What does the Hubble telescope measure?
It studies everything from the formation of distant galaxies to the planets in the solar system. The camera can see three different kinds of light: near-ultraviolet, visible and near-infrared. But Hubble can only see each kind of light one at a time. Human eyes can see visible light.
What gives Hubble its excellent clarity its size or its position in space?
In space, the clarity of Hubble’s images (defined by angular resolution) is limited by the size of its 2.4 metre mirror rather than atmospheric turbulence. Being in space gives Hubble incredible advantages compared to Earth-bound telescopes.
Why is Hubble so good?
Hubble has helped scientists learn about our solar system. The telescope observes comets and planets. Hubble even discovered moons around Pluto that had not been seen before. The telescope has helped scientists understand how planets and galaxies form.
Which is bigger galaxy or universe?
Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!
What is the largest known star?
UY Scuti
What if our sun was a blue giant?
A blue sun wouldn’t change that. It would have a number of side affects though. Since blue stars burn hotter then red and yellow stars the Earth would be much hotter to the point that there would be no atmosphere and thus nothing to scatter any light. The sky would be black except for the very intense sun up there.
What is the largest star in our galaxy?
Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.
