New submitter ihtoit writes "Astronomers using the ALMA radio telescope in Chile have released images and data showing the oft-postulated but unobserved (until now) dust shell ejected by the supernova remnant SN1987A. 'We have found a remarkably large dust mass concentrated in the central part of the ejecta from a relatively young and nearby supernova,' astronomer Remy Indebetouw, of the National Radio Astronomy Observatory (NRAO) and the University of Virginia, said in a statement. 'This is the first time we've been able to really image where the dust has formed, which is important in understanding the evolution of galaxies.' SN1987A was the first cataloged supernova event in our Galactic neighborhood in 1987. It lies 168,000 light years (987 quadrillion miles) away in the Large Magellanic Cloud, which means that at the time of the explosion, woolly mammoths still roamed Europe and Mitochondrial Eve saw her first sunrise."
From the article, the significance: "'Really early galaxies are incredibly dusty and this dust plays a major role in the evolution of galaxies,' Mikako Matsuura, a scientist associated with the study ... said ... 'Today we know dust can be created in several ways, but in the early universe most of it must have come from supernovas. We finally have direct evidence to support that theory.'"Read Replies (0)

Nerval's Lobster writes "If you're a small-to-midsize tech company, CES isn't exactly the best place to get noticed. Every January, thousands of developers and startup executives flood Vegas with dreams of a big score. But they're not headed to the poker and blackjack tables in pursuit of that filthy lucre—instead, many of them have dropped thousands of dollars on a booth at the Consumer Electronics Show (CES), arguably the highest-profile technology conference of the year. (In addition to the tens of thousands of dollars it costs to reserve a space on the convention-hall floor, that money goes to demo units, flying employees to Vegas, and much, much more.) If they haven't managed to secure a spot in one of the Convention Center's massive halls, they've set up a demonstration area in a suite at some hotel on the Strip. And if they're too under-capitalized or unprepared for a hotel, they're lurking in the Convention Center parking lot. Seriously. It's a little insane. But in a certain way, you can't blame the startups: at some point, someone told them that CES is the best way to get their company noticed, even if it means blowing the equivalent of three employees' yearly salaries. On paper, the get-a-booth strategy makes sense—aside from SXSW, CES hosts possibly the greatest concentration of tech journalists in a relatively small space. What many first-timers don't realize (until it's too late) is that startups have a hard time standing out amidst the chaos: there are too many companies at too many booths attempting to sell (at top volume) too many variations of the same core ideas. If that wasn't bad enough, a fair portion of those companies are trying to draw attention with flashing screens, giveaways, music pumping at top volume, and other gimmicks. (Hey, it's Vegas.) So not only does your Nike FuelBand knockoff need to compete against a hundred other 'smart bracelets' on display, but you somehow need to make yourself visible despite the plus-size Elvis impersonator belting out 'Don't Be Cruel' in front of that chip-vendor's booth a few steps away. That's just the sort of quixotic endeavor that would drive even the most stalwart startup founder to drinking before 9 A.M."Read Replies (0)
