Earth’s magnetic field reverberated from a Coronal Mass Ejection (CME) impact during the early hours of Jan. 22nd. The hit compressed Earth’s magnetic field, briefly exposing some geosynchronous satellites to solar wind plasma, and disturbed the ionization structure of Earth’s upper atmosphere.
As night fell on Jan. 22nd, Arctic sky …

Active sunspot 1401 erupted yesterday, Jan. 19th, for more than an hour around 16:00 UT.
The long-duration blast produced an M3-class solar flare and a Coronal Mass Ejection that appears to be heading toward Earth.
Forecasters say strong geomagnetic storms are possible when the cloud arrives during the late hours …

In 1995, the Hubble Space Telescope‘s ‘Pillars of Creation’ image of the Eagle Nebula became one of the most iconic images of the 20th century. Now, two of ESA’s orbiting observatories have shed new light on this enigmatic star-forming region.
Combining almost opposite ends of the electromagnetic spectrum, this …
