With temperatures in excess of 800 F, Mercury is one of the last places in the solar system you’d expect to find ice. But when NASA’s Messenger spacecraft transmitted its first optical images of the closest planets to the sun, that’s exactly what scientists discovered. Mercury sits about 36 million miles from the sun, which is roughly 57 million miles […]

Astronomers have discovered two clouds of gas some 12 billion light-years away that appear to preserve the primordial conditions of the universe in the minutes after the big bang. The clouds contain just hydrogen and its isotope deuterium, making them “the first examples to fit precisely” into what scientists think the early universe was like, University of California astronomer Jason […]

Two NASA probes that spent last year orbiting the moon have returned stunning new geological maps that could help explain how it, Earth, and other planets in our solar system formed. The probes, named Ebb and Flow, flew identical orbits just miles above the moon’s surface to measure its gravity field. Slight disruptions in their paths—caused by the push and […]

Imagine a pivotal scene from your favorite sci-fi alien invasion movie where their 50-foot wide laser beams destroy our buildings like sneezing on a pile of flour. What could we do? We’re merely meat muppets with pitiful silicon based technology. How could we ever hope to detect these aliens with their stealth spacecraft and 3rd stage guild navigators? If we’re […]

Thanks to the Hubble space telescope, it is nearly impossible to unsee the huge glimmering region on the surface of Uranus. The cause of this blatant smear on Uranus is caused by powerful bursts of solar wind. Streams of charged particles caught in powerful magnetic fields forced into the upper atmosphere of Uranus, where their interactions with gas particles, such […]

Stephen Hawking: ‘There are no black holes‘ – Renowned physicist Stephen Hawking has declared that black holes do not exist – at least not in the way we normally think about them. In a new paper, he tackles a scientific paradox regarding a black hole’s event horizon. This is the threshold past which nothing can escape it’s gravitational pull. Under […]

People always wonder how the moon was made. The birth of the planets 4.5 billion years ago was extremely violent. They grew to full size by absorbing rival planet embryos in a series of titanic collisions—one of which probably gave Earth its moon (below). The moon’s large size, low density, and other features suggest that it emerged from an explosion […]

Astronomers have spotted the most enormous black holes ever detected, inspiring new theories about how such pockets of extreme gravity form. Together, the two objects, which are roughly 300 million light-years away, have more mass than 30 billion suns, University of California at Berkeley astrophysicist Chung-Pei Ma tells the Associated Press. “They are monstrous,” she says. The smaller of the […]

Saturn’s moon Titan may be light-years away from Earth, but the two bodies have many characteristics in common: Wind, rain, volcanoes, tectonics and other Earth-like conditions all sculpt features on Titan, but act in an environment many times colder than Antarctica. “It is really surprising how closely Titan’s surface resembles Earth’s,” said Rosaly Lopes, a planetary geologist at NASA’s Jet […]
