Astronomers have found many exoplanets in the vast space, but none of them has been directly imaged. They usually confirm the existence of exoplanets by indirectly observing the influence of planets on their host stars. Astronomers recently shared for the first time images of an exoplanet discovered by direct means, beta Pictoris c. The young exoplanet was discovered by the very large telescope and NACO instruments in 2008, and then the astronomical observation team continued to track the exoplanet with the high contrast instrument (sphere). This method is called direct imaging, which can find the extrasolar planet by directly taking pictures of the stars. < / P > < p > can tell its young age because it and its exoplanets are still surrounded by a large amount of dust debris. On a cosmic scale, the two exoplanets orbiting the star are infants, about 18.5 million years old. Beta Pictoris C, the second of the two planets, was originally discovered using radial velocity. < / P > < p > beta Pictoris C is a gas giant with a mass of 13 times that of Jupiter. The researchers point out that there are very few exoplanets that can be imaged directly using existing technologies, and one challenge for imaging distant planets is that they must be far enough away from the stars to avoid disappearing into the bright light. The researchers also said it would help if exoplanets were young and warm enough to produce thermal radiation. < / P > < p > the direct image of beta Pictoris C reveals an interesting thing, which is that it is surprisingly weak. Although the two planets are similar in size, they are six times dimmer than their siblings, and the degree of dimming suggests that it is much colder than its brother star. Global Tech
