Planetary Breakup Hercules Star Cluster Ring Nebula

Planetenzerfall, der Herkules-Sternhaufen und das Sternbild Leier

Skywatcher werden im Juni die Planeten Saturn, Mars, Jupiter, Venus, Herkuleshaufen und das Sternbild Leier sehen wollen.

Was steht im Juni an? Planetenzerfall, ein Hauptsymptom eines bekannten Sternhaufens, und das Sternbild Lyra.

Zu den Skywatching-Highlights für Juni 2022 gehört das Sammeln von vier Planeten mit bloßem Auge ([{“ 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.

Die Ansammlung der vier mit bloßem Auge sichtbaren Planeten, die wir in den letzten Monaten am Morgenhimmel genossen haben – einschließlich mehrerer enger Konjunktionen – begann sich aufzulösen. In den nächsten Monaten werden Saturn, Mars, Jupiter und Venus zunehmend verstreut am Morgenhimmel erscheinen – so sehr, dass Venus und Saturn für die meisten Beobachter im September als Morgenobjekte erscheinen werden.

Achten Sie im Juni auf diese zunehmend planetare Divergenz und beachten Sie, wie die Mondsichel am Morgen des 23. in die Aufstellung springt.

Der Juni ist eine ausgezeichnete Zeit, um einen der berühmtesten zu sehen Fußball-Star-Gruppen – M13, auch als Hercules-Gruppe bekannt. Kugelsternhaufen sind Kugelsternhaufen, die in ihren Zentren dicht gepackt sind. M13 selbst enthält Hunderttausende von Sternen.

Kugelsternhaufen sind ebenfalls sehr alt. Das Alter der Sterne in M13 wird auf etwa 12 Milliarden Jahre geschätzt, was dem Alter des Universums selbst nahe kommt. unsere galaxie zu hause,[{“ 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.

Heart of M13 Hercules Globular Cluster

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.

Hubble Ring Nebula (Messier 57)

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…
