The telescope upgrade reveals the “coronary rain” from Sun with unprecedented details

The outer atmosphere of the sun – the horona – is the hot exterior of our star, and it is usually hidden from view except during the rare overall eclipse. Now, scientists have the clearest appearance at all on this mysterious area, thanks to the new adaptive optics system that is away from blurring the atmosphere, and reveals wonderful views of fake plasma on the star’s surface.

Researchers from the National Institute of Solar Observatory and the New Jersey Institute of Technology revealed the system today, along with wonderful new photos and videos in Sun Corona. Results, Published In astronomy in nature, wonderful structures appear in the solar novel, short -lived plasma jets called Spicules, and even coronary rain: the cooling plasma that dates back to the solar surface along the magnetic field lines of the star.

The team’s invention of the team depends on a technique called coronary adaptive optics. It is installed on the Goode Solar 5.25 feet (1.6 meters) in California, which is the new system-“Cona”-amending a mirror of 2200 times a second to correct the distortions caused by the Earth’s atmosphere. Wonderful technology balance is any potential softening in the telescope, which results in particularly sharp images of aura.

“This technological progress is a changing games,” said Dirk Schmidt, the scientist of adaptive optics in NSO and the main author of the study. Release. “There is a lot to discover when you strengthen your decision with a 10 -worker.”

To date, solar telescopes have used adaptive optics mainly to study the surface of the sun, as mentioned. Corona’s luxurious monitoring was a challenge, as coronary features were unclear on standards of 621 miles (1000 km) – a limit that has existed 80 years ago. But KUNA is now the features to only 39 miles (63 km), the theoretical limit of the Goode telescope.

Among the new shots taken by the team to reshape the twisted solar protrusions in the actual time, spicules fades on the surface, and the hair -like strings of coronary rains are narrower than 12.5 miles (20 km). When you think about the extent of the sun shines from the Earth, the extent of fainting the wreath in relation to the rest of the star, and how much of the turbulent atmosphere of the earth that the team had to cut and correct, the severity of the images is a victory.

“This transformational technology, which is likely to be adopted in observatories all over the world, is preparing to reshape the Earth’s solar astronomy,” said Philip Jude, a physicist in NJit-CTR. “With the operation of coronary adaptive optics now, this represents the beginning of a new era in solar physics, which promises many discoveries in the coming years and decades.”

Notes provide decisive data to detect permanent solar puzzles – such as the reason that Corona is millions of degrees more hot than the solar surface.

The team plans to bring the coronary adaptive optics technology to the solar telescope Daniel K. Inoi in Hawaii-he greatly reveals smaller details of the sun’s atmosphere.
