The supernova remnant looks like a dandelion in the animation; check this out!

In a new study published in the scientific journal The Astrophysical Journal Letters, a group of researchers from the California Institute of Technology (Caltech) found Observations of a supernova remnant in the process of expansion.

With data collected by the Keck Cosmic Web Imager (KCWI) instrument at the WM Keck Observatory in Hawaii, the team was able to map the expansion in a 3D animation.

The information shows: After the supernova explosion, the remnants began to form filaments, giving the remnant the appearance of a dandelion. – even the authors note the similarity.

Examining the supernova remnant, This zodiac sign, called Pa 30, can give important information about your past and the events that brought you to this stage. It’s no surprise that 3D mapping is so important, as it allows scientists to observe the cosmic object in greater detail.

“A standard image of the supernova remnant would resemble a still photograph of a fireworks display. KCWI gives us something more like a ‘movie,’ because we can measure the movement of the embers of the explosion as the center of the explosion emerges from the explosion,” said Christopher Martin, Caltech professor of physics and KCWI team leader.

Dandelion looking supernova

Currently scientific understanding is that Pa 30 may be a remnant of the SN 1181 supernova observed by Chinese astronomers in August 1181. The remnant itself was discovered by amateur astronomer Dana Patchick, and scientists have devoted themselves to studying it ever since. For more information on the history of SN 1181, see here.

Based on the research, scientists suggest that SN 1181 may have resulted from a white dwarf that exploded after a less intense thermonuclear process than ordinary supernovae. Because there was a weaker explosion called an Iax type supernova S.Its ruins formed Pa 30 and gave it the beautiful appearance we can see in the pictures.

Although there is no definitive confirmation of the connection between Pa 30 and SN 1181, scientists say the data points to such a connection.

“We found that the material in the filaments expanded ballistically. This means that the material has not slowed or accelerated since the explosion. Looking back from the measured velocities, you can pinpoint the location of the explosion almost exactly to the year 1181,” said paper leader Tim Cunningham.
