Enjoyment of the night sky

Astronomy is one of the oldest sciences. Astronomers of early civilizations performed methodical observations of the night sky, and astronomical artifacts have been found from much earlier periods. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, the making of calendars, and even astrology, but professional astronomy is nowadays often considered to be synonymous with astrophysics.

An international team of astrophysicists has discovered a new planet five times the size of Earth, the smallest extrasolar planet revealed to date outside of our solar system.

Astronomers of early civilizations performed methodical observations of the night sky, and astronomical artifacts have been found from much earlier periods. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Ancient Chinese astronomy is best known today for its observations of comets and supernovas.

Astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena.

Saturn is soo far from the sun that its atmosphere is of course colder than the one of Jupiter. The temperature above the clouds is minus 170 degrees compared to those of Jupiter being minus 120 degrees. The atmosphere is almost similar comprising mainly Hydrogen- Helium and also Methane and Ammonia are present.


Scientists using NASA data are studying a newly recognized type of cosmic explosion called a hybrid gamma-ray burst. As with other gamma-ray bursts, this hybrid blast is likely signaling the birth of a new black hole. It is unclear, however, what kind of object or objects exploded or merged to create the new black hole. The hybrid burst exhibits properties of the two known classes of gamma-ray bursts yet possesses features that remain unexplained.
