How Do I Find Distance Using Redshift?

AI Thread Summary
To find distance using redshift in astronomy, start by understanding Hubble's Law, which relates the recessional velocity of an object to its distance from Earth. The formula involves calculating the recessional velocity by multiplying redshift by the speed of light. Once the velocity is determined, use Hubble's constant (Ho) to solve for distance with the equation: distance = velocity(recessional) / Ho. This method provides a straightforward approach for first-year astronomy students to calculate cosmic distances. Utilizing these resources can significantly aid in grasping the concept.

redshift ""first year astronomy""

how do i find distance using redshift? please keep in mind that this is first year astronomy course i am currently taking

having some trouble doing it. don't know where to start
 
Astronomy news on Phys.org


got it so..

redshift time speed of light = velocity(recessional)

velocity(recessional)= Ho times distance

so... solve for distance

thanks man helped me a lot!
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
