Astronomers directly observed exoplanet HIP 99770 b. This has been reported by the Japanese National Institute of Natural Sciences.
The vast majority of exoplanet discoveries have been made indirectly. Oftentimes, astronomers record minor dimming of the star as it passes over the planetary disk, or detect minor shifts of the star as the planet orbits—because it’s not really the planet orbiting the star. but both revolve around a common center of mass. Direct observations are very rare, only the most powerful telescopes are suitable, whereas the planet needs to be large and rotate very far from the dim star so that it does not blind the lens.
Initially, signs of the presence of an exoplanet in the HIP 99770 system were detected using the Gaia space telescope. Later, behind this system, 133 St. He made observations with the Subaru optical telescope, which was able to obtain direct images during his years. HIP 99770 b is 14 to 16 times the mass of Jupiter and orbits its star slightly more than 3 times the distance Jupiter is from the Sun. The planet, which is 10 times hotter than Jupiter, contains water and carbon monoxide in its atmosphere.
Astronomers hope to obtain direct images of Earth-like planets in the next decade with 30-metre telescopes under construction in Hawaii and Chile.
