SETI has not found ET: official

Move along, nothing to see here


Astronomers at the SETI@Home project have spoken up to dismiss suggestions that the project intercepted signals from an alien civilisation.

Reports spread across the net yesterday and today after New Scientist said that an "interesting" signal had been picked up by the huge radio telescope in Arecibo, Puerto Rico.

The magazine quoted Dan Wertheimer, the chief scientist on the SETI@Home project, as saying that the signal was the most interesting yet identified by the project. He remarked: "We're not jumping up and down, but we are continuing to observe it."

Despite the otherwise sceptical tone of the article, his comments sparked speculation that we had actually made contact with another world. Sadly, this does not appear to be the case, and Wertheimer told ther BBC today that the idea of contact was "all hype and noise". "We have nothing that is unusual. It's all out of proportion," he said.

So the armies of the world can stand down - it was all a false alarm. There are no aliens trying to contact or destroy us, and we can all relax again. Phew.

The signal in question is dubbed SHGb02+14a, and has a frequency of about 1420 megahertz. This is also one of the main absorption frequencies of hydrogen. It is also the alien hunters' favourite place to go looking for deliberate signals from extra terrestrial civilisations.

The signal has only been observed on three occasions for about a minute each time. This is not really long enough for it to be analysed properly, scientists say, which means there are plenty of possible explanations for it.

Even discounting the suggestion that it is evidence of some natural phenomenon, scientists cannot rule out ground based interference, or the possibility that someone has hacked the SETI@Home program. ®

  • Everything you wanted to know about modern network congestion control but were perhaps too afraid to ask

    In which a little unfairness can be quite beneficial

    Systems Approach It’s hard not to be amazed by the amount of active research on congestion control over the past 30-plus years. From theory to practice, and with more than its fair share of flame wars, the question of how to manage congestion in the network is a technical challenge that resists an optimal solution while offering countless options for incremental improvement.

    This seems like a good time to take stock of where we are, and ask ourselves what might happen next.

    Congestion control is fundamentally an issue of resource allocation — trying to meet the competing demands that applications have for resources (in a network, these are primarily link bandwidth and router buffers), which ultimately reduces to deciding when to say no and to whom. The best framing of the problem I know traces back to a paper [PDF] by Frank Kelly in 1997, when he characterized congestion control as “a distributed algorithm to share network resources among competing sources, where the goal is to choose source rate so as to maximize aggregate source utility subject to capacity constraints.”

  • How business makes streaming faster and cheaper with CDN and HESP support

    Ensure a high video streaming transmission rate

    Paid Post Here is everything about how the HESP integration helps CDN and the streaming platform by G-Core Labs ensure a high video streaming transmission rate for e-sports and gaming, efficient scalability for e-learning and telemedicine and high quality and minimum latencies for online streams, media and TV broadcasters.

    HESP (High Efficiency Stream Protocol) is a brand new adaptive video streaming protocol. It allows delivery of content with latencies of up to 2 seconds without compromising video quality and broadcasting stability. Unlike comparable solutions, this protocol requires less bandwidth for streaming, which allows businesses to save a lot of money on delivery of content to a large audience.

    Since HESP is based on HTTP, it is suitable for video transmission over CDNs. G-Core Labs was among the world’s first companies to have embedded this protocol in its CDN. With 120 points of presence across 5 continents and over 6,000 peer-to-peer partners, this allows a service provider to deliver videos to millions of viewers, to any devices, anywhere in the world without compromising even 8K video quality. And all this comes at a minimum streaming cost.
