Short definition: 

Tektites are small pieces of natural glass that are typically black, green, brown, or grey in color. They are created when meteorites impact the Earth and cause terrestrial debris to be ejected and melted into a glass-like material.

Detailed Definition:

A tektite is a type of glass that is formed from the impact of a meteorite on the Earth's surface. The extreme heat and pressure of the impact melts and vaporizes the rocks at the impact site, which then cools and solidifies into a glass-like material. Tektites are typically black or green in color and have a smooth, rounded shape. They can vary in size from a few millimeters to several centimeters in diameter. Tektites are found in the areas around meteorite impact craters, and are used by scientists to study the effects of meteorite impacts on the Earth's surface.

Etymology:

tēktós - molten

Sample Sentence(s):

"Sir Thomas Mitchell found a tektite and gave it to Charles Darwin."

"Some human built objects, such as black buttons, can be mistaken for tektites."

Short Definition:
The Kuiper belt (called Edgeworth-Kuiper belt) is a region in space located in the outer Solar System placed between 30 to 50-55 AU (astronomical units) from the Sun. It is a doughnut-shaped ring composed of gas, dust or asteroids.

Detailed Definition:
The first hypotheses about the Kuiper belt appeared in 1930, but it took over 50 years to confirm that hypotheses. Since then scientists discovered over 100000 KBOs (Kuiper belt object) with the diameter larger than 100 km. With that distance from the Sun, objects are mostly composed of leftovers from the solar system's early history which means icy bodies (frozen chemical elements and compounds). The largest KBOs are: Pluto (composed in 98 percent from nitrogen ice) and Eris (mostly built from methane). As the Kuiper Belt is icy-cold place it is thought to be the source of the comets in the solar system. The fascinating thing is that not only planets and dwarf planets might have moons but also lots on Kuiper Belt objects have ones.

Etymology:

Kuiper – Dutch – Kuiper - cooper – from the name of the scientist Gerard Kuiper
Belt – Latin - balteus - girdle

Sample Sentence(s):
“The amount of material in the Kuiper Belt today might be just a small fraction of what was originally there.”

French:
Ceinture de Kuiper

German:
Kuipergürtel

Polish:

Short Definition:
Solar system is the planetary system consisting of the Sun and other celestial objects which are gravitationally bounded with the Sun, located in an outer spiral arm of the Milky Way galaxy.

Detailed Definition:
The Solar system formed 4.6 billion years ago from the solar nebula. The mass of the Solar system is unevenly distributed. The Sun weights 99,86 % of the all masses in the system. The rest of it falls on the planets, dwarf planets, moons, asteroids etc. The Solar System is divided into 2 parts: the Inner Solar System (Mercury, Venus, Earth, Mars) – terrestrial planets composed of rock and metal and Outer Solar System (Jupiter, Saturn, Uranus, Neptune) – giant planets. The first two are gas giants (composed of hydrogen and helium), and the next two are ice giants (composed of water, ammonia, and methane). Between the inner and outer system is an asteroid belt with Ceres (dwarf planet). It is assumed that the asteroid belt has been created in a collision of a planet and celestial object. Behind the Neptune there is a Kuiper belt – similar to asteroid belt with Pluto, Charon and Eris (dwarf planets).

Etymology:
solar – Latin – solis - Sun
system – Greek – systema - set of entities that interact in an orderly and organized fashion

Sample Sentence(s):
The solar wind emanating from the Sun blasts through the Solar System, interacting with the planets, and pushing material out into interstellar space.

Système solaire

German:
Sonnensystem

Solsystem

Definition:

A study aiming to investigate the effects of spaceflight on the human organism. The study was organized by NASA with the support of 8 universities across the USA. It was conducted in 2015-2016 and involved two identical twin brothers: Scott and Mark Kelly.

Scott Kelly served on a year-long mission aboard the International Space Station, while his brother Mark Kelly, a former NASA employee, remained on Earth. The twins study included an array of biochemical, neurological and other types of medical tests conducted before, during and after the spaceflight, i.e. over the span of 27 months. The results confirmed the robustness and resilience of human health, since 91,3% of Scott Kelly’s medical parameters returned to baseline six months after the spaceflight. The remaining changes were to be used for development of personalized measures to predict and overcome possible adverse consequences of spaceflight.
