Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space-craft-borne instruments of the electromagnetic radiation and high-energy particles emitted by celestial bodies. ...
An astronomer is a scientist who studies celestial bodies such as planets, stars, and galaxies. Historically, astronomy was more concerned with the classification and description of phenomena in the sky, while astrophysics attempted to explain these phenomena and the differences between them using physi...

X RAY ASTRONOMYACTIVE GALACTIC NUCLEIX RAY ASTROPHYSICS FACILITYPOINT SOURCESPLUMESThe X-ray properties of 15 nearby (v < 3000 kms) galaxies that possess AGN and/or starbursts are discussed. Two-thirds have nuclear extended emission on scales from ~0.5 to ~1.5 kpc that is either clearly ...
Physicists can now be automatically alerted to preprints and journal papers in their field, thanks to a new collaboration between two US databases: the arXiv.org preprint server and NASA's Astrophysics Data System ADS). ADS – which contains links to over 4.2 million papers in astronomy, astro...
The energy balance at the top of the atmosphere (TOA) and at the surface of the earth plays an essential role in the Earth’s climate change. The Clouds and Earth Radiant Energy System (CERES) can directly measure the energy radiation at the TOA, while the surface energy balance needs to...
