Gli eventi studiati da LHC non sono cose “mai viste prima;” nell’atmosfera della terra arrivano miliardi di raggi cosmici provenienti dal sole o dallo spazio profondo e, collidendo con l’atmosfera, producono eventi molto più energetici di quelli di LHC, senza aver peraltro mai generato buchi neri - o forse il bilancio dell’Italia viene proprio da lì? […] LHC è un progetto nato 15 anni fa […] Ok, magari tutte le conclusioni raggiunte sono sbagliate e moriremo tutti, ma quantomeno non è una cosa “saltata fuori nell’ultima settimana.” Il fatto che i giornalisti si sveglino oggi perché hanno finito le tette e i culi da mettere in prima pagina non vuol dire che il problema non sia stato considerato seriamente dagli scienziati, sebbene, come hai detto tu, in ogni cosa si può nascondere un errore o semplicemente un’ignoranza dei fatti. […] Il 10 di settembre non succederà un bel niente. Non perché le nostre previsioni siano infallibili, ma semplicemente perché ci sarà solo un collaudo generale della macchina con fasci di particelle a bassa energia e nessuna collisione: il macchinone è costato un pacco di soldi e mica vogliamo fumarcelo al primo colpo!

[Researchers] believe that large galaxies such as the Milky Way contain supermassive black holes in their cores that drag dust and gas toward them in a disk and fling it back out via jets of ionised gas or plasma moving at up to 99.9 per cent the speed of light. If that jet points toward Earth, researchers call it a blazar, and it is “one of the most impressive high-energy natural laboratories” in the universe […]

Già, mi ha chiamato “uno dei soggetti,” con effetto comico. Sarà bello e serio lui, magari crede di essere blazzonato perche si chiama blazar (particella di buco nero) - e per quello ci fa sempre vedere dei culi, si sente a casa!

Another target: blazars or marathon gamma ray bursts. Blazars are thought to come from supermassive black holes at the centers of young, active galaxies. “A blazar episode lasts for 10 million to 100 million years,” explains Alan Marscher, an astrophysicist at Boston University who heads the university’s blazar research group. In the process, they generate telltale jets of particles that stretch into space for 10 million to 100 million light-years. Data from GLAST, combined with information from radio-telescopes and visible light, will help scientists tease out the processes behind these galactic beacons.

It’s a paradox of galactic proportions: from the midst of black holes, born of collapsed stars and known for their intense matter- and light-trapping gravity, astronomers have long detected massive jets of hot, ionized gas — known as blazars — shooting out at nearly the speed of light.

The astronomers pointed the telescope at Markarian 501, a galaxy half a billion light-years away that contains a “blazar” — a massive black hole that gives off bursts of gamma rays. Some of the material falling toward the black hole gets squeezed into jets that burst from the poles of the object at close to the speed of light. These jets fire off flares of gamma rays a few minutes long.

Scientists say they have unlocked some of the secrets behind black holes, the gravitational fields known for sucking up light and stars from the Universe. (via BBC NEWS | Science/Nature | Black holes reveal more secrets)

Using almost every type of telescope known to humankind, Prof Marscher believes he has worked out where and how the jets - or blazars - are formed. 
Using an array of 10 powerful radio telescopes, aimed at the galaxy BL Lacertae, the researchers studied a black hole just as it was sending forth a blazar jet.
