How far is the constellation norma away from earth?
The constellation Norma is approximately 200 million light years away from Earth. It is a small and inconspicuous constellation that can be seen in the southern hemisphere.
What is the farthest galaxy ever observed by Hubble?
the farthest the hubble telescope can see is about 150 million light years away!
Why is an object 15 million light years away like looking at an object 15 million years ago?
Because you might have seen it in a telescope years ago idkAnother AnswerA light year is a measure of distance. If an object is 15 million light years away, the light you are looking at in this moment was produced 15 million years ago. If a star that far away went supernova at this moment, we wouldn't know it for another 15 million years.The light we see on the surface of our planet from the Sun is a little over 8 minutes old, because it took that light about 8 minutes to travel from the Sun to Earth.
Can see a supernova explosion on another galaxy?
Actually before the rise of visible light there is a surge in neutrinos that can give a warning of a super-nova by as much as five days. Then comes the light flash in all forms of electromagnetic radiation (including visible light).
Why is the light of a distant explosion seen first before the sound of the explosion is heard?
Simply because light travels faster than sound. The speed of light is 186,000 miles per second while the speed of sound is only about 1,126 feet per second. Therefore, you see the explosion before hearing the blast. It's the same when you experience a thunderstorm - you see the lightning, and the thunder follows after a few seconds - depending how close you are to it.
Will an explosion be seen or heard first?
Seen first before hearing as velocity of light very much higher than that of sound
How far away is the farthest object seen by a human?
The farthest object seen my mankind is a gama ray burster approximately 13 billion (thousand million) light-years away. Previously the next farthest object was 12.8 billion light years away. A light year is approximately 24 trillion miles. (12 zeros) or 36 trillion km. The object seen was about 312,000,000,000,000,000,000,000 miles away. More interestingly, it happened when the universe was only on to two Billion years old.
What is the distance of the stars you see at night?
If you mean, with the naked eye: anywhere between 4 light-years, and thousands of light-years; however, there are three galaxies you can see with the naked eye, two of which are about 180,000 light-years away, while the Andromeda Galaxy is 2-3 million light-years away. With powerful telescopes, on the other hand, stars and galaxies can be seen that are millions, and even billions, of light-years away.
How far away is the dwarf star from earth?
The nearest dwarf star is Proxima Centauri, about 4.24 light years away and so dim it can't be seen in binoculars.
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.
Grab nebula was first seen on earth in 1054 how long did it take to get here?
Supernova(SN) 1054 Crab Supernova was first seen in 1054, it is estimated to be 6,500 light years away, so 6,500 years
How far is the constellation norma away from earth?
The constellation Norma is approximately 200 million light years away from Earth. It is a small and inconspicuous constellation that can be seen in the southern hemisphere.
When do stars appear?
The light emited by stars can take thousands of years to reach the Earth, because the stars can be located thousands of light years away. Stars viewed from Earth can only be seen at night because the light from the sun creates a glear on the atmosphere.
Using the velocity of light devise a strategy for finding out when the supernova actually occurred relative to when the Chinese astronomers saw the explosion in 1054 Use the equation drt?
The distance to SN 1054 is about 6,300 light years. The date it was seen is 1054 x - y =z
Why is a rainbow only seen in the distance?
because the light travels through the water which splits the light and can only be seen from a certain distance away
How far away is a supernova?
Supernovas are massive stars that have exploded. It is not a name for a single star.Therefore their distances are varied.The Crab nebula (A former supernova) is located at a distance of about 6,500 light years.SN1987A (Seen in 1987) is about 168,000 light years from us. So the supernova occurred around the time of the emergence of homo sapiens.SN2006gy (Seen in 2006) is about 238 million light years from us. So it exploded around the time Vertebrates ruled the world!!Vela exploded approximately 11,000-12,300 years ago (and was about 800 light years away).
Is there any planets just like earth?
that remains to be seen. although the chances are slim, there might be an earth-like planet millions of light-years away!
