Crab Nebula is probably the most famous object in the night sky. It was portraited as an M1 in the famous catalog Messier. Those are the remains of the supernova, that could have been seen during the day almost 1000 years ago. Since then, it’s residues fascinating to both professionals and Home astronomers.
Thanks to modern technology we can obtain an actual view of the magnificent remains of that supernova. Observers of different institutions, lead by Thoams Martin and the Laval University, for the first time created a 3-dimensional image of the Nebula.
That’s important for more than one reason, it’s not like we are having a new cool picture to look at. The pictures include 3D types, they contain data and this data could be used for a better understanding of the object. A long therm argument is concentrated on what type of star was the Crab Nebula at the beginning. Astronomers concluded a long time ago the fact that the core of the star is made of Oxygen, Neon, and magnesium. They also found out a structure of the Nebula’s core that could say otherwise for that belief.
In the center of the Nebula, we could see a structure that looks like a honeycomb and the shape of a real human heart. In the models of “Electron-capture” with the capturing of the electron Supernova, the same as the one in the Crab Nebula’s structure and its formation, it’s unlikely that to be the cause of its formation.
Till now it didn’t have such a fundamental and credible alternative to the real composition. But if there is something, that scientists should answer with this question, is with data. And the data gathered from the team, lead by Dr. Martin, have a lot to say about it.
They are using Spectrometer SITELLE, which is part of the telescope Canada-Hawai-France, and its position in Hawai (when recently rained snow). With this extremely precise tool, the team managed to capture 300 000 specters on the whole Crab Nebula.
SITELLE is gathered data for many other comparable supernovas since it’s the purpose of working. Another interesting discovery from this preliminary analysis of data is the ejecting of at least two residues from a supernova creating a wide-scale ring structure, which also appears in the Crab Nebula.
All these images of rings and hearts make a great background for the upcoming Valentine’s day. Maybe with a gathering of more data, the image of one of the most famous objects in our night sky, could one day be on Valentine’s cards in the near future.
