WebRedshifts: The Key to Quasars The answer came when astronomers obtained visible-light spectra of two of those faint “blue stars” that were strong sources of radio waves ( Figure 27.2 ). Spectra of these radio “stars” only deepened the mystery: they had emission lines, but astronomers at first could not identify them with any known substance. Web14. jan 2024 · Redshift helps astronomers compare the distances of faraway objects. In 2011, scientists announced they had seen the farthest object ever seen — a gamma-ray burst called GRB 090429B, which...

Web30. mar 2024 · The newly detected star is so far away that its light has taken 12.9 billion years to reach Earth, appearing to us as it did when the universe was only 7 percent of its current age, at redshift 6.2. The smallest objects previously seen at such a great distance are clusters of stars, embedded inside early galaxies. Web14. apr 2024 · From the difference in wavelength between the lab and the astronomical observation it's easy to calculate the redshift. So for this ALMA galaxy z = (1160–88)/88 = 12.2, this means the galaxy has ... Web18. feb 2024 · The puzzle was solved by the Dutch American astronomer Maarten Schmidt, who in 1963 recognized that the pattern of emission lines in 3C 273, the brightest known quasar, could be understood as coming from hydrogen atom s that had a redshift (i.e., had their emission lines shifted toward longer, redder wavelengths by the expansion of the … felugró ablakok letiltása edge
