What are Stars – Scientific and Astronomical Analysis of Stars?
Stars are gigantic balls of gas, mostly hydrogen gas. There are so much gas and other material that the gravity of this huge gas-ball holds everything together. There is so much gravity that the gas becomes very dense and hot. Our own sun is a star. Fortunately, we are far enough away from it that the gravity of the gas can’t pull us in. It would be rather unpleasant inside of a star.
The gravity is strong enough that it squeezes the gas together so tight that nuclear fusion occurs. That means that the nuclei (centers) of the atoms get stuck together and ‘fuse’. This releases a lot of energy and causes the stars to heat up. The heat works its way from the inside of the star to the surface and then radiates into space. So what we see of stars is the energy released from the nuclear reactions inside their cores and then radiated from the surface. Since most stars are VERY far away, the light takes anywhere from a few years to millions of years to reach us. So the starlight that we see is very old indeed.
There are many different kinds of stars. They come in many sizes and colors. Some stars even orbit around each other. We call these binary stars. If you have any more questions about stars, please ask us to tell you more.
Arcturus (Swati Nakashtra), a red giant, looks orange to the eye. It’s the brightest star in the northern half of Earth’s skydome. Arcturus is especially noteworthy for its large proper motion or sideways motion across our sky. Only Alpha Centauri – our sun’s nearest neighbor among the stars – has a higher proper motion among the first-magnitude or bright stars in the stellar neighborhood.
It is a classic orange class K (K1) giant star with a precisely defined surface temperature of 4290 degrees Kelvin. To the eye, it shines 113 times more brightly than our Sun.
Its lower temperature, however, causes it to radiate considerable energy in the infrared. When this infrared radiation is taken into account, Arcturus actually shines almost twice as brightly, releasing 215 times more radiation than our Sun, from which we find a diameter 26 times solar, about a quarter the size of Mercury’s orbit. Arcturus is close and large enough so that its angular diameter of 0.0210 seconds of the arc can easily be measured, leading to a very similar direct determination of 25 times the solar dimension and providing nice confirmation of stellar parameters. Arcturus has a velocity relative to the Sun that is higher than other bright stars. Compared with the set of surrounding stars, which orbit the Galaxy on more or less circular orbits, it falls behind by about 100 kilometers per second (as do several others of the “Arcturus Group”).
The lagging movement has long suggested that the star comes from an older population of the Galaxy. Consistently, it is somewhat deficient in metals, having only about 20 percent as much iron relative to hydrogen as found in the Sun. A more intriguing suggestion is that the star actually comes to us from a small galaxy that merged with ours some 5 to 8 billion years ago. As a giant, weighing in at around 1.5 times the mass of the Sun, it has ceased the fusion of hydrogen in its core. Though it is somewhat brighter than we would expect for a stable helium fusing star, helium fusion to carbon has probably already begun. Such stars are not expected to have a magnetic activity like the Sun, but very weak X-ray emission suggests that Arcturus indeed is magnetically active and has a hard-to-observe “buried corona.”
Swati Nakshatra according to Vedic Scriptures
अम्बितमे नदीतमे देवितमे सरस्वति
— Rigveda 2.41.16
Best of mothers, the best of rivers, best of goddesses, Sarasvatī.
Saraswati is celebrated as a feminine deity with healing and purifying powers of abundant, flowing waters in Book 10 of the Rigveda, as follows:
अपो अस्मान मातरः शुन्धयन्तु घर्तेन नो घर्तप्वः पुनन्तु |
विश्वं हि रिप्रं परवहन्ति देविरुदिदाभ्यः शुचिरापूत एमि ||
— Rigveda 10.17
May the waters, the mothers, cleanse us,
may they who purify with butter, purify us with butter,
for these goddesses bear away defilement,
I come up out of them pure and cleansed.
Arcturus is the brightest star in the northern celestial hemisphere With a visual magnitude of −0.04, it is the fourth brightest star in the night sky, after −1.46 magnitude Sirius (Sanskrit it is known as Mrgavyadha “deer hunter”, or Lubdhaka “hunter”, the star represents Rudra (Shiva)), −0.86 magnitude Canopus (In Sanskrit it is known as ” Agastya ” – The sage ), and −0.27 magnitude Alpha Centauri (Found in the Anuradha Nakashtra in Scorpio Sign, The closest Star to our Solar system) . It is a relatively close star at only 36.7 light-years from Earth, and, together with Vega (The Pole Star – Dhruv Tara) and Sirius, one of the most luminous stars in the Sun’s neighborhood.
