Found brilliant red squares in the universe

Astronomers have been able to capture the most brilliant and symmetrical cosmic object, located only 5,000 light-years from our galaxy. This object, named by astronomers as a red square, could help decipher a mystery over the past 20 years.

"It's like a gemstone," said Dr. Peter Tuthill, from the University of Sydney and colleagues. "Everything is amazingly good."

Tuthill and colleagues found this red square around a star in the constellation Serpens. In essence, it is a dusty cloud shaped like an hourglass (called the bipolar nebula), with a cross-section showing two cones that lie atop each other. This cloud of dust and gas shines brightly thanks to its central star.

More important than beauty, Tuthill said the object could help explain the mystery of the past 20 years, related to the famous star explosion called Supernova 1987A.

Supernovae are exploding stars, and Supernova 1987A is the only thing recorded on camera. The side photo shows this booming star surrounded by two partially overlapping circles of gas and dust. Scientists do not understand why there are such circles, and this question remains to this day.

Tuthill said these rings must have existed before the star exploded, and the light that the star emitted had illuminated the rings (previously in the dark).

Now, in this new discovery, Tuthill thinks that the above circles are of a nebula, like the red square found. To test his hypothesis, he modeled three-dimensional red square nebula and turned it to see what it would look like in a two-dimensional perspective from different angles.

Tuthill discovered that at some angles, the red square nebula also gave a structure like two overlapping circles in the image of Supernova 1987A."It is possible that the exploding star created Supernova 1987A actually has a nebula surrounded, and is similar to a red square," he said. However, he was not sure whether the star at the center of the red square was about to explode.
