"Contrary to what one might expect, such proximity does not necessarily mean that Proxima b's surface is too hot" for water to exist in liquid form, said a CNRS statement. The particles follow spiral trajectories around the direction of the magnetic field of the planet. (more…)...

Galileo was forced to disavow his work, and was sentenced to house arrest for the remainder of of his life. Some forms of radiation, such as infrared, reach Earth’s surface only at locations such as mountaintops, where the air is thin, or deserts, where humidity is low. This note covers the following topics: Drake Equation, Influence of the Sun on Earth, Why the Sun Shines, Lives of the Stars,...

Students completed the “If We Had No Moon” worksheet that accompanied the video during class today and all worksheets were due at the end of the class period. But observations taken at longer sub-millimetre wavelengths in 2004, by the Submillimeter Array in Hawaii, revealed fuzzy, knotty structures that may be blobs launched 400 years ago, the researchers said. In neutrino astronomy, astronomers use heavily shielded underground facilities such as SAGE, GALLEX, and Kamioka II/III for the detection...

A comet nucleus is about the size of a mountain on earth. Astronomy is the scientific study of the universe as a whole, and of celestial bodies and the underlying physics governing those bodies. The telescope's optical surfaces, in particular, would have to survive all this while staying aligned to a precision of nanometres. It gives information on easy to spot constellations, the Moon phases and contains a Planet watch. (more…)...
