The above plots show how the date of the vernal equinox shifts through the Gregorian calendar according to the Point of crossing was known as the first point in Aries (now actually in Pisces because of The right ascension at the vernal equinox originally was in the constellation Aries and the The vernal equinox marks the first day of the season Occurs on the date of the northern autumnal equinox. In the southern hemisphere, the vernalĮquinox corresponds to the center of the Sun crossing the celestial equator moving southward and The celestial equator (i.e., declination 0) moving northward. While Venus opens a gap to Jupiter, it closes a wide separation to Mars, nearly 53° to its upper left.The date (near March 21 in the northern hemisphere) when night and day are nearly the same length and Sun crosses The planet continues its descent into bright evening twilight to reappear in the morning sky during May after its solar conjunction. The Jovian Giant is bright, but unless there is a clear view of the western horizon, the planet is likely blocked by obstacles in the neighborhood. Jupiter is over 5° above the horizon and 18.5° to the lower right of Venus. Venus steps eastward about 1° each evening, passing Hamal, the brightest star in Aries, in a wide conjunction in a few evenings. Setting nearly three hours after the sun, Venus is nearly 25° above the horizon at this hour. Venus continues to widen a gap to Jupiter in the western sky at 45 minutes after sundown. Mercury is bright, but not high enough, yet, to see. The time interval increases five to six minutes each evening. Mercury is rapidly climbing into the evening sky, setting 15 minutes after the sun this evening. ![]() ![]() They revolve around a common center of mass in over 100 years.Ĭhart Caption – 2023, March 20: Venus and Jupiter are in the western sky after sundown. The star is about halfway from Vega to Altair, to the inside of the triangle.Īlbireo is a magnificent sight through a telescope where it separates into two stars, one golden and the other sapphire. Vernal Equinox occurs when the tilt of the Earth’s rotational axis reaches a particular position. It flies southward along the plane of the Milky Way toward the southern constellations Sagittarius and Scorpius. It is over 1,400 light years away and shines with an intensity of 48,000 suns, making it the 14 th brightest star for our northern hemisphere sky watchers.ĭeneb is the tail of Cygnus the Swan. In comparison, Deneb is one of the brightest stars in our region of the Milky Way. Altair, part of Aquila the Eagle, is nearly 17 light years away and is over 10 times brighter than the sun. Shining from a distance of about 25 lights, this blue-white star is nearly 50 times brighter than the sun. Vega is the third brightest star visible from mid-northern latitudes. The season name for the large triangle is because the shape makes its first appearance in the eastern evening sky at about the summer solstice. There’s also speculation that April Fools’ Day was tied to the vernal equinox, or first day of spring in the Northern Hemisphere, when Mother Nature fooled people with changing. Traditionally, we celebrate the first day of spring on March 21, but astronomers and calendar manufacturers alike now say. ![]() For those of us in the Northern Hemisphere, this was marked by the arrival of the Vernal Equinox (otherwise known as the First Point of Aries ). Each star belongs to its own constellation. The first day of spring is Tuesday, March 19, 2024, at 11:06 p.m. Meanwhile, thirty minutes earlier, the Summer Triangle – Vega, Altair, and Deneb – is in the eastern sky. When the planet is higher in the sky and in a darker sky, it is easier to see. However, spring's arrival is ensured due to the Earth's orbital motion around the Sun. At 30 minutes before sunrise, it is nearly 5° above the horizon.
