sit between Saturn And Uranus.
This image was taken of the EXoplanet 14 Herculis C tool by the NIRCAM tool (the camera near the infrared) on the James Web telescope from NASA.

However, unlike the orbits of flat planets, Our solar systemHerculis 14 system is significantly not specified. Its well -known planets, including 14 C, their orbit, with angles of about 40 degrees to each other, creating a “X” crossing pattern around their star.
Palmer said that this unusual design may be the cause of the early directing of a third planet from the regime, as the remaining two threw the “pocket war tightening” disturbed in terms of gravity.
“It seems that this oscillation is stable during long time standards,” he said. “We are trying to understand the types of prose the planet that can produce such a strange composition of orbits.”
This instability turned into a scientific advantage for the Palmer team. Of the about 6000 of the well -known external planets, only a small part was photographed.
“Do this very difficult,” Palmer said. He said that the planets shine thousands – and in some cases, even millions or billions – from the times that beats from the stars in which they revolve, so “they resemble the brightness next to the beacons.”
Most of the external planets that were filmed directly are young gas giants that emit enough of them Stars. On the contrary, cold planets and the elderly like 14 C usually have very dim.
Palmer said that the diagonal orbit of the oblique planet, outside the ketter is great news for direct photography. “
Using a stars blocking of a telescope known as a CoronagraphPalmer and his team succeeded in isolating the planet’s infrared glow.
Palmer said in a statement.
According to 14 years of age, it is about 4 billion years old, its bloc, which is about seven times JupiterAnd computer models of how the planets develop, researchers expected the planet to appear brighter – or emit more heat – than already happens in the JWST image.
Palmer said: “The planet is actually fainting greatly from what we expected,” Palmer said. “We don’t think this is a problem with evolutionary models.”

Palmer said that through an investigation into the atmosphere in the world, JWST discovered carbon dioxide and carbon monoxide at temperatures where methane was usually expected, indicating that strong garbage lifting operations carry hot gases from the depths of the atmosphere to the cold upper layers. These gases, perhaps along with thin ice clouds, reduce the heat that escapes into space, making the planet look cooler and more slight than expected.
With 14 C, astronomers expand the external planets that can study. By examining planets with various masses, temperatures and orbital history, scientists hope to have a deeper understanding of how the systems of planets, including our shape and development.
“We want to understand how these planets change, because we want to understand how we got here,” Palmer said.
