China’s Chang’e 5 moon mission – which successfully returned moon rocks to Earth in December, 2020 for the first time in 44 years – is now headed toward the Earth-sun Lagrange point, for the goal of making sun observations.

What are coronal mass ejections?
Coronal mass ejections – CMEs for short – are powerful eruptions near the surface of the sun that can ripple through our solar system and can interrupt satellites and power grids on Earth. Source: https://earthsky.org/space/what-are-coronal-mass-ejections…
Scientists predicted a large sunspot. Now it’s here
Last week, scientists from the National Solar Observatory predicted a large sunspot would emerge before Thanksgiving. Now the sunspot – AR2786 – is in view. Here’s how they did it. Source: https://earthsky.org/space/nso-predicts-large-sunspot-thanksgiving-nov2020…
The quiet Sun is much more active than we thought: study
Solar activity varies in 11-year cycles. As the activity cycle switches to a new one, the Sun is usually very calm for several years. Source: https://phys.org/news/2020-08-quiet-sun-thought.html…

Spacecraft helps identify solar radiation patterns that expose the moon
Which way the wind blows in space has new importance for astronaut safety at the moon. Using data from several NASA missions, scientists discovered that wind created by high-speed particles from the sun can cause the tail of Earth’s protective magnetic bubble to flap like a windsock in a strong breeze. This movement can pull the tail so far out of…
New ‘sun clock’ quantifies extreme space weather switch on/off
Extreme space weather events can significantly impact systems such as satellites, communications systems, power distribution and aviation. They are driven by solar activity which is known to have an irregular but roughly 11 year cycle. By devising a new, regular ‘sun clock’, researchers have found that the switch on and off of periods of high solar activity is quite sharp, and…
