Who discovered red shift in the starlight from distant galaxies?
Vesto Slipher and Edwin Hubble were the first who discovered a red shift in nearby Galaxies and as telescopes improved the formula could be applied to more distant Galaxies. The instrument that determines red or blue shifts is called a Spectroscopy. Ans. 2 The person who discovered (and explained) red-shift in the light from other galaxies was Vesto Slipher. Edwin Hubble, using Slipher's observations, realised that the amount of red-shift was proportional to the distance of the galaxy being observed. He formalised this as "Hubble's Law". This was what led cosmologists to the conclusion that the Universe is expanding. (see * below) The instrument that shows a spectrum is a spectroscope; that which measures it is a spectrometer and that which records it is a spectrograph. The instrument that measures red-shift of a distant galaxy can be anything from a travelling microscope to a ruler, depending on the quality of the photographs. Spectroscopy is the name of a set of processes, like photography or cookery , not any particular instrument. * The larger stars/galaxies are visible from further away. The larger stars/galaxies have a larger red shift without regard to their distance from us. (re: larger means more gravity means more red shift)
Where are nebulae located in spiral galaxies?
Nebulas could be located in any galaxy.
What led to the discovery of the distant pulling planets?
i think it could be tilt
Which instrument could be used to make distant objects seem larger and nearer?
Telescope
Can you see your own galaxy in the night sky?
No you would see an entirely different vista. Most of the stars you can see from earth would not be visible to the naked eye from the galactic core, and they would also be lost in a blaze of glory of the core suns. From within a planetary atmosphere you probably would not be able to see stars even at night, due to the ambient light. The core suns are packed about a quarter of a light year apart.
Could the expansion tank cause the car to overheat?
Yes it could
Why do astronomers think that quasars represent an early stage of galactic evolution?
There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.
What are some ways expansion and contraction could cause safety hazards?
If memory serves me, expansion and contraction can cause stress cracks in many materials, due to breakdown of molecules in the material.
What are distant galaxies with black holes in their centers called?
There have been some suggestions that the objects called quasars might be extremely active galaxies with unusually supermassive black holes at their centers at such great distance from us that it is not possible for telescopes to resolve their galactic structure, making them just look like very bright stars (quasi-stellar objects). However this has not been verified.If these suggestions are correct, these extremely active galaxies must be so distant that the light we are seeing from them must have been emitted only a short time after the big bang began, in the initial cycle of star formation, which would make them the earliest galaxies formed and likely very young galaxies. However if they are this young these extremely active galaxies might have galactic structures so different from the galaxies we are familiar with that even if our telescopes could resolve them, we might not recognize them as galaxies.
Could expansion when a substance is heated or contraction when a substance is coooled cause problems?
Yes, the thermal expansion is very important in physics and technology.
What did Edwin Powell discover?
The most important thing that Hubble discovered was that our universe is expanding. He could see this because he noticed that galaxies were moving apart (which he figured out by their red shifting). In fact, the expansion of our universe is speeding up and galaxies are moving apart faster and faster.
Proved that there were many galaxies?
Hubble.Edwin Hubble collected large amounts of data compiled from spectra of celestial objects,and correlated those with other data that could be interpreted as indicating the objects'distance from us.The pattern that emerged can be interpreted to imply that-- There are galaxies of stars that are distant from the galaxy in which we're located.-- All of the distant galaxies, in every direction from us, are moving away from us.-- The farther from us a distant galaxy already is, the faster it's moving away.Hubble proved none of this. But that should not be held against him or his welldeserved reputation as a brilliant scientist, because none of these things evercan be proven.In terms of a popular phrase that I love to tweak whenever I can, each of thesestatements is "just a theory".
What would cause no spark in a 1990 new yorker?
could be a bad coil but a distant second is a badly cracked distributor cap.
Are far and distant synonyms?
They can be. Something that is far away is distant. but in "How far did you come", you could not substitute distant.
Which objects began to form in your universe earlier stars or galaxies?
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
In the not so distant future?
There are many things that could happen in the not so distant future. You could have a death in the family for example.
What do galaxies think?
Milky way - "I bet i could take you on in a fight, Andromeda!" Andromeda - "Bring it on!" No galaxies do not think!
