Hubble identifies unusual wrinkle in expansion rate of the universe

(CNN)Measuring the expansion rate of the universe was one of the Hubble Space Telescope's main goals when it was launched in 1990.

Over the past 30 years, the space observatory has helped scientists discover and refine that accelerating rate -- as well as uncover a mysterious wrinkle that only brand-new physics may solve.

Hubble has observed more than 40 galaxies that include pulsating stars as well as exploding stars called supernovae to measure even greater cosmic distances. Both of these phenomena help astronomers to mark astronomical distances like mile markers, which have pointed to the expansion rate.

In the quest to understand how quickly our universe expands, astronomers already made one unexpected discovery in 1998: "dark energy." This phenomenon acts as a mysterious repulsive force that accelerates the expansion rate.

1. how can they say the univese "expands"

when they don't even know where it "ends"

sorta like the flat earth society?

2. My daughter, terrible with math, but loves everything space...

Was visiting Yerkes observatory in Williams Bay, WI and a caretaker of the building offered her a tour inside, more indepth than she had seen before. She was able to see some of Hubble's papers that were stored there when he had been working, and a globe they projected the space flights on. She was over the moon.


If you are ever in the Lake Geneva, WI area, it is a must see. Incredible history was made there.
