100 Million Stars in the Andromeda Galaxy



What stars compose the Andromeda galaxy? To better understand, a group of researchers studied the nearby spiral by composing the largest image ever taken with the Hubble Space Telescope. The result, called the Panchromatic Hubble Andromeda Treasury (PHAT), involved thousands of observations, hundreds of fields, spanned about a third of the galaxy, and resolved over 100 million stars. In the featured composite image, the central part of the galaxy is seen on the far left, while a blue spiral arm is prominent on the right. The brightest stars, scattered over the frame, are actually Milky Way foreground stars. The PHAT data is being analyzed to better understand where and how stars have formed in M31 in contrast to our Milky Way Galaxy, and to identify and characterize Andromeda's stellar clusters and obscuring dust.

To punish the Marsh Arabs who rebelled against his rule, Saddam Hussein drained the marshes where they lived in 1991, destroying the largest area of natural wetlands in the Middle East. The Marsh Arabs (Ma’dan) and their ancestors had lived in these rich wetlands for over 5,000 years. This was one of the most serious attacks on the natural environment in world history. In 2003, the dykes were broken but only 40% of the marshes were restored.

Hubble’s High-Definition Panoramic View of the Andromeda Galaxy



The largest NASA Hubble Space Telescope image ever assembled, this sweeping bird’s-eye view of a portion of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic next-door neighbor. Though the galaxy is over 2 million light-years away, the Hubble Space Telescope is powerful enough to resolve individual stars in a 61,000-light-year-long stretch of the galaxy’s pancake-shaped disk. It's like photographing a beach and resolving individual grains of sand. And there are lots of stars in this sweeping view -- over 100 million, with some of them in thousands of star clusters seen embedded in the disk. This ambitious photographic cartography of the Andromeda galaxy represents a new benchmark for precision studies of large spiral galaxies that dominate the universe's population of over 100 billion galaxies. Never before have astronomers been able to see individual stars inside an external spiral galaxy over such a large contiguous area. Most of the stars in the universe live inside such majestic star cities, and this is the first data that reveal populations of stars in context to their home galaxy. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy, Inc., in Washington. > More: Hubble's High-Definition Panoramic View of the Andromeda Galaxy Image Credit: NASA, ESA, J.

January 6th 1852: Louis Braille dies



On this day in 1852, the French educator Louis Braille died in Paris aged 43. Braille is best known for inventing the system of reading and writing used by blind people. He was born in a small French town in January 1809 and was himself blinded at a young age when, aged three, Braille suffered an injury to his eye from an awl he found in his father’s workshop. The boy lost the sight in both eyes due to the accident, but refused to give up on his education. He struggled at school, as even at the Royal Institution for Blind Youth in Paris - where he began attending when he was ten - the teachers just talked at the students. Braille found the school’s fourteen raised-letter books entirely inadequate and was desperate to find a better way to read. When Braille was twelve, a former soldier called Charles Barbier visited the school and demonstrated his ‘night writing’ code of raised dots and dashes for soldiers to communicate. The exceptionally gifted young Braille then modified Barbier’s system, using just six dots rather than twelve to make it quicker and easier to read. Poignantly, Braille created his own raised dot system using an awl, the same instrument that had blinded him. In 1829, when he was twenty, he published the first ever braille book. Braille continued to modify and improve the system, but unfortunately its brilliance was not recognised until after his death in 1852. It was in 1868, when the forerunners of the British Royal National Institute for the Blind took up the cause, that the system began to be taught and spread worldwide. Louis Braille’s invention is now used all around the world and has provided blind people everywhere with a tool to read books and public signs and to communicate independently.



"Access to communication in the widest sense is access to knowledge, and that is vitally important for us if we [the blind] are not to go on being despised or patronized by condescending sighted people. We do not need pity, nor do we need to be reminded we are vulnerable. We must be treated as equals – and communication is the way this can be brought about

- Louis Braille
