Chunks Of The Milky Way Galaxy Are Being Sucked Away
Something unidentified, larger than anything in the known universe, is sucking portions of our galaxy away. In 2009, a group of galaxy clusters were found to be moving at an extraordinary speed towards a small patch of sky between the constellations of Centaurus and Vela. Scientists have dubbed this phenomenon "dark flow" in reference to other cosmic mysteries, dark matter and dark energy.
A Giant Black Hole Is Hurtling Through Space At 5 Million Miles Per Hour
The Hubble Space Telescope located a black hole in 2017 that is being manipulated by gravitational waves. The black hole––capable of devouring anything in its path––will eventually break free of its own galaxy and begin to roam the universe. Although the anomaly weighs as much as 1 billion suns and has reached speeds of roughly 5 million miles per hour, it is estimated to still be 8 billion light-years from Earth.
Astronauts Must Drink 730 Liters Of Recycled Sweat And Urine To Live In Space For A Year
Water is a limited resource in space––because of this, astronauts must resort to recycling their own waste. NASA astronaut Scott Kelly consumed approximately 730 liters of recycled urine and sweat during his yearlong mission.
The Night Sky Will Someday Be Completely Black
As the Milky Way Galaxy continues to merge with its neighboring galaxies, the view of the night sky from Earth will change dramatically. The speedy expansion will eventually pull the galaxies apart faster than light, eliminating the distinctive products of the big bang and nullifying points of reference for expansion measurement.