Arcturus is a type K0 III orange giant star, with an absolute magnitude of −0.30. It has likely exhausted its hydrogen from its core and is currently in its active hydrogen shell burning phase. It will continue to expand before entering the horizontal branch stage of its life cycle.
According to Vedic scriptures Swati is ruled by Vayu, the God of the Wind. This is the fifteenth nakshatra of the zodiac, having all its four quarters in Libra, spanning from 6°-40′ to 20°-00′. Nakshatra is closely linked with the air element, wind, breeze or knowledge of Akaash since Akaash is the abode of air.
This is One of most pious Nakashtra Associated with the ” Abode of Goddess Saraswati ” ruled by the Deity – ” Vayu “ – ” the wind God ” – Pawan Dev – one of 5th Elemental God ruling lower Earthy elements. One of Most Talented Nakashtra having Blessed from Goddess Saraswati – Shine like its Deep Brightness light like a pole star – Native born in this nakshatra will be Well learned, Talented and Knowledgeable in every art concerned with Maa Saraswati – Like Material, Philosophical, Spiritual, Art, Music, and Entertainment. Individually “Swati” means purity or more precisely the pure first drop of rain that the bird chatak always waiting for, that actually defines the characteristics of this star; seeking most purity, depth, and sharpness in every sense. The Sanskrit meaning of the word Swati also means ” a sword ” , sharp, penetrative in nature, that indicates sharpness or talent as exhibited by the natives of this nakshatra. Owned by the Lord Vayu and is also impacted by Rahu. As a result, both of these leave their effects on the nakshatra, imparting its attributes such as independence, spontaneity, complete freedom and restless behavior. The individuals are generally characterized by self-confidence and immense knowledge that they possess.
The native of Swati Nakshatra’s are highly independent souls who would not want to stay in any confinements as they are people who belong of the category of free thoughts with all pure feelings of peace and love around. These individuals like to stay kind till the time their freedom is not harmed as they could emerge really high on anger otherwise. They carry two personas as either they could be your best friend or their worst enemy.
They are the people of grave honesty and strict morals as they won’t ever see towards other’s wealth and possession neither they would ever like to share theirs with anyone else. They are the unbiased personas as they won’t predict anyone with their position and wealth. they hate criticism upon whatever they do either for self or anyone around.As Swati is ruled by the Vayu, the God of the Wind. It gives the power to scatter like the wind and has tendency to move in various directions. Its basic nature is changing its form into many when it is mixed with Fire it increases the power of fire and the same with water too only earth is ineffective of Vayu. because of the air element in Swati, that’s the reason it can bring change in nature and some time massive transformation due to negative traits of Swati. Air can shake the Basic nature of element and also lose its balance as it is Vata in nature.
Swati Nakshatra causes things to move and scatter in many directions. This nature can be very destructive as it has both healing and destructive powers. It brings major changes, transformations, and shifts of energy triggers that can be taken one to a higher level of existence.
They are true beings as they would appear what they are from inside and won’t ever carry two faces at the same time with uttermost purity and genuineness. They will do good to any extremes if others deserve to be , that while could also take revenge to any extent if you are not good to them. Altogether, they are straight forward beings.

The first pada falls on the Sagittarius Navamsa which is ruled by Jupiter. The pada stands for the inquisitive and restless aspect of Swati. It helps communication, learning and all sorts of travel. Planets generate comparatively favorable results as the pada is open-minded and eager.
The second pada falls on the Capricorn Navamsa which is ruled by Saturn. The quarter is an embodiment of materialism. It is the most grounded among the four padas and hence lacks the fragile element of Swati. However, concerns include material growth and stability. It is often hailed as selfish in comparison to the material aspects and personal comforts. There is a keen sense of business.
The third pada falls on the Aquarius Navamsa which is ruled by Saturn. Highly intellectual, the emphasis is on creativity, learning, and cooperation. The planets encourage group activities so that goals can be attained. Venus, Saturn, and Mercury are favorably placed.
The fourth pada falls on the Pisces Navamsa which is ruled by Jupiter. Most adaptable and flexible, this pada represents the spirit of Swati which is to go with the flow. A Pushkara navamsa pada, there is a success through perseverance, sociability, flexibility, and ingenuity. Although the planets might appear flimsy, they are goal-oriented and hardworking. All planets, other than Mercury, generate good results.
