Definition:

Rapid expansion of the universe at its early stages of development (at around 10-36 seconds after the Big Bang).

The Inflation Theory was developed in 1980 by Alan Guth, Andrei Linde, Paul Steinhardt, and Andy Albrecht and attempted to account for phenomena that could not be explained by the Big Bang Theory (the Horizon Problem, the Flatness Problem and the Monopole Problem). Nowadays, the Inflation Theory is considered to be an extension of the Big Bang Theory.

Short Definition:

Light with wavelength from 800 nanometers to 1 millimiter.

Detailed Definition:

Electromagnetic radiation with wavelengths ranging from 800 nanometers to one millimeter. It is next to the red end of the visible spectrum, hereby the name. Also called IR, it is a kind of electromagnetic radiation that has qualities like both a wave and a particle, the photon, and propagates energy and momentum as well as exerting radiation pressure.

Etymology:

Infrared comes from Latin: infra, which means below.

Sample Sentence(s):

To keep an eye on workplace activities, they used infrared cameras.

Without disturbing the bats, an infrared camera records them.

Image source: https://upload.wikimedia.org/wikipedia/commons/thumb/d/d5/Plot_of_various_initial_mass_functions.svg/800px-Plot_of_various_initial_mass_functions.svg.png


Short Definition:

The initial mass function (IMF) describes the distribution of stellar masses as a large cluster of stars is newly formed and is based on an average from stars in our Milky Way.

This function is useful for understanding the formation of stellar systems and their evolution. In most cases, the initial mass function is shown with a logarithmic scale.

Derailed Definition:

The initial mass function shows few massive stars which are more massive than the sun, while sun-sized stars are more abundant and stars that are smaller than the sun are quite common (this trend does not continue linear the smaller they get):

The function can be described by using the following law:

IMF = constant x m^(-α)

where m = initial star mass and α = slope of the logarithmic plot.

Until this point in time, it is not certain if the IMF varies in extreme situations and if the calculation based on our Milky Way can be unconditionally applied to other galaxies.


Etymology:

initial - Latin initialis ("initial, incipent, of the beginning")

mass - old French masse (" lump, heap, pile; crowd, large amount")

function - Latin functionem (" a performance, an execution")


Sample sentences:

There are different curve forms of the initial mass function based on the way the alpha and the constant are calculated.


Translation:

French: fonction de masse initiale

German: Anfangsmassenfunktion

Polish: początkowa funkcja masy

Swedish: funktion för dem ursprungliga massan

Short Definition:

The interstellar medium (ISM) is a composition of radiation and matter which occurs between star systems, which are compositions of stars orbiting each other. The medium is usually created from various gasses, mostly hydrogen and helium. This matter is a filler between the stars.

Detailed Definition:

The interstellar medium (ISM) is a region filled with gas and dust in between stars. The medium is created when a star dies. As the star collapses into itself, it releases huge amounts of energy and matter at high velocity and high temperature. When this mix encounters patches of interstellar gas, the visible nebulas of interstellar medium are created. The gas is ionized, and space dust blocks certain light waves which. Contrary to common belief, space is not completely empty and is not a full vacuum but is filled with matter such as gas and space dust. The interstellar medium is impactful in formations it is in. Stars which are positioned in the denser areas of ISM supply it with matter and energy through stellar winds or supernovae (the explosion of a star). The inter-influence of stars and ISM formations helps scientists determine the lifespan of given star formations.

Etymology:

This phrase is a conjunction between the words 'interstellar' and 'medium'. The word 'interstellar' comes from combining the prefix 'inter' from Latin for "between" and the word 'stellar' from Latin 'stellaris' meaning "pertaining to a star". The word 'medium' from Latin medium "the middle, midst, center; interval"

Sample Sentence(s):

1. The interstellar medium can be visible with long exposure astrological photography.
2. The Pillars of Creation are a beautiful example of the interstellar medium.

James Webb Space Telescope

(Last edited: Saturday, 30 September 2023, 9:51 PM)

Source:

Short Definition:

The James Webb Space Telescope is a large telescope in space that conducts infrared astronomy. The cutting edge telescope technology aims to shine light on stars or galaxies, that were previously hidden in “plain” sight. Many people think this is the successor to the Hubble telescope, but in reality, it is more of a successor for the Spitzer space telescope, which also is an infrared telescope. The property of light to shift to red makes this a helpful telescope to look at the oldest galaxies.

Detailed Definition:

The James Webb Space Telescope is a visualizing device for away structures or phenomenons that work in the infrared range. The biggest telescope in space had to overcome many difficulties to even be transported to space. The telescope had to be folded to even fit in the rocket, and so they used Origami techniques to transport it safely to its place. JWST is not an all-rounder telescope like Hubble is. JWST aims to discover secrets from almost the beginning of time with the most sophisticated infrared sensors, cameras and lenses that were used till now, but looking at the oldest stars and galaxies is not its only job. JWST will also be used to identify fitting exoplanets by scanning the atmospheres of those planets for the right gas composition.

Etymology:

Latin- spatiumà Old French -espaceà Middle English – space

Modern latintele and modern latin -scopiumà Modern latin – Telescopiumà English telescope

Sample Sentence(s):

Webb will be the largest telescope ever placed in space; 100 times more powerful than Hubble. So big it has to fold origami-style to fit in the rocket and will unfold like a "Transformer" in space (NASA)

 NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from NASA’s James Webb Space Telescope. (NASA)

Definition: 

Kalpana Chawla, born in Karnal, India, in 1962, is first astronaut with an Indian descent. In her early years, her father took her to local flying clubs, where she developed her passion for flying. She moved to the U.S. to pursue degrees in engineering (Ph.D. in aerospace engineering from the University of Colorado) and eventually after graduation, she did research, focusing on vertical take-off and landing concepts. Her area was the development and implementation of efficient techniques for performing aerodynamic optimization. In 1994, Chawla was chosen as an astronaut candidate and took part in 2 space flights. The second flight ended tragically in 16.01.2003, as Space Shuttle Columbia exploded while being on the way back to the Earth, after 15 days and 22 hours spent in space. The explosion while re-entrng into Earth's atmosphere killed all seven astronauts on board, including Kalpana Chawla.
