The fact that we have total solar eclipses is ultimately just a cosmic coincidence. It just so happens that the moon appears to be the same size as the sun from our position on the surface of the planet Earth. There are no other planets and moons in the solar system where this occurs....
It's all the result of a freakish cosmic coincidence, when the moon and sun appear to be the exact same size in the sky. "The sun is 400 times bigger than the moon," said Ting. "But by happy coincidence, it is also 400 times further away. So, from our perspective they are the ...
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. The solar system stretches outward from the sun, passing the four inner planets, thro...
North America is on the verge of another masking of the sun during a total solar eclipse. This one will last almost twice as long, with an even wider audience, than the eclipse that stretched coast-to-coast in 2017.
A total solar eclipse is happening in North America this Monday (April 8) when the moon travels between the sun and the earth, and for a brief moment, entirely blocks the sun from our perspective. This is a rare celestial phenomenon, with the next one in North America predicted to occur...
solar eclipseionospheretotal electron contentA reliable interpretation of solar eclipse effects on the geospace environment, and on the ionosphere in particular, necessitates a careful consideration of the soヽalled eclipse geometry. A solar eclipse is a relatively rare astronomical phenomenon, which ...
Clouds can often be a pretty inconsequential part of a weather forecast from the public’s perspective, compared to temperature and precipitation. But on Monday, cloud cover could be what stands – or floats –between the solar eclipse and throngs gathered along the path of totality i...
tidal forces within Io that cause its intense volcanism. What wasn't clear until now was just how long the influence of Jupiter and its moons had been wreaking havoc on Io. That's because the constant flow of lava from the extreme volcanism across its surface keeps this moon looking fresh...
