Reconstructing 3D magnetic topology of on-disk solar prominence bubbles
Wednesday, 26 May 2021 12:43
Solar prominences or filaments are cool and dense plasma structures suspended in the hot and tenuous corona.
Recent high-resolution solar limb observations reveal that some dark "bubbles" with bright arch-like boundaries form below prominences. It is puzzling that how these bubbles, semi-circular voids, form below dense prominences.
Ph.D. student Guo Yilin from National Astronomical Observatories of Chinese Academy of Sciences (NAOC), together with Dr. Hou Yijun, Dr. Li Ting, and Prof. Zhang Jun, found and investigated an on-disk bubble based on stereoscopic observations for the first time.
The study was published in the Astrophysical Journal Letters.
It is widely accepted that bubbles are closely related to the overlying prominence system and could eventually lead to the generation of a coronal mass ejection. This has serious effect on space weather.
"However, previous studies are all based on the solar limb observations or numerical simulations. If the bubble could be found on the solar disk, we could unveil the magnetic nature of the bubble," said Dr.
Connecting the Dots | The growing market for weather bets

Improvements in satellite weather data collection and analysis are helping financial investors place better bets on the companies they gamble on.
There’s a “huge world” of weather-related investments and financial instruments that investors are increasingly getting to grips with, according to Rei Goffer, co-founder of meteorological intelligence startup Tomorrow.io.
China establishes company to build satellite broadband megaconstellation
Wednesday, 26 May 2021 11:12
HELSINKI — The Chinese government has created a company dedicated to creating and operating a 13,000-satellite broadband constellation.
The State-Owned Assets Supervision and Administration Commission (SASAC), a government body overseeing state-owned enterprises, issued a press release April 29 announcing the creation of the China Satellite Network Group Co.
Europa's interior may be hot enough to fuel seafloor volcanoes
Wednesday, 26 May 2021 11:07
Jupiter's moon Europa has an icy crust covering a vast, global ocean. The rocky layer underneath may be hot enough to melt, leading to undersea volcanoes.
New research and computer modeling show that volcanic activity may have occurred on the seafloor of Jupiter's moon Europa in the recent past—and may still be happening. NASA's upcoming Europa Clipper mission, targeting a 2024 launch, will swoop close to the icy moon and collect measurements that may shed light on the recent findings.
Glittering moon rises ahead of super blood moon
Wednesday, 26 May 2021 10:29
A glittering full moon rose over New Zealand on Wednesday night as people there and around the world waited for a cosmic event known as a super blood moon.
It's when a full lunar eclipse coincides with a supermoon, which is when the moon is particularly close to Earth and appears brighter than normal.
For about 15 minutes, as the moon moves fully into Earth's shadow, the moon will appear to turn red.
EU sees conflict of interest with Eutelsat’s investment in OneWeb
Wednesday, 26 May 2021 10:19
WASHINGTON — Eutelsat’s investment in OneWeb may be incompatible with continued participation in the European Union’s proposed satellite broadband constellation, an EU official warned.
Eutelsat is part of an industry consortium that received a study contract from the European Commission in December 2020 to examine the feasibility of a European satellite constellation to provide secure communications and broadband services, particularly for underserved parts of Europe.
