The second brightest star in the sky turns so fast that it has distorted itself. His bright blue light can already be seen at sunset, so go outside quickly when darkness falls.
Watch the Wega star at sunset.
The star Wega, the second brightest of the northern starry sky, is also the fourth brightest of all stars. Wega has a bluish glow because the star is about 9300 ° C hot. For comparison: the sun is hot at 5500 ° C.
Wega is one of the first stars to appear in the sky in the evening. His powerful light can be seen with the naked eye even before the sun sets behind the horizon.
Together with the stars Deneb and Altair, Wega forms the so-called Summer Triangle. The three stars are all among the brightest in the sky in the summer.
That's how you do that
In the first half of May you can see Wega around 25 degrees above the northeastern horizon, around sunset. During the night he travels east and climbs the sky.
Wega shines so bright that you can even see it in places with lots of artificial light. The Melkweg even bleaches a little.
Use a wide-angle lens for photos. Take the image vertically so that you take the foreground with you. With a tripod and self-timer you prevent your photos from being moved. Choose approximately 30 seconds of shutter speed.
Did you know?
At its equator, Wega rotates at almost 1 million km / h - more than 600 times as fast as the earth.
Because of that speed, the star has become oval, and if it would only turn 10 percent faster, it would collapse and go in all directions
