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.

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.

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.

Diagram of the Space Station Life Support System
This diagram shows how astronauts live on the space station. Everything is attempted to be recovered on the space station. The urine that astronauts dispense from their bodies is reused as water. Waste water is then reused to create oxygen. Co2 is removed through overboard venting. It's amazing how much everything is reused on board.

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 !!!!!

Lunar Eclipses Explained
A eclipse occurs when the Moon passes straight at the rear of the Earth into its umbra (shadow). This will happen only once the sun's rays, Earth, and Celestial satellite are aligned specifically, or extremely closely thus, using the World in the middle. Therefore, the eclipse can only occur the night time of your full-of-the-moon. The sort and also period of a great eclipse depend upon the Mo...

How Far are the Stars
Until 1838, Astronomers had little idea of the true size of the Universe.

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...

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.

Farside of the Moon
The farside of the moon is always turned away from the Earth. Its appearance remained a mystery until 1959, when the Russian spacecraft Luna 3 was able to travel behind the Moon and send back the first photographs. Although the farside looks similar to the moon’s nearside, there are obvious differences. It has few maria, because the lunar crust is thicker than on the nearside, making it dif...

Explaining Gravitational Lensing
Light always leaves from a young, star forming blue galaxy near the edge of the visible universe. Some of the light passes through a large cluster of galaxies and surrounding dark matter, directly in the line of sight between earth and the distant galaxy. The dark matter’s gravity acts like a lens, bending the incoming light.
