Astronomers have discovered a new cosmic structure that may hold an alarming number of galaxies, stars and planets,media BGR reported. The structure, now known as the South Pole Wall, is located in an area obscured by our Milky Way. The discovery was made using data showing the motion of galaxies in a space region visible from Earth.
This is a huge collection of galaxies, about 1.4 billion light-years in diameter. It contains countless stars and planets, and it remains hidden behind our Milky Way until cosmologists come up with a solution. When we peer into space, many parts of the sky are unobstructed, but if we look in the direction of our own galaxy, the light of many stars and other matter will block most of our view of that space region. So the researchers came up with a different way to plot things they couldn’t see.
Instead of trying to directly observe the region, they used previous survey data to map the motion of distant galaxies they could see. They took into account the speed at which galaxies were far from Earth and how gravity from other directions affected them. After compressing the massive amount of data, the resulting map shows a huge collection of mass, one of the ten most largest cosmic structures ever detected.
As LiveScience reported, the researchers estimate that the “Antarctic wall” contains the mass of about 100 million suns. The researchers say there may be more mass there, and they have not yet been able to detect and plot. The really interesting part is that the researchers were unable to determine what the giant sphere contained. It’s likely that there are hundreds of thousands of galaxies because of its sheer size, but because dark matter — which does nisse, still exerts gravity — is thought to be richer than ordinary matter in space, there may also be a lot of dark matter present.
