Scientists observed one of the smallest black holes ever observed last year. In addition, an object just 1500 light-years from Earth and another object thought to be a black hole or high-mass neutron star 12,000 light-years away were also discovered.
According to the reports published in the science journal Science News, it was noticed that there were some inaccuracies in the results of the observations made last year. So what are the new discoveries that scientists have noticed in this field? Let’s take a look at the details of the news together.
NASA’s first space tourism mission to the ISS, Ax-1, has been delayed for the fifth time!
NASA’s first space tourism mission to the ISS turned into a snake story. The date of the mission has been postponed again.
It has been noticed that black holes are binary star systems!
According to Science News reports, scientists combined the data from the observations and found that the Giraffe and the Unicorn black holes discovered last year are actually double star system they realized it was. The main issue that stood out in the data was the observation of stars at an unprecedented evolutionary stage.
A binary star system, as the name suggests, consists of two stars orbiting each other’s central masses. Stars go through the main sequence, subgiant, red giant, helium main sequence and white dwarf phases. The star finally turns into a black hole or neutron star, depending on its mass.
In binary star systems; It was noticed that the star in the sub-giant phase was absorbing some material from the star in the red giant phase due to its gravity. It was observed that the star in the sub-giant phase rotates faster in this way. However, this relationship between star systems is not among the first observed events. Last year, scientists noticed tiny Neptune planets that lost material in two star systems and turned into Super-Earth planets.
