Galaxy Facts

The largest galaxies have nearly billion stars. There are an estimated   billion stars in the milky way, our galaxy. If you tried to count all the stars in just our galaxy at a rat of one star per second, it would take you about 3000 years.

The Birth of a Solar System
Most astronomers believe that all the members of the solar system, from the giant Sun to the smallest asteroid, were born out of a vast, spinning cloud of gas and dust – the solar nebula. The process began 5 billion years ago with the formation of the Sun. The planets and other objects formed from unused material. When the solar system was nearly complete, 500 million years later, just 0....

The square of Pegasus is the key pattern to look for. Its four stars, although not particularly bright, are easy to find because there are few other stars around.
Red Giant Stars Explained
A red monster is an iridescent monster star of level or halfway mass (harshly 0.5–10 sun oriented masses) in a late stage of stellar development. The external environment is swelled and tenuous, making the span monstrous and the surface temperature flat, an as yet undisclosed place from 5,000 K and easier. The manifestation of the red monster is from yellow orange to red, incorporating the unearth...

The "Messier Objects" were unknown objects in the sky, first noted from France astronomer Charles Untidier in his "List diethylstilbestrol Nébuleuses et diethylstilbestrol Amas d'Étoiles" ("Catalogue of Formulations and Superlegend Clusters"). It was initially released in 1771, with the final inclusion, made from later astronomers, manufactured in 1966. Messier objects were things in the sk...
Jupiter Explained: Inside and Out
Jupiter is the fifth planet from the Sun and the most vast planet in the Sun oriented System. It's a gas monster with mass one-thousandth that of the Sun but is more than two times the mass of every last trace of the different planets in our Earth's planetary group joined together. Jupiter is arranged as a gas monster plus Saturn, Uranus and Neptune. As one, these four planets are at times poi...

Driving Force That Drives Galaxies Apart
The universe is expanding at an ever – increasing rate, with something that astronomers call dark energy appearing to push it apart faster than gravity can pull it together. Type la supernovas are stars that explodes with a predictable brightness. Light from distant supernovas locks dimmer and redder than expected, implying that the universe is expanding. The more distant the star, the fast...
What a Mars Base Could Look Like
The thousand year project might begin with a series of a 18-month survey missions. Each crew making the six – month journey from earth to Mars would add a small habitation module to the base. An Atmosphere could be made by releasing carbon di oxide now frozen in dirt and polar ice caps. Factories spewing potent greenhouse gases, and maybe space mirrors focusing sunlight on ice, could start ...
50 Years of Spaceflight
In this era of 50 years of Manned Space Flight, USA stands at the top of the list in the Nations with the most Astronauts who have been sent to the space. Russia stands at the third position with France and Germany following it. The farthest Manned Missions from Earth is Apollo 13 which has travelled around 401,056 km in 1970. Next farthest is Apollo 8 followed by Gemini 11 and Gemini 10. Yur...
Jupiter's Moons Explained
The planet Jupiter has 67 affirmed moons. This gives it the most substantial entourage of moons with "sensibly secure" circles of any planet in the Sun oriented System. The most monstrous of them, the four Galilean moons, were identified in 1610 by Galileo Galilei and were the first protests recognized to circle a figure that was not Earth or the Sun. From the close of the 19th century, handfu...
What are Exoplanets?
In 1543, Polish astronomer Nicolaus Copernicus published on the Revolutions of the Heavenly Spheres, showing that the Earth, far from being the privileged center of the universe, is just another planet orbiting the Sun. Since then, the discovery that our sun is a typical star among the billions in the Milky Way, which in turn is but one of the billions of galaxies we observe in all directions,...

There are diverse multiverse theories, in which physicists have recommended that the universe may be one right around countless universes that moreover exist. The most distant separation that its hypothetically plausible for people to see is portrayed as the perceptible universe. Perceptions have demonstrated that the universe has all the earmarks of being stretching at a quickening rate, and vari...
Looking Inside the Sun
The Sun is our nearest star. It is a huge, luminous ball of gas like all the other stars. It consists mostly of hydrogen, and helium with tiny amounts of other elements. The Corona is the outer shell of the Sun’s atmosphere. It is extremely hot with temperatures reaching up to 2 million degrees. In the radiation zone, the energy is transported outwards by radiation. It covers about 70% of the Sun’...

How the Moon Influences the Earth
Although the moon is much smaller than the Earth, it still has an influence on its bigger companion. Just as the Earth’s gravity pulls on the Moon, the gravity of the Moon pulls on the Earth, stretching it into a slight oval. This distortion barely affects the solid landmasses, but it makes the oceans bulge on either side of the planet, producing the tides on either side of the planet. ...
