ST. PETERSBURG, Russia -- Ukrainian astronomers say an asteroid might collide with Earth in a couple of decades, a Russian news service reported Thursday. Space watchers from the observatory in the Crimean peninsula said they discovered an asteroid about 1,345 feet in diameter, which they call 2013 TV135, that is approaching Earth at a potentially dangerous trajectory, RIA Novosti said. The astronomers calculated the date of a potential collision as Aug. 26, 2032, the news service said, but they acknowledged the odds of an impact as 1 in 63,000.

On Thursday night, an asteroid about the size of a 14-story building will hurtle past Earth at the mind-bending speed of 7 miles per second. And one month ago, scientists didn't even know it existed.  Asteroid 2012 QG42 was just discovered on Aug. 26 by astronomers at the  Catalina Sky Survey in Arizona. It has been classified as a PHA (Potentially Hazardous Asteroid) by the Minor Planet Center based in Cambridge, Mass.  That sounds kind of scary, but scientists say there's no need to worry -- at least not yet. The asteroid is not expected to get closer to Earth than 7.5 x the distance of the moon from Earth.  (The moon's distance from Earth fluctuates, but it averages 230,600 miles)

Earthlings, get ready to say cheese! NASA's Cassini spacecraft will be taking your picture next month -- from 898 million miles away. If you happen to have your eyes closed or your hair is out of place, don't worry. All of planet Earth will fit into 1.5 pixels in the final image. Most of the frame will be filled by Saturn and its gigantic rings (though some of the edges will be cut off). Scientists at the Jet Propulsion Laboratory in La Canada Flintridge are taking the picture - actually, a mosaic of images - because they can. It just so happens that Cassini and the sun will be on opposite sides of Saturn, allowing the spacecraft to see the planet and its famous rings with unusual clarity.

How old is the Earth? Scientists say 4.5 billion years. But Sen. Marco Rubio (R-Fla.) isn't a scientist, so he's not sure. That's what the Republican rising star told an interviewer for GQ who posed the question. “I'm not a scientist, man,” Rubio, a member of the Commerce, Science and Transportation Committee, said. “I can tell you what recorded history says; I can tell you what the Bible says; but I think that's a dispute amongst theologians, and I think it has nothing to do with the gross domestic product or economic growth of the United States.” In case the interviewer didn't hear him the first time, Rubio added: “I'm not a scientist.

Early Thursday morning, solar observers watched as a dark spot on the sun erupted with an enormous flash of light, causing the biggest solar flare of 2013. Solar flares themselves don't last long, but this one was powerful enough to cause a bubble of solar material called a CME (coronal mass ejection) to come bursting off the sun. Up to billions of tons of that solar material is now hurtling through space at the mind-bending speed of more than 600 miles per second, and it is heading directly toward Earth.

It's 1.7 miles long. Its surface is covered in a sooty black substance similar to the gunk at the bottom of a barbecue. If it impacted Earth it would probably result in global extinction. Good thing it is just making a flyby. Asteroid 1998 QE2 will make its closest pass to Earth on May 31 at 1:59 p.m. PDT. Scientists are not sure where this unusually large space rock, which was discovered 15 years ago, originated from. But the mysterious sooty substance on its surface could indicate it may be the result of a comet that flew too close to the sun, said Amy Mainzer, who tracks near-Earth objects at Jet Propulsion Laboratory in La Cañada Flintridge . It might also have leaked out of the asteroid belt between the orbits of Mars and Jupiter, she said.

Looking for a sign that the Republican Party might have some leaders who can appeal to younger voters? Mitt Romney cited the Beach Boys, Garth Brooks and the Eagles among his favorite musicians, but Sen. Marco Rubio raised some eyebrows Monday with hat tips to N.W.A and Public Enemy. Rubio, 42, who has sparked early 2016 presidential hype with a headlining visit to Iowa over the weekend, spoke to GQ about a number of topics, but his opinions on music and the Earth's age overshadowed his perspective on President Obama and young Republicans.

Asteroid 4179 Toutatis will zip past Earth this week. At its closest approach Tuesday night and into Wednesday morning, it will come within 18 lunar distances of the planet. That's 18 times the distance from the Earth to the moon. That may not sound too close, but the asteroid's erratic orbit occasionally has it zipping by a little too close for comfort. That's why the asteroid has been designated "potentially hazardous. "  In 2004 for example, the asteroid's orbit took it even closer to the Earth -- just about four lunar distances.

Poring over images of Saturn's icy moon Iapetus, planetary scientists have discovered massive landslides in which the falling ice travels much farther than should be possible given the coefficient of friction of the falling ice. In one spectacular case in the moon's Malun crater, ice broke off the wall of the 5-mile-deep crater and surged 22 miles across the crater floor -- an unusually long distance. Given that cold ice has a relatively high coefficient of friction, such long distances should not be possible unless there are forces at work that researchers don't yet know about, said planetary scientist William McKinnon of Washington University in St. Louis, who led the team studying the landslides.

When producers of the upcoming science fiction movie "After Earth" wanted to create an image of what the planet might look like 1,000 years in the future, location manager Dow Griffith knew just the place. He immediately thought of the mystical redwood forests in Northern California where his parents had taken him on a camping trip as a child. "I wanted to be able to evoke that sense of what the Earth would be like a thousand years after man has left, and I always felt that these enormous trees would say that in one shot," Griffith said in an interview from his Santa Monica home.
