YOUNG CHRONICLE November 21st , 2014 What Are Hubble's Most Important Discoveries? Contd. from Page 3 Hubble pictures have helped scientists guess the age and size of the universe. Scientists think the universe is about 13 or 14 billion years old. Hubble has also helped scientists understand how planets and galaxies form. A picture called ‘Hubble Ultra Deep Field’ shows the farthest galaxies ever seen. Hubble has spotted black holes. When a Star Dies, a Black Hole is formed. Black holes suck in everything around them, including light. Hubble has also helped to discover dark energy. Dark energy is a strange force that causes the universe to expand faster and faster as time goes on. And Hubble has helped scientists learn more about explosions that occur when huge stars die. Where do the colours in Hubble Pictures Come From? Hubble pictures start out as shades of black and white. Colours are then added to the pictures. colours can help show how an object might look to the human eye. Colours can also be used to point out an important detail in the picture. Or they can help to show details that the human eye wouldn't see. Fun Facts • • • • • • • Hubble is the length of a large school bus. It weighs as much as two adult elephants. Hubble travels around Earth at about 5 miles per second. The Hubble Space Telescope makes one orbit around Earth every 97 minutes. It travels 353 miles (569 km) above the Earth. The Hubble Telescope transmits about 120 gigabytes of data every week. It receives its energy from the sun through two 25-foot solar panels. There have been five astronaut servicing missions to Hubble: 1993, 1997, 1999, 2002 and 2009. The Hubble Telescope is able to lock onto an object that it is photographing. This allows it to remain steady in order to produce a near- ROHIT SHARMA’S CRICKET RECORDS Rohit's 264 is now the highest individual  score in ODI cricket. The previous record,  also held by an Indian, belonged to  Virender Sehwag, who struck 219 against  West Indies on December 8, 2011 in  Indore.  This was also the highest score in ODI  cricket ‐ men and women. The previous  record was held by Australia's Belinda  Clark, who scored an unbeaten 229  against Denmark in Mumbai on  December 16, 1997.   This is the second highest score in any  List A match, worldwide. The record is  held by Ali Brown, who scored 268 for  Surrey against Glamorgan at The Oval in  2002.  Rohit struck an astounding 33 fours and  nine sixes during the course of his knock ‐  a total of 186 runs in boundaries, also an  ODI world record. Shane Watson's 150  runs in boundaries for Australia, against  Bangladesh in Mirpur in 2011 was the  previous highest.   Page 6 21/11/14 The 33‐four tally also surpassed the  ODI record for the highest number of  fours in an innings. 25 was the  previous highest ‐ a record jointly held  by Tendulkar and Sehwag.
