Earth Will Dead in 2.8 Billion Years





The biological and geological future of the Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at the Earth's surface, the rate of cooling of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.

Cassini space probe will see Saturn eclipse the sun on July 19



It discus about NASA’s Cassini spacecraft, now orbiting Saturn and weaving in and among its moons, will be aligned in such a way that Saturn will eclipse the sun as seen from the spacecraft. This simulated view from NASA’s Cassini spacecraft shows the expected positions of Saturn and Earth on July 19, 2013, around the time Cassini will take Earth’s picture. Cassini will be about 898 million miles (1.44 billion kilometers) away from Earth at the time. That distance is nearly 10 times the distance from the sun to Earth. Image credit: NASA/JPL-Caltech.

X-Ray in Astronomy



Astronomers study light from all across the electromagnetic spectrum to piece together the story of the universe.  X-ray astronomy looks at high energy, short wavelength light – over 40 times smaller than the shortest wavelength our eyes can detect.  This light, emitted by gas heated to millions of degrees, provides a glimpse into extreme environments like black holes, neutron stars, and colliding galaxies.

Closest Moon in 2013



Do you know what is Supermoon? Ya, I think you all know about this one. Supermoon is a new or full moon which occurs with the moon at or near (within 90% of) its closest approach to Earth in a given orbit. Earth, moon and sun are all in a line, with moon in its nearest approach to Earth. In 22-23 June 2013 is the closest moon with Earth for all of 2013. If you saw this supermoon last week, you would be amazed for what you see. The moon was so beautiful and looked so close.

NASA TELESCOPE



This is the new telescope in the universe. The large, new astronomical telescope, Atacama Large Millimeter Array, ALMA consists of 66 radio telescopes and is the largest and most ambitious ground-based telescope to date. It has just been completed in Chile and is now beginning observations. Although they are called radio telescopes it does not mean that they listen for sound – they observe radio waves, which are long wavelength electromagnetic radiation. That is to say light which is outside the visible spectrum. Long wavelength radiation is important in order to observe particular phenomena in the universe.

Unknown Facts about Mars



Do you know Mars? Ya, It’s a planet, one of planet in our solar system. Everyone knows about this planet generally. For the example, everyone knows Mars as Red Planet, right? Or they know that Mars is the fourth closest planet to the sun. They don’t know more specific about Mars. In this article, I will talk about some facts about mars that you don’t know before. You will get new information. Check this out guys.

Quasars



Quasars is a very energetic and distant active galactic nucleus. These mysterious starlike objects shine from the outermost limits of the universe, helping scientists learn about the earliest stages of existence. We’ve since learned that a quasar is actually a black hole at the center of a huge, distant galaxy. Perhaps more interesting, quasars give off 1,000 times more energy than the entire Milky Way galaxy.
