Groups may host events on either or both dates. Spring Astronomy Day occurs sometime between mid-April and mid-May on a Saturday near or before the 1st quarter Moon. Fall Astronomy Day occurs sometime between mid-September and mid-October. Astronomy Week was created to give sponsoring organizations a longer period of time to host special events.
In 2023
It will happen on December 22At 03:28 GMT (December 21
At 10:28 p.m. EST). It will be the shortest day in the Northern Hemisphere; the Southern Hemisphere
On the contrary
Will experience the greatest amount of sunlight and the longest day of the year. We prepared a fun and educational quiz about equinoxes and solstices for you.
It’s the best time for stargazing because the Moon’s light won’t hinder the view. The June solstice marks the first day of astronomical summer in the Northern Hemisphere and the first day of winter in the Southern Hemisphere. In 2023
It will happen on June 21
At 14:58 GMT (10:58 a.m. EDT).
It is almost impossible to look up at the night sky on a clear evening and not be caught up in the sense of wonder and amazement at how big the universe truly is compared to us. International Astronomy Day is a way for astronomy enthusiasts and professionals to share their knowledge and love of outer space with the general public.
The Saturday nearest to the first moon quarter is celebrated two times per year: autumn and spring. The next Astronomy Day will be held tomorrow, September 23, 2023. Astronomy enthusiasts have always wanted to look beyond the night sky filled with uncountable stars.
Astronomy Day is an annual event in various countries
Intended to provide a means of interaction between the general public and various astronomy enthusiasts
Groups and professionals.
Holiday in India
National Science Day is celebrated in India on February 28 each year to mark the discovery of the Raman effect by Indian physicist Sir C.V.Raman on 28 February 1928.
Persian astronomy or Iranian astronomy refers to the astronomy in ancient Persian history.
Time that it takes to complete one rotation relative to the background stars
The rotation period or spin period of a celestial object has two definitions.The first one corresponds to the sidereal rotation period
I.e.The time that the object takes to complete a full rotation around its axis relative to the background stars.The other type of commonly used rotation period is the object's synodic rotation period
Which may differBy a fraction of a rotation or more than one rotation
To accommodate the portion of the object's orbital period around a star or another body during one day.
Cycles used to predict eclipses of the Sun and Moon
The saros is a period of exactly 223 synodic months
Approximately 6585.3211 days
That can be used to predict eclipses of the Sun and Moon.One saros period after an eclipse
And Moon return to approximately the same relative geometry
A near straight lineAnd a nearly identical eclipse will occur
In what is referred to as an eclipse cycle.A sar is one half of a saros.
