One of the most accurate census for galaxies was recently achieved by astronomers that used various observatories, such as the Hubble Space telescope. The recent calculation of galaxies is insanely higher than our previous calculation.
On the side of the earth, where you can visibly view the universe, there are 10-20 times more galaxies than the last estimation. This calculation totals out to almost two trillion galaxies. The recent total was estimated at 100 billion galaxies. By learning this number, there is a need to recalculate the number of stars that exist in the universe. The current number of stars sits at 700 sextillion. 23 zeros that follow the number 7.
This amount only comes from the part of the universe that can be seen. With 13.8 billion years in age, astronomers can only see so far into the universe. Once you go outside the Hubble telescope, everything else is blind to the eyes. There still hasn’t been enough time for the objects to deliver light to those on planet earth. In reality, it is impossible to know the exact amount of galaxies that actually do exist.
Christopher Conselice directed an international team of astronomers to utilize deep space images found through their telescope and combined it with the information of other astronomers. The team had the images converted into 3-D images. This gives researchers the opportunity to produce measurements that are more accurate for the number of galaxies, throughout various stages of the universe history.
Peering back in time, astronomers were able to see how the universe was once filled with numerous little galaxies. These small galaxies would eventually merge together and produce greater objects, which are visible today. A recent celestial survey will display how much galaxies have evolved throughout the history of the universe.
After learning the huge addition of the galaxies that exist in the universe, Conselice went on to say, “It boggles the mind that over 90% of the galaxies in the universe have yet to be studied. Who knows what interesting properties we will find, when we discover these galaxies with future generations of telescopes.”
