How do planets and planetary systems arise? An astonishing image from space can now illuminate the dark. It is the smallest exoplanet ever photographed.
Texas – These are special images from space: The images taken from the ESO’s Very Large Telescope and the Hubble Space Telescope show the latest giant planets outside our solar system – discovered and photographed by humans. It is about the exoplanet PDS 70b, which is orbiting the star PDS70 and appears to be still growing. The records are absolutely amazing because they can provide information about how the giant planet Jupiter formed, for example, billions of years ago in our solar system.
We don’t know much about the formation of giant planets. We now have the opportunity for the first time to witness how matter is transformed into a planet. Our results open a new research approach, “NASA quoted Brendan Bower from the University of Texas as saying.
Pictures from space – A young planet can provide information on planet formation
However, the discovery of the PDS 70b planet dates back to the 1990s. At the time, the image of the dwarf star 370 light-years from Earth was met with special interest from NASA and the European Space Agency. Scientists also discovered a protoplanetary disk through the image. What appears very mysterious is the appearance of a disk of gas and dust around a star. How exactly a planetary system could form out of this is one of the mysteries of our universe and has yet to be fully clarified.
In 2018, the PDS 70b planet was discovered near the star. This tiny giant planet, which is mainly made of gas, is said to have a mass several times greater than that of Jupiter. The researchers were able to deduce this from the recordings. The Max Planck Institute in Heidelberg announced that the PDS 70b is 22 times farther from its star from Earth than from the sun. In addition, the PDS 70b took 227.5 years to orbit its star, NASA said.

“This system is very exciting because we can be the material of creating a planet. It’s the smallest planet that Hubble has ever directly photographed. At the young age of five million years, the planet was still gathering matter and forming mass,” says Yifan Zhou of the University of Texas.
The new “Hubble” images enabled astrophysicists to find new details inside to see how the planet was formed. Radiation can be analyzed using the recordings. These estimates allow for how much matter is in the vicinity of the star or exoplanets. From this, in turn, it can be inferred how much an exoplanet has grown or whether moons have formed. “The Hubble records allow us to estimate the speed at which the planet is gaining mass,” says Chu.
The most recent reviews of these recordings were published by the research team in the April issue of The Astronomical Review. Another planet, called PDS 70c, was also discovered in the wonderful planetary system in 2019. NASA could have two extrasolar planets and the planetary system. Animation re-creation. Although around 4,000 exoplanets have already been recorded, only 15 can be imaged with a telescope. Recently, a NASA image of an exoplanet indicated a second atmosphere. *fr.de is a demo of IPPEN.MEDIA. (Delia Fries)
