Scientists think that the solar system formed 4.5 billion years ago from a nebula. This theory is called the Solar Nebular Hypothesis and describes the formation of all matter in our solar system.Answer and Explanation: The solar system is the Sun and the collection of matter that is in its...
Researchers suspected that these are the result of vibrations inside the planet. According to conventional wisdom, Saturn is a uniform fluid ball, a smooth mixture of hydrogen and helium. In theory, this substance can vibrate, forming waves that race around the equator. The undulating gravity of ...
But that's not to say that the moon is doing nothing for us. Take a look at a few things that we would miss if our moon decamped to another neighborhood — or never moved to our 'hood in the first place. Perhaps the most obvious fallout of an absent moon would be the tidal ...

A knowledge of astronomy is essential to understanding the Earth. Astronomers can also use a knowledge of Earth materials, processes and history to understand other planets - even those outside of our own solar system.ADVERTISEMENT The Importance of Earth Science Today we live in a time when ...
That said, the sun hangs around for longer stints at high latitudes — so not everyone inside the circle gets to enjoy a full six months of sunshine. Over in Tromsø, the "Midnight Sun" period goes on for just two months. On Jan. 1, 2011, Arctic communities experienced a rare solar...
This is important. If Jupiter was in this spot, Earth wouldn't be here.这非常重要。如果木星在这个位置，地球就不会在这里了。The discovery, outside our Solar System, of giant planets similar to Jupiter but much closer to their star, posed a serious puzzle for astronomers, because giant ...
This screenshot from the NASA exoplanets website shows the types of planets discovered beyond our Solar System. Image Credit: NASA A team of researchers at Carnegie University and other institutions investigated the effect of extreme pressure and temperature on minerals inside Super-Earths. They perfo...
Our Solar System is believed to have been a nebula of gas and dust that has existed for many millions of years. An event elsewhere caused our nebula to condense into the Sun, the asteroids and planets we know today. Heavier elements would have had to have come from a dying star. ...
