A dying star, also known as a white dwarf, killed the planets he was surrounded by! For perspective, think of our Sun and its planets!
A dying star has destroyed an entire planetary system, scientists reveal. Called G238-44, this white dwarf is altering an entire planetary system by consuming metallic and icy rock material. This cosmic phenomenon known as cosmic cannibalism has been first observed with the help of archival data from the Hubble Space Telescope and other NASA observatories. Astronomers gathered the findings from the analysis of material captured by the atmosphere of the white dwarf. A white dwarf is usually very dense and the size of a planet. It forms when a low-mass star depletes most of its nuclear fuel and then only a white dwarf remains.
Ted Johnson, principal investigator and graduate of the University of California, Los Angeles (UCLA), said in a press release: “We have never seen these two types of objects accumulate in a white dwarf at the same time. these white dwarfs, we hope to gain a better understanding of the planetary systems that are still intact. “

“Life as we know it requires a rocky planet covered with a variety of elements such as carbon, nitrogen, and oxygen,” shared Benjamin Zuckerman, co-author of the study. He added that the abundance of elements seen in the white dwarf looks like a rocky parent body rich in volatiles. He called it “the first example we found among the studies of hundreds of white dwarfs.”
The findings also show that our Sun could go through this process and become a red giant before swallowing the nearby planets in about five billion years. It will lose its outer layers, forming a “nebula.” Only a pitiful shell of its former glory will remain: a white dwarf.
