AI Thread Summary
A geomagnetic storm is a temporary disturbance of Earth's magnetosphere caused by solar activity, specifically when solar wind interacts with Earth's magnetic field. This phenomenon is a significant aspect of space weather and can lead to effects such as the aurora borealis. The recent discussion referenced a geomagnetic storm linked to a coronal mass ejection that occurred on January 24. It's important to clarify that geomagnetic storms are caused by solar activity, not the other way around. Understanding these storms is crucial for comprehending their impact on Earth and space weather.

can somebody explain to me what is geomagnetic that recently run down to earth?
i really want to know.
 
Astronomy news on Phys.org
I'm sorry, what are you referring to? I've never heard of a geomagnetic.
 
i'm really sorry if i got it wrong. but, i just want to know about something at the space that fall to earth, and produce solar storm.i don't really know what it is.
 
Maybe he is referring to the geomagnetic storm that was caused by a solar coronal mass ejection and caused the aurora borealis on January 24?
 
Here is an excerpt from an article that explains it in detail.

Geomagnetic storm
A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by a disturbance in the interplanetary medium. A geomagnetic storm is a major component of space weather and provides the input for many other components of space weather. A geomagnetic storm is caused by a solar wind shock wave and/or cloud of magnetic field which interacts with the Earth's magnetic field.

Timacho, please note that the geomagnetic storm does not produce a solar storm. Quite the opposite. The geomagnetic storm itself is caused by solar activity. It is
called "geomagnetic" [geo=earth] because it is triggered when the solar wind interacts with Earth's magnetic field.

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
