The general theory about how rocky planets like our own form is pretty well understood, as gas and dust remnant from the process of star formation collapse and stick together to form a rough rock, in the shape of a ball which collides with other such objects to form a planet.Nevertheless, the formation process of gia...
The solar wind represents an emission from the Sun in the form of electrically charged particles, mostly hydrogen, which fills the void space all around the star. Scientists say that these deadly waves of radiation blowing through the whole solar system at speeds as high as 1.6 million kilometers per hour are trigger...
A not so unusual but rather unexpected discovery has been made recently regarding the shock wave generated by the solar wind, as it meets the emissions given off by close-by stars. It seems that the general area of the termination shock through which Voyager 1 and Voyager 2 passed on their way out of the solar system...
The configuration of the solar system as observed today poses some serious questions about how the planets might have evolved from the protoplanetary disk spinning around the Sun, as current models cannot yet explain how a planet the size of Jupiter could have formed in only a few million years, while predictions reg...
Saturn's rings are one of its most distinct features, and although other planets in the solar system present rings of particles, they are not so obvious. They where first predicted to exist in the middle of the 17th century by Christian Huygens and viewed for the first time by Galileo Galilei with his telescope....
The scientific community has been rather excited this week, as the SOHO spacecraft has captured in images what seems to be a small magnetic knot appearing on the surface of the Sun, announcing the end of the 23rd Solar Cycle, which has peaked during 2000 and 2003 with violent solar storms and material ejection. Origi...
This is the first time when astronomers are able to view sun spots and mass ejection due to solar activity, on a star outside the solar system. Having a spin speed rotation about 66 times that of our Sun, the star named 'Speedy Mic' is located about ten million times farther from Earth, than our own star. ...
The past civilizations on Earth mostly regarded the comets as messengers of destruction and rarely as bringers of good or prosperity, while the scientists today think they might have played a key role in the formation of our planet and view them as carriers of possible information about the galaxy, and the formation ...
