How are the strange worlds of this world and other lands?
For thousands of years, people believed that the Earth was fixed at the center of the universe and that every other celestial body revolved around our planet. But over time it became clear that the earth did not occupy such a special position. People realized that maybe the earth is not as unique as they thought. Some even wondered if there might be planets around other stars. To date, astronomers have found more than 5,000 exoplanets. While astronomers initially expected to find systems similar to our planet, most of the first exoplanets they discovered were wild and strange compared to our own solar system. Hubble's exoplanet studies continue to expand our view of planetary systems by revealing even stranger orbs, often by probing their atmospheric chemistry through spectroscopy—the study of information encoded in light. Hubble's spectroscopic observations have revealed faded worlds shrinking into space as they lose their atmospheres, and planets in odd orbits. But the observatory has also revealed worlds that are more like ours.
How is the weather and star relationships?
Earth exhibits a wide range of weather, from rolling thunderstorms to sunny skies and blizzards. Thanks to Hubble, astronomers have learned about the weather some exoplanets experience, including molten iron showers, amber skies, and even sunscreen-like snow flurries. Future observations could reveal more about the factors that drive the climates of exoplanets, including their relationships with their host stars. If our own host star, the Sun, were just a little warmer or cooler, or if it were much older or younger, Earth might not be habitable. While Sun-like stars may be the most obvious targets for the search for habitable planets, these stars are not too hot, too cold, or too violent to host life-friendly planets over large stretches of cosmic time. Hubble's upcoming observations will help us focus our search for habitable worlds and bring us ever closer to the possibility of finding life on other planets. New stars in the Milky Way form from swirling clouds of gas and dust scattered throughout our galaxy. The remnants of those clouds remain and surround each star in a disk that becomes more diffuse as the debris clumps together to form objects like planets. Hubble's studies of exoplanets have focused mainly on the planets themselves, but sometimes surprises turn up in the disks in which these planets are embedded.
Dear James Garry
Hello, dear teacher
Because I am interested in astronomy, I pose my questions in such a way that I relate the relationship between the climate of the planet to the space around it and even interplanetary and solar activities. That's why I asked these questions. Thank you for your kindness and love. Abbas
