Koeiemorgen allemaal!
Na het nieuws van gister over het onbekende signaal liet ook Seti@home zich horen:
SETI@home: "Baffling" "signal" "from HD 164595" is probably none of the above.
I'm sure that many of you have seen the news reports of a "SETI signal" detected from the star HD 164595
I was one of the many people who received the the email with the subject "Candidate SETI SIGNAL DETECTED by Russians from star HD 164595 by virtue of RATAN-600 radio telescope." Since the email did come from known SETI researchers, I looked over the presentation. I was unimpressed. In one out of 39 scans that passed over star showed a signal at about 4.5 times the mean noise power with a profile somewhat like the beam profile. Of course SETI@home has seen millions of potential signals with similar characteristics, but it takes more than that to make a good candidate. Multiple detections are a minimum criterion.
Because the receivers used were making broad band measurements, there's really nothing about this "signal" that would distinguish it from a natural radio transient (stellar flare, active galactic nucleus, microlensing of a background source, etc.) There's also nothing that could distinguish it from a satellite passing through the telescope field of view. All in all, it's relatively uninteresting from a SETI standpoint.
But, of course, it's been announced to the media. Reporters won't have the background to know it's not interesting. Because the media has it, and since this business runs on media, everyone will look at it. ATA is looking at it. I assume Breakthrough will look at it. Someone will look at it with Arecibo, and we'll be along for the ride. And I'll check the SETI@home database around that position. And we'll all find nothing. It's not our first time at this rodeo, so we know how it works.
Het lijkt dus op een magnetronsignaal van een researcher die even zijn kop koffie opwarmde of zo..
Maar goed.. vond het wel weer spannend.. wachtend op het "verlossende woord" dat het (n)iets was.
Los van het bovenstaande is het volgende nieuws:
Amerikaanse astronomen hebben een 3D-kaart gemaakt van ruim 70.000 sterrenstelsels op verschillende afstanden van de aarde. De verste stelsels bevinden zich op ca. 12 miljard lichtjaar afstand; we zien ze zoals ze er minder dan twee miljard jaar na de oerknal uitzagen. De nieuwe dataset, ZFOURGE geheten (FourStar Galaxy Evolution Survey), biedt een schat aan informatie over de evolutie van sterrenstelsels in de loop van de milajrden jaren. De waarnemingen zijn verricht met de FourStar-camera, een gevoelige infraroodcamera op de 6,5-meter Baade-telescoop van het Magellan Observatory op Las Campanas in Noord-Chili. Verrassend resultaat van de survey is dat sterrenstelsels in de relatief prille jeugd van het heelal ook al een grote verscheidenheid vertoonden. Ook werd een jonge cluster van sterrenstelsels ontdekt, die al was ontstaan toen het heelal nog maar drie miljard jaar oud was. Op basis van de nieuwe resultaten, gepubliceerd in The Astrophysical Journal, concluderen de onderzoekers dat ons eigen Melkwegstelsel zo'n 12 miljard jaar geleden veel kleiner moet zijn geweest dan nu, maar dat er wel sprake was van een ca. dertig maal zo hoge stervormingsactiviteit.
Vandaag hebben we eindelijk weer wat mijlpalers! En niet de minste:
