My Reflections:

A. Which concept on the topic did you find easy to understand? What make them interesting?

• It is easy to understand the definition of constellations as well as knowing the zodiac signs, well it is not new for me and almost in my day to day life i had encountered them. It is interesting to know that there are many constellations and i had only few. well what is more fascinating that these constellations are made by God, wonderful' isn't it?

B.What are your personal discoveries or learning while studying this topic?

• That knowledge about this topic were came from the early cultures. That constellations plays a vital role in the early civilization from religious purposes, making it into calendar and into navigation. We thought  that these stars are just mere object in the sky that twinkles but for others it has significant use.

C.Which area or concept you would expound more?

• Even i knew the constellation but i cant locate it in the sky on my own. I can't connect the star to form pattern, sheme on me but i will work on it.

HELLO, MY NAME IS NIÑO DARYL DATULAYTA. I MAY BE A STRANGER TO YOU BUT SPARE ME SOME TIME TO TELL YOU A LITTLE BIT OF ME. I AM IN 9TH GRADE AND SO FAR SO GOOD WITH GOD'S GRACE.

What is Constellations?

• A constellation is a group of stars that, when seen from Earth, form a pattern.

• In modern astronomy, a constellation is a specific area of the celestial sphere as defined by the International Astronomical Union (IAU). These areas mostly had their origins in Western-traditional asterisms from which the constellations take their names. There are 88 officially recognized constellations, covering the entire sky.^[1]

Thus, any given point in a celestial coordinate system can unambiguously be assigned to a constellation. It is usual in astronomy to give the constellation in which a given object is found along with its coordinates in order to convey a rough idea in which part of the sky it is located.

Some Constellations

Some Constellations:

ANDROMEDA Andromeda (the princess, the daughter of Cassiopeia) is a northern hemisphere constellation. Alpha Andromeda (called Sirrah, meaning "Horse's navel") is the same as Delta Pegasi (from the constellation Pegasus).

AQUARIUS [Abbreviation: Aqr] Aquarius (the water bearer) is a constellation of the zodiac. This faint constellation is seen along the ecliptic. The sun passes through Aquarius from mid-February until mid-March. There are many interesting celestial objects in this large constellation, including globular clusters (M2 and M72),planetary nebulae (NGC 7009 and NGC 7293), the star group M73, a double star (zeta Aqr). Aquarius is the radiant for the meteor showers: March Aquarids, Delta Aquarids, Eta Aquarids, and Iota Aquarids. Alpha Aquarii (the brightest star in Aquarius) is called Sadalmelik (meaning the Lucky One of the King) and beta Aquarii (the second-brightest star in Aquarius) is named Sadalsuud (meaning the Luckiest of the Lucky); they are twin supergiants.

ARIES [Abbreviation: Ari] Aries (the ram) is a constellation of the zodiac located along the ecliptic between Pisces and Taurus. This tiny, faint constellation is seen just north of the ecliptic. The brightest star in Aries (Alpha Ari) is Hamal, the second-brightest star (Beta Ari) is Sharatan, the third-brightest star (Gamma 2 Ari) is Mesarthim, and the fourth-brightest is Botein (Delta Ari)

BIG DIPPER The Big Dipper is a group of 7 stars (it is an asterism and not a constellation) contained in the Northern Hemisphere constellation Ursa major (The Great Bear).

BOÖTES Boötes (the herdsman) is a large constellation in the northern hemisphere. The brightest star in Boötes isArcturus, a red giant that is the fourth brightest star in the sky.

CANCER [Abbreviation: Cnc] Cancer (the crab) is a very faint constellation of the zodiac that is shaped like a crab. Cancer is seen along the ecliptic and is located between Leo and Gemini. At the center of the crab's shell is a huge open cluster, the Beehive cluster, also known as Praesepe (M44). The open cluster M67 is nearby. The brightest star in Cancer is Acubens (meaning claw); the second-brightest is Al Tarf (meaning tip).

CANIS MAJOR Canis major (The Great Dog) is a constellation near Orion. The brightest star in Canis Major (and the brightest star in the sky) is Sirius, also known as the dog star. Canis Major is one of the constellation Orion's hunting dogs (together with Canis Minor).

The brightest star in Canis Venatici is Cor Caroli (alpha CVn), a blue-white star (magnitude 2.9) with a companion star (magnitude 5). The Whirlpool Nebula (M51), the Sab galaxy (M94) and the globular cluster M3 (magnitude 6) can be found in Canis Venatici. The Canes Venaticids meteor shower occurs from January 13 - January 30. Canes Venatici was named by the Polish astronomer Johannes Hevelius in 1690.

CAPRICORNUS [Abbreviation: Cap] Capricornus (the goat) is a constellation of the zodiac. Capricorn is seen along the ecliptic between Sagittarius and Aquarius. The brightest stars in Capricornus are Prima Giedi (Alpha 1 Cap) and Secunda Giedi (Alpha 2 Cap). The globular cluster M30 is in Capricorn.

CASSIOPEIA Cassiopeia is an easily-seen constellation that is in the far northern sky. It circles the pole star (Polaris) throughout the year and also straddles the Milky Way. The five major stars of Cassiopeia (also known as "The Lady of the Chair") are shaped like a "W" (or an "M," depending on your orientation). All of the stars in Cassiopeia are all less than second magnitude brightness. The brightest star in Cassiopeia is Schedar (alpha CAS), which is a multiple star that is pale rose in color and varies in magnitude from 2.2 to 2.8 magnitudes. The second-brightest, called Caph (beta CAS), is a white star of magnitude 2.4. Cassiopeia contains two open clusters, M52 (magnitude 7.3) and M103 (magnitude 7.4). The strongest radio source, Cassiopeia A, emanates from Cassiopeia; it is the remnant of a supernova which ocurred about A.D. 1660, and is 10,000 light years from us. The constellation Cassiopeia was named for Cassiopeia, the mother of Andromeda (and the wife of Cephus) in Greek mythology.

CEPHEUS Cepheus is a house-shaped constellation in the Northern Hemisphere. It is a circumpolar constellation; it never dips under the horizon in the Northern hemisphere. Errai (Gamma Cephei) is a third-magnitude orange subgiant star that will become the Earth's north polar star in 2,000 years. Cepheus is next to the constellations Andromeda and Perseus.
