FREE EBOOK FROM NASA ON THE "DARK UNIVERSE"

Hey, Space Placers!

As described by NASA:

NASA’s Hubble Space Telescope team has released a new downloadable e-book in the Hubble Focus series, called “Hubble Focus: The Dark Universe.” This e-book highlights the mission’s recent discoveries about two mysterious components of our universe, known as dark energy — an unexplained cosmic pressure that’s speeding up the universe’s expansion — and dark matter, an invisible substance detectable only by seeing how it gravitationally influences visible matter.

A highly enjoyable and informative read!
