This is one of those things that when astronomers first saw them they went "oh fuck we've found extraterrestrial life".
Some examples:
As described at Section "Radio astronomy", this new type of telescope led to the exciting discovery of new types of astronomical objects, notably pulsars and quasars.
Ciro Santilli defines a "model protein" as a protein which has been significantly used in the history of protein science, in analogy to the term model organism.
Key characteristics of model proteins include:
- they are easy to obtain and are stable
- they are important to medical applications
- they are small and easier to understand for early studies
Important model proteins include:
- insulin: as a peptide hormone, this was small. Also it was useful and widely available even at pharmacies, The Eighth Day of Creation says you could get it a Boots, a major British pharmacy chain, and as such was a natural choice for the first sequencing by Frederick Sanger published in 1951
- hemoglobin
- keratin
Radio astronomy is cool because it revealed:The 1974 Nobel Prize in Physics was awarded for pioneering radio astronomy from the late 40s onwards done at the University of Cambridge which was an epicenter of early research in that area, leading to the creation of the Mullard Radio Astronomy Observatory in 1958.
- some very interesting new types of astronomical objects that were not as noticeable in the visible spectrum notably:
- quasars: quasars are extremely redshifted, which means by Hubble's law that they are very far from Earth, so the fact that we could see them at all meant they must have produced immense amounts of light
- pulsars: scientists thought they had found extraterrestrial life when they saw these regularly pulsating signal sources!
- cosmic microwave background which is a major evidence for the Big Bang
- radio wavelengths penetrate Earth's atmosphere better than the visible spectrum making it easier to make ground-based observations
