Why do scientists use telscopes?
Scientists use telescopes to observe and study objects in the sky, such as stars, planets, galaxies, and other celestial bodies. Telescopes allow scientists to gather important data, study the properties and behavior of these objects, and make new discoveries about the universe.
What did the hubble telescope find?
The Hubble Telescope has made many significant discoveries, including the age of the universe, the rate of its expansion, the existence of dark energy, and vast numbers of galaxies and stars. Additionally, it has captured stunning images of celestial objects like planets, nebulae, and galaxies.
How do scientists use spectrographs?
Scientists use spectrographs to analyze the light emitted or absorbed by an object. By spreading light into its various wavelengths, spectrographs can reveal the chemical composition, temperature, and motion of celestial objects such as stars, planets, and galaxies. Scientists study these spectra to gain insights into the properties and dynamics of the objects being observed.
What other things are in space?
In addition to planets, stars, and galaxies, space is also home to black holes, asteroids, comets, nebulae, and various celestial objects like pulsars and quasars. Space is vast and diverse, containing a wide range of phenomena and objects that continue to fascinate scientists and astronomers.
What are scientists called who study the Universe?
Scientists who study the Universe are called astronomers. They use telescopes and other instruments to observe and analyze celestial objects like stars, planets, galaxies, and black holes. Some astronomers also study the fundamental forces and laws that govern the Universe.
How do scientists discover planets in other galaxies?
They take some tacos and throw them in space and see if they hit another planet.

Are galaxies related to planets?
Galaxies are generally a collection of stars. But within any galaxy, there are lots of other objects, including planets. So galaxies are related to planets in some ways.
How many methods can scientists discover planets in other galaxies?
Scientists primarily discover planets in other galaxies through indirect methods, such as observing the dimming of light from a star when a planet passes in front of it (transit method) or analyzing the wobble of a star caused by an orbiting planet (radial velocity method). Direct imaging of exoplanets in other galaxies is more challenging due to the vast distances involved, but advancements in technology may make this possible in the future.
What invention helped early scientists discover more planets?
The invention of the telescope by Galileo Galilei in the early 1600s helped early scientists discover more planets. By using telescopes to observe the night sky, astronomers were able to see celestial objects more clearly and detect planets that were previously invisible to the naked eye.
In which system(s) are the distances between the objects the largest compared to the size of the objects?
In the solar system, the distances between planets are much larger compared to the size of the planets themselves. In the universe, the distances between galaxies are also vast compared to the sizes of the galaxies.

Are there plantes in other galaxies?
Probably, though most planets discovered so far - or perhaps all of them - are in our own galaxy. The reason for this is simply that it is easier to discover planets when they are relatively close to us. But, having discovered about a thousand planets nearby, there is no particular reason to believe that other galaxies would be devoid of galaxies. After all, the same laws of physics work in other galaxies as here.
What invention help scientist discover the planets have moons?
The Hubble telescope helped scientists to do this.
How many more planets did they discover?
Within our solar system, there are 8 planets, and 4 dwarf planets. There are also over 500 dwarf planets from 2 galaxies that have been discovered orbiting other stars.
What are some objects with a lot of mass?
Some examples of objects with a lot of mass include planets, stars, black holes, and large celestial bodies like galaxies.
How do scientists learn about galaxies?
they learn by going to a good school and study the stars and planets
