1965 Cosmic Times Articles

1965 Poster

This poster is the fourth issue of Cosmic Times pinned to the discovery of the cosmic microwave background (CMB). This new discovery settles the debate raised in the 1955 issue of the origin of the universe – it comes down firmly on the side of the Big Bang Theory.

Content Overview

The date for this poster was chosen to coincide with the discovery of the cosmic microwave background (CMB). The CMB is the remnant radiation from very early in the Universe, the discovery of which clearly made the Big Bang the lead theory on the origin of the Universe. The realm of astronomy has grown, with the addition of observations of X-rays from outside the solar system, and, indeed, outside of the galaxy. Astronomers have also just gotten their first glimpse of the invisible dark matter.

  • Murmur of a Bang
    • Summary:Two astronomers discover the remnant radiation from the Big Bang while trying to characterize the sources of noise in a radio antenna they wished to use for astronomical observations.

  • Big Hiss Missed by Others
    • Summary: The signature of the remnant radiation from the Big Bang could have been found by others, if they had known where to look, but Penzias and Wilson had just the right set of circumstances to make the discovery.

  • Cosmic X-ray sources Found Outside the Galaxy
    • Summary:Astronomers continue to look at the Universe in a different light, this time in the X-ray. This article discusses the discovery of two sources that shine in X-ray, both thought to lie beyond our Galaxy.

  • Quasars: Express Trains to the Netherworld
    • Summary: At the edge of the Universe, astronomers are finding objects called quasars, originally for the term quasi-stellar objects. The nature of quasars is unknown in 1965, but it is clear that they lie at large distances, and so must be very old.

  • Galaxies Still Misbehaving
    • Summary: Recent observations have made it clear that there is more matter contained in galaxies than astronomers can easily account for. This leads to the idea of dark matter.

Style Notes

The language in the 1965 newspaper mimics the style of writing that would have appeared in a real 1965 newspaper. The style is very close to modern-day newspapers, and should not be as difficult for your students as previous papers. However, the concepts may be a bit more difficult than in the previous Cosmic Times editions. As with other editions, we have provided three versions of the text in newletter form: an Early Edition aimed at 7-8 graders, a Home Edition aimed at 9-10 grades (with text from the online edition), and a Late Edition aimed at 11-12 grades (with the text from the poster). These, along with a glossary and questions for understanding are available above.

The poster also shows a layout that mimics the papers of the time, however, we have taken some creative license to make it more readable in a classroom setting.
