According to reports, astronomers have found evidence of an earth-like planet outside the solar system of earth, which means that extraterrestrial life may exist. In 2014, scientists from the United States dismissed planet Gliese 581d. At that time, they said that the planet was just magnetic bursts from stars.

But a new study conducted by British astronomers unveiled that the previous data analysis of Gliese 581d and Gliese 581g was not enough. The study published by Queen Mary University and the University of Hertfordshire identified Gliese 581d as a planet. According to the researchers, they have found evidence that the planet could support life. The conditions on the planet are not too cold or hot for water to form. But, the study also indicated that it could be too toxic for humans to exist with its thicker air.

According to reports, Gliese 581d is the first planet that was found outside earth's solar system. Dr. Guillem Anglada-Escudé, lead author of the study, said, "The existence or not of GJ 581d is significant because it was the first Earth-like planet discovered in the 'Goldilocks'-zone around another star and it is a benchmark case for the Doppler technique".

The author also said that there are several questions about the data that the researchers have interpreted, but the researchers are confident that GJ 581d has been in orbit around Gliese 581 all along.

As per the reports, the researchers had used a spectrometer to spot the planet. According to Anglada-Escudé, the technique that they used had made it easier for them to identify larger planets than smaller ones in the past.

Earlier, scientists had abandoned mysterious signals pointing to an earth-like planet about 20 million light years away. According to them, it was caused by starspots and ignored it.
