Within a million years after the Sun's creation, Earth was formed. In a protoplanetary disc, a second [generation](https://www.mindstick.com/blog/300788/why-is-heart-attack-increasing-in-the-younger-generation) of planets can emerge. ## WHY IN [NEWS](https://www.mindstick.com/developersection/news) Planets develop rather quickly after stars have created. The Sun, for example, originated 4.6 billion [years ago](https://yourviews.mindstick.com/view/81912/humans-lived-in-america-more-than-30000-years-ago), whereas the Earth formed around 4.5 billion years ago. However, experts now believe that this is not the only possibility. They claim that planets can develop long after a star has created, even if it is reaching its end. The idea of dying stars contributing to the creation of planets is a novel one. If validated, this [discovery](https://www.mindstick.com/interview/34385/understanding-the-discovery-phase-in-software-development-part-1) might revolutionise [our understanding](https://answers.mindstick.com/qa/115266/how-did-stephen-hawking-contribute-to-our-understanding-of-the-universe-despite-his-illness) of the universe's functioning and planetary evolution. After the Sun formed initially, the Earth and other planets in [our solar system](https://answers.mindstick.com/qa/35770/which-is-the-second-largest-moon-in-our-solar-system) formed quickly. Matter around the Sun clumped into a protoplanetary disc within a million years of its origin. **ALSO READ :** [**The three-month alignment process for the James Webb Space Telescope has begun**](https://www.mindstick.com/news/1366/the-three-month-alignment-process-for-the-james-webb-space-telescope-has-begun) Planets were created on this disc, which is a massive pancake consisting of dust and gas with the Sun in the centre. However, young stars, such as the Sun, aren't the only ones that have a disc of raw material spinning around them. These discs can also be seen on certain ancient, dying stars. For example, one of the binary stars — two stars orbiting each other — is dying. According to a research published in the journal Astronomy & Astrophysics titled 'A [population](https://answers.mindstick.com/qa/33541/list-top-10-tiger-reserves-in-india-with-maximum-tiger-population) of [transition](https://answers.mindstick.com/qa/94090/a-material-is-dimensionally-stable-at-room-temperature-if-its-glass-transition-temperature-tg-is) discs surrounding evolved stars: Fingerprints of planets,' the gravitational attraction of the second star may cause the ejected material from the dying star to create a new revolving disc. **ALSO READ :** [**Spectrum bids will be held this year to help with the deployment of 5G networks**](https://www.mindstick.com/news/1368/spectrum-bids-will-be-held-this-year-to-help-with-the-deployment-of-5g-networks) But we already knew that. The notion of a second generation of planets forming in the disc is novel. According to the study, planets develop in one out of every ten binary stars. Jacques Kluska, the study's first author and a KU Leuven astronomer, revealed that they discovered a large cavity in the disc in 10% of the evolved binary stars with discs they studied. Kluska went on to say that this meant something was floating nearby and had gathered all of the stuff in the cavity's proximity. This object might very well be a planet, but scientists aren't positive just yet. The riddle is likely to be solved with more investigation. --- Original Source: https://www.mindstick.com/news/1370/is-it-possible-for-dying-stars-to-give-birth-to-new-planets Copyright © MindStick Software Pvt.
