Honestly admit that whether you still feel like a speck in this grand universe? Hold on, the galaxies look like a speck in here [ rest we can't imagine!].
The above image is the result of a 10 year long project dedicated to charting out a 3D Map of the Universe by researchers at the Harvard-Smithsonian, Center for Astrophysics. The map features more than 43,000 galaxies and includes elements within 380 million light years from the Earth. “In this projection, the plane of the Milky Way runs horizontally across the center of the image.” [Click on the above image to enlarge.]
The 3D mapping was possible with the 2MASS Redshift Survey (2MRS), which is a method of estimating how far the galaxies are from the earth as also from each other using the phenomenon called redshift. Data was continuously aggregated using telescopes located at Arizona and Chile.
