Snug in Earth’s orbit, Hubble is free from the background glare that earthly telescopes must fight to see the stars. This allows its supersensitive camera to take better photos of galaxies farther away—and thus much dimmer—than any optical telescope on the ground can. But despite being closer to the moon than any other telescope, there’s no way the scope could snap a photo of that one small step man took 40 years ago.

Sorry, vinyl aficionados, but CDs most accurately capture the clarity of musical performances. If you look at the grooves of a standard long-play record, or LP, through a microscope, you’ll see that each is filled with what look like rolling hills. These are, in fact, an extremely close replication of the shape of the sound waves from the musician’s instrument. But because the needle that carves the groove is shaped slightly different than the needle that reads it, the LP will never sound exactly like the original performance.

Next-generation super-phones won’t just be slimmer versions of today’s devices; they will be entirely different machines. Chipmakers are reinventing every processor that powers your portable. From PS3-quality videogames to built-in cameras that can fill in for your current point-and-shoot, a chip for it is in the works. And thanks to shrinking transistors, the new phones won’t be any larger or more power-hungry than today’s ultrathin models. Below, we've pulled together the technologies being released in the next year and a half to build the smartest smartphone possible.

When the Weatherbird II cruised up the Potomac River and into the nation's capitol in March of last year, spirits were high. The freshly painted 115-foot research vessel was about to set sail for what would be the world's first for-profit effort to "fertilize" the ocean with iron, growing a vast forest of marine plant life that would pull the greenhouse gas carbon dioxide from the atmosphere. The lap through Washington was an effort to drum up support for the voyage to the iron-deficient waters west of the Galápagos Islands.

With global warming grabbing headlines, carbon-free nuclear power is gaining popularity—and with it, concerns over what to do with the spent uranium fuel. The largest long-term burial project, Yucca Mountain, has stalled, and even though uranium’s first trip through a reactor extracts only 5 percent of its energy, power plants in the U.S. don’t reprocess fuel. This is mainly because the most common form of uranium, an ion called uranyl, is extremely difficult to extract from the spent fuel rods. But a new Pac-Man-like molecule could change that.

Paintball has become the perfect way for gadget geeks to unleash their inner Rambo. The latest carbon-dioxide- or compressed-air-powered guns, known as “markers,” have computerized controls and electronic firing mechanisms that can blast out 1,200 balls a minute at speeds of up to 300 feet per second. Add in a quick reloader and a sneaky scope, and your buddies won’t stand a chance.

Along with satellites and space stations, Earth is surrounded by tens of millions of pieces of floating space debris. Like any landfill, the trash is diverse, ranging from dead satellites to castaway rocket parts to flecks of paint. On average, over the past 40 years, one piece of space junk has fallen to Earth every day.
