Science In The 1990s And 2000s

America has seen some pretty awesome things, and as the country learned and retained information it would only turn and use the info towards the future. This is what is seen within the 1990s and 2000s. The discoveries or findings of the past are either used to drive experiments or expanded upon with new discoveries. Physics has previously seen lots of attention in particles such as quarks and neutrinos, biology is starting to build in genes and DNA. Astronomy has expanded in finding new information and will continue to do so. Throughout the 1990s and 2000s, physics, biology, and astronomy will expand on previous knowledge and use that to perform new things.
Many discoveries took place allowing scientists to have a better understanding in particles …show more content…

The 1990s saw the work of many satellites. Some went to look at the inferior planets while others looked at the superior planets. Two major satellites were Galileo and Cassini. Galileo is most famous for studying Jupiter and its moons. It provided scientists with beautiful images of Jupiter’s moons as well as the celestial body itself. The satellite ran on nuclear power, and played part in the day we nuked Jupiter in 2003. As Galileo ended its mission, scientists got the idea of crashing the satellite into something. They did not want to crash it on Europa (one of the moons) because it was a prime suspect of containing life, so they decided to have it fly into Jupiter. Galileo’s set collision course proved to be a fascinating end as it flew into Jupiter’s thick atmosphere and exploded with the same power as an atomic bomb. Despite its end, the mission gathered lots of useful information as did Cassini when it studied Saturn. The biggest thing launched into space at this time however, was the Hubble Space Telescope. The Hubble Space Telescope captured astronomical pictures that surprised all scientists. Everything seen by the telescope can be seen with the human eye, and in seeing all the colors, dust, gas, stars, etc. one cannot not be amazed. One of the most important things though, was the Hubble Deep Field. The telescope focused on one point looking into space which to the human eye looked as if there was nothing there. To the astonishment of the scientists there was much, much more than nothing. The picture on the right depicts the Hubble Ultra Deep Field, a second image taken in 2004 that goes into more detail. Each speck of light is a totally separate galaxy, one just as big or bigger than the Milky Way. This image just helps stress how large the universe actually is. It also helped
