As we cannot yet travel outside the solar system, we have to learn as much as we can about the stars by studying them at a distance. Astronomers can tell the brightness, color, and temperature of a star by analyzing the light it gives out.
By splitting starlight into its constituent colors, they can find out what the stars are made of and how fast they are moving.
Stars are so far away, we are not normally aware of their movement through space. But over time this movement, called proper motion, changes the shapes of constellations dramatically.
Astronomers can figure out a constellation’s past and future shape by precisely measuring the positions of its stars over several years.

The universe is expanding at an ever – increasing rate, with something that astronomers call dark energy appearing to push it apart faster than gravity can pull it together. Type la supernovas are stars that explodes with a predictable brightness. Light from distant supernovas locks dimmer and redder than expected, implying that the universe is expanding. The more distant the star, the fast...
If extraterrestrials were watching our TV shows, this is what they would be watching, depending on where they are in space. This concept is extremely interesting, because our TV shows are never lost, they are still being broadcasted in different areas of the universe. Waves travel nearly forever in space, unless an outside force acts on them.
Space messages tell about the biosphere, that includes the basic chemical compositions of the continents, oceans and atmosphere. The highest and lowest points of Earth and the surface strength of gravity are also listed in the space messages. Along with the relative sizes and ordering of the planets in our solar system, this message tells about the mass and radius of both our Sun and Jupiter. ...
It has been 50 years since the Russian pilot Yuri Gagarin has stepped onto the Moon in 1961. Since then more than 500 people have been launched into space in a variety of vessels.

The farthest away that humans have traveled so far was 248655 mi, which was achieved by the Apollo 13 astronauts ...
After Pluto was discovered in 1930, it was regarded as the ninth major planet, although it was soon found to be very different from the others. It is smaller than Earth’s Moon and follows an elongated, titled orbit. In the 1990’s astronomers began to discover small bodies similar to Pluto beyond Neptune. Some, such as Eris, were larger then Pluto. In 2006, astronomers decided to define a ne...
