This was an interesting year for science. But rather than stretch for a list of the top ten accomplishments or discoveries I would like to focus in on three specific feats of technological achievement that, I think, have broad implications both for the future of science and how humanity views itself.
I begin with the discovery of hundreds of exoplanet candidates in our galaxy. This does not mean that astronomers have found hundreds of exoplanets (though, with 100 billion stars in the Milky Way, it’s safe to assume that there are at least billions of planets). Rather, using indirect measurements, astronomers have found what look to be planets. As better telescopes (well, spectrographs) come online, astronomers will be able to confirm whether these are in fact planets.
There was one other very interesting find when it comes to exoplanets. In September one team of researchers was able to identify the first exoplanet known to hold liquid water. However, this discovery was contested when a second team could not find the planet. Whether the planet does exist and does contain water will remain in question; however, there is no question that somewhere out there exist other planets that do contain liquid water. Astronomers are currently looking for planets that have “biomarkers,” or the correct elements and compounds that would allow for life. Carbon. Oxygen. Water. Methane. Carbon dioxide. As well as uranium, potassium, and thorium to allow for tectonic activity. It may very well be that life exists within our solar system (Europa, Titan, Io, and Enceladus are all candidates). read more »
