Stars and constellations

Autumn officially arrives on September 22 in the northern hemisphere 21:54 Eastern Daylight Time, but the first three quarters of September belong to the summer.

In fact, the summer stars are still easy to see in the early evening hours. Deep in the southwest lies the orange-red Antares, often referred to as the "heart" of the constellation Scorpius, with the planets Jupiter and Saturn to the west and east, respectively. At Antares, far below left, are a few unlike bright stars, Shaula and Lesath, known as the "Cat's Eyes".

Scorpius' east is Sagittarius, the archer often identified by his "teapot" astonishment and directly above Scorpius is Ophiuchus, the serpent bearer whose left (eastern) foot lies between the scorpion and the archers.

The Sagittarius in the East is followed by the gloomy constellation of Capricornus, the Sea Goat. Scorpius, Ophiuchus, Sagittarius, and Capricornus are all constellations, meaning that the sun moves within its limits during the year, from late November to mid-February. Of course, these constellations are high during this period during the day, and so the overwhelming glare of the shining sun prevents them from being seen.

Standing in the early evening of September almost over the head is another feature of the summer. the summer triangle consisting of Vega in Lyra, Deneb in Cygnus and Altair in Aquila. The summer triangle is ideal for evening sightseeing in late summer and early autumn; In September, all three stars stay well above the horizon until well after midnight. Interestingly, the bright eastern star of the spring triangle, orange Arcturus in the constellation Boötes, the shepherd, is still in the west. Arcturus sets EDT after 1

0:30 in mid-September

Later that night, after the summer stars have wandered into the western half of the sky, the first stars of autumn appear in the eastern sky. After about 22 clock on the southeastern horizon rise. EDT is the white star Fomalhaut, which lies in the constellation Pisces austrinus, the southern fish. Also around this time is the Grand Place of Pegasus, four stars in the shape of a rectangle that lies at its edge. Deep in the northeast lies the famous "W" shape of the constellation Cassiopeia, queen of ancient Ethiopia. The "W" opens in the direction of Polarstern, the north star, so that you can locate it.

Naked-eye planets in the evening and morning skies

Venus shimmers like a yellow jewel in the evening sky. The spectacular evening "star" reaches its peak at the end of this month. Unfortunately, at dusk, Venus hovers quite low above the western horizon. On the first Venus, accompanied by the much weaker true star Spica on her right, sets in about an hour and a half after sunset or 9 pm. SUMMER TIME. At the end of the month, Venus sets less than an hour after the sun; At this time, a telescope will show a clearly crescent-shaped phase like that of the moon. The Venus will completely disappear from the evening sky in October, and then in November again in the early morning sky to be visible.

Jupiter remains a shining golden "star" that shines deep at nightfall in the southwest. Jupiter sets against 10 o'clock. September 1, and shortly after 8:30 pm on the 30th.

Far east of Jupiter, Saturn looks like a bright cream-colored star among the weaker, true stars of the constellation Sagittarius. When September begins, Saturn is almost exactly south at dusk and sets in at about 1am. At the end of the month, Saturn will go down at around 11:15. A telescope will reveal the great ring system of Saturn.

The bright, orange Mars is at dusk in the southeast of the southeast. Mars outshines Jupiter in early September, but it loses about half of its brightness towards the end of the month as the Earth-Mars distance spreads. Consequently, Mars falls to the brightest point among the planets, while Jupiter moves back to its usual rank as the second-brightest (after Venus). Mars sets a few minutes before 3 o'clock on the 1st and about 1 o'clock on the 30th.

Mercury is visible as a "morning star" during the first week or so of September; Look at dawn in the east for a bright, yellow "star". Binoculars will help a lot. After that, Mercury disappears at dawn and will reappear in the evening sky at the end of October.
