What else can I help you with?
Why do astronomers find it difficult to locate extrasolar planets with telephones?
Astronomers cannot locate extrasolar planets with telescopes because these planets are outside of our solar system and too far away for telescopes to directly observe. Instead, astronomers use indirect methods such as radial velocity and transit techniques to detect these distant planets.
Why would it be futile to attempt to detect sounds from other planets even given the very best audio detectors?
Sound waves cannot travel through the vacuum of space, so there would be no sounds to detect coming from other planets. We rely on instruments like telescopes and spectrographs to study celestial bodies instead.
Which planets have atmospheres so dense that one cannot see through them with a telescope?
The planets with atmospheres so dense that one cannot see through them with a telescope are Venus and Titan, the largest moon of Saturn. These thick atmospheres are composed of gases and haze that block visible light from passing through, making it impossible to see the surface using traditional telescopes.
Are radio telescopes detect objects that optical telescopes cannot?
Yes, that is correct.
Can you see other planets outside our solar system. Or are they all just stars. How about if you use a telescope?
You cannot see planets outside our solar system with the naked eye. And, only a rare few can be seen with the most powerful telescopes. Most are detected by way of indirect measurements -- by observing their effect on their suns (stars).
Why sun can not revolve around the planets?
The sun is much larger and more massive than the planets in our solar system, so it exerts a much stronger gravitational force. This gravitational force keeps the planets in orbit around the sun, rather than the other way around. Additionally, the sun is a star that generates its own energy through nuclear fusion, making it the central body around which the planets orbit.
What can planets do that dwarf planets cannot do?
Actually Dwarf planets are planets which are very small in size and cannot be called planets but not as small to be called asteroids, so the name dwarf planets.
How many exo-planets are there?
As of October 2021, astronomers have discovered over 4,500 confirmed exoplanets. This number continues to grow rapidly as new telescopes and technology are developed to detect more of these planets outside of our solar system.
How can you see Kuiper Belt from Earth?
The Kuiper Belt is a region beyond Neptune that consists of icy bodies and dwarf planets. You cannot see it visually from Earth without the aid of a telescope, as it is too faint and distant. Astronomers use powerful telescopes to study and observe objects within the Kuiper Belt.
How have telescopes changed since they were invented?
They have changed because now there is a telescope in space called the "Hubble". I can see things that regular telescopes on Earth cannot see.
What cannot be used to study the celestial bodies?
Earth-based telescopes typically cannot be used to study celestial bodies that emit high-energy electromagnetic radiation, such as gamma rays and X-rays. These types of radiation are absorbed by Earth's atmosphere, so specialized telescopes, like space telescopes, are needed to study them.
What is the difference between microscope and telescope?
telescopes cannot see tiny things or microorganisms
