article: They are the most recognisable shapes in the night sky, tracing distinctive patterns that have enabled astronomers to navigate the starscape above them for thousands of years. Yet for anyone staring at the heavens 98,000 year from now, the constellations could look very different indeed. Martin Vargic, a graphic designer from Slovakia, has created a chart that shows how the most famous of the constellations have changed from 50,000 BC to 100,000CE. Martin Vargic used satellite data to chart how the constellation stars have shifted and will change in the future . Using data collected by the European Space Agency on the gradually shifting position of stars, he has estimated how the constellations will change between. The results suggest that many of the most distinctive constellations will become almost unrecognisable in the future and some may need to be renamed entirely. Stars generate sounds on their surface in an unexpected way, according to new experimental evidence. Of course, as space is a vacuum it is impossible to hear sound in space, but the discovery reveals a new way that fluids can interact to produce a sound - one with an extremely high frequency. The researchers found that, when material - dust or gas from nearby - falls onto a star, it can produce an extremely high pitched sound in the plasma. The researchers said the phenomenon is 'more common in younger stars' that are still accumulating material from their surroundings. It would be less common in more mature stars, like our sun. The Big Dipper, for example, will change from looking like a plough to something that looks more like duck, while the proud form of Leo will mutate into an unrecognisable shape. Orion, named after the hunter in Greek mythology, will lose his head and the Crux will become little more than two parallel lines similar to an equals sign. Mr Vargic's chart also shows how some of the more abstract constellations, like Cassiopeia, were almost unrecognisable further back in human history when our ancestors were still living in caves. Lyra would also have faced completely the wrong way 52,000 years ago. Mr Vargic said: 'On a short timescale, stars appear to maintain nearly fixed positions in relation to each other, long term observations show that all stars indeed move and all constellations gradually change over time.' Astronomers have been recording the position of the stars since the Ancient Greeks, who believed the Earth was at the centre of the universe due to the apparent unchanging nature of the stars. This animation shows how the constellation Leo changed from 50,000BC to what it will look like in 100,000CE . The constellations were initially named after real life objects and mythical figures they appeared to represent and that tradition has continued. There are now 88 officially recognised constellations. In some cases ancient travelers used the constellations to help find their way at night. Now, using sophisticated observations from space telescopes like Hubble and the European Space Agency's Hipparcos satellite, scientists have been able to watch the movement of the stars. This has allowed astronomers to predict the position of the stars thousands of years into the future. Mr Vargic's chart shows how some of the constellations will become probably need to be renamed. From left to right the image above shows how they changed from 50,000BC, 2,000AD, 50,000CE and 100,000CE . This animation shows how Leo has changed since 50,000BC and how unrecognisable it will be in 100,000CE . Mr Vargic used data from the four year long Hipparcos satellite mission, which was launched in 1989, to collect data on the position of the stars. While there are some celestial objects that move across the sky quite regularly - such as the planets and the Moon - most of the stars vary little in relation to each other. Obviously their position in the sky changes as the Earth itself spins on its axis and moves around the Sun, the constellations have remained appeared constant through out human history. This animation show the changing face of the constellation Cassiopia from 50,000BC to 100,000CE . This animation shows how Orion's distinctive shape will change to become headless in the next 98,000 years . In fact many stars, including our own sun, are moving through space at thousands of miles per hour. However the vast distances between the Earth and the stars makes them appear static and those that are closer appear to move more. Dr Marek Kukula, public astronomer at the Royal Observatory in Greenwich, said: 'In art and poetry the idea of the stars being fixed and eternal is a strong theme. 'However, we now know our solar system is moving through the Milky Way and other stars have their own particular paths. 'The constellations shapes already look a bid dodgy when trying to see the patterns in them, but in the future we may need to find some different names for them altogether.' The Big Dipper could eventually start to look more like the Big Duck over the next 98,000 years . This animation shows how the Crux will shift from being a distinct crucifix to two parallel lines by 100,000CE .
