The Incredible image shows a pair of exoplanets around a sun-like star

This is the first of its kind The image reveals a star system just 300 light years from Earth. this Was captured by the Very Large Telescope (VLT), which is managed by the European Southern Observatory and is located in the Atacama Desert of Chile. This is The first direct image of many exoplanets in orbit around a star similar to its own is considered, accordingly For an ESO press release.

“Even though astronomers have indirectly detected thousands of planets in our galaxy, only a small fraction of these exoplanets have been directly copied,” said astronomer Matthew Kenworthy of the University of Leyden, co-new -Author The paper, Published in The Astrophysical Journal Letters, in a press release describing this planetary system.

Star TYC 8998-760-1 is with two huge exoplanets.

Spectro-polarimetric high-contrast exoplanet research Instruments on VLT (SPHERE) made this image possible. Like the hand blocking the Sun, SPHERE used a tool called a coronagraph to remove unwanted light from the host star, allowing astronomers to see Nearby object.

This planetary system is quite young. At the age of 17 million, the host star, called TYC 8998-760-1, is just a child compared to our middle-aged Sun, which is 4.4byears lion year.

Another distinctive feature of this system Is that Exoplanet, both of which are largely gas giants, are significantly farther from their host star than our gas giants, Jupiter and Saturn. FaEther exoplanet is 320 AU (A unit of measurement with a distance from 1 AU S to EarthUnited Nations) From your star, While the other is in 160 AU. By comparison, Jupiter and Saturn are 5 and 10 AU from the Sun respectively.

YesSince giants are too big for giants. The inner exoplanet is 14 times the mass of Jupiter, while the outer object is six. Time of Jupiter’s mass.

Looking ahead, astronomers want to study these planets further and determine how and where they are Originally formed. A major question in astronomy is whether large planets such as these form close to their host stars and move rapidly outward Or if some other planetary migration scenario exists. The system is young and relatively close, making it an ideal candidate for such investigations.
