Science Neutron stars‚ second only to black holes and pints of Guinness as the densest objects in the Universe‚ may have liquid in their cores‚ observations of a dead star shrouded in the debris of a distant supernova suggest. Two separate teams of scientists say that a frictionless state of matter called a superfluid is the only reasonable explanation for temperature changes recently observed in the youngest known neutron star. “This the first direct evidence for superfluidity in neutron stars

The Hubble telescope is a telescope that takes pictures of the universe and has transformed the way scientists look at our universe. The Hubble telescope circles the Earth in 97 minutes at a speed of about 5 miles per second. The telescope has taken hundreds of thousands of fascinating pictures of our universe and all the amazing parts of it. The Hubble telescope was named after Edwin Hubble who had made some of the most important discoveries in astronomy. Hubble travels more then 150 million

Born in 1738‚ Fredrick William Herschel‚ as a young adult‚ he was interested in music and moved to England to excel at the oboe. During his lifetime‚ he composed 26 symphonies as well as several other shorter works. An introduction to astronomy and mathematics by his father turned out to be his new passion. A fascination with telescopes peaked his interest and‚ in 1774‚ he constructed his first large telescope. He would spend multiple hours a day polishing and grinding the mirrors used in the

“What I Learned this Semester about Big History” It is very interesting how you can get a long and sometimes controversial answer to a simple question‚ such as “where does coffee come from?” As we saw in the Bain film and read Big History article‚ one small thing or event is connected to people‚ places‚ and big events on the earth. In the Big History article explains how history is looked at “ from the Big Bang to the modernity.” In modern days we have coffee as part of our morning routine

@ A galaxy is a vast‚ gravitationally bound collection of billions of stars Their "friends" include nebulae‚ stellar remnants‚ planets and other smaller particles including the basic elements hydrogen and helium. Galaxies also consist of an important but poorly understood substance called dark matter. It is believed to surround every galaxy and accounts for much of its mass. STELLAR REMNANTS - Stellar Remnant is a collective term used to describe the stars that are left . DARK MATTER - dark

The Creation Of The Universe‚ The Earth‚ And Human Beings In the beginning there was only darkness. For many millions of years this darkness remained. There were no stars‚ no sun‚ and no earth. But one day something very special happened. The darkness created light. It was a very small amount of light but it was just enough. The light became the husband of the dark. After a long while both the light and the dark became bored. The light began to insult the dark and the light replied with equally

Solar Nebular Hypothesis The idea behind the Solar Nebular Hypothesis is that the solar system was condensed from an enormous cloud of hydrogen‚ helium‚ and a few other elements and rocks. Around five billion years this cloud of materials began to spin and contract together into a disk shape under their own gravitational forces. The particles started combined together‚ protoplanets‚ to eventually form planets. A great mass of the material eventually began to form together‚ protosun‚ and make

A black hole is an object with such a strong gravitational field that even light cannot escape from its surface. A black hole may be formed when a massive object (very big object) undergoes uncontrolled contraction (a collapse) because of the inward pull of its own gravity. We shall now describe how the black holes are formed from neutron stars after the supernova explosions of big stars. When a supernova explosion of a very massive star takes place‚ then the gaseous matter present in the outer shell

BACKGROUND Continental drift is a theory proposed by a scientist‚ Alfred Wegener in the twentieth century. The theory explained that all the continents was once joined as one‚ and through the course of millions of years‚ drifted apart from each other to form separate continents as we see it now. THEORY Before all the continents were separated‚ they existed as one supercontinent‚ Pangaea (Lovett‚ 2008)‚ surrounded by a super ocean‚ known as Panthalassa. Movement of continents can be compared to
