What else can I help you with?
Can quasars be seen with the naked eye?
No, quasars are extremely distant and bright objects that cannot be seen with the naked eye from Earth. They typically require powerful telescopes to be observed.
Are quasars closest to earth?
No, quasars are not the closest objects to Earth. Quasars are extremely bright and distant celestial objects located billions of light-years away, typically at the centers of galaxies. The closest stars to Earth are in our own Milky Way galaxy.
How many quasars are in a galaxy?
Typically, a galaxy may contain one or a few quasars. Quasars are incredibly luminous objects powered by supermassive black holes at the centers of galaxies. They are rare and only occur under specific conditions, so it is not common for a galaxy to have multiple quasars.
Can you see quasars down on earth?
Yes, quasars are observed from Earth using telescopes and other astronomical instruments. They appear as distant, extremely bright objects located billions of light-years away at the center of young galaxies.
How are astronomers able to determine that quasars are so small?
Astronomers determine the size of quasars by analyzing the variability of their light. Quasars show rapid and dramatic changes in brightness over short periods, indicating that they must be very compact, likely smaller than our own solar system. By studying the time scales of these changes, astronomers can estimate the size of quasars.
Are quasars shiny?
They are bright maybe shiny.
Describe two key aspects of quasars?
Bright, distant, powerful, energetic, at the center of the galaxy.
Can quasars be seen with the naked eye?
No, quasars are extremely distant and bright objects that cannot be seen with the naked eye from Earth. They typically require powerful telescopes to be observed.
Are quasars closest to earth?
No, quasars are not the closest objects to Earth. Quasars are extremely bright and distant celestial objects located billions of light-years away, typically at the centers of galaxies. The closest stars to Earth are in our own Milky Way galaxy.
How far are quasars away from us?
Quasars can be very, very, very far away. And they are extremely bright. We've seen quasars that are 12 billion light years away from Earth (a light year is how far light travels in one year, and light travels at about 128 billion kilometers a second). Most quasars are actually big, bright galaxies shining from millions, or even billions of light years away from here.
This kind of bright energy source is about the size of the solar system and is billions of light- years from earth?
Quasars
Why are spiral galaxies so bright?
The brightness of normal galaxies is mainly due to stars; quasars are believed to get most of their energy output from the black hole at their center.
How many quasars are in a galaxy?
Typically, a galaxy may contain one or a few quasars. Quasars are incredibly luminous objects powered by supermassive black holes at the centers of galaxies. They are rare and only occur under specific conditions, so it is not common for a galaxy to have multiple quasars.
What is a very bright object believed to be an active center of a very young galaxy?
That probably refers to a quasar. Quasars are related to gigantic black holes.
Can you see quasars down on earth?
Yes, quasars are observed from Earth using telescopes and other astronomical instruments. They appear as distant, extremely bright objects located billions of light-years away at the center of young galaxies.
Are distant objects in space called quarks or quasars?
quasars
Describe how quasars got their name?
quasistellar object Technically, I shall tell you a better answer than the other one!At the very edge of the visible Universe scientists can see extremely bright and powerful objects called quasars. Quasars are about the size of our Solar System and produce more light and energy than 1000 galaxies. Think how incredible that is. A small object, not any bigger than our Solar System making so much power and light that it shines brighter than 1000 galaxies. Why are there no quasars near the Earth? The most distant objects visible in the Universe When we look at quasars which are 10-15 billion light years away, we are looking 10-15 billion years into the past. The quasars near Earth have died down long ago. What could produce so much Power and light? Quasars are probably super giant black holes, which are devouring entire stars. These black holes lie at the center of galaxies, and glow brightly as matter funnels into them.
