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.

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....
Old Time Map of Celestial Objects
The divine circle might be acknowledged to be interminable in sweep. This denotes any focus within it, incorporating that involved by the spectator, might be recognized the inside. It moreover indicates that everything parallel lines, be they millimeters separated or crosswise over the Earth's planetary group from one another, will appear to cross the circle at a lone indicate, comparable to the v...
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. What the uncovered eye perceives as a particular star is blatantly a paralle...
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.
How to Understand Relativity
Spacetime is CONSTANT (always 100%). Both time and space are maileable – they can change within spacetime, but no matter how big or small one part is, THE TOTAL IS ALWAYS 100% - so TIME TRAVEL IS POSSIBLE, in fact, we’re ALL traveling through time right now !!!!!
Protostar Evolutions
Protostar Evolution in detail contains a random amount of interstellar gaseous matter, mainly hydrogen, containing traces of dusts (ices, carbon, rocks).
Interplanetary Travel
The planets are very far away. A spacecraft traveling at 60 mph a typical speed of a car on a highway – would take about 60 years to reach Mars. Fortunately, rockets travel much faster than this. The Voyager spacecraft sped from the Earth at 32000 MPH. But even at this speed, travel to the planets takes a long time. The Future space colonies will have to be self – sufficient, growing t...
The Future of NASA
Today man has started a striking and driven revamped space drive to prepare us to investigate revamped worlds, improve more creative mechanics, cultivate revamped commercial ventures, build our perceiving of the earth, unfold our presence in the earth's planetary group, and motivate the cutting edge of travellers. 
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.
Map of the Moon
The physical investigation of the Moon started when Luna 2, a space test started by the Soviet Union, made an effect on the surface of the Moon on September 14, 1959. Former to that the sole good to go method of investigation had been perception from Earth. The stroke of genius of the optical telescope realized the first jump in the value of lunar recognitions. Galileo Galilei is ordinarily...

In the ballpark of 30 group parts fly with the pathfinder and examine the shuttle for ha...
Saturn's Rings Explained
The rings of Saturn are the most far reaching planetary ring framework of any planet in the Earth's planetary group. They comprise of endless minor particles, running in size from micrometres to metres,that circle about Saturn. The ring particles are made just about truly of water ice, with a follow segment of rough material. There is still no agreement as to their mechanism of creation; certa...
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...

The Solar System comprises of the Sun and it is planetary framework of eight planets, their moons, and different non-stellar protests. It framed more or less 4.6 billion years back from the crumple of a titan atomic fog. The boundless larger part of the framework's mass is in the Sun, with the vast majority of the remaining mass held in the planets. The four more minor inward planets, Mercury...
Mars World Map
In 1659 Dutch astronomer Christian Huygens, using an early telescope, drew the first sketch of a surface feature on Mars, a dark patch know today as Syrtis Major. More than three centuries later the mars global Surveyor is charting the entire planet. Data beamed from the orbiting surveyor have rendered a detailed and true-color map of this seemingly most Earthlike of planets.
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.
