which statement about exoplanets is true?
They only appear once before they dissapper in space
They are discoved when they dis a star they pass by
They are odjects that are no longer considered planets
They can be detected by ordinary telescopes
The statement "They can be detected by ordinary telescopes" is true. Exoplanets are planets that exist outside our solar system. While some exoplanets have been discovered through various methods, including transit observations (where they pass in front of their host star), gravitational microlensing, and radial velocity measurements, others have been directly imaged using advanced telescopes. Ordinary telescopes can be used to observe and detect exoplanets in certain cases.
which main problem is being solved by the hubble space telescope
The main problem being solved by the Hubble Space Telescope is the ability to observe the universe from outside Earth's atmosphere. By being located in space, above the distortion caused by Earth's atmosphere, Hubble provides clear and detailed images of celestial objects. It has greatly contributed to various fields of astronomy, including determining the age of the universe, studying distant galaxies, identifying exoplanets, and observing many other astronomical phenomena.
