These maps show stars visible all year in the northern and southern hemispheres. They also mark the position of interesting objects, such as star clusters and galaxies. To see what is visible, face north in the northern hemisphere and south in the southern hemisphere.
The Variable stars contains pulsating variables, the eclipsing variables and the rotating variables. Toward the end of their lives, stars often pulsate, varying in brightness, temperature and size. Some pairs of stars are so close to each other that they look like a single star. In addition, if their orbits are angled edge-on to the Earth, each start periodically passes in front of its companion. Some stars vary because their surfaces are covered with spots similar to sunspots.

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.

How Eclipses of the Sun Happen
In its 27 – day Orbit of the Earth, the Moon sometimes passes directly in front of the Sun and we see a solar eclipse. In one of the natural world’s most eerie, beautiful spectacles, the dark circle of the Moon gradually creeps over the Sun. Between two and five solar eclipses are visible from somewhere on the Earth each year. When the Moon is at its farthest from the Earth, it is not ...

Comic Microwave Background and the Big Bang
Electrons unite with protons and neutrons to structure particles, ordinarily hydrogen and helium. Light can at final sparkle. Gravity makes hydrogen and helium gas mixes to shape the goliath fogs that can come to be universe sized frameworks; more unobtrusive packs of gas ruin to structure the first stars.

Star Map - Southern Hemisphere September to February
Polar Star has sufficient body ability to ingest the elevated-controlled ice slamming normal to her operations. The shell plating and cohorted interior uphold structure are created from steel that has particularly great flat-temperature quality. The part of the body outline to slam ice is 1-3/4 creeps (45 mm) thick in the bow and stern areas, and 1-1/4 crawls (32 mm) thick amidships. The frame...

The Sun Explained: Inside and Out
The Sun is the star at the focal point of the Earth's planetary group. It's just about splendidly round and comprises of blazing plasma entwined with attractive fields. It has a breadth of about 1,392,684 km, in the ballpark of 109 times that of Earth, and its mass (about 2×1030 kilograms, 330,000 times that of Earth) explains about 99.86% of the sum mass of the Sun oriented System.

Saturn's Moons
The moons of Saturn are various and differing, extending from small moonlets less than 1 kilometer crosswise over, to the gigantic Titan, which is more extensive than the planet Mercury. Saturn has 62 moons with affirmed circles, 53 of which have names, and just 13 of which have widths heftier than 50 kilometers. Saturn has seven moons that are impressive enough to be ellipsoidal because of...

Deflecting Asteroids
Every object exerts a gravitational pull, including a single spacecraft. Merely by hovering above the asteroid. It could pull the rock off course. The approach could even be tried with the Dawn spacecraft, scheduled to finish its tasks in the asteroid belt by 2015. However, such a strategy would be very slow, requiring years or even decades to alter the path of the asteroid.

Filtering Starlight Shown Graphically
The color of planets depends on the spectrum of the star’s light, which astronomers can easily observe, and filtering of light by air and water, which the author and her colleagues have simulated based on the likely atmospheric composition and it’s own effects.

A Brief History of the Solar System
The process of existence or initiative of life in the Solar System looks very interesting. Life in the solar system is a monomeric nucleotide, pretty much just a simple molecular compound made out of a normal, every-day inorganic material. Life started in the Earth once the things inside it are cooled down a bit. Basically life in the Earth is a replicator, the way it just happened or formed. Life...

Uranus Explained: Inside and Out
Uranus is the seventh planet from the Sun. It has the third-most vast planetary span and fourth-most impressive planetary mass in the Earth's planetary group. Uranus is comparative in arrangement to Neptune, and both are of offbeat substance structure than the more vast gas goliaths Jupiter and Saturn. Astrochemists in some cases place them in a marked classification called "ice goliaths". Ura...

The Space Capsule
The Space Capsule has been developed for NASA to service the International space station; the reusable Dragon capsule is lofted into orbit by Spacex’s Falcon 9 rocket. While the first flights are to carry cargo only, the capsule was designed to be capable of carrying up to seven astronauts.

What TV Shows are Aliens Watching Now? What Happened to our TV Shows?
If extraterrestrials were watching our TV shows, this is what they would be watching, depending on where they are in space. This concept is extremely interesting, because our TV shows are never lost, they are still being broadcasted in different areas of the universe. Waves travel nearly forever in space, unless an outside force acts on them.

Radio Astronomy
Radio waves are the same type of waves as light. They have less energy than visible light and so have a longer wavelength, but they travel at the same speed as light. At night our eyes and optical telescopes sees light from stars. But normal stars only produce radio waves very weakly.
