The Pleiades is the star of the November sky with a partial lunar eclipse at the end of the month

Chances are you will come across a few products for the month named after a celestial body. Another notable brand is the Subaru. Their coat of arms consists of six stars, with one now more prominent, and is the badge adopted by a conglomerate founded by six Japanese manufacturers in the 1950s. Japan of the Pleiades star cluster in Kim Nguu.

The compact swarm is more commonly known as the Seven Sisters and is now visible above the eastern horizon after dark, with its brightest five or six members easily visible. first sight. Some observers think it looks like a small version of The Plow, which is a very good description.

While a few additional stars can be selected with the naked eye, with binoculars the Pleiades is truly breathtaking. The field was dotted with countless sparkling fragments of cut crystal and the bluish-white glow of these suns hints at their youth.

This cluster is about 1

15 million years old and is located about 445 light years away from us, so the light we see this month begins its journey just before Galileo was the first to sketch the Pleiades. through the telescope in winter 1609/10. A drawing in his great work Siderius Nuncius shows several dozen stars.

We now know of over a thousand individuals in the group, all born in the same spatial dimension. Over time, our galaxy’s gravitational influence will disrupt the cluster and the Pleiad will follow their separate paths. The long exposure shots show a scene shrouded in gas and dust illuminated by starlight, but this is an accidental encounter with an interstellar cloud as the embryonic matter of the cluster itself. stars have disappeared long ago.

Because they are located near the celestial equator, the Pleiades are visible all over the world and woven into various legends, as well as descriptive names like those listed in An’s Foclóir Réalteolaíochta Swims like a tÉillín (“brood” or “clutch”), a Streoillín (“stray path”), and a Tréidín (“the herd”). Indeed, the similarity of birds is noted by many early cultures.

The Pleiades are often associated with the onset of cold months or holidays for the souls of the dead, as their peak at midnight is the peak of winter and for the Druids, the Samhain festival. The presence of the cluster is still measured by some natives to predict whether it will be too wet or drought for planting, while they are also believed to delineate sailing season in the Mediterranean regions.

Easily overlooked in Taurus is another prominent star cluster known as Hyades. This more dispersed group has a V-shaped pattern pointing away from the orange star Aldebaran, which is not itself a member since it is only half away. Hyades is much older than the Pleiades and is a laboratory for testing theories about the evolution of stars.

In Greek mythology, the Pleiades was the daughter of Atlas and Pleione, with six of the seven gods married. The other daughter Merope is said to have perished after her marriage to a mortal. It is interesting that we find references to this “missing” Pleiad in stories from all over the world. Some have suggested that the star had actually lost its brightness in the past, but other stories mention another missing Pleiad. Puzzles still linger, just as the beautiful sisters continue to charm and fascinate these evenings.

The last lunar eclipse fell on November 8, the new moon on the 15th and the first lunar eclipse on the 22nd, the full moon on the 30th coincided with a partial lunar eclipse in the first half.

These types of lunar eclipses are more subtle because the moon only sinks into the more diffuse outer part of Earth’s shadow created in space.

The eclipse begins at 7:32 a.m. on the 30th but you won’t notice anything until close to the moon at 8:22 a.m. That is the more honest hope and given that the moon’s glare is turned off when it gets low, this could help accentuate any very slight stains near the top of its disc. We will miss the maximum of the eclipse at 9.42am as it happens after the moon from here.

Mercury is visible in the morning sky during November but is highest on the southeast horizon around 6:45 am on October 10. It can be found in the lower left of Venus and near Spica. at this point but a bit brighter than the star. The moon also acts as a guide when near on the morning of the 13th and 14th.

Venus rises three hours before the Sun a month and dominates the eastern sky before dawn appears first. It appears to narrow the daily gap with Mercury but no further than 12 degrees (a little more than the width of a fist) on day 13. Their separation will remain static for about a week before extending again. when Mercury sets towards the sun.

That is to say, Mars is receding in the rearview mirror, because Earth is now past it in our faster orbit. But the planet still burned bright orange in the eastern sky as soon as darkness fell and was observed until the early hours. The ape moon is near Mars on the evening of the 25th.

Jupiter and Saturn share the same low-power binocular field of view in early November but are only half apart by the end of the month as the distance between them slowly narrows. These two planets can be found in the southwest these evenings and placed after 8pm. Look for them in the upper right of the Moon on the 19th.

The two active meteor showers in November are the Leonids and the northern Taurids. The rate from before is usually very low during its peak on day 16 but hits hurricane levels every 33 years or so when the relevant parent comet returns to the inner solar system, the next thing that happens. in 2032.

Northern Taurids peak at night on 11 November and are generally low. But they can be surprising and sometimes produce slow-moving fireballs.

Space flight

A new launch date for Crew Dragon’s next mission to the International Space Station is set shortly after the October article is published. The mission is currently scheduled to take off on November 11 and will bring four additional members of the newest Expedition crew to the station.

The ISS’s morning passage time lasted until November 9, after which it shifted to the evening sky from 20th. Projections for your position can be calculated on Heavens Above.

Chang’e, named after the Chinese goddess of the Moon, is the Chinese Moon discovery series that first started in 2007 when Chang’an 1 reached lunar orbit. Chang’e 5 is a return mission to the robot model scheduled to launch in late November. Current plans are to collect about 2kg of material from below the surface of the Moon and then return. Earth.
