Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere.

What are the examples of astronomical phenomena known to astronomer before the invention of telescope?
Hipparchus (100 B.C.) produced first star catalog and recorded the names of constellations. During the times before the invention of the telescope, there were only seven objects visible to the ancients, the Sun and the Moon, plus the five planets, Mercury, Venus, Mars, Jupiter and Saturn.
What do astronomical phenomena mean?
Astronomical Phenomena. Aggregates of matter in outer space, such as stars, planets, comets, etc. and the properties and processes they undergo.
What is the importance of astronomical phenomena?
The motions of astronomical objects determine the day-night cycle, the seasons of the year, the tides, the timing of eclipses, and the visibility of comets and meteor showers. Easily observed astronomical events have formed the basis for time keeping, navigation, and myths or sagas in cultures around the world.
What are the 4 types of astronomy?
The four sub-fields of Astronomy are: Astrophysics; Astrometry; Astrogeology; and Astrobiology. The following gives a brief description of each sub-field and its focus. Astrophysics, as a scientific discipline, was born in mid-nineteenth century Europe.
Which astronomical phenomena was used as the basis of creating ancient calendars?
The principal astronomical cycles are the day (based on the rotation of the Earth on its axis), the year (based on the revolution of the Earth around the Sun), and the month (based on the revolution of the Moon around the Earth).
Which astronomical phenomena was used to mark the onset of seasons?
The familiar cycle of the seasons results from the 23.5° tilt of Earth's axis of rotation. At the summer solstice, the Sun is higher in the sky and its rays strike Earth more directly.
What are the 2 types of astronomy?
In the past century or so, astronomy has been broadly split into two camps — observational astronomy (using telescopes and cameras to collect data about the night sky) and theoretical astronomy (using that data to analyze, model and theorize about how objects and phenomena work).

What is constellation used for?
A constellation is a star group that forms a specific pattern or shape based on the positions of the stars. Constellations are used to map out the night sky and to recognise specific stars in the sky.
