Home, sweet home. A new discovery published today in Nature, shows that our galaxy, the Milky Way, is part of an enormous supercluster of galaxies. The name they have chosen for this supercluster is Laniakea, a word that comes from the Hawaiian words for “immeasurable heaven.” Stretching over 500 million light years across and containing over 100,000 galaxies with the mass of a hundred million billion suns, this new structure is the biggest gravitational object we know. All our structure is defined by gravity – without it there would be nothing – no planets, no stars, no galaxies, nothing. But at the largest sizes bigger than galaxies, another force kicks in – the mysterious dark energy that seems to accelerating the universe expansion.

Now scientists have a detailed enough understanding of the balance between gravity and dark energy to make our biggest ever map of our locality. And now we knowledge our full cosmic address does not end at our galaxy. Now we’re proud citizens of Laniakea. Better get your passport.

  1. Definitely lets you release just how small Earth is in this entire universe of ours. Would be very interesting to see how they came to this conclusion. Also can’t wait to see what other mind-boggling things we discover in the future about this ever expanding universe of ours.

  2. Wow! That’s amazing. How did they find this discovery? Was it new or barely found? And I love the name, sounds so fitting for a supercluster of galaxies. What exactly would this look like? It’s miraculous how scientists and the technology that we have in this century doesn’t limit how much we can know about the milky way – I mean it does to some extent but we are so fortunate to have the things we do to locate beautiful wonders like Laniakea.

  3. I thought that the energy that created all of these galaxies and superclusters was amazing but dark energy is almost impossible to imagine. It is incredible how powerful it is and we still have no idea what it is exactly. Learning about how vast the universe is, makes one think that there are possibly millions upon billions of other life forms out there and we might only be a small glimpse in history.

  4. Wow it is so amazing and interesting to know there is more to our “home”. Discovering that our Milky Way is part of a supercluster of galaxies makes you wonder how much more to it is out there.

  5. Should we update our cosmic address?

    It’s fascinating to hear about new discoveries, especially ones that expand our knowledge about the world and universe around us here on our little rock known as earth. The video about our “home” supercluster is awesome and thought provoking!

  6. Its interesting that our milky way is at the out skirt of the super cluster, and that there are others around the super cluster like Virgo. So maybe there are living things out there in there solar system, because the gravity is almost the same there as our solar system.

  7. Now that we know that our Milky Way is apart of a super cluster of galaxies, we could find more observations that we haven’t known for a couple of years. Being the largest supercluster galaxy known, we could say that there are even bigger galaxies out in the “mysterious dark energy that seems to accelerating the universe expansion.”

  8. I really enjoy the fact that Laniakea was the chosen name for the supercluster because of its enormous size and Laniakea meaning “immeasurable heaven.” Also, the fact that without gravity there would be nothing, is absolutely mind-blowing. It really makes me wonder more about the big picture.
