Travelling through space is a thought that I have often. How cool would it be to somehow travel across the universe, visiting new planets and worlds, discovering new forms life, new climates, new ways of existing?
While that prospect is something that I will likely never experience in my lifetime, I like to believe that mankind will get there someday. For now, we’ll have to use our imaginations, and maybe a bit of help from the most detailed map of our universe yet.
The team of scientists that created this amazing new map, led by University of Hawaii astronomer Brent Tully, presented their video at the “Cosmic Flows: Observations and Simulations” conference in Marseille, France, not long ago.
After watching the video, you will undoubtedly have a few existential thoughts. Not only does this new map plot out the distribution of all visible matter in local galaxies, but the invisible pieces as well (dark matter, for example, makes up about 80 percent of ALL matter in our universe).
Not to mention, they’ve discovered that our galaxy, the Milky Way (which has a 100,000 light-year diameter), is actually part of a much bigger supercluster of galaxies, known as Laniakea. Laniakea boasts an impressive 100,000 galaxies, and reaches almost 500 million light years across.
And it’s just one of several superclusters in the known universe. Wow.
What do you think about Laniakea and our new spacemap of the universe?
Please share with friends and family who would love to see just how big our universe really is!
