Scientists Discover The Oldest, Largest Body Of Water In Existence--In Space Scientists have found the biggest and oldest reservoir of water ever--so large and so old, it’s almost impossible to describe. The water is out in space, a place we used to think of as desolate and desert dry, but it's turning out to be pretty lush. Researchers found a lake of water so large that it could provide each person on Earth an entire planet’s worth of water--20,000 times over. Yes, so much water out there in space that it could supply each one of us all the water on Earth--Niagara Falls, the Pacific Ocean, the polar ice caps, the puddle in the bottom of the canoe you forgot to flip over--20,000 times over. The water is in a cloud around a huge black hole that is in the process of sucking in matter and spraying out energy (such an active black hole is called a quasar), and the waves of energy the black hole releases make water by literally knocking hydrogen and oxygen atoms together.
Timeline of the Universe | Future | Timeline The hypernova of Eta Carinae is affecting our region of the galaxy Eta Carinae is among the largest, most volatile stars in our galaxy. Its temperature is so high that it is unable to hold onto its own gas, with constant streams being ejected from the surface. It first came to attention in 1843 when it flared to magnitude -0.8, becoming the second brightest star in the night sky. It subsequently died down, before brightening again in the late 1990s. This fluctuation continues – with periodic flaring and dimming – until one day the inevitable happens.
