행성 붕괴, 헤라클레스 성단, 그리고 별자리 거문고

6월에 무슨 일이야? 잘 알려진 성단의 주요 증상인 행성 붕괴와 거문고자리.

2022년 6월 Skywatching 하이라이트에는 육안으로 4개의 행성을 수집하는 것이 포함됩니다([{” attribute=””>Saturn, Mars, Jupiter, and Venus) in the morning sky. Check these out, before they break up. There is also the Hercules Cluster, one of the most well-known globular clusters, which you’ll be able to see with just binoculars if you don’t have access to a telescope. Enjoy a nice view of the constellation Lyra, which is easy to locate by looking for Vega, one of the brightest stars in the sky.

우리가 지난 몇 달 동안 아침 하늘에서 즐겼던 육안으로 볼 수 있는 네 개의 행성의 집합(몇 번의 밀접한 결합 포함)이 풀리기 시작했습니다. 앞으로 몇 달 동안 토성, 화성, 목성, 금성은 아침 하늘에 점점 더 흩어져 보일 것입니다. 그래서 금성과 토성은 대부분의 관찰자들에게 9월까지 아침 물체로 나올 것입니다.

6월에 이 점점 더 커지는 행성의 발산을 찾아보고 23일 아침에 라인업에 초승달이 뛰어드는 것을 확인하십시오.

6월은 가장 유명한 축구 스타 그룹 – 헤라클레스 그룹으로도 알려진 M13. 구상성단은 중심에 빽빽하게 들어찬 별들의 구상성단이다. M13 자체에는 수십만 개의 별이 있습니다.

구상 성단도 아주 오래되었습니다. M13에 있는 별의 나이는 약 120억 년으로 추정되며 이는 우주 자체의 나이에 가깝습니다. 우리 은하의 집,[{” attribute=””>Milky Way, is known to have about 150 globular clusters. They orbit outside the galaxy’s disk, traveling tens of thousands of light-years above and below its spiral arms and most of its stars.

Now, the Hercules Cluster is best observed with a telescope, and larger telescopes will allow you to see more of the cluster’s stars. But you can also find it with a pair of binoculars, where it’ll look like a hazy little spot.

Find M13 in the constellation Hercules, which is high in the east in the first couple of hours after dark in June.

This image, taken by the Advanced Camera for Surveys on the Hubble Space Telescope, shows the core of the great globular cluster Messier 13 and provides an extraordinarily clear view of the hundreds of thousands of stars in the cluster, one of the brightest and best known in the sky. Just 25,000 light-years away and about 145 light-years in diameter, Messier 13 has drawn the eye since its discovery by Edmund Halley, the noted British astronomer, in 1714. The cluster lies in the constellation of Hercules and is so bright that under the right conditions it is even visible to the unaided eye. Credit: ESA/Hubble and NASA

First look for the bright stars Vega and Arcturus.

Then find the four stars that comprise “the Keystone,” which is the pattern making up the central part of Hercules.

You’ll find M13 about a third of the way between the two stars on the western, or leading, side of the Keystone.

So check out the Great Globular Cluster in Hercules, M13, in June, and find yourself staring at an ancient gathering of stars that soars high above the Milky Way.

Finally in June, a quick introduction to one of the smaller constellations that’s home to one of the brightest stars.

That’s the constellation Lyra.

It represents a lyre, or harp, played by the musician Orpheus in Greek mythology.

In Arab cultures, as well as ancient Egypt and India, Lyra was seen as an eagle.

And the Inca of South America saw it as a llama.

Find Lyra by looking for Vega, which is the westernmost of the three bright stars in the Summer Triangle.

This image shows the dramatic shape and color of the Ring Nebula, otherwise known as Messier 57. From Earth’s perspective, the nebula looks like a simple elliptical shape with a shaggy boundary. However, observations combining existing ground-based data with new NASA/ESA Hubble Space Telescope data show that the nebula is shaped like a distorted doughnut. This doughnut has a rugby-ball-shaped region of lower-density material slotted into its central “gap,” stretching towards and away from us. It is located about 2,500 light years from Earth in the Lyra Constellation. Credit: NASA, ESA, and C. Robert O’Dell (Vanderbilt University)

In the Northern Hemisphere, you’ll find it halfway up the eastern sky in the first couple of hours after dark in June.

Vega is by far the brightest star in Lyra.

It’s the fifth brightest star in the sky and the second brightest in the Northern Hemisphere, after Sirius.

A pair of binoculars will help you see the others stars in Lyra, which form a sort of parallelogram hanging beneath it.

It’s sometimes described as looking a bit like a diamond ring, with Vega as the diamond.

And that’s not the only ring in Lyra. It’s also home to the famous Ring Nebula, where a star has blown off most of its outer layers, leaving behind a remnant star known as a white dwarf.

So let the bright star Vega lead you to Lyra, the harp constellation, in the June sky. And if you see it as an eagle, or a diamond ring, or a llama, well that’s perfectly okay too…
