Astronomy enthusiasts watch during the hottest time of the year one of the most spectacular phenomena that can be seen in the night sky, known as the famous “Summer Triangle”.
The Summer Triangle is a formation of three very bright stars that are brightest in the northern hemisphere during the summer.
This formation, which can be observed after sunset, includes the bright stars Deneb, Vega and Altair, all of which rise above the eastern horizon from the sky.
The “Summer Triangle” is an annual feature of the northern summer sky that remains visible until the end of December, according to geophysicist Chris Vaughan, a SkySafari amateur astronomer who oversees Space.com’s night sky calendar.
Stars are especially bright in July and August, when they shine around midnight, according to Science Focus.
And if the sky is clear and dark enough, you can see the Milky Way stretching between an eagle, an eagle in flight, and a chicken’s tail as the Summer Triangle travels across the night sky, only to be high in the western sky at dawn.
The tallest and brightest star in the trinity is Vega, shining in the constellation Lyra with a magnitude of 0.03. Eagle is located only 25 light years from the Sun and is relatively easy to see because it is the brightest star in the summer sky. (On the scale of fate used by astronomers, lower numbers indicate brighter objects. For example, in its brightest light, Venus shines at about -4.6.)
In the lower right (south) corner of the triangle is the Flying Eagle, a star whose absolute magnitude (measurement of the luminosity of any astronomical body on a logarithmic scale) is 0.75 in the constellation Vulture. The star is located only 17 light years from the Sun.
“In contrast, the chicken tail, which appears somewhat less bright, has an apparent magnitude of 1.25, which is surprising at 2,600 light-years away,” Vaughan writes. The Cygnus star is in the constellation Cygnus.
