(ITALY) JUST IN: Nature Journal Report: In landmark research published Wednesday scientists reported that they’ve made the first detection of almost-ethereal particles called neutrinos that can be traced to carbon-nitrogen-oxygen fusion, known as the CNO cycle, inside the sun #AceNewsDesk report

#AceNewsReport – Dec.04: It’s a landmark finding that confirms theoretical predictions from the 1930s, and it’s being hailed as one of the greatest discoveries in physics of the new millenium. “It’s really a breakthrough for solar and stellar physics,” said Gioacchino Ranucci of the Italian National Institute for Nuclear Physics (INFN), one of the researchers on the project since it began in 1990:

The scientists used the ultrasensitive Borexino detector at the INFN’s Gran Sasso particle physics laboratory in central Italy — the largest underground research center in the world, deep beneath the Apennine Mountains, about 65 miles northeast of Rome.

The detection caps off decades of study of the sun’s neutrinos by the Borexino project, and reveals for the first time the main nuclear reaction that most stars use to fuse hydrogen into helium… Scientists calculate that the CNO cycle is the primary type of fusion in the universe. But it’s hard to spot inside our relatively cool sun, where it accounts for only 1 percent of its energy… Ranucci said the Borexino detector has spent decades measuring neutrinos from the sun’s main proton-proton chain reaction, but detecting its CNO neutrinos has been very difficult — only about seven neutrinos with the tell-tale energy of the CNO cycle are spotted in a day:

The discovery required making the detector ever more sensitive over the last five years, Ranucci said, by shielding it from outside sources of radioactivity so that the inner chamber of the detector is the most radiation-free place on Earth.

#BREAKING144 Philae comet lander wakes up, says European Space Agency

#AceBreakingNews – June.14: The European Space Agency (Esa) says its comet lander, Philae, has woken up and contacted Earth.

Philae, the first spacecraft to land on a comet, was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November.
It worked for 60 hours before its solar-powered battery ran flat.

The comet has since moved nearer to the Sun and Philae has enough power to work again, says the BBC’s science correspondent Jonathan Amos.

An account linked to the probe tweeted the message, “Hello Earth! Can you hear me?”

On its blog, Esa said Philae had contacted Earth, via Rosetta, for 85 seconds on Saturday in the first contact since going into hibernation in November.

“Philae is doing very well. It has an operating temperature of -35C and has 24 watts available,” said Philae project manager Stephan Ulamec.

Scientists say they now waiting for the next contact.

‘Comet hitchhiker’

ESA scientist Mark McCaughrean told the BBC: “It’s been a long seven months, and to be quite honest we weren’t sure it would happen – there are a lot of very happy people around Europe at the moment.”

Philae was carrying large amounts of data that scientists hoped to download once they made contact again, he said.

“I think we’re optimistic now that it’s awake that we’ll have several months of scientific data to pore over,” he added.

This is one of the most astonishing moments in space exploration and the grins on the faces of the scientists and engineers are totally justified, says BBC science editor David Shukman.
