Explain the process that is responsible for the energy in the sun. Briefly (in a few sentences at most) describe the fundamental interactions between solar radiation and the Earths' atmosphere. What happens to the energy absorbed...
During a solar eclipse, when sunlight is blocked momentarily from reaching Earth, the loss of this light energy is tangible; visit oureclipse pageto view upcoming dates and discover how a brief loss of sunlight can affect everything from the sky's appearance to weather patterns! How Light Inte...
"My feeling is — if the sun sneezes, Earth catches a cold, because we always feel the impact of what happens on the sun thanks to the solar wind," said Nicky Fox, the division director for heliophysics at NASA Headquarters in aNASA Science article. On Earth, the solar wind is responsib...
Those kinds of crazy wild swings in the axial tilt are due to resonances, or unlucky interactions with distant objects in the solar system. For instance, letꞌs say that one day in its orbit the Earth's axis just happens to point away from the sun, and Jupiter is hanging out in that...
a whopping 24.3 billion kilometres out to the furthest reaches of our solar system. It is remarkable, then, that when it comes to our own home, we have literally only scratched the surface – the deepest hole ever dug reached less than 1% of the distance to the centre of the Earth. ...
In a few billion years, this wobble could even cause the innermost planet to collide with the sun or a planet. Frame-dragging of space-time around rotating bodies The spin of a heavy object, such as Earth, should twist and distort the space-time around it. In 2004, NASA launched the ...

Its climax is centered on January 16, 2025, the day of the solar opposition to Mars at 26° 12' Cancer - the biennial Mars perigee (closest approach to Earth). We've all seen it in the news of the day lately - the fires, crashes, clashes and explosions blowing through the world ...
This lowers the angle and amount of solar radiation that reaches the earth’s surface. This tilt also produces a large temperature differences, as the rate of cooling is higher in the polar region compared to the equator. This difference powers the jet stream that produces massive winter storms...
The solar lighting system transforms solar energy into electrical energy that is subsequently converted into light energy. Solar energy is captured by solar panels using semiconductor materials. These materials convert their light energy into electrical energy (generating free ...
