... Before the modern era of technological astronomy, to know anything about the Universe beyond our planet we relied on light. ... Historically the two rival ideas were that light was either a stream of tiny bullet-like particles or a wave wobbling its way through space. ... The light we see (visible light which is not the tautology it sounds) is only part of the electromagnetic spectrum, a great sweep of radiations which also includes radio, infra-red, ultra-violet, x-rays and gamma rays. ...

A jet from a distant black hole, called B3 0727+409, has been found using the Chandra X-ray Observatory. The light from this jet was emitted just 2.7 billion light-years after the Big Bang when the universe was only one fifth its current age. Jets in the early universe such as this one give astronomers a way to probe the growth of black holes at an early epoch. Typically, such distant jets are discovered in radio waves first, but not B3 0727+409 that was first found by Chandra. ...

... Journal: 1973, Astron Zh., ... The isotopic shifts of helium spectral lines have been measured for four high velocity OB-stars and one standard star. The spectrograms were secured at 2.6 m reflector of the Grimean observatory, dispersion beging 8 / mm . All five stars did not show the systematic isotopic shifts. But three lines of 53 Ari have shown shifts which are in agreement with theoretical ones, but other helium lines did not show such shifts. ...
