A neutron star is that I was looking for more than 30 years may have been detected

The densest objects in the Universe — neutron star — the mysterious quanta collapse into the dark — . However, this metamorphosis is preceded by the phenomenon of massive stars — supernova. So, within 30 years, scientists hunted for the most famous supernovae in recent history. On 23 February 1987, astronomers with awe like a star exploded in a neighboring galaxy — that was the closest to our planet is a supernova explosion for the last 400 years. Both professionals and Amateur astronomers around the world immediately sent their telescopes for a dying star, waiting to see the birth of a new object — neutron star. But their search came to no avail, leaving experts frustrated and puzzled. Only recently, it was reported that astronomers were able to detect clear evidence of the "missing" neutron star, which is hidden in a still-cooling stellar debris from a supernova explosion. This gives scientists a unique opportunity to study the processes that occurred before and after the catastrophic destruction of the star.
Exploring history
In an article published in the journal , the team led by Phil Cigana from Cardiff University in the UK, looked into the Stardust to see a neutron star. One of the key obstacles to the study of supernova, called SN 1987A, is that she's left behind a huge veil of dust, representing approximately half of the mass of our Sun, hiding the place where once was a star. But by analyzing the historical data for 2015 is collected by the ALMA telescope in Chile, the team found the emissions of dust, indicating the presence of something hidden inside.
The Supernova SN 1987A, located in 163 thousand light-years away in the dwarf galaxy Large Magellanic Cloud. The end results of a supernova explosion are the most dense of the known astrophysical objects: neutron stars, which compress several solar masses into a ball the size of a city, and the ejected material expands in a meandering around, majestic . SN 1987A — is no exception. So around it you can see the bright and beautiful of an eccentric ring of dust that glow from the pulsating shock waves. In addition, SN 1987A is unique in its proximity to Land. Before the explosion experts have never watched a star-the progenitor of so much detail. Before this supernova became famous, astronomers knew that its mass is about 20 times the mass of our Sun and this size is likely to lead to the formation of the neutron star. However, the lack of direct detection of the object, despite attempts to see it using the world's best telescopes, has led some researchers to think about how, not wrong, whether theoretical models of supernovas, and have been on the vastness of space of some other process.

How to see the hidden star?
Not being able to see a neutron star directly in their karanopadhi clusters , no one can prove that this object — and not a Mirage of thick dust. Astronomers hope that in the coming years and decades, the dust will begin to disperse, allowing them for the first time to look into the center, but even that remains uncertain. The researchers plan to continue observing the object SN 1987A in 2020 with the help of a space telescope . By the way, recently we told you that the supernova collapsed into a black hole right in front of his lens. Despite the fact that to see a neutron star so far no one has hobby of SN 1987A are unlikely to soon come to naught. Note that today scientists observe a large number of supernova explosions that occur every year, very far from Earth. While SN 1987A is the only supernova that we see in real-time. So let's hope that researchers can finally get lucky.
