Planets extrasolar (exoplanet)
Discovery
An extrasolar planet is one that is outside our solar system, and astronomers believe in their existence for a very long time.
it's true - really visible until adequate tools available, in 1995 when Swiss astronomers Michel Mayor and Didier Queloz discovered a planet in the constellation Pegasus they called 51 Pegasi b.
How Important it is?
Not only that major Queloz and finally prove that extrasolar planets out there, but the methods they have used repeatedly to find more planets.
Nearly 500 extrasolar planets now known to exist, and it is only the beginning (now astronomers could only see the points of). Perhaps over time as more planets are discovered, one day we will find alien planet inhabited by a generous and sexy
Background Cosmic Radiation of Short Wave
Discovery
It was the discovery of a pair of radio astronomers, Arno Penzias and Robert Wilson, who discovered the radiation of cosmic microwave background in 1964.
CMBR is a type of radiation that is present in very small quantities (hence the term background) throughout space, and believed to be a remnant from when the universe is in the very early stages of birth.
How This Important?
CMBR offer evidence to support the Big Bang theory.
The idea is that this radiation has been present since the Big Bang, and has spread out since the universe expands (see number four in the list).
Its discovery was Enough to turn the idea of the Big Bang from a contested concept into the predominant explanation of our Origins.
Its discovery was enough to change the Big Bang idea from concept to concept undoubtedly the most plausible explanation of the origin of the universe. Penzias and Wilson won the Nobel Prize for their work;
