Definition of UTC (Coordinated Universal Time):

Coordinated Universal Time or UTC (an intermediate between the English version Coordinated Universal Time CUT and the French version Temps universel coordonné TUC) is the main time standard by which the world regulates clocks and time.

It is one of several closely related successors to Greenwich Mean Time (GMT). For most common purposes, UTC is synonymous with GMT, as GMT is no longer the defined standard for the scientific community.

Definition of Conjunction in Astronomy:

Two stars are in conjunction when observed from a third (generally the Earth) are at the same celestial longitude. As the celestial latitude may be different, the stars are very close in the sky, although they do not coincide, passing one above the other. The conjunction is one of the main aspects of the planets. It is also applicable to any celestial object that is visually located next to another.

Definition of Perigee in Astronomy:

It is called perigee (from the Greek adjective περίγειος) to the point of the elliptical orbit that a natural or artificial body travels around the Earth, in which said body is closer to its center. In perigee the orbital speed is the maximum of the entire orbit.

Definition of Apogee in Astronomy:

Apogee (from the Greek ἀπό ‘apart, away from’ and γεω- ‘terrestrial, relative to planet Earth’) is the point in an elliptical orbit around the Earth at which a body is farthest from the center of the Earth. The opposite orbital point, the closest one, is called perigee.

Definition of Equinox:

The equinoxes (from the Latin aequinoctium (aequus nocte), “equal night”) are the times of the year when the Sun is located in the plane of the celestial equator. On that day and for an observer on the Earth’s equator, the Sun reaches its zenith (the highest point in the sky in relation to the observer, which is just above his head, that is, at 90 °). The declination parallel of the Sun and the celestial equator then coincide.

It occurs twice a year: between March 19 and 21 and between September 21 and 24 of each year.

As its name indicates, on the dates when the equinoxes occur, the day lasts approximately equal to that of the night at the equator and in the latitudes close to it.

The equinoxes are used to set the onset of spring and fall in each earth’s hemisphere.

What is a Meteor Shower?

A meteor shower is a celestial event in which the irradiation of various meteors is observed from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids that enter Earth’s atmosphere at extremely high speeds in parallel paths. Most meteors are smaller than a grain of sand, so almost all of them disintegrate and never reach the Earth’s surface. Very intense or unusual meteor showers are known as meteor bursts and meteor storms, which produce at least 1,000 meteors per hour, mostly from the Leonids. The Meteor Data Center lists more than 900 possible meteor showers, of which about 100 are well established. Several organizations point to Internet viewing opportunities. NASA maintains a daily map of active meteor showers.

What are the Moon Phases?

The lunar phases (also phases of the Moon) are the apparent changes of the visible illuminated portion of the satellite, due to its change in position with respect to the Earth and the Sun. The complete cycle, called lunation, is 29.53 days, during which the moon passes the new moon, its visible illuminated portion gradually increases again, and two weeks later, the full moon occurs and, around the following two weeks, it decreases again and the satellite enters the new phase again .

Finally, a perfect alignment between the Sun, the Earth and the Moon occurs, which results in eclipses. A solar eclipse occurs when the Moon passes in front of the solar disk, and can only occur on a new Moon, while a lunar eclipse occurs when the Moon passes through the Earth’s shadow, which can only occur on a full Moon. This transition between phases has been used to measure time, which is why many lunar calendars were created based on the lunar cycle (moon phase). The moon actually takes eighteen days and it happens because the sun and the Earth align with each other, having said that the moon is forming.
