The work of the Austrian physical Ludwig Boltzmann suggested an answer to the question: why does time seem to go only in one direction ?
Boltzmann suggested that the amount of disorder, or entropy, in the universe increases over time.

Mercury Explained: Inside and Out
Mercury is the deepest planet in the Earth's planetary group. It's additionally the most diminutive, and its circle is the most unconventional (that is, the slightest splendidly roundabout) of the eight planets. It circles the Sun once in the vicinity of 88 Earth days, finishing several revolutions about its hub for each two circles. The planet is named following the Roman god Mercury, the det...

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. ...

Nearside of the Moon
The dominant features on the Moon’s nearside – the side that always faces the Earth – are the dark maria, which early astronomers thought were seas. These lava – filled basis formed when molten rock seeped through the Moon’s crust to fill depressions left by meteorite impacts.

Protostar Evolutions
Protostar Evolution in detail contains a random amount of interstellar gaseous matter, mainly hydrogen, containing traces of dusts (ices, carbon, rocks).

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.

Space Object Comparisons
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.

Star Map - Northern Hemisphere June to November
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.

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...

Apollo Lunar Module Descent Stage
The Lunar module Descent stage would be the final module for the vehicle. The Stage consists of the Engine Mount, The Descent engine, the Structural Skin, the Insulation, the thermal and micrometeoroid shield, the forward interstate fitting, the oxidizer tank, the cable cutter, the ambient helium tank, the landing gear and finally the descent engine skirt.

Some of the Missions that have been flown to Mars are Mariner 4, Mars 3, Mars 5, Mars 6, Phobos 2, Mars Express, Dawn. Many have been successfully sent to the Mars and some of them with partial success.It's interesting to see the trend that trips to Mars have taken. Particularly how the USSR sent many probes to Mars before the USA, but the USA had the first successful mission. Check out the other...

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.

The Milky Way in a Diagram
Home galaxy of Earth, the Milky way is a spiral – shaped system of a few hundred billion stars. Bright regions of recently formed stars highlight its arms, while older stars explode or expel their outer layers as beautiful planetary nebulae, then fade away and die. A thick swarm of orange and red stars marks the galactic bulge, encapsulating the star-packed galactic center.

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.

Black Holes Explained
The most Bizarre objects in the Universe, black holes are aptly named – they emit no visible light at all. And yet, most black holes are the end state of the most brilliant objects in the cosmos; giant stars that go supernova. The super compressed core that remains after the explosion has such strong gravity that even light cannot escape it – so the object is black.
