Leading scientists from NASA (US Aeronautics and Space Administration) affirm that humanity is gradually moving towards discovering alien life.
“We are gradually having more signs of extraterrestrial life and there will be evidence to confirm this in about 20-30 years,” Ellen Stofan, NASA’s leading expert, declared on April 7 in a discussion on the topic of searching for alien life.
NBC news agency (USA) said former astronaut John Grunsfeld, who is assisting NASA’s board of directors, also shares Stofan’s opinion. He also predicted that signs of extraterrestrial life may soon be found in the solar system and beyond.
“Recent discoveries show that the solar system, or more broadly the Milky Way galaxy, has an environment that supports life,” Grunsfeld said.
Water can be frozen under the shells of Jupiter’s satellites (including Europa and Ganymede), or Saturn’s satellite (Enceladus), this space expert said. On Mars, dark streaks observed on the planet’s surface are believed to be traces left behind by salt water. Thus, in the ancient past, it is possible that most of Mars was covered by ocean.
In addition, recently, the Mars rover Curiosity discovered carbon compounds containing organic molecules and “fixed” Nitro molecules, which are essential ingredients for life on Earth. land.
Going further, according to NASA observations from the Kepler space telescope, scientists think that nearly every star around the host planets, such as Mars, Saturn and Jupiter, has somewhere can live. From the Kepler telescope, the rocky environments of Earth and Mars are probably more common in the galaxy than the planets.
