Are sheet silicates formed deeper in the earth or on the surface? How are they formed ? Halley's Comet appears around the sun about once every 76 years. It passes through the part of its orbit nearest the sun in just a few months but then moves out to great distances and takes more ...
Halley's Comet was officially discovered in 1758, after the death of Edmond Halley, the man credited with its discovery. This is possible because Halley used historical astronomy records to determine that a comet of similar description appeared every 75-76 years. He predicted the comet's return...
A comet leaves a trail of matter behind it as it moves through the inner solar system.Some of this debris may get strewn across Earth's orbit around the Sun.When Earth passes through this part of its annual path, it sweeps through the dust trail.The particles enter Earth's atmosphere at...
These scientists speak of eight probable effects: 1) A disturbed magnetic activity in the sun, producing huge firestorms; 2) That the ionosphere of earth will be changed; 3) That radio and television communications will be disrupted; 4) That there will be weird lighting effects from aurora bo...
Loc:PA, USA, North America, Planet Earth Posted25 June 2022 - 03:58 PM The transparency was variable on Friday night but I was able to view a number of satellite passes, including the Terra satellite and the Tiangong space station, 6 Equulei, Albireo, Alcor-Mizar, Epsilon Lyrae, Omicr...
every 33.2 years. Once assumed to be strictly a 33 year cycle, astronomers came to realize that the debris dispersed irregularly from the cloud that lagged behind the comet. With each successive pass of Tempel-Tuttle, new debris filaments are left in space near older ones. This creates the ...
(i.e. modelling the earth as a plane (don't get any ideas, flat earthers), and the satellite as moving in a straight, parallel line), a satellite will travel in a plane that passes through the observer - a straight line and a point define a single plane. I think that even in ...
If you use an Earth-based telescope to project a laser beam onto the Moon, you can move the spot across the Moon's surface at a velocity greater than the speed of light. Does this violate modern relativity? Halley's Comet app...
Average Velocity: If we want to find the average velocity of an object, we need to divide the displacement of that object by the given period of time. Remember that velocity can be treated as a vector, meaning that it can have a positive or nega...
