Science Cartoon based on discovery of Planet orbiting three stars

 It is too weirder. Something which is unbelievable but existing. Researchers have spotted a planet orbiting three stars with a distance twice as far as Pluto is from our own sun. As the report published online in Science magazine, the data suggest that HD131399Ab is the widest ranging exoplanet in a multistar system.

A team of astronomers have used the SPHERE instrument on ESO's Very Large Telescope to image the first planet ever found in a wide orbit inside a triple-star system. The orbit of such a planet had been expected to be unstable, probably resulting in the planet being quickly ejected from the system. But somehow this one survives. This unexpected observation suggests that such systems may actually be more common than previously thought.

Kindly find the cartoon based on above research. Feel free to share it.

Europa's Ocean May Have an Earth like Chemical Balance

 Jupiter's moon Europa always remain mysterious heavenly body for astronomy enthusiastic.  A new NASA study modeling conditions in the ocean of Europa suggests that the necessary balance of chemical energy for life could exist there, even if the Europa lacks volcanic hydrothermal activity.

The study conducted by scientists at NASA's Jet Propulsion Laboratory, Pasadena, California, compared Europa's potential for producing H₂ and O₂ with that of Earth, through processes that do not directly involve volcanism. Balance of hydrogen and oxygen is key indicator for creation of life. Study suggest the presence of favourable factors for life on Europa.

Science Cartoon on Novel Liquid wire inspired by spiders' web

Novel Liquid Wire… An inspiration from spiders’ web

Scientists from the University of Oxford, UK and the Université Pierre et Marie Curie, Paris, France worked on spider silk and published paper in Proceeding of National Academy of Science on 16^th May 2016.

They studied the properties of spiders’ webs in context to subtle balance between fiber elasticity as well as droplet surface tension and used it to create composite fibers in the laboratory which, just like the spider's capture silk, extend like a solid and compress like a liquid. These novel insights may lead to new bio-inspired technology.
