Astronomers had witnessed this kind of cosmic event before. Similar scars had been left behind during the course of a week in July 1994, when more than 20 pieces of Comet P/Shoemaker-Levy 9 (SL9) plunged into Jupiter's atmosphere. The 2009 impact occurred during the same week, 15 years later.

Backwards Black Holes Might Make Bigger Jets

This artist’s concept shows a galaxy with a supermassive black hole at its core. The black hole is shooting out jets of radio waves. Image credit: NASA/ JPL- Caltech.
"A lot of what happens in an entire galaxy depends on what's going on in the miniscule central region where the black hole lies," said theoretical astrophysicist David Garofalo of NASA's Jet Propulsion Laboratory in

Breve Historia de la Astrofísica
La astrofísica nace con la observación, realizada a comienzos del siglo XIX por J. von Fraunhofer (1787-1826) de que la luz del Sol, atravesando un espectroscopio (aparato capaz de descomponer la luz en sus colores fundamentales), da lugar a un espectro continuo sobre el cual se sobreimprimen líneas verticales, que son la huella de algunos de los elementos químicos presentes en la atmósfera solar, por ejemplo el hidrógeno y el sodio. Este descubrimiento introdujo un nuevo método de análisis indirecto, que permite conocer la constitución química de las estrellas lejanas y clasificarlas.
Astrophysics
Part of Astronomy that study physical and chemical characteristics of heavenly bodies. Astrophysics is the most important part of Astronomy at the present time owing to advance of modern physics. Doppler- Fizeau´s effect, Zeeman´s effect, quantum theories and thermonuclear reactions applied to study of heavenly bodies have permitted to discover the solar magnetic field, study stellar radiations and their processes of nuclear fusion, and determine radial velocity of stars, etc. Electromagnetic radiation of heavenly bodies permits to make spectrum analysis of themselves, and they are the principal fountain of information in this part of Astronomy.
