One of the real celestial treats through any size telescope is the giant planet Jupiter. Even a 2-inch scope will let you view its main markings and four largest moons. By watching the moons change their positions night after night, you can experience “real-time” astronomy. That would be a good start. If, however, you want to go deeper into Jupiter observations, I recommend Jupiter and How to Observe It by John W. McAnally (Springer, 2008). Even before...

People love to jump on NASA when things aren’t going so hot for the space agency. Do you remember the reaction of some when the Hubble Space Telescope had its early hiccups? This is the same crowd that ignores NASA’s amazing successes, such as the twin rovers on Mars , Stardust catching a comet, Cassini revealing the saturnian system, and years of amazing images from Hubble . Recently, the media picked up a story about a 13-year-old German student...

On Tuesday evening, April 8, you can experience one of the most beautiful events the sky can deliver. Head outside no later than an hour or so after sunset (around 8:30 P.M. local daylight time) and look to the west. Your eyes should land immediately on the slender crescent Moon, oriented with its cusps standing nearly straight up from the horizon. Point your binoculars at the Moon to reveal a stunning sight: the bright Pleiades star cluster (M45...

There’s no better place to find astronomy related software than the web archive created by Astro Events Group of Ostend, Belgium. “Our compilation will actually never be complete,” says Patrick Jaecques, a member of the group. “We have updates about every week. It’s also the only part of our Dutch web site that is translated into French, German and English.” There you’ll find hundreds of programs for a wide variety of computing environments, including...

It seems to me that Saturn’s moon Rhea is a leading candidate for Rodney Dangerfield of the solar system. I tell you, it doesn’t get much respect. Even in the Saturn system, where Rhea is the second-largest moon, it ranks pretty low. You hear about Titan, with its thick atmosphere and methane lakes. Enceladus is known for its liquid-water geysers and Iapetus for its strange black and white hemispheres. Even tiny Mimas, with its cute “Death Star” crater...

On November 7, Japan’s SELENE spacecraft captured this high-definition image of Earth rising over the Moon’s north pole. JAXA/NHK If prime-time television, National Geographic specials, and sports programming don’t get you pumped for seeing TV at the highest-possible resolution, then what else is there? Television may not be the “vast wasteland” it once was claimed to be, but you could make a good case that seeing incredible detail in TV’s moving...

This just in from the hydrocarbon desk at Astronomy.com: Titan’s surface lakes and methane-ice-laden dune seas collectively hold hundreds of times Earth’s bounty of hydrocarbons (oil and gas). It’s a Texas oilman’s dream: hydrocarbons rain from the sky on Titan. To my mind, this could solve a lot of problems. Planetary scientists have been competing with NASA’s fantastically expensive manned space program for decades. Word on the aerospace street...

Before the International Astronomical Union ’s (IAU) 2006 demotion of Pluto, many schoolchildren remembered the solar system’s planetary progression with mnemonics, including “My Very Educated Mother Just Served Us Nine Pizzas.” Following the IAU’s solar system tweaks, kids need a new memory aid. Recently, National Geographic Children’s Books held a contest asking children to submit their new mnemonic. This inclusive contest asked kids to list dwarf...

In 1967, Roger Patterson and Robert Gimlin captured the famous footage of what many cryptozooligists and kooks believe is Bigfoot. Perhaps sick of urban sprawl, the Patterson-Gimin Sasquatch relocated to the Red Planet. In a panoramic image captured by the Mars Exploration Rover Spirit in November 2007, a Bigfoot-like figure appears among the surface formations. The Internet grabbed hold of this photo around the beginning of 2008, and bloggers have...

Duck! There’s another near-Earth asteroid coming! You may have noted the media reports this week about the asteroid 2007 TU24 , which makes a close pass by our home planet next Tuesday (January 29). But don’t worry too much, because I mean “close” in astronomical terms, which in this case is 1.4 lunar distances (334,000 miles). Or perhaps a friend of yours forwarded a goofball hoax e-mail to you about the government conspiracy (only one?) to hide...
