Be concise, short requires effort but enables faster learning.

Astronoo offers a perilous exercise of writing. Enter your definition of any term having a ratio of near and far with astronomy (cosmos, clusters of galaxies, stars, Sun, Jupiter, orbit or any other word or expression). The only constraint is the length of the text posted. This definition should be in SMS format, i.e. you get away with 160 characters max. You can use SMS language. Submit your definition in the input fields to the right and mail it. The best definitions will be published on this page with the link you want (to be added in the email).

Examples:

Sun: Yellow dwarf star around which eight planets, including our Earth.

Universe: That is all that exists from 13.82 billion years.

Albedo: Ratio between the amount of reflected light and received. The albedo of the basalt is 0.05 and that of the chalk 0.85 or 85%. The maximum reflectivity is 1. www.astronoo.com

 

Aphelion: Away from the Sun. This is the farthest point from the Sun in the orbit of a planet.

Asteroid: Block of stone and metal orbiting between Mars and Jupiter. Ceres is the largest with 770 km in diameter.

Astrobleme: Fossil crater of a collision with an asteroid. Ries crater in Germany, Rochechouart crater in France, Chicxulub in Mexico.

Big Bang: Cosmological theory that explains how the primordial universe, extremely hot and dense, have begun its existence.
www.astronoo.com

 

Van Allen Belt: Area between 700 km and 10 000 km around the magnetic equator. It is the origin of the aurora.

Cosmos: Whole of the particles and the elemental forces in the topology of the dimensions.

 Dark energy: Quintessence or quantum vacuum.

Neutron star: After the explosion of a supernova, the core implodes and stops when the residue has a density of 1 million tonnes per cm3.

Principle of causality: The effect can not precede its cause, it is what makes time is linear and not cyclical.

Anthropic principle: Idea that the universe was set to allow the emergence of an evolved life and consciousness at some point.

Gravitation: For Einstein gravitation is not a force but a deformation of the intimate nature of the space-time.
www.astronoo.com

Perihelion: Near the Sun. This is the closest point to the Sun in the orbit of a planet.
www.astronoo.com

 

Pulsar: Extremely dense dwarf star that rotates on itself so quickly that their light sweeps through space like a lighthouse.
www.astronoo.com

 

Fossil radiation: Microwave radiation, residue of the first moments of the Big Bang that is observed in all directions of the cosmos.
www.astronoo.com

Supernova: Explosive death of a star which have used up its fuel. The explosion can reach the brilliance of 100 million Suns.
www.astronoo.com

 

Black hole: Prison in which the matter is locked up forever. Object so dense that gravity field retains the light.
