One of the most important developments for humans in terms of space observation is the James Webb Space Telescope! The scientific community has great hopes because it will be much more capable than any other space telescope ever deployed by humans! They will be able to investigate very far-off space objects, something they have never been able to do. Proxima b is one of the things the JWST will observe to determine if the planet is emitting artificial light. Yes, what you heard is true! If aliens are responsible for the lights coming from Proxima b, scientists want to know! How does the JWST's concentration on the exoplanet influence you and what will it see?
Join us as we explore the Proxima b discovery by James Webb that changes everything! Let's jump into the video without wasting any time.
The universe is filled with exoplanets, which hold a lot of secrets. Any planets outside of our solar system fall under this category. Rogue planets are free-floating exoplanets that orbit the galactic center without being bound to any star, unlike the majority of them which orbit other stars. Exoplanets are numerous, but the majority that have been found so far are concentrated in the Milky Way, a very tiny area of our galaxy. Actually, the galaxy contains more planets than stars. Scientists can see compositions ranging from very rocky, like the Earth and Venus, to very gas-rich, like Jupiter and Saturn, by measuring the diameters and masses of exoplanets. Exoplanets are composed of the same elements as the planets in our solar system.
It is possible to have planets that are dominated by iron or carbon on some and by water or ice on others. The density of Styrofoam, fluffy planets, lava worlds with molten seas, and dense cores of planets still orbiting their stars have all been discovered by astronomers. Since the initial exoplanets were found in the 1990s, hundreds have been located using various detection techniques. However, it is quite uncommon for astronomers to observe an exoplanet through their telescopes in the same way that you might observe Saturn from Earth. Only a small number of exoplanets have been discovered by this method, and those that have tended to be young gas giant planets orbiting very far from their stars are known as direct imaging exoplanets.
