PKS 1127-145 Absorber
Illustration
On their way to Earth, the X-rays from PKS 1127-145
pass through a galaxy located about 4 billion light
years from Earth. Atoms of various elements in this
galaxy absorb some of the X-rays. By measuring the
amount of absorption, astronomers were able to estimate
that the intervening galaxy contained only about 20
percent as much oxygen as our Milky Way Galaxy has
now.
