Scientists Identify The Only Species That Will Survive Until The Sun Dies
Water bear. Coloured scanning electron micrograph (SEM) of a water bear (Paramacrobiotus craterlaki) in moss. Water bears (or tardigrades) are tiny invertebrates that live in aquatic and semi-aquatic habitats such as lichen and damp moss. Paramacrobiotus craterlaki is a carnivorous species that feeds on nematodes and rotifers. Water bears are found throughout the world, including regions of extreme temperature, such as hot springs, and extreme pressure, such as deep underwater. They can also survive the high levels of radiation and vacuum of space. Magnification: x330 when printed at 10 centimetres wide.

Scientists Identify The Only Species That Will Survive Until The Sun Dies

The scientists took three potential cataclysmic events into consideration while conducting their research, which included a large asteroid impact, and exploding stars in the form of supernovae or gamma ray bursts.

“It seems that life, once it gets going, is hard to wipe out entirely,” Dr. David Sloan said. “Huge numbers of species or even entire genera may become extinct, but life as a whole will go on.”

Dr. Alves Batista of the University of Oxford stated that the existence of the tardigrade doesn’t just prove how life on Earth can continue long after our species, but it also gives hope for the search for extraterrestrial life.

“Tardigrades are as close to indestructible as it gets on Earth, but it is possible that there are other resilient species examples in the universe,” Dr. Alves Batista mentioned.
