CONSTELLATIONS- PART 3

-

Outlined below some of the well known Constellations of the Universe:



1. LYRA

Lyra is a small constellation. It is one of the 48 constellations discovered by the 2nd century astronomer, Ptolemy and is also one of the 88 modern constellations recognized by the International Astronomical Union. Represented on star maps, Lyra was often shown as a vulture or an eagle carrying a Lyre, and hence is sometimes referred to as Vultur Cadens or Aquila Cadens ("Falling Vulture" or "Falling Eagle" respectively). 

Vega is the brightest star of the constellation Lyra and also one of the brightest star in the night sky. It forms the corner of the framed Summer Triangle Asterism. The other stars of the constellation are Alafadar, Sheliak, Sulafat, Xihe, and Chason. 


Ring Nebula, also known as NGC 6720 and M57 is the best known planetary Nebula and the second to be discovered 2000 light years away from Earth is also hosted by Lyra. Lyra also contains Dumbbell Nebula, another planetary Nebula called Abell 46, NGC 6791 which is a cluster of Stars in Lyra, NGC 6745 and some other deep sky objects.

2. CANCER

Cancer is one of the 12 constellations of the Zodiac and is located in the Northern Celestial Hemisphere. It is also one of the 88 modern constellations. Bordered by Gemini to the west, Lynx to the north, Leo to the east, Hydra to the south, and Canis Minor to the southwest Cancer is a medium sized constellation. Cancer is invisible to the naked eyes. 


Altarf or Tarf is the brightest star in Cancer. The other stars are Acubens, Asellus Austrails, Asellus Borealis, Copernicus, Gakyid, Meleph, Nahn, Piautos, and Tegmine. Cancer ia well known to the stargazers as the home of Praesepe (Messier 44), an open cluster commonly known as the Beehive Cluster, which is located in the Constellation's center. It is one of our Solar System's closest open clusters, located around 590 light-years away. M 44 is made up of around 50 stars, the brightest of which are of sixth magnitude.

3. LIBRA

Libra is a constellation of the Zodiac and is located in the Southern Celestial Hemisphere. Libra lies between Virgo to the west and Scorpius to the east. Beta Librae, also known as Zubeneschamali, is the brightest star in the constellation. The brightest stars in Libra form a quadrangle that distinguishes it for the unaided observer. The other major star in Libra is Zubenelgenubi. Libra is the sign of Justice, balance, harmony, and the human ability to connect with others.


Libra is the home to one bright globular cluster, NGC 5897. It is a loose cluster, 50,000 light years from Earth; it is fairly large and has an integrated magnitude of 9. IC 1059 is a galaxy in the Constellation Libra. Bordered by the head of Serpens to the North, Virgo to the northwest, Hydra to the Southwest, the corner of Centaurus to the southwest, Lupus to the South, Scorpius to the east and Ophiuchus to the Northeast, Libra covers an area of 538.1 square degrees and it ranks 29th of the 88 modern constellations in size.

LIFE CYCLE OF A STAR!

-
Image
Outlined below are the many steps involved in a stars evolution, from its formation in nebula, to its death as a white dwarf or neutron star. NEBULA A Nebula is a cloud of gas(hydrogen) and dust in space. Nebulae are the birth places of stars. There are different types of nebula. An emission nebula e.g. such as Orion nebula, glows brightly because the gas in it is energized by the stars that have already formed within it. In a Reflection Nebula, starlight reflects on the grains of dust in a nebula. The nebula surrounding the Pleiades Cluster is typical of a reflection nebula. Dark Nebula also exist. These are dense clouds of molecular hydrogen which partially or completely absorb the light from the stars behind them e.g. the Horsehead nebula in Orion. Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf.   Shop now at Amazon Pantry at best deals Amazon Pantry STAR A star is a luminous globe of gas producing its own he...

GRAVITY

GRAVITY What is Space Time Continuum? Time is not completely separate from and independent of space, but is combined with it to form an object called space-time. It is a matter of common experience that one can describe the position of a point in space by three numbers, or coordinates. For instance, one can say that a point in a room is 7 feet from 1 wall, 3 feet from another and 5 feet above the floor. Or one could specify that a point was at a certain latitude and longitude and a certain height above sea level. One would not specify the position of the moon in terms of kilometres north and kilometres west of a building on Earth and some feet above sea level. Instead, one might describe it in terms of distance from the Sun, distance from the plane of the orbits of the planets, and the angle between the line joining the Moon to the Sun and the line joining the Sun to a nearby star such as Alpha Centauri. Even these coordinates would not be of much use in describing the position of the ...

THE SOLAR SYSTEM

Here are some amazing elements that our SOLAR SYSTEM consists.  1. Sun The Sun is a star present at the centre of the Solar System. It is spherical in shape and is emmiting huge amount of light and infrared radiations with heat due to the nuclear fusion reactions in its core. It is a type of G-Typemain Sequence Star with a life span of approximately 10 billion years.  2. Planets Our Solar System consists of eight planets named Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, ordered in their respective distances from the Sun.  The smallest and the nearest planet to the is Mercury and the largest planet is Jupiter. The hottest planet is Venus and the coldest is Neptune. Listed below is the time taken by every planet to rotate around its Axis and revolve around the Sun.

CRAZY SCIENCE EXPERIMENTS IN SPACE SHUTTLE

-
Image
Outlined below are some of the coolest Space Shuttle Science Experiments: 1. Microbes Get More Virulent In Microgravity. Experiments aboard the space shuttle have shown that salmonella bacteria, a   common and sometimes deadly source of food poisoning, get more virulent in space. Scientist believe that the bacteria get ramped up because space flight tricks them into behaving as if they're inside the human gut. The shuttle missions also identified dozens of genes that seem to be involved in the hyper-virulence, as well as "master switch" protein that regulates many of these genes.  2. Space Roses Smell Different. It sounds like some sort of symbolic or ceremonial gesture: The Shuttle Discovery carried a single rose to orbit on its STS-95 mission in 1998. But there was science, and business, behind the move. The company International Flavours and Fragrances (IFF) wanted to see how microgravity altered the sweet and familiar scent of a Rose — and if a new perfume component m...

NASA FOUND SALT TRACES ON MARS...

Recently, after the testing of the samples brought from the Red Planet (Mars), NASA said that there are some possibilities of organic salt present on Mars. After this research of NASA our understanding of Mars's surface will improve. Also this will help in finding life forms in Mars as well as on different Planets. In an interview NASA said that organic compound and salt traces on Mars could be a mark of geographical processes or bacterias, like that of found by the Curiosity Rover. Salts Could Be Made from Geological Processes..... According to one research, the iron, calcium and magnesium oxalate and acetate affected by radiation and oxidation together can combine to mix up with the organic salts. These salts could be made from Geological Processes or these are the remains of micro organisms. Possibilities Of Life On Red Planet Increases.... According to NASA traces of salt could increase the possibility of organic matter present on Mars. On Earth as well such type of life forms ...
