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.

Supernovas Explained
A supernova (shortened SN, plural SNe following supernovae) is a stellar outburst that is more enthusiastic than a nova. It's maintained /ˌsuːpərˈnoʊvə/ with the plural supernovae /ˌsuːpərˈnoʊviː/ or supernovas. Supernovae are greatly iridescent and create a blast of radiation that regularly briskly eclipses a whole universe, before blurring from perspective over some weeks or months. Aroun...

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 ...

Astrology Star Chart Spring
The positions of planets at the time of your birth are determined first. This forms the birth data. Your birth data is then compared to the positions of planets at various stages in life, to predict your future and major events that could happen in your life.

Understanding Auroras
The gathering storm is formed when the solar wind’s magnetic field is pointing in the opposite direction to that of the Earth, it sets up a chain of events that leads to a substorm and produces a Spectacular Aurora. The Earth’s magnetic shield, or magnetosphere, protects the planet from the solar wind, which usually just passes around the earth.

Atomic Discovery
Atomic theory is a theory of the nature of matter, which states that matter is composed of discrete units called atoms, as opposed to the obsolete notion that matter could be divided into any arbitrarily small quantity. The Atoms are subdivided into Nucleus. The Nucleus is formed with thousands of Nucleons. The Nucleons are again subdivided into Quarks. No matter how these are discovered, these di...

What Gravity does to Entropy
What qualifies as low entropy or high entropy depends on the situation. Physicists identify the high – entropy state of a system based on how the system evolves over time. For example, if a diffuse and sufficiently cool gas feels the tug of gravity, it evolves to a clump. The law of entropy increase then implies that the clump has high entropy, even though at first glance it might appear to be...

How Far are the Stars
Until 1838, Astronomers had little idea of the true size of the Universe. But in that year, Friedrich Bessel used a technique called the parallax method to make the first successful measurement of the distance to a star. Modern astronomers have many different ways of figuring out how far away an object is, but they all depend ultimately on the parallax method. As the Earth orbits the S...

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.

Sirius is the brightest star in the night sky. With a picture based clear degree of −1.46, it is for all intents and purpose twice as bright as Canopus, the subsequently brightest star. The name "Sirius" is dead set from the Ancient Greek ("sparkling" or "scorcher"). The star has the Bayer designation Alpha Canis Majoris.

Viewing the Past in Space
The ancients had it wrong: the Earth is not the center of the universe. But the Earths is at the center of the part of the Universe that we can see. A being on a planet orbiting, say, a star in the galaxy M87 would see a different part of the Universe, one centered on him.

Saturn and its Moons
Saturn is the sixth planet from the Sun and the second most expansive planet in the Earth's planetary group, following Jupiter. Named following the Roman god Saturn, its galactic image (♄) speaks for the god's sickle. Saturn is a gas mammoth with a middle range something like nine times that of Earth. While one and only one-eighth the mean thickness of Earth, with its more impressive volume Sa...

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.
