The stars with the smallest orbits were discovered

Strange discovery in space!

Our Sun, actually a star, is a loner, but most of the stars in our galaxy are in a long-term association with another star. The same is true for two stars located about 3,000 light-years from Earth. They are unique in that they orbit each other every 51 minutes, making them the shortest known orbits. “Imagine if the moon crossed the sky ten times a night. We’re talking about that kind of speed,” said Kevin Burdge, an astronomer at the Massachusetts Institute of Technology and lead author of the study published in the science journal Nature. IFL Science.

This is not the only thing that makes them special. The fact that they are so close to each other means that one swallows the other. A white dwarf, essentially the hot, compact core of a former star, eats material from the body of its celestial partner, a star similar to our Sun. Over millions of years, the distance between these two stars has shrunk to the point where the Moon is closer to each other than Earth.

J1813+4251, the largest star in the ZTF system, has the same temperature as the Sun, but has shrunk to 10% of its diameter, reaching the size of Jupiter. The white dwarf has 56% the mass of our Sun, but is denser, 1.5 times the diameter of Earth. Although the white dwarf is nearing the end of its life, the cannibalization of its partner of the last 8 billion years prevents it from living peacefully in old age.

Australia wants to grow plants on the moon by 2025

Australian scientists are reportedly planning to grow plants on the moon by 2025 in a mission unveiled Friday aimed at developing a colony on Earth’s natural moon. The Daily Star. “This project is the first step toward planting plants for the production of food, medicine, and oxygen, all of which are critical to establishing human life on the Moon,” the researchers said in a statement.

Brett Williams, a biologist at the Queensland University of Technology, said the seeds would be delivered by the Beresheet 2 probe, a private Israeli mission. Once in the soil after the salinity, the seeds are soaked in a closed chamber and scientists observe for any signs of germination.

Plant types are selected based on their ability to withstand extreme weather conditions, but also their germination rate. In addition to laying the groundwork for human life on the Moon, Australian National Professor Caitlin Byrt suggested the mission could serve as a laboratory for finding solutions to food security issues amid global warming. University. “If we can create a system to grow plants on the moon, we can create a system to grow food in the harshest environments on Earth,” she said in a statement. The project is led by the Lunaria One organization, which includes Australian and Israeli scientists.
