Coronal mass ejections (CMEs) are eruptive solar events. They are often associated with solar flares and filaments. CMEs can cause space weather events such as geomagnetic storms, high energy electron storms, hot plasma injection, ionospheric storms, and increased density in the upper atmosphere.

Large CME events can impact communications, navigation systems, aviation activities, and even power grids.

US President Joe Biden will Monday release one of the first images taken by the James Webb Space Telescope, the most powerful observatory ever sent into orbit and a leap forward in uncovering the secrets of the distant universe.

The unveiling will take place at 5:00 pm (2100 GMT) during a livestreamed event at the White House, official statements said, leaving the space community in a state of keen anticipation.

NASA revealed last week Webb's first targets included distant galaxies, bright nebulae and a faraway giant gas planet.

NASA Administrator Bill Nelson recently expressed concerns over China's aims in space, and in particular, that China would, in some way, claim ownership over the moon and stop other countries from exploring it. In an interview with a German newspaper, Nelson cautioned, "We must be very concerned that China is landing on the moon and saying: "It's ours now and you stay out." China immediately denounced the claims as a "lie."

This spat between the administrator of NASA and Chinese government officials comes at a time when both nations are actively working on missions to the moon—and China has not been shy about its lunar aspirations.

In 2019, China became the first country to land a spacecraft on the far side of the moon.
