Blog Post 4: Lucy In The Sky With Diamonds

Normally, I post the interesting new discoveries about the universe that are very current. I found out about a discovery made in 2007 and it’s just as amazing!

Just 50 light years away, in the constellation Centaurus, is a star that used to go by the name of “BPM 37093”, a pretty generic name for matter in the Universe. The Harvard-Smithsonian Center for Astrophysics had discovered this to be a mass of crystallized carbon and now it is know as the biggest diamond in the galaxy! The star is now named “Lucy”, after the Beatles song “Lucy In The Sky With Diamonds.” Lucy isn’t so generic anymore!

This diamond is estimated to be a about 2,500 miles across. Lucy also is made up of 10 billion-trillion-trillion-carats. For a visual, this number written out is; 10,000,000,000,000,000,000,000,000,000,000,000. I know plenty of girls who are satisfied with just a couple carats in their diamond jewelry, let alone 10 billion-trillion-trillion! The article says that Bill Gates and Donald Trump combined couldn’t even be able to afford Lucy!

Five billion years from now, our sun will die out just like Lucy did and it will become a white dwarf with a hot crystallized center, just like Lucy is right now. So, we will have a large diamond in the center of our solar system when we are all long gone! How cool.

I think this is amazing. Diamonds are so beautiful and so scarce but, to know that 50 light years away there is so much of it just floating in space….such a remarkable thing to think about.
