Einstein ring

(Last edited: Monday, 13 March 2023, 3:51 PM)



Definition

A ring-shaped distortion of light from a galaxy caused by gravitational lensing, while this galaxy passes behind another massive object.

It is sometimes also referred to as the Chwolson ring, named after a Soviet scientist Orest Chwolson, who mentioned this phenomenon in his article (in English, his surname is usually transcribed as Khvolson, however, German transliteration Chwolson is used instead, since his article was first published in a German academic journal).


Etymology

The phenomenon is named after Albert Einstein, who predicted it in his theory of general relativity.


Translation:
  • French: anneau d'Einstein
  • German: Einsteinring [ˈaɪ̯nʃtaɪ̯nˈʁɪŋ]
  • Polish: pierścień Einsteina

European Space Agency is an intergovernmental organisation, whose mission is to develop space capabilities through exploration for the benefit of citizens of Europe and the whole world.

European Space Agency was established in 1975 and  is dedicated to the peaceful exploration of space. It comprises of 22 Member States, who work together to find out more about the Earth and space, but it also cooperates closely with other organisations outside of Europe, for example with NASA. The aim is to develop research, coordinate space programmes and to promote mutual agreements between the members. It is funded by membership donations calculated based on each country’s gross national product.

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.”


Translations:
  • French: Assistance gravitationnelle
  • German: Schwerkraftumlenkung
  • Polish: Asysta grawitacyjna
  • Swedish: Gravitationsslunga

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.

The Solar System

(Last edited: Friday, 28 April 2023, 6:09 PM)


Image Source:

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.

Event Horizon

(Last edited: Friday, 28 April 2023, 6:09 PM)


Source(s):


Short Definition:

The event horizon of a black hole is a threshold around the black hole where the escape velocity surpasses the speed of light. It is also referred to as a boundary beyond which events cannot affect an observer.

Detailed Definition:

The term event horizon is used to describe the phenomena of a very strong gravitational pull in the vicinity of a massive and compact object, which is able to prevent even light from escaping. The escape velocity is a threshold value for which the event horizon occurs. It is the velocity needed for an object to overcome the forces acting due to the presence of an enormous mass. If it is greater than the speed of light, it is impossible to witness any event taking place past the event horizon.

Etymology:

The term was first used by Wolfgang Rindler in the 1950s.

Sample Sentence(s):

"The event horizon is the ultimate prison wall - one can get in but never get out."

                                             - Avi Loeb, chair of astronomy at Harvard University.

Lenticular Galaxy

(Last edited: Friday, 28 April 2023, 6:09 PM)


Source:


Short Definition:

A lenticular galaxy is a type of galaxy which contains a large-scale disc but does not have large-scale spiral arms.

Detailed Definition:

Galaxies can be divided into various types - spiral, elliptical, lenticular and irregular. A lenticular galaxy exhibits characteristics of both an elliptical and a spiral galaxy. It is determined by a central bulge and disks (as in the case of an ellipcital galaxy) combined with the absence of arms, which can be found in spiral galaxies just as the Milky Way. The name refers to the shape of the galaxy, which is very similar to a lens.

Etymology:

lenticular (lĕn-tĭk′yə-lər) - Latin lenticularis - having the shape of a double-convex lens

Sample Sentence(s):

"Lenticular galaxies tend to be old galaxies that have used up most of their gas and dust and are just living the twilight years."
