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.

Exploring the Moon
People have dreamed of exploring the Moon for hundreds of years. The United States and Russia made the dream a reality in the middle of the 20th century. In 1959, Luna 1- the first spacecraft to leave the Earth’s gravity – was launched toward the Moon. A decade of intense space activity followed as Russian and American probes, robots, and crewed craft were sent to investigate and land on the l...

Star Lifecycles
Stellar advancement is the methodology by which a star experiences an arrangement of radical updates around its lifetime. Hinging on the mass of the star, this lifetime extends from just a few million years for the most gigantic to trillions of years for the slightest huge, which is impressively longer than the time period characterized by the universe. All stars are born from falling mists of...

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.

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...

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.

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.
