This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. The sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy through nuclear fusion as it does now. The death of the sun is often thought of …

A human-occupied vehicle (HOV) probing the deep Pacific Ocean has cast a light upon a massive undersea ‘metropolis’. The tortuous system of deep craters and dolomite walls blows the Atlantic Ocean’s famous ‘Lost City’ out of the water. Through a curtain of falling marine ‘snow’, the ghostly carbonate walls and jagged rocks around twenty hydrothermal vents shimmer in the heat …

White dwarfs — the superdense, slowly cooling embers left behind when stars like our sun die — are usually quiet cosmic relics. A rare few, however, are anything but. In recent years, astronomers analyzing data from the European Space Agency’s Gaia spacecraft identified a handful of white dwarfs hurtling through the Milky Way at breakneck speeds of up to 1,240 …

Scientists Found an Undersea Metropolis That Dwarfs the Atlantic’s ‘Lost City’  AOL.comView Full Coverage on Google News Source link

Here’s what you’ll learn when you read this story: Researchers believe the earliest forms of life on Earth began in hydrothermal vents—cracks in the sea floor that release hot, mineral-rich water. A team of scientists just discovered a hydrothermal system that’s 100 times larger than the famously massive Lost City system in the Atlantic Ocean. The study suggests that the …

Scientists have stumbled upon four new species of tarantulas whose males have such outrageously long genitals that they had to invent an entirely new genus to classify them: Satyrex, named after the mythological satyr—half-man, half-goat, all libido—and the Latin word for king, rex. The males of the newfound species boast palps (spider sperm-delivery appendages) that stretch up to four times …
