J0624–6948 – Lone star between galaxies!
Recommended for Preparatory Grades
Not far from the Large Nebular Cloud, which is a satellite galaxy that orbits the Milky Way, scientists have found a mysterious and very neat circle in space that is emitting radio waves. It is called J0624–6948. This is the first time that astronomers think they’ve found proof that one of these lone stars between galaxies has exploded.
If the universe isn’t chaotic, then it isn’t the universe. In galaxies, which are separated by vast distances, a large number of the stars are immersed. Intergalactic space, the region between galaxies, is sparsely populated, but it is far from empty, as evidenced by the presence of a few single stars.
What are Odd Radio Circles (ORC)?
Odd Radio Circles are radio-emitting space circles.
The curious case of Odd Radio Circles!
Experts at first thought the star (“J0624–6948”) to be an ORC however after additional observations, they felt the object is more likely to be something different. The Australian Square Kilometre Array Pathfinder (ASKAP) in Australia was the first radio telescope to discover ORCs. Large and far away, these objects appeared to have a galaxy at their centre, among other distinguishing features.
Scientists now believe that the ORCs are the result of an energetic process in those central galaxies, but the exact nature of that process is unknown to them at this time. ORCs may in fact be spheres, according to a number of scientists. The fact that they appear as rings is due to the fact that the emission intensity is higher along the edges of the objects from the researchers’ viewpoint.
Our readers could read the discovery in a research paper published in the Monthly Notices of the Royal Astronomical Society.
Intergalactic Supernova Remanant!
Scientists believe the object (“J0624–6948”) is most likely the remains of an exploded star between galaxies. In addition, this object has in fact expanded into the intergalactic environment. This is extremely interesting for scientists because they rarely find such objects in intergalactic space. As per experts, the object is about 2,200 to 7,100 years old. Wow!
