The stuff of life on Mercury
Mercury, the closest planet to the sun, has blistering 800-degree temperatures at its equator—but its poles are full of ice. New data from NASA’s Messenger spacecraft, which began orbiting Mercury last year, has revealed that as much as a trillion tons of ice exists in shadowy polar craters, where temperatures can drop to minus 370 degrees. Much of the ice […]

Giant chunks of manmade space junk regularly fall to Earth. It has been reported that only one person has been hit by falling debris and she was not hurt. According to a Harvard University astronomer rocket parts and satellites that weigh two tons, or more are falling uncontrollably to the earth about once a month. If you go back a […]
Read moreGold’s cosmic origins
All the gold on Earth was forged in the collisions of massively dense stars billions of years ago. Astronomers have come to this conclusion after observing and analyzing the afterglow of a crash between two neutron stars in a galaxy 3.9 billion light-years away that yielded a hoard of gold likely equal to the mass of 20 Earths. “At today’s […]
Read moreWhen the Red Planet was partly blue
Astronomers have found the strongest evidence yet that ancient Mars had a massive ocean for millions of years— an indication that the Red Planet once had everything necessary to support life. Shortly after Mars formed 4.5 billion years ago, NASA scientists say, the planet was wet, with enough water to cover the entire planet to a depth of about 450 […]

The Milky Way and its closest neighbor, the Andromeda galaxy, are on course for “ a head-on collision,” says astronomer Roeland van der Marel of the Space Telescope Science Institute. But no need for precautions because the crash won’t happen for another 4 billion years. Researchers have long known that Andromeda, currently some 2.5 million light-years away, is moving toward […]
Read moreOur sun’s hotter sister
Stars are not born alone. Rather, they emerge from clouds of gas and dust in groups of up to 10,000, then slowly scatter through space. For the first time, astronomers have identified a star that came from the same solar nursery as our sun, some 4.5 billion years ago. This stellar relative—located 110 light-years away in the constellation Hercules—is hotter […]
Read moreAstronomical Declaration
Scientists have made an astronomical declaration, stating that there is likely ten times the amount of galaxies in our universe than originally expected. The previous amount was believed to be about 200 billion, but now it is believed to be much more. According to astronomers from the University of Nottingham, we are just beginning to learn exactly how vast our […]
Read moreMystery Crater In Nicaragua
Mystery crater: A 40-foot crater has appeared in the ground near Managua airport. Nicaraguan authorities said the hole was caused by a meteorite that broke off from the passing Pitbull, or 2014 RC, asteroid. But NASA officials said that was unlikely, because such a strike would have produced an enormous fireball streaking across the sky, yet nobody reported seeing anything […]

On the 35th anniversary of its launch, the Voyager 1 spacecraft is close to becoming the first man-made object to escape our solar system. The spacecraft—run by a 1977 computer 100,000 times less powerful than an iPod Nano—is currently 11.3 billion miles away. In 2004, Voyager 1 entered the turbulent boundary zone beyond Pluto, where solar winds encounter plasma pushing […]
