Sentences with phrase «many nanoflares»

One suggests the corona is heated via small explosions called nanoflares lower in the atmosphere.

These findings also indicate that nanoflares are powerful, natural particle accelerators despite having energies about a billion times lower than large solar flares.

«These nanoflares, as well as the energetic particles possibly associated with them, are difficult to study because we can't observe them directly,» says Testa.

Those speedy electrons also can be generated by scaled - down versions of flares called nanoflares, which are about a billion times less energetic than regular solar flares.

For example, how frequent are nanoflares?

«Tiny «nanoflares» might heat the Sun's corona.»

«Nanojets and / or nanoflares in the middle corona would be a smoking gun that would explain why the corona is so organized,» DeForest says.

By going off all the time, nanoflares and nanojets could collectively release enough energy to give the corona some structure, simulations have shown.

The shaking from Alfvén waves and the flickers of nanoflares could not only loosen up the tangled skein of magnetism, but also transfer heat high up into the corona.

In April, scientists announced the main reason: small bursts of magnetic energy called nanoflares, which temporarily heat pockets of gas to 20 million degrees.

Scientists had theorized this would cause a nanoflare.

«[These observations] confirm that nanoflares exist and heat at least some of the corona,» says Klimchuk.

Instead, many nanoflares, a million times weaker than traditional solar flares but still packing enough of a punch to meet the United States» energy needs for a year, were acting in concert to heat the corona, the team reports today in Nature Astronomy.

Upcoming FOXSI launches and other space - based telescopes may reveal more about nanoflares, the researchers suggest.

Hoping to build up a more complete picture of nanoflares and their contribution to coronal heating, Glesener is leading a team to launch a third iteration of the FOXSI instrument on a sounding rocket in summer 2018.

But in this case, there was no observable solar flare, meaning the hot material was most likely produced by a series of solar flares so small that they were undetectable from Earth: nanoflares.

In aggregate, these nanoflares could produce enough heat to raise the temperature of the corona to the millions of degrees that we observe.

The NASA - funded FOXSI instrument captured new evidence of small solar flares, called nanoflares, during its December 2014 flight on a suborbital sounding rocket.

There are still questions to be answered, like: How much heat do nanoflares actually release into the corona?

FOXSI's measurements — along with additional X-ray data from the JAXA and NASA Hinode solar observatory — allow the team to say with certainty that the hard X-rays came from a specific region on the Sun that did not have any detectable larger solar flares, leaving nanoflares as the only likely instigator.

One of the consequences of nanoflares would be pockets of superheated plasma.

The core nanoparticle, only 13 nanometers in diameter, enters cells, and the NanoFlare seeks its target.

«The NanoFlare turns on a light in the cancer cells you are looking for,» said Thaxton, an assistant professor of urology at Feinberg.

The NanoFlare technology is the first genetic - based approach that is able to detect live circulating tumor cells out of the complex matrix that is human blood — no easy feat.

A NanoFlare is designed to recognize a specific genetic code snippet associated with a cancer.

Cheng, an assistant professor of medicine in hematology / oncology at Feinberg, provided the cell lines and NanoFlare targets the researchers used to model blood samples taken from breast cancer patients.

If the genetic target is present in the cell, the NanoFlare binds to it and the reporter «flare» is released to produce a fluorescent signal.

The EUNIS spectrograph was tuned into a range of wavelengths useful for spotting material at temperatures of 18 million F, the temperatures that signify nanoflares.

Understanding what and how particles are accelerated out from these smaller nanoflare explosions can help scientists understand what processes create them.

Bradshaw used a sophisticated computational model to demonstrate why spotting signatures of the nanoflares has been so difficult and how the new evidence will help researchers go forward to improve theories on the details of coronal heating - one day allowing heliophysics researchers to at last solve the coronal heating mystery.

Jim Klimchuk, a solar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, explained that the new evidence supports a theory that the sun's corona is heated by tiny explosions called nanoflares.

While the sounding rocket experiments observed the energy produced by these nanoflares, NuSTAR is also able to look for the X-ray signatures of energetic particles.

«The explosions are called nanoflares because they have one - billionth the energy of a regular flare,» said Klimchuk.

The research evidence presented by the panel spotted this super hot solar material, called plasma, representative of a nanoflare.

«We see the evidence of nanoflare heating, but we don't know where they occur,» Caspi said.

Alternatively, micro explosions, termed nanoflares — too small and frequent to detect individually, but with a large collective effect — might release heat into the corona.

In this way, nanoflares may also be the missing link responsible for untangling the chaotic mess of magnetic field lines on the surface of the Sun, explaining why the corona has neat loops and smooth fans of magnetic fields.

Collectively, these nanoflares could account for the corona's million degree temperatures, according to the statement.
