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 planets of that kind cannot form in such zones. Planets form in a disc of gas and dust that surrounds the young star.在我们的...
Exploring the former lakes of Mars, these scientists are hoping to answer one of the major questions of astronomy and biology. Is life a pretty ordinary phenomenon in the universe, popping up wherever conditions are favourable, or is it really a one-off phenomenon that we have practically no ...

It is crucial to realize that an "observatory" is more than simply a telescope or ensemble of telescopes that provide observing opportunities for astronomers. Observatories are at the heart of an institutional capability to do things beyond what is possible for astronomers themselves to do as ...
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 the Earth and its inhabitants face many challenges. Our climate is ...
(Of course, division would then play the role of vector subtraction.) To avoid confusion, one might refer to as a log-vector space rather than a vector space to emphasize the fact that the vector structure is coming from multiplication (and exponentiation) rather than addition (and ...
