Back in 1995, one of Jupiter's exoplanets was discovered that was orbiting a main star in the said planet. Just recently, it has then been found that there were signs of an existence of water in the said exoplanet, named by the scientists as "51 Pegasi B."
Exoplanet Discovered Over 20 Years Ago Scientifically Known As "51 Pegasi B"
Although 51 Pegasi b was not the first exoplanet to have been discovered in Jupiter, it was one of the most distinguished due to its ability to orbit around a star. This star, widely known by scientists as a main sequence star is considered to be a conventional one much likely similar to the sun. The exoplanet 51 Pegasi b as a giant planet that was orbiting so close to its star it was almost impossible for astronomers to have been considered probable at the time. However, it was later on believed by astronomers that large planets may have been formed far from their stars but later on move closer over millions of years.
Today, more than two decades after the discovery of 51 Pegasi b, there has been more information gathered about the existing exoplanet. A group of American and Dutch astronomers have further studied 51 Pegasi b and discovered more of its atmospheric contents, orbital properties and even a greater knowledge on its natural mass. In addition to that, it has been reported that the team of astronomers studying the exoplanet has presented a 5.60 detection of water in the atmosphere of 51 Pegasi b. This information has then confirmed that the existing exoplanet is a double-lined spectroscopic binary.
Traces Of The Components Of Water Detected From The Said Exoplanet
In layman's terms, a spectroscopic binary system exists when the spectrometer used to measure changes in the frequency of a star's light picks up light from both of the stars, the exoplanet and the main star closely similar to the sun. The spectrometer then picked up the presence of water in the exoplanet. However, there are still further studies that need to be conducted in order to confirm the properties and chemicals present in the exoplanet.
