Using NASA's Kepler Space Telescope and its extended K2 mission, astronomers have discovered a newborn fully-formed exoplanet -- planets that orbit stars beyond our Sun -- ever detected around a young star.

The newfound planet named K2-33b is a bit larger than Neptune and whips tightly around its star every five days.

It is only five to 10 million years old, making it one of a very few newborn planets found to date.

"Our Earth is roughly 4.5 billion years old. By comparison, the planet K2-33b is very young. You might think of it as an infant," said led researcher Trevor David from California Institute of Technology (Caltech).

Astronomers have discovered and confirmed roughly 3,000 exoplanets so far. However, nearly all of them are hosted by middle-aged stars, with ages of a billion years or more.

"The newborn planet will help us better understand how planets form, which is important for understanding the processes that led to the formation of the Earth," added co-author Erik Petigura from Caltech.

The first signals of the planet's existence were measured by K2. The telescope's camera detected a periodic dimming of the light emitted by the planet's host star, a sign that an orbiting planet could be regularly passing in front of the star and blocking the light.

"Initially, this material may obscure any forming planets, but after a few million years, the dust starts to dissipate," said co-author Anne Marie Cody, a NASA postdoctoral programme fellow.

A surprising feature in the discovery of K2-33b is how close the newborn planet lies to its star. The planet is nearly 10 times closer to its star than Mercury is to our sun, making it hot.

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’.

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.
