Meanwhile, Dr. David Clements, astrophysicist at Imperial College London, said: 'This discovery does not mean that life exists on Enceladus, but it is a step on the way to that result'.
The evidence was collected by NASA's Cassini spacecraft, which has been examining Saturn and its satellites since 2004, providing Earth-bound researchers with important data.
Cassini has detected hydrogen molecules in vapor plumes emanating from cracks in the surface of Enceladus, a small ocean moon coated in a thick layer of ice, the USA space agency said.

The necessary ingredients for life as we know it include liquid water, energy sources and chemicals such as carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. The finding adds to the idea that the moon might harbor life in its subsurface ocean, as microbes could dine on the gas, along with carbon dioxide dissolved in the water to create energy, through a process known as methanogenesis.
Illinois woman rescued after falling into crevice in Arizona
A 70-year-old woman survived a 50-foot fall into a deep crack near the Grand Canyon Skywalk Wednesday afternoon. She reported falling a few more inches each time she took a deep breath, officials said.
"It could be a potential source for energy from any microbes", Fox News quoted Linda Spilker, Cassini project scientist at NASA's Jet Propulsion Laboratory in Pasadena, California.
NASA's new discoveries stem from the Hubble space telescope and the Cassini probe, which is scheduled to commit suicide this summer in the clouds of Saturn.
On Earth, where we find water, we find life, so that's where we like to look for life in space, too.
"It's another great day of science", Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate, told reporters.
The paper by researchers with the Cassini mission, published Thursday in Science magazine, says that the hydrogen gas - which could potentially provide a source of chemical energy for the existence of life - is found in Enceladus' frozen ocean.
Mignolet urges Liverpool to up their game
With time running out, the hosts had a corner and Foster was ushered forward, only for Liverpool to clear the ball. It was flicked on by Lucas to Firmino, who nodded home after reacting quicker than Craig Dawson.
Original Story: Today at 2 p.m. ET, NASA will hold a news conference announcing "new results about ocean worlds in our solar system", and more tantalizingly, "the broader search for life beyond Earth".
Cassini has no instruments that can detect life, so it will be up to future robotic visitors to seek out possible life on Enceladus, the scientists said.
"This distant moon now joins Mars and Europa as the best potential locations for life beyond Earth in our solar system", said Andrew Coates, a professor of physics at University College London.
Enceladus, a frozen moon nearly 10 times as far from the sun as Earth, at 900 million miles, was one of the least likely candidates. "So money for the moment, is still on Europa - but it could be on any of these moons".
Chelsea take another step towards the title
However, the Blues man has now gone four league games without a goal; his last one came against West Ham over a month ago. Chelsea legend Pat Nevin has found some positives in Tottenham's maintained challenge for the Premier League title.
