The Universe is not a chaotic free-for-all. Most of the stars are in the same place, but separated by vast distances.
There are occasional lone stars in the space between the galaxies and intergalactic space.
Astronomers think they have found evidence of the death of a rogue star. There is a satellite galaxy in the vicinity of the Large Magellanic Cloud and it has been detected hanging in space.
There is a reason that it sounds familiar. Astronomers have been perplexed by several mysterious, radio-emitting space circles.
The similarity was not lost on astronomer Miroslav Filipovic from the University of Western Sydney in Australia.
He says that when they first discovered the object, they thought it was another ORC.
ORCs were first discovered by using a radio telescope in Australia. The objects seemed to be huge and distant, with several defining characteristics, including a galaxy in the dead center.
The ORCs are thought to be the result of an energetic process in the central galaxies.
It is likely that ORCs are spheres. There is a greater density of emission around the edges of the rings because of their perspective.
There is a location of J0624 The report was written by Filippovic et al.
There are a few differences between the two. The lack of an obvious central galaxy is a big one, but not decisive on its own. The apparent size of J0624 is larger than the other ORCs and the radio emission is flatter.
A range of possibilities that might result in an object that resembles their observations was considered by the team. There were jets from a distant active black hole, as well as a much larger ORC, which came from a star near the galactic center.
The most consistent scenario was the one that stood out.
The most plausible explanation is that the object is an intergalactic Supernova Remnant due to an exploded star that resided in the Large Magellanic Cloud outskirts that had undergone a single-degenerate type Ia supernova.
The remnant of a supernova that has expanded into a rarefied, intergalactic environment is what we may have found. Our estimates show that the age is between 2,200 and 7,100 years old.
It wouldn't be the first time that a supernova remnant would be beautifully circular. The eye-shaped object SN 1987A in the Large Magellenic Cloud is one of a few similar examples.
If the scientists are correct, J0624 would be the first intergalactic supernova remnant ever identified. The team says that an association with the Large Magellanic Cloud would make J0624 around 155 light-years across.
Follow-up observations can help resolve uncertainties. More observations with instruments such as ASKAP and its South African counterpart could help identify more peculiar radio circles in the sky.
Finding more will give us a complete picture of their range and diversity, which will give us a better chance of figuring out what they are.
New radio telescopes can pick up a range of spherical objects.
