Only recently, astronomers were able to get the first photos of the black hole, and now you need to achieve the next goal – to get better quality images. Thus, it will be possible to test Einstein’s General Relativity. Specialists from the Netherlands University of Nijmegen, ESA and other scientific organizations presented a new concept of obtaining clear frames of black holes, created on the basis of the use of powerful space telescopes.
The essence of the technique, called the Event Horizon Imager (EHI), is to install 2-3 satellites for observing black holes in a circular orbit around the Earth. In their study, scientists have shown images of black holes, which were obtained through modeling. So, to some extent, imagine the quality of future high-resolution photographs taken by EHI.
“If you use satellites, rather than ground-based telescopes, then there are a number of advantages. In space, opportunities are open for observations at higher frequencies, which are no longer suitable for observations from the Earth, because they are severely constrained by the atmosphere. In addition, space allows you to install spacecraft at a fairly large distance from each other. Thus, we can get footage with a resolution of more than 5 times greater than that of the EHT telescope, ”said Frick Roelofs, who is the main author of this study.
There is also an important point concerning the transfer of data. For example, the data obtained by the ground telescope EHT, are delivered to the analytical centers on hard drives on board airliners. This method is not suitable for data from space telescopes, so you can use a laser system to transfer data during primary processing on the satellites themselves directly in space.
The study is published on the pages of the popular scientific publication Astronomy & Astrophysics.
