New images of the sun's chromosphere—the lower region of the solar atmosphere—have been released, and to say they are "stellar" is an understatement. Simply, they are stunning. The high-resolution images were taken with ...
Following the termination of the flight of the balloon-borne solar observatory Sunrise III on July 10, team members have reached the landing site and found the observatory's science payload largely intact. According to current ...
Approximately a month before it begins its research flight in the stratosphere, the balloon-borne solar observatory Sunrise III has looked at the Sun for the first time from its launch site at the Arctic Circle. In June, ...
Using the MeerKAT radio telescope, an international team of astronomers have detected radio flares on a nearby M dwarf star known as SCR 1746−3214. The finding, reported in a paper published April 7 on the pre-print server ...
Solar transition region supersonic downflows (SDs) are downward falling mass flux toward the sunspots. This phenomenon commonly exists above most sunspots. In IRIS spectra, SDs are often observed as strongly redshifted secondary ...
Solar Orbiter's latest images shows the full sun in unprecedented detail. They were taken on 7 March, when the spacecraft was crossing directly between the Earth and sun.
The number of sunspots on our sun typically ebbs and flows in a predictable 11-year cycle, but one unusual 70-year period when sunspots were incredibly rare has mystified scientists for 300 years. Now, a nearby sun-like star ...
Scientists have unraveled the science behind the jets of plasma—the fourth state of matter consisting of electrically charged particles that occur just about everywhere in the sun's chromosphere, which is the atmospheric ...
A joint research team has found the formation of magnetic islands with the twisted structure in the current sheet during the fast magnetic reconnection for the first time.
In a study published in Astronomy & Astrophysics, Prof. Xing Lifeng from Yunnan Observatories of the Chinese Academy of Sciences and his collaborators found the chromospheric activity index of a sample active stars increases ...
