How do the speeds at which most nearby galaxies are moving away from the earth compare to the speeds of distant galaxies that are moving away from earth?
Distant galaxies are moving away from Earth at faster speeds compared to nearby galaxies. This is due to the expansion of the universe, where galaxies farther away experience a greater redshift, indicating faster recession velocities. This relationship is described by Hubble's Law, which states that the recessional velocity of a galaxy is directly proportional to its distance from us.
What else can I help you with?
Pyroclastic flow would be most likely in what kind of eruption?
Pyroclastic flows are most likely to occur during explosive volcanic eruptions. These flows consist of hot ash, rock fragments, and gases moving swiftly down the volcano's slopes, posing a significant hazard to nearby communities.
What is the beneficial effects of volcanic eruption?
it is fertile the oil nearby
Where is the Best Place to be if you are in your Car During a Tornado?
A car is not a good place to be. If a tornado is coming leave the vehicle and go to a sturdy building with a basement or to a storm shelter. If you are in the open and the tornado is still distant try to drive perpendicular or diagonal to its path (depending on what the road allows) to get out of its way. If the tornado is drawing near abandon the vehicle and lie in a ditch or depression.
How does the distance between Earth and the sun compare to the distance between earth and nerby stars and galaxies?
The Earth-Sun distance is referred to by Astronomers as an "Astronomical Unit" - or AU for short.It is a very useful unit for comparing distances between Earth, planets and Stars.Since Earth to the Sun is 1 AU, Jupiter orbits at about 5 AU, Saturn at 10 AU, Uranus at 19.2 AU, and Neptune at 30 AU.The furthest we've ever sent a probe is Voyager 1, launched in 1976. It has only traveled 106 AU in all that time.By comparison, 1 Light Year (distance light travels in 1 year), is 63,276 AU. By interesting coincidence, this is very close to the ratio of 1 mile to 1 inch. If Earth were 1 inch from the Sun, a Light Year would be about a mile.The nearest Star to the Sun is Proxima Centauri, at 4.22 Light years, which is about 267,023 AU.Sirius is the the brightest star visible in the night sky, and is about 8.6 LY, or 544,171 AU from the Sun.The Milky Way Galaxy is about 75,000 Light Years across, which translates to 4.746 billion AU.Although there are several small galaxies within 250,000 LY of the Milky Way, the nearest Large Galaxy, M31 in Andromeda, is situated about 2.54 Million light years from here. In AU, that is about 162 billion AU.
How does a marshland prevent flooding in a nearby town?
Marshlands act as natural sponges by absorbing excess rainfall and slowing down the flow of water, thus reducing the risk of flooding in nearby towns. The marsh plants, like reeds and grasses, help to stabilize soil and reduce erosion, further aiding in flood prevention. Additionally, marshlands provide a natural buffer that can store excess water during heavy rainfall events, helping to regulate water levels and reduce the impact of flooding on surrounding areas.
In which direction are nearby all galaxies moving relative to earth?
Nearly all galaxies are moving away from our galaxie and planet.
How many galaxies are approaching milky way galaxy and how many are moving away related to the cosmological red shift?
Most galaxies are moving away from us. Only a few galaxies, which are nearby, are moving towards us.
Are distant galaxies moving away slower or faster than nearby galaxies?
Here is what i belive to be the correct awnser. If you belive in the big bang theory then you swould know the universe started from the middle and started expanding out so the closest galaxie is moving away with us but distant galaxies are also moving away from us now i dont know about how they move or what speed they move at or if theres a differnce it is possible considering some galaxies formed billions of years after our a slowley catching up with as so i belive it varies now i hope this answer your question people may edit this in future and make it easyer to understand.
Nearby galaxies may not show a redshift?
Nearby galaxies won't show much of a redshift, because they aren't moving away very quickly - or at all. For example, the Andromeda Galaxy, M31, is actually getting closer - and will collide with the Milky Way in about 3 billion years.
What did Hubble find out about the most distant galaxies?
Hubble Space Telescope observations revealed that the most distant galaxies are much younger and smaller than those found nearby, providing insights into the early universe. These galaxies often exhibit irregular shapes and higher rates of star formation, indicating they are in a formative stage of evolution. Hubble's findings also support the concept of galaxy formation and evolution over cosmic time, showing that galaxies have grown and evolved significantly since their inception. Additionally, the discovery of these distant galaxies has helped refine the understanding of the universe's expansion and the influence of dark energy.
Are any Galaxies moving away at half the speed of light or faster?
Yes. The farthest known galaxies move away from us faster than the speed of light. While this is not possible for nearby objects, in this case space itself is expanding.
What is a synonym for not nearby?
far, distant, long.
Why isn't the look-back time important among nearby galaxies?
Galaxies change very slowly.
What other galaxies do you have in unniverse?
For a start, look up "Local Group" in the Wikipedia. This will show you a list of nearby galaxies.
A nearby galaxy?
Horse Isle Answer: Andromeda~Callileeno on Chestnut ServerThe Canis Major Dwarf Galaxy is the closest galaxy to us but the Andromeda Galaxy is th largest spiral galaxy near us.Look on this site for more info...http://www.brighthub.com/science/space/articles/41000.aspx
Where can a hypernova be found?
A hypernova can typically be found in regions of space where massive stars are forming, particularly in galaxies with active star formation, such as spiral galaxies and starburst galaxies. These explosive events usually occur at the end of a massive star's life cycle, particularly in stars with more than 30 times the mass of the Sun. Hypernovae are often associated with gamma-ray bursts and can occur in both nearby and distant galaxies, revealing insights into the universe's evolution.
Which astronomer argued that the milky way is huge and other galaxies are merely small nearby companions?
Shapley is the astronomer that argued that the milky way is huge and other galaxies are merely small nearby companions.
