Where do the Stars Go in autumn?

In contrast to the bright and pretty star fields of the summer Milky Way now slowly departing the scene in the west and the array of bright stars of winter beginning to make themselves evident in the east, we have the stars of autumn largely predominating our sky across much of the south.

What is the largest constellation in the sky?

The zodiac constellations Pisces and Aquarius are among the largest constellations in the sky, 14th and 10th in size respectively, and can be easily identified by two prominent asterisms, the Circlet of Pisces and the Water Jar. The Circlet of Pisces, which represents the head of the Western Fish, is located between the Great Square …

What is the name of the asterism in Aquarius?

Aquarius contains several bright Messier objects – the asterism Messier 73 and the globular clusters Messier 2 and Messier 72 – as well as the famous Helix Nebula, Saturn Nebula and Atoms for Peace Galaxy (NGC 7252). Pisces is home to the Phantom Galaxy (M74), a face-on grand design spiral galaxy visible even in large binoculars.

What is the name of the constellation with the first Sun-like star?

Pegasus is the seventh largest constellation in the sky. It contains a number of notable stars and deep sky objects, among them 51 Pegasi, the first Sun-like star discovered to have an orbiting planet, the bright globular cluster Messier 15 (Great Pegasus Cluster), the spiral galaxy NGC 7331 and the two unusual deep sky objects, the gravitationally lensed quasar known as Einstein’s Cross and Stephan’s Quintet, a striking visual grouping of five galaxies.

What is the name of the star cluster in Perseus?

Perseus is home to the famous eclipsing variable star Algol, two Messier objects – the bright open star cluster Messier 34 and Little Dumbbell Nebula (M76) – as well as to the famous Double Cluster, the California Nebula (NGC 1499), and many other interesting deep sky objects.

What is the closest galaxy to the Milky Way?

Andromeda, located right between the W and the Great Square, is best known for the Andromeda Galaxy (M31), the nearest major galaxy to our own, the Milky Way and the most distant object visible to the naked eye. The galaxy is so large that it appears as a small cloud in binoculars and can be observed and photographed even in small telescopes. The smaller satellite galaxies Messier 32 and Messier 110 require larger telescopes.

Where is Cetus located?

Cetus, named after the sea monster of the Greek myth about Andromeda, is located in the northern sky. Also known as the Whale, it is one of the largest constellations. Cetus lies in the region of the sky called the Water, along with several other constellations with names evocative of water: Eridanus (the river), Aquarius (the water bearer), Pisces (the fish), etc. Cetus is home to the barred spiral galaxy Messier 77 and several well-known stars: Deneb Kaitos (Beta Ceti), Menkar (Alpha Ceti), Tau Ceti and the famous variable star Mira (Omicron Ceti).

What is the brightest star in the constellation of Pegasus?

The best time to view the constellation of Pegasus is at 21:00 during the month of October. The July Pegasids are the only meteor shower associated with this constellation that contains many other noteworthy and spectacular deep sky objects, not many are visible with amateur equipment.

When are autumn constellations most visible?

Autumn constellations are the ones that are best observed in the night sky from late September to late December in the northern hemisphere, and from late March to late June in the southern hemisphere. In this article we are going to focus on the northern one.

How many stars are in M31?

M31 is the largest galaxy close to the Milky Way, and is counted as a member of the Local Group of galaxies, a collection of about 30 or so galaxies that collectivelly are also an outlying member of the Virgo Super Cluster of Galaxies. M31 is about 2.9 million light years away, and appears to be about six times as large as the full Moon, although the bright central bulge of the galaxy is visible only in small telescopes, while larger instruments will highlight the entire galaxy. It is estimated that M31 contains about 1 trillion stars, which is considerably more than the estimated 200 to 600 billion stars that make up the Milky Way.

What is the brightest star in the constellation Aquarius?

Aquarius. The Aquarius constellation’s brightest star is Sadalsuud ( Beta Aquarii) a yellow supergiant found 610 light years away of magnitude +2.87. the best time to view the constellation is at 21:00 (9 p.m.) during the month of October.

How many stars are in Messier 74?

Messier 74 (M74, NGC 628) While this galaxy is a text-book example of a classical grand design spiral galaxy, and is estimated to contain at least 100 billion stars, it has the lowest surface brightness of all the Messier objects, which makes it the most difficult Messier object for amateurs to observe.

How far away is M31?

M31 is about 2.9 million light years away, and appears to be about six times as large as the full Moon, although the bright central bulge of the galaxy is visible only in small telescopes, while larger instruments will highlight the entire galaxy.

Best time to the constellation of Andromeda is at 21:00 (9 p.m.) during the month of November. Andromeda is associated with the Andromedids meteor shower, also known as the Bielids, after the comet 3D/Biela. The shower was first documented in Russia on December 6, 1741, and although the shower has largely faded since then, some activity can still be observed during mid-November if conditions allow. The constellation contains a large number of notable deep sky objects, many of which are relatively easy targets for amateur telescopes and even binoculars. Below are some details of a few of the most prominent objects visible in Andromeda

What is the summer triangle?

How many stars are in the M15 cluster?

This cluster contains about 100,000 stars, and with an apparent magnitude of 6.2, it shines about 360,000 times brighter than the Sun. M15 is thought by most investigators to be about 12 billion years old, which makes it old enough to contain at least one known neutron star, designated M15 C. The cluster also contains a fairly large number of know variable stars and at least two know X-ray sources, designated Messier 15 X-1 and Messier 15 X-2, respectively. Furthermore, the cluster contains the planetary nebula Pease 1, which was the first planetary nebula to be discovered in a globular star cluster.

What does Aquarius mean in the 5th dimension?

It is a zodiacal constellation which traditionally represents a man holding a water jar or urn (marked by an inverted "Y"-shaped asterism of four stars), which is spilling a vaguely marked stream of water southward into the mouth of Piscis Austrinus, the southern fish.

What constellations are half man and half horse?

The ancients who had conceived the watery constellations must have had a very vivid imagination. Capricornus is an excellent example of this. A centaur is a half man and half horse, and a mermaid is a half woman and half fish. In Capricornus, now about halfway up in the southern sky at 9 p.m., we supposedly have a half goat and half fish, though its dim stars form a roughly triangular figure which might better suggest an inverted hat, or perhaps a sting-ray gliding toward you. At this moment in time, the western end of the sea goat is occupied by a bright yellow-white "star" which is really the planet Saturn. In late December, brighter Jupiter will shift east and will nearly merge with Saturn in what is being promoted as "The Great Conjunction," which will happen in Capricornus.

How bright is Mira?

At its brightest, Mira appears 250 times brighter, usually equal to a third-magnitude star, though on rare occasions it can get even brighter and in one year (1779) it became so bright that it nearly rivaled the first-magnitude star Aldebaran in the constellation of Taurus, the bull .

What hemisphere is the watery constellation in?

What planet is the sea goat?

In late December, brighter Jupiter will shift east and will nearly merge with Saturn in what is being promoted as "The Great Conjunction," which will happen in Capricornus.

What is the magnitude of a star?

Magnitude is a way that astronomers classify the brightness of sky objects, with the lower the figure of magnitude, the brighter the object. The brightest stars, for example, are either magnitude 0 or +1. If you live in a bright city or nearby suburb, your limiting magnitude might only be +3.
