NASA has discovered there may be a lot fewer galaxies than initially believed, opening up the possibility that humans are alone in the universe. The data provided by New Horizons Mission determines that the number of galaxies is anywhere in the hundred billion range rather than 2 trillion as supposed initially.
The new findings are in stark contrast to the 2 trillion figure which had been long used. According to the data provided by the Hubble telescope. Scientists use a mathematical model to determine that 90% of the galaxies in the universe are beyond the “visible light” observed by the Hubble telescope.
The $720 million New horizon spacecraft launched in 2006, traveling roughly at 33,000 miles per hour, will eventually enter interstellar space. Being at the edge of the solar system, it’s able to see ambient light 10 times darker than the Hubble Telescope’s vantage point. “These kinds of measurements are exceedingly difficult. A lot of people have tried to do this for a long time,” the study’s co-author, Tod Lauer, explained. “New Horizons provided us with a vantage point to measure the cosmic optical background better than anyone has been able to do it.” Lauer also added, “Take all the galaxies Hubble can see, double that number, and that’s what we see – but nothing more.”
