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)

Scientists studying Martian clouds have created them right here on Earth. Using a cloud chamber in Germany and rock from the Mojave Desert, their experiment shows that the Red Planet's ice clouds often need far more humidity to form than clouds on Earth. The findings, published in the Journal of Geophysical Research: Planets, show that Martian clouds form under very different conditions than many scientists once thought - which may help researchers to better understand the planet's water cycle.

The Happiest All-Nighter on Earth? Hundreds of people flocked Friday to Disneyland and Disney California Adventure Friday, which opened for 24 straight hours beginning at 6 a.m. The Magic Kingdom Park in Orlando, Fla., was also opened for the "Monstrous Summer All-Nighter," part of the promotion for the entertainment giant's upcoming movie, "Monsters University. " The event marked the first time all-night opened for all three parks, Disney officials said. The last 24-hour event at Disneyland -- on Leap Day 2012 -- caused several headaches after a large after-work crowd overwhelmed the park , prompting officials to close gates for several hours.

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.

Billed as "the largest collaboration of media creation in the world's history," "One Day on Earth" is a compilation documentary built for these short-attention-span times. Drawn from 3,000-plus hours of footage from every country on the planet, taken by volunteer videographers on a single day in October 2010, the film is driven by a we-are-the-world connectedness, but remains a travelogue in search of a defining center. FOR THE RECORD: "One Day on Earth": A review of the film "One Day on Earth" in the June 22 Calendar section referred to an image of a Ukrainian bride's painted face.

A group of international scientists is sounding a global alarm, warning that population growth, climate change and environmental destruction are pushing Earth toward calamitous - and irreversible - biological changes. In a paper published in Thursday's edition of the journal Nature, 22 researchers from a variety of fields liken the human impact to global events eons ago that caused mass extinctions, permanently altering Earth's biosphere. "Humans are now forcing another such transition, with the potential to transform Earth rapidly and irreversibly into a state unknown in human experience," wrote the authors, who are from the U.S., Europe, Canada and South America.
