light & astronomy question?

Question

would you see a new star if you use a powerful telescope, but the light has not yet reached the Earth?

thanks for your help everyone, that has been a question I've been wondering about.

Answer 1

You answered the question yourself!!!

If the light had not yet reached the Earth, no one could see that light, no matter what power telescope they used.

Light we see from the Stars tonight has been traveling to us for hundreds, even thousands of years. I know that this idea is hard to grasp, but the Stars of other solar systems around ours are very, very far away from us.

The Milky Way Galaxy is a disk shaped galaxy roughly 100,000 light years wide and a few thousand light years deep. (Ian Ridpath, ASTRONOMY, DK Publishing, NY, NY.) Within the Milky Way there are some 1000 billion stars.

The Andromeda galaxy is the biggest galaxy in the local group of galaxies which are our neighbors, and it is twice the size of the Milky Way Galaxy. There are at least two dozen other galaxies in that same local group. Some galaxies are so dense with stars that their appearance is like that of a cloud.

As a result, the better your telescope is, the more stars you can see clearly. Pausing to look more closely, you can even see more stars beyond those that you see clearly. So, the universe is truly vast and magnificent to behold.

Answer 2

No.

The light travels at the same velocity regardless of how it is detected. Using a telescope does not "speed up" the light in any way. If the light from a star has not yet reached the earth, no telescope would be able to see it, since telescopes are simply light gathering optical devices.

Answer 3

surely, you can't. Because your telescope is located on the Earth, so the light of star has to reach the Earth before you can see it through your telescope

Answer 4

No, you would not.

Light travels very fast, but it obeys a definite speed limit. Until the light from a new star has time to reach the Earth, we will have absolutely no clue that it exists.

Even when something new happens on our Sun, like a solar flare, we don't know it for until about 8 1/2 minutes after if happens.

Answer 5

interior the army I used the two types whilst on look after accountability at Guardpost Collier and Guardpost Oulette interior the Korean DMZ interior the overdue 80's. The infrared shows adjustments in temperatures and it does not desire any mild. It shows heat bodies as a vibrant purple shape, and as issues cool off they provide the effect of being darker. something approximately 40 stages or decrease seems black. they're super for gazing for stay animals. I watched a fieldmouse at a pair of million,000 yards with the T.O.W. missile night sight it is IR. The starlight form of nightscope amplifies ambient mild. It labored basically nice interior the woods most of the time. In a depressing sufficient place, alongside with a closed room or a cave, they did not have sufficient mild to escalate. this type shows each thing in colors of green. they're stable for many issues, yet plant existence and fauna will take place extra suitable with the IR.

Answer 6

If the light hasn't got here then there would be nothing to see, would there?

Imagine if you saw a distant explosion, and listened through a powerful amplifier. You wouldn't hear anything until the sound arrived, would you?

Answer 7

Yes, with radio telescopes light is irrelevant. If you were to try to find a new star looking for the gamma burst would be your best bet. Because the wave speed is not based light speed constant one could detect it prior to the particles, or photons arriving.

Answer 8

no, to see something you have to have light from it reaching your eye, even if it comes through the hubble first.

Answer 9

The way that they are found most of the time is with photos.

Answer 10

the answer depends on the distance from you to the star. but probably not, taking into account the distance of the nearest star alph centuri
