James Webb telescope captures the first direct images of an exoplanet | James Webb space telescope
the James Web telescope for space He took direct images of an unprecedented planet outside our solar system at the first discovery abroad.
Notes reveal the presence of a planet, called Twa 7 B, which makes its way through a disk of glowing dust and rock debris in the orbit around the 110 -meter light star of the Earth. Around the Saturn mass, the planet is ten times less large than any planet outside the previous planets to be observed directly with a telescope and provides new visions in a planetary system in its infancy.
“Here we look at a system of about 6 meters old, so we are really witnessing the youth of the planetary system,” said Dr. Ann Marie Ligrang, an astronomical physicist at the Paris Observatory who led the notes.
Since the discovery of the first external planets in 1992, nearly 6000 others have been discovered, but almost all of these things have been identified through indirect methods such as discovering the shadow of the planet that passes through the host of the host star.
Immediately, external planet photography is a great challenge because they are less bright than the host star, and as shown from Earth, it is located near their star. To overcome this, Lagrange and its colleagues developed a telescope designed to reproduce the eclipse effect, hiding the star to facilitate the monitoring of the surrounding things that may drown.
This allowed them to monitor the “TWA7” star “pole” – and it is effective on the planet’s disk from the top. The photos reveal three concentrated episodes of the center of dust and debris around the star – the structures that were previously attributed to the invisible “sponsor” planets that descend through the disk. In this case, astronomers were able to make notes to a planet, which appears as a brighter source inside a narrow ring.
The planet is believed to be a giant gas, around the Saturn mass, which makes it the smallest group planet to be observed by direct images. In a position about 50 times away from its star like the Earth of the sun, Twa 7 B has a tropical period of several hundred years.
The result was reported in the magazine nature.
