Hours before their special news conference today, the cat is out of the bag: NASA has discovered a completely new life form that doesn’t share the biological building blocks of anything currently living in planet Earth. This changes everything.
At their conference today, NASA scientist Felisa Wolfe Simon will announce that they have found a bacteria whose DNA is completely alien to what we know today. Instead of using phosphorus, the bacteria uses arsenic. All life on Earth is made of six components: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. Every being, from the smallest amoeba to the largest whale, share the same life stream. Our DNA blocks are all the same.

How many stars in the universe? Maybe 300 sextillion | Seattle Post Intelligencer

There might be three times more stars in the universe than astronomers thought. That’s the gist of a report published Wednesday, which says scientists may have vastly underestimated the number of red dwarf stars.
According to the report, it’s likely there are about 300 sextillion stars in the universe. A little perspective: That’s the number you get when you multiply 3 trillion by 100 billion.
