New Moon System Around Uranus

An anonymous reader writes "Astronomers have discovered two of the smallest moons yet found around Uranus. The new moons, uncovered by NASA's Hubble Space Telescope, are about 8 to 10 miles across (12 to 16 km) -- about the size of San Francisco. The two moons are so faint they eluded detection by the Voyager 2 spacecraft, which discovered 10 small satellites when it flew by the gas giant planet in 1986. The newly detected moons are orbiting even closer to the planet than the five major Uranian satellites, which are several hundred miles wide. The two new satellites are the first inner moons of Uranus discovered from an Earth-based telescope in more than 50 years. "It's a testament to how much our Earth-based instruments have improved in 20 plus years that we can now see such faint objects 1.7 billion miles (2.8 billion km) away," says Mark Showalter, a senior research associate at Stanford University. 'The inner swarm of 13 satellites is unlike any other system of planetary moons,' says co-investigator Jack Lissauer. 'The larger moons must be gravitationally perturbing the smaller moons. The region is so crowded that these moons could be gravitationally unstable. So, we are trying to understand how the moons can coexist with each other.'"

    alternatively, they might eject of uranus orbit and become the next catalyzer of earthly protoplanet destruction killing every living creature and brining about a new cambrian era from which it would take millions of years to reinitialize suitable conditions for autogenesis. but then, who knows?

    This is Slashdot, where immature people come to comment about things they don't even know jack about. Where people hate Microsoft for no reason, where mice are used as pillows, and the Matrix is God. Where BSD and Solaris is dead, and the immature (in the truest sense of the word) Linux rules the kingdom. Where puppy dogs drown and people change their mind, taking it back, erasing and rewind. Where people bow down to CowboyNeal and the TV remote is always just out of reach. Where a VW bug is a unit of measurement and the metric system is the tool of the devil. Where the mouse button has replaced common sense and an IQ of 28 is unheard of.

    Microsoft Browser Holes Lead to AIM, Dial - Up Attacks
    By REUTERS

    Published: September 26, 2003

    Filed at 8:03 p.m. ET

    SAN FRANCISCO (Reuters) - Security holes in Microsoft's Internet Explorer browser have been exploited by hackers to hijack AOL instant messaging accounts and force unsuspecting Web surfers to run up massive phone bills, computer experts cautioned on Friday.

    Some Internet Explorer users are also finding that malicious Web sites are secretly slipping trojan programs onto their computers, which could prove an even more dangerous exploit, said Drew Copley, a research engineer at Aliso Viejo, California-based eEye Digital Security, who discovered the original security vulnerability.

    Such stealth programs can include keystroke loggers that record everything a person types or software to erase the hard drive, among other things, he said.

    "but can you think of a more sensible unit of size than San Francisco for an object in the vicinity of Uranus?"

    Kilometers are good. At least they're of fixed size, compared to San Fransisco which is of variable size, depending when you look and how you measure it.
