SKA radio telescope to pump out more data than the internet in 2020, spot ALF before he lands
Unfortunately for Desmond Dekker fans, this SKA telescope has nothing to do with the Jamaican music sensation. No, the Square Kilometer Array (SKA) radio telescope has much more otherworldly concerns, and according to the director of the International Centre for Radio Astronomy Research (ICRAR), Peter Quinn, it should have the internet beat in terms of data when it goes online in 2020. The telescope, which will end up in either Australia, New Zealand, or South Africa, is aimed at searching for Earth-like planets, extraterrestrial life, dark matter, and black holes, and will require a central supercomputer with "the processing power of one billion PCs." What's more, it is expected to be 10,000 times more powerful than any telescope in existence and "generate the same amount of data in a day as the entire planet does in a year." We say anything that gets us closer to having our very own hairy, Hawaiian-shirt sporting alien on hand is well worth the $2.1 billion it will cost to create. Willy!
Astronomers snap black hole murder in graphic detail (video)
We tend to imagine a black hole sucking everything around it straight into oblivion. The truth, however, is even more gruesome. Astronomers have just captured an ultra hi-res image of our neighbouring galaxy, Centaurus A, and it helps to reveal what actually happens. Matter is yanked helplessly towards a black hole at the galaxy's core, but it refuses to die quietly. For some unknown reason, it erupts as it falls, spewing out vast plumes of particles -- like blood from celestial murder. These death throes emit radio waves, allowing us to witness them using radio telescopes even though we are 12 million light-years away. If only we were closer; if only we could intervene. Alas, all we can do is watch the video after the break and hit the source links for a fuller explanation -- though, admittedly, none of those sound like awful options.
Save Arecibo: because aliens don't do voicemail
The folks at SETI@home have put out a desperate plea for the community to bust out those quill pens and start writing strongly-worded letters to congress persons. Apparently the Arecibo Observatory, the world's largest radio telescope and SETI@home's data source, is being threatened with some massive budget cuts. Given that a replacement for Arecibo won't be online until 2020 at best, folks are understandably upset. Turns out Arecibo is also one of the best shots we have at detecting an earth-threatening asteroid before it's too late and we have to sit through another Elijah Wood movie on the subject. You know what you have to do.[Thanks, Brian]
