Scientists are keenly hoping to observe a black hole closely and take clear pictures of it in the year 2017. For all those who want to know what exactly a black hole is, according to a definition on posted on NASA’s website,
it is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
A team of scientists is expecting to use a new computer algorithm and various other equipment in order to take the first picture of a black hole’s event horizon in the next year. It is said, that the picture will be taken by a project called Event Horizon Telescope, which is a network of nine radio telescopes strategically placed around the world (in countries like Mexico, Chile etc.)
The scientists claim that the project is now almost ready to put to use, all the elements are in place.
A team member Feryal Ozel, also a professor of Astronomy and Astrophysics at the University of Arizona, is said to comment on the progress and told BBC News,
We’re almost there, the phasing in of the instruments has been done, the receivers are in place and the theoretical work has been done.
Feryal Ozel is also reported to have said there are a few challenges which they need to overcome in order to take a picture of a black hole which is known to be extremely small in the galaxy. She also says, that what the team is hoping to achieve is to record a full array observation of a black hole in beginning of the year 2017.
A black hole is said to exist in the center of our own galaxy, in the middle of Milky way. However, it is relatively small in size (17 times size of our Sun), therefore difficult to spot with all the hindrances. The huge clouds of dust and gas surrounding the black hole is what makes it even more difficult to spot the black hole in our galaxy.
Hence, the new project which is designed by incorporating a complex algorithm in the nine telescopes, will be used to observe closely and record the black hole activity in our galaxy. The algorithm will also be demonstrated at the Computer Vision and Pattern Recognition conference this month. Intense work and theoretical calculations have been made while deciding which wavelengths to settle on in order to get through the clouds and dust which surrounds the black hole. Scientists have decided on a specific wavelength of 1.3 mm.
