An explosion that occurs 100 light years away can be seen on Earth because light travels at a finite speed, so it takes time for the light from the explosion to reach us. Since the speed of light is finite, any event that occurs in the universe will have a delay in when we see it on Earth, depending on its distance.

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.


Explosion takes place on the moon will it be seen?

An explosion on the moon would not be visible from Earth without specialized equipment like powerful telescopes. The moon is over 380,000 km away from Earth, so the explosion would be too small and distant to be seen with the naked eye.


What is the farthest galaxy ever observed by Hubble?

The farthest galaxy ever observed by the Hubble Space Telescope is GN-z11, located about 13.4 billion light-years away. This means we are seeing the galaxy as it was just 400 million years after the Big Bang.


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.

Grab nebula was first seen on earth in 1054 how long did it take to get here?

The Crab Nebula is about 6,500 light-years away from Earth. Since one light-year is the distance light travels in one year, it took 6,500 years for the light from the Crab Nebula's explosion in 1054 to reach Earth.


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.

Will an explosion be seen or heard first?

In most cases, the sound of an explosion will be heard before it is seen. This is because sound waves travel slower than light waves, so the sound reaches a person's ear before the light reaches their eyes.


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 can you see a nuclear explosion and what factors determine the visibility of such an event?

The visibility of a nuclear explosion depends on various factors such as the size of the explosion, weather conditions, and the observer's distance from the blast. Generally, a nuclear explosion can be seen from tens to hundreds of miles away, depending on these factors.


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.


How far could the cloud from the atom bomb been seen from?

The cloud from an atomic bomb explosion can typically be seen from dozens to hundreds of miles away, depending on the size of the explosion and atmospheric conditions. The cloud can linger in the sky for hours or even days, spreading further due to wind patterns.


A star's absolute magnitude is its apparent brightness as seen from?

A star's absolute magnitude is its brightness as seen from a standard distance of 32.6 light-years away. It accounts for the intrinsic brightness of the star without regard to its distance from Earth.


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).
