Known as "super-Earths" because they're larger than Earth but are thought to be rocky planets like our own, rather than gas giants.
Experts have been looking for planets around the star for about 20 years, but apart from a weak signal that has piqued their curiosity, they have been unable to find anything else. In addition, the star is unusually peaceful, which suggests that if it has a planet within its habitable zone, that world may have a greater chance of life being present than other worlds around the red dwarfs.
The global team - joined by Australian astronomers at the USQ, UNSW Sydney and Macquarie University- detected the system of planets orbiting the brightest red dwarf star in the night sky, Gliese 887.
"The planets are interior to, but close to the inner edge of, the liquid-water habitable zone", the researchers wrote in their study published in the journal Science.
Fellow USQ researcher and study co-author Professor Rob Wittenmyer said the star was also very stable.
They found that the star appeared to be orbited by planets that have orbits that would give them years of just 9.3 and 21.8 days on Earth. These two exoplanets (planets located outside of our solar system) have been named Gliese 887b and Gliese 887c, respectively. What is even more interesting is that these planets have a structure similar to that of our planet and are capable of hosting extraterrestrial life.
Express reports a group of worldwide astronomers detected the presence of a system made up of "super-Earth" exoplanets orbiting the red dwarf star Gliese 887, which is located 11 light-years away from Earth.
If the star was as active as our Sun, it is likely that a strong stellar wind - outflowing material which can erode a planet's atmosphere - would simply sweep away the planets' atmospheres. This means that the newly discovered planets may retain their atmospheres, or have thicker atmospheres than the Earth, and potentially host life, even though GJ887 receives more light than the Earth.
Also known as Gliese 887, GJ 887 and HD 217987, this red dwarf lies in the southern constellation of Piscis Austrinus.
Another interesting discovery that the scientists made was that Gliese 887's brightness is almost constant. The impressive results of this study have caught the attention of NASA, which has declared that the next-generation James Webb Space Telescope will target these interesting planets when it will be released in 2021.
Dr Sandra Jeffers, from the University of Göttingen and lead author of the study, said: "These planets will provide the best possibilities for more detailed studies, including the search for life outside our Solar System".
Their distance from their host star is much shorter than that of the Earth-Sun relationship.
Locust swarms spotted in multiple places in Gurugram
Speaking about the measures taken by the Haryana government, he said, "We are fully on alert, our districts have been alerted. The Gurugram administration has asked residents to make clanging noise by beating utensils to ward the locusts off.
