Illustration of an emission of a gamma ray ( γ ) from an atomic nucleus Source: https://en.wikipedia.org/wiki/Gamma_ray#/media/File:Gamma_Decay.svg

Short Definition:

Gamma rays are very high frequency electromagnetic radiation emitted as an outcome of radioactivity. Due to high frequency, gamma rays have very high energy. Natural sources of gamma emission originating on Earth are mainly an effect of radioactive decay and secondary radiation from atmospheric interactions among cosmic ray particles.

Detailed Definition:

A gamma ray, also known as gamma radiation, is a penetrating form of electromagnetic radiation originating from the radioactive decay of atomic nuclei. Gamma rays from radioactive decay are within the energy range starting at few kiloelectronvolts (keV) to roughly 8 megaelectronvolts (MeV), matching to the usual energy levels in nuclei among reasonably long lifetimes. The energy spectrum of gamma emission can be utilized to recognize the decaying radionuclides with a technique called gamma spectroscopy. Very-high-energy gamma rays in the 100–1000 teraelectronvolt (TeV) range have been observed from sources such as the Cygnus X-3 microquasar.

Etymology:

gamma - The third letter of the Greek alphabet (Γ, γ),
radiation - From the past participle stem of Latin radiare (“to gleam, shine, beam”).

Sample Sentence(s):

"Solar flares emit across the entire electromagnetic spectrum, including gamma rays."
"Gamma rays originating from far-distant quasars are used to estimate the extragalactic background light in the universe."

Projection of the path traced by geosynchronous satellites of different inclinations. Source: Wikipedia

Short Definition:
Geosynchronous orbit is an orbit with orbital period matching Earth's full rotation time.

Detailed Definition:
Objects in geosynchronous orbit appear to trace out a path on the sky, typically a figure-8 shape every day. The exact path depends on orbit's eccentricity and inclination, but the object can be observed in the same place on the sky, same time every day. This type of orbit is useful for example for Earth observing satellites.

Etymology:
From ancient greek geo (Earth) + synchronous

Sample Sentence(s):
A satellite is placed in geosynchronous orbit above Europe.

Short Definition:

Gravity assistance describes the intentional use of the gravitational attraction of a celestial body, in order to modify the trajectory of a space vehicle. This maneuver allows the spacecraft to save rocket fuel.

Detailed Definition:

Etymology:

1. Gravity (Noun.), originating from the Latin word gravitatem, with the meaning of “weight, heaviness, pressure”

2. Assist (Verb.), originating from Latin word assistere, which means “standing by, help”

Sample Sentence(s):

“The global minimum velocity increments of direct transfer trajectory and gravity-assist trajectories are obtained for each candidate target.”

As of 2021, the Great Red Spot is reported to be about 10,000 miles across and 300 miles deep into the atmosphere of Jupiter. However, according to NASA observations, it is shrinking and becoming taller, and it is not yet clear whether the Great Red Spot will stabilize or disappear completely.

Short Definition:

Heavy elements are the general name for elements containing atomic numbers greater than 92. Above these, elements with atomic numbers 112 and above are called superheavy elements. The state that creates the atomic number is the number of protons in the nucleus of the element.

Detailed Definition:

Heavy elements, which are determined by the number of protons in the nucleus of the element (this called atomic number) are elements with atomic number greater than 92. One row above them there is superheavy elements with atomic numbers greater than 112. The first artificially produced heavy and superheavy elements were first produced during the Cyclotron experiments.

One of the most important issues about heavy elements is the concept of 'island of stability'. This concept refers to the region in the table of nucleides where elements with half-lives longer than some other super heavy elements are found. However, it should be noted that we are ona narrow time scale, from minutes to micro/nano seconds at most. The term was first coined in 1998 with the discovery of the super heavy element 114 (Flerovium).

Etymology:

Heavy – From Proto Germanic (hafiga)

Element – From Latin (elementum)

Short Definition
Hubble Space Telescope is a large telescope used to observe distant space objects. Hubble can observe almost complete light spectrum from the ultraviolet to near infrared light allowing extensive research of space. Its research includes but is not limited to beginning of the Universe, black holes, exoplanets and nebulas.

Detailed Definition
Hubble is a Cassegrain mirror telescope. It is built with two hyperbolically curved mirrors that are positioned facing each other. The main mirror that accumulates the light from celestial bodies is curved inwardly and leads light to the secondary smaller mirror. Second mirror is curved outwardly and diffuses the light bouncing it back to the first mirror. At the main mirror the light is finally collected together and lead to the focal point where optical instruments can gather the data.

Hubble was launched in 1990 and has been visited multiple times between 1993 and 2009 by astronauts. Those missions included various repairs like correcting mistakes that were noticed first after we started collecting the data and adding new science instruments to make information analysis easier.

Hubble studies helped us understand our Universe better being the first telescope located outside of Earth's atmosphere that prevented us from research of ultraviolet light that is only visible in space. One of the most important discoveries that Hubble made include:
-More accurate estimate on age of the Universe,
-Determining the rate with which the Universe is expanding,
-Discovering that almost every big Galaxy has a black hole at its center.

Etymology
Hubble Space Telescope is named after Edwin Powell Hubble, who made one of the most important discoveries in the field of astronomy in the 20th century.

Sample Sentence(s):

Hubble Space Telescope helped researchers make new discoveries.

Astronomers around the world use Hubble Space Telescope to research new exoplanets.

Short Definition:

A usually massive iron-black mineral that consists of an oxide of iron and titanium and that is a major titanium ore.

Detailed Definition:

Ilmenite is named after the Ilmenski mountains in Russia, where the mineral was first discovered. It is slightly magnetic, which means that magnets can be used to separate it from other minerals in sand deposits. Ilmenite is also a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. Also, it is a black iron-titanium oxide with a chemical composition of FeTiO3. 

Etymology:

Named after Ilmen Mountains in Russia +‎ -ite in 1827. 

The suffix –ite is used to form nouns denoting rocks or minerals, from Latin -ītēs, and from Ancient Greek -ῑ́της.

Sample Sentences:

"Ilmenite is an economically important and interesting mineral."

"Ilmenite is the most important ore of titanium and the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics."
