                A blue Supergiant star(artist's view).                                                                                                       Astronomers study the nature of Blue Supergiant Stars for decades. Blue Supergiants are difficult to study because they have a short lifetime as they die young. Stars temperature are determine by their colour - Blue Supergiants are hottest while Red stars are the coolest. Blue Supergiants have a surface temperature between 20,000℃ to 50,000℃.                                                                                           Blue Supergiants are the final burning phase before the death of a super massive star in Supernovae. Research are limited on these giants due to unavailable technology and equipments because telescopes can't see the interior of stars.             The illustration in this video shows the waves generated in the interior of a star.                                                            

                      A artist's impression on Dragonfly probe.                                                                                                                                                                           A week ago, American space agency NASA announced it's next destination in solar system. NASA planning a mission to Saturn's moon, Titan in search of Alien life, they named this project as 'Dragonfly'. Dragonfly was selected as part of agency's new frontiers program, which includes the New Horizons mission to Pluto and the kuiper Belt, Juno to Jupiter and OSIRIS REX to the asteroid Bennu.                                    Dragonfly is the first multi rotor vehicle for science on another planet, it contains eight rotors. It is dual quardcopter lander ( a Mars rover-size, drone like vehicle) that will explore the prebiotic Organic Chemistry of Titan, the biggest of Saturn's 62 moons.
