On the correlation and interactions of space weather with biological indicators

On the correlation and interactions of space weather with biological indicators

1. Introduction Space weather is significantly affected by geomagnetic disturbances (GMDs) that occur during or after intense solar events such as coronal mass ejections (CMEs), which expel substantial amounts of electromagnetic particles into interplanetary space. Most of these particles collide with the magnetosphere (the outermost region of the atmosphere) where the solar wind (continuous flow …[Read More]

The 2017 solar eclipse and scientific discoveries

The 2017 solar eclipse and scientific discoveries

The next solar eclipse is upon us. On August 21 the moon will pass between the Sun and an observer’s point of view in America and block out daylight, creating an eerie gloom in the sky. The transit of the moon between the Earth and Sun occurs about every 18 months, but for your particular city it …[Read More]

Capturing a Whole Total Eclipse of the Sun: Megamovie

Capturing a Whole Total Eclipse of the Sun: Megamovie

by Hugh S Hudson (U. of Glasgow and UC Berkeley) Normally solar eclipses give an observer only a fleeting moment (minutes at most) to enjoy the solar corona. We aim to amplify that considerably in the August 21 eclipse across North America. The plan is simple: Megamovie will capture everybody’s images, especially those from a …[Read More]
