The Earth from Russia’s Elektro-L satellite

This image compilation, comprised of images taken by the Russian Elektro-L weather satellite, was taken from a geostationary orbit at a distance of 36,000 km. It shows the changing illumination of Earth as it rotated on the autumnal equinox and illustrate the concept of a geostationary orbit. At this height, the satellite is orbiting at fast as the earth is spinning and stays in the same location relative to the surface of earth.

The Lagoon Nebula - M8 in Infrared

The Lagoon Nebula (also known as Messier 8/M8 or NGC 6523) is a giant interstellar cloud and emission nebula located in the constellation Sagittarius approximately 5,000 light-year from earth. The nebula contains a number of Bok globules, which can be seen as dark, collapsing clouds of gaseous material. This Particular image shows a star forming central region in infrared and was captured by the VISTA telescope at ESO’s Paranal Observatory in Chile.

Gliese 832c: is a Potentially Habitable Super-Earth Discovered only 16 Light-Years from Earth

A team of astronomers led by Dr Robert Wittenmyer of the University of New South Wales have discovered the super-Earth. The newly discovered exoplanet, labeled Gliese 832c, has an orbital period of 35.68 days, a mass 5.4 times that of Earth’s and receives about the same average energy as Earth does from the Sun. Gliese 832c might have Earth-like temperatures, giving it a similar terrestrial atmosphere. If the planet has a similar atmosphere to Earth it may be possible for life to survive, although seasonal shifts would be extrem.

Gliese 832c was discovered from its gravitational pull on its star, which causes the star to wobble slightly.

The maximum life span is a theoretical number whose exact value cannot be determined from existing knowledge about an organism; it is often given as a rough estimate based on the longest lived organism of its species known to date. A more meaningful measure is the average life span; this is a statistical concept that is derived by the analysis of mortality data for populations of each species. A related term is the expectation of life. Life expectancy represents the average number of years that a group of persons, all born at the same time, might be expected to live, and it is based on the changing death rate over many past years.

The concept of life span implies that there is an individual whose existence has a definite beginning and end. What constitutes the individual in most cases presents no problem: among organisms that reproduce sexually the individual is a certain amount of living substance capable of maintaining itself alive and endowed with hereditary features that are in some measure unique. In some organisms, however, extensive and apparently indefinite growth takes place and reproduction may occur by division of a single parent organism, as in many protists, including bacteria, algae, and protozoans. In order to consider life span in such organisms, the individual must be defined arbitrarily since the organisms are continually dividing. In a strict sense, the life spans in such instances are not comparable to those forms that are sexually produced.

There is a brief period during which it is impossible to say whether an organism is still alive, but this time is so short relative to the total length of life that it creates no great problem in determining life span.

Some organisms seem to be potentially immortal. Unless an accident puts an end to life, they appear to be fully capable of surviving indefinitely. This faculty has been attributed to certain fishes and reptiles, which appear to be capable of unlimited growth. Without examining the various causes of death in detail, a distinction can be made between death as a result of internal changes (i.e., aging) and death as a result of some purely external factor, such as an accident. It is notable that the absence of aging processes is correlated with the absence of individuality. In other words, organisms in which the individual is difficult to define, as in colonial forms, appear not to age.
