NASA Skywatching Tips: Pay Attention to the Night Sky This September, Interesting Things Are Happening



The month appears to be beneficial for skywatchers with a whole range of binoculars and telescopic sights to come. According to NASA, throughout September, interesting cosmic events will occur and can be seen on the horizon. Astronomers and space enthusiasts will have to prepare quickly for the smallest Mercury, the space agency said in its monthly update. Planets About half an hour after sunset, the low will briefly appear in the west in the Solar System. Because Mercury is so small, only slightly larger than Earth's Moon and so close to the Sun, it is very difficult to see with the naked eye.

there's more. A clear view of the horizon will present some spectacular planetary clusters in the first half of this month. If you're looking at it from the far south, Mercury will be taller than the horizon, before it sets. Once you find Mercury, turn a little south for the brighter Venus, which is also closest to Earth planets Neighbour. On 9th and 10th the pair will be joined by the crescent moon.

All this and more were shared by "Skywatching Tips" NASA In an Instagram post.

The bright star between the two planets will be Spica. Two other bright stars that can be easily seen at dusk throughout September are Arcturus, the brightest orange-tinted star in the northern sky, and Altair, the bright white star that hangs just above Saturn throughout the month. . Altair spins very rapidly, which has flattened it into an oval shape.

To easily spot Arcturus in the night sky, first look at the Big Dipper aka "The Hull", which is called the Saptarshi constellation in ancient Indian astronomy. Follow its arc, the handle, to the south and the bright star will be Arcturus.

"At a distance of only 37 light-years from our solar system, Arcturus is the brightest star in the northern sky," NASA said.

Compared to other stars, Arcturus moves much faster with respect to our solar system. Before this interesting aspect about star motion was discovered, it was thought that the position of stars was fixed. Edmund Halley was the first to discover that stars rotate as independent objects.

On September 16, Moon, Saturn and Jupiter will be in close proximity. The September equinox will occur on the 22nd of this month when the Sun is just above the Earth's equator, so night and day will be of equal duration.
