Ocean On Jupiter’s Moon May Harbour Life: Nasa

The Europa ocean on Jupiter's icy moon may have the Earth-like balance of chemical energy necessary for life, even if the moon lacks volcanic hydrothermal activity, a new Nasa study suggests.


Europa is strongly believed to hide a deep ocean of salty liquid water beneath its icy shell. Whether the Jovian moon has the raw materials and chemical energy in the right proportions to support biology is a topic of intense scientific interest.

The answer may hinge on whether Europa has environments where chemicals are matched in the right proportions to power biological processes. Life on Earth exploits such niches.
In a new study, scientists at Nasa's Jet Propulsion Laboratory (JPL) in California compared Europa's potential for producing hydrogen and oxygen with that of Earth, through processes that do not directly involve volcanism.

The balance of these two elements is a key indicator of the energy available for life. The study found that the amounts would be comparable in scale; on both worlds, oxygen production is about 10 times higher than hydrogen production.

The work draws attention to the ways that Europa's rocky interior may be much more complex and possibly Earth-like than people typically think, according to Steve Vance, a planetary scientist at JPL and lead author of the study.

"We're studying an alien ocean using methods developed to understand the movement of energy and nutrients in Earth's own systems. The cycling of oxygen and hydrogen in Europa's ocean will be a major driver for Europa's ocean chemistry and any life there, just as it is on Earth," said Vance.

  • About Us

Times Newspaper in Education (Times NIE) is a novel program that helps students ‘Stay Ahead’ and aims at making ‘Learning Fun’. It introduces concepts that help individual growth and development beyond school curriculum.

A brainchild of The Times of India, the world’s leading English newspapers, Times NIE nurtures progress and innovation. Adapted from the international concept, Times Newspaper in Education program (Times NIE) was initiated in India in 1985.

Today we have over 3000 schools and over 9 lac students subscribing to the programme, spanning 16 cities viz. Delhi, Mumbai, Pune, Bangalore, Kolkata, Chennai, Hyderabad, Ahmedabad, Kochi, Lucknow, Coimbatore, Chandigarh, Dehradun, Vijayawada, Visakhapatnam, and Jaipur.

The Times of India Student edition, a customized student newspaper exclusively for the students, packs a powerful punch in terms of content that leads to a smarter and superior learning experience. The information is crafted such that it finds use in classroom discussions, thus making it relevant and current. It truly gives education a new dimension by fostering the simple habit of reading which in turn paves the way for a confident, informed and aware individual. A newspaper that inspires young minds and equips them to face challenges of today’s world, making way for global citizens.

Empowering students with new cutting-edge knowledge through various educative and informative activities is a commitment and tradition of Times NIE. The programme serves as a catalyst of education and interaction, as well as a window into the minds of the quintessential Indian youth. On a significant scale Times NIE comprises diverse interesting activities and events that boost the child’s passion for learning, while revealing hidden talent.

While you are aware that The Times of India is among the leading English Newspapers across the world, it has consummated its position as an everlasting winner. With several international awards and recognitions to its credit, The Times of India and Times NIE have validated an enduring tradition of setting the highest benchmarks in every respect. We have been awarded with the two most prestigious awards, Times NIE - World’s No.1 NIE program and The Times of India, Student Edition - World’s No.1 Newspaper for the youth in 2006 by the celebrated World Association of Newspapers (WAN). In 2008 we were honoured by the International Newspaper Marketing Association (INMA), yet another international recognition for ‘Youth Audience Development’. In 2013 we were again honoured by the celebrated World Association of Newspapers (WAN) as the ‘Times NIE - World’s Best Youth Engagement Program’.

Times NIE has grown remarkably over the last three and a half decades, touching millions of children across more than 16 Indian cities. Our absolute commitment towards the fledgling generation remains undiluted and our greatest strength lies in the school partnership and commitment.
