Scientists confirm existence of Proxima B; could there be signs of life on this planet?

universe is a vast place full of mystery, for years, researchers have been trying to figure different planets, solar systems and most importantly, if re is life or than that on our planet. So as search for life continues, scientists have confirmed that Proxima B is definitely present at Proxima Centauri.

New Earth Proxima b could be our big hope

Proxima Centauri is closest star to our solar system’s sun. Reportedly, Proxima b sits 4.2 light-years away from sun and has a mass 1.17 times mass of Earth. planet orbits star Proxima Centauri in eleven days. planet was first discovered in year 2016 using High Accuracy Radial Velocity Planet Searcher spectrograph, which is based in Chile.

More information regarding same has come through using Swiss manufactured ESPRESSO spectrograph. Researchers have told a media portal that Proxima b is about 20 times closer to its star Proxima Centauri compared to distance between Earth and Sun. However, amount of energy that Proxima b and Earth receive from ir respective stars are akin.

Due to this reason, it is believed that surface temperature of Earth and Proxima b would also be similar. This furr could mean that re is hope of water being present on Proxima b, which furr implies that re could be life on planet. Francesco Pepe, a professor in Astromy Department in UNIGE's Faculty of Science and leader of ESPRESSO spoke to a media portal on matter.

He told portal that y were already pleased with performance of HARPS which discovered hundreds of exoplanets over last 17 years. He furr added that y have been happy that ESPRESSO could produce even better measurements. Francesco Pepe furr said it is gratifying and just rewarding for teamwork lasting nearly 10 years.

However, re is some potentially bad news regarding possibility of life on Proxima b. Scientists have said that Proxima Centauri tends to radiate X-rays towards planets near it, and rays are 400 times more than what sun sends towards Earth. refore, a lot depends on atmosphere around Proxima b and wher it is able to shield surface from se rays.
