Astronomers Discover Object Circling Mars and Jupiter

 

asteroids have long been considered objects of fascination when it comes to space exploration cirrus and vesta are two of the earliest and most massive asteroids ever discovered in our solar system so much so that they were once counted among the planets even before pluto had been discovered nasa launched dawn its spacecraft which successfully completed its mission to explore vesta and ceres and uncover the secrets of these fascinating objects welcome to fact nominal and in today's article we will be taking a look at some of the most surprising discoveries and stunning images from series investor captured by nasa's dawn mission probe

 ever wondered what those rocky objects circling the sun that are too small to be considered planets are well that's an asteroid for you some would even call them planetoids or minor planets space is full of these objects ranging

 from all different shapes and sizes

 they can be found all throughout the solar system but one of the main regions you would find them is the region between mars and jupiter a debris strewn main asteroid belt in 1801 while making a star map giuseppe piazzi stumbled upon a small object about 1 000 kilometers in diameter between the orbit of mars and jupiter the first ever asteroid to be discovered ceres from then on more and more asteroids seemed to be popping up on astronomers radar so to speak but asteroids are by no means innocent little space rocks they can actually be quite dangerous they've been known to zoom straight into planets and cause major damage on the surface like causing massive craters for example because of this scientists have recognized the need to study these asteroids and find out all they could about them all eyes were turned towards these newly discovered space rocks and the main asteroid belt specifically ceres and its neighbor vesta the second most massive body discovered in the asteroid belt for many years after their discovery both were considered to be asteroids but ceres for example being so much bigger than its other rocky neighbors was given an upgrade in 2006 after much debate over its classification they decided that it was simply too big in comparison to the other rocky material floating around in the main asteroid belt to be simply called an asteroid and they decided that ceres was now a dwarf planet vesta on the other hand wasn't quite large enough to be deemed a dwarf planet but scientists prefer to think of it as a protoplanet because of its dense layered body that seemingly orbits the sun in a manner similar to mars venus and earth there are so many questions that have had scientists and astronomers scratching their heads about the formation of our solar system and the early days in a quest to find answers it is important to take a trip back in time to truly understand how everything came to be as a part of nasa's discovery program dawn a mission was launched to address the role size and water in determining the evolution of the planets and as you have it ceres and vesta were just the right bodies to address these questions being minor planets whose growth was interrupted by the formation of jupiter dawn was nasa's first truly interplanetary spaceship that took a journey through space and time almost like going back and opening up a space-time capsule the spacecraft was boosted by an innovative ion propulsion system and took nearly 4 days to accelerate from 0 to 60 miles per hour at maximum throttle the orbiter was launched at the cape canaveral air force station in florida with its target set for the two massive bodies after traveling a whopping 1.7 billion miles the dawn spacecraft made its arrival at the proto-planet vesta on july 16 2011 where it spent a little over a year in orbit around the second largest object in the asteroid belt dawn made some fascinating discoveries on vesta while in orbit first it found two colossal impact

 basins in the vesta's southern hemisphere the ria sylvia basin is 310 miles wide and the much older 250 mile wide venenaia crater data from dawn showed that the reyes

 silvia's peak rises 12 to 16 miles

 and is more than 100 miles wide putting it in direct competition with olympus mons on mars as the largest mountain in the solar system the spacecraft was also able to map out

 vesta's geology composition cratering record and more images from the mission show its heavily cratered surface with a rough topography the pitted terrains and gullies found in several young craters were taken as evidence of

 transient water flow a key finding was

 that dawn confirmed that vesta is the parent of the head power diets eucrates and diogenetics meteorites found on earth and mars which is connected to vesta's large south polar basin the proto-planet is small enough to have been deeply scarred by the ray of silvia impact and launched all the heads but also large enough to have differentiated into an iron core igneous crust and silicate mantle hydrated and carbon-rich material was also found on vesta's surface the research from dawn also suggests that it could be hiding ice beneath its surface it would explain much of why the surface of esta is the way it is and ice could have played a dominant role in shaping vesta named after the roman goddess of corn and harvests ceres was a big target for dawn with a radius of 296 miles or 476 kilometers it only amounts to 1 13th the radius of the earth to put that into perspective if earth were the size of a nickel then ceres would be a mere poppy seed on september 5th 2012 after leaving vesta don began its track towards the dwarf planet series another 3.1 billion miles away while vesta is more of a rocky world ceres is surprisingly icy it was here that dawn discovered that the inner solar system's only dwarf planet

 was actually an ocean world where water

 and ammonia reacted with silicate rocks

 it appears to have been formed farther from the sun and migrated into the inner solar system after measuring series surface composition don found ammonia which requires colder temperatures like that of the outer solar system to condense finding that ceres is also an ocean world is probably one of the biggest findings from the dawn mission water is essential to sustain life and any ocean worlds that have been discovered immediately becomes the main focus for further exploration because they could support conditions that are suitable for life like titan and enceladus for example this is important because studying an evolved dwarf planet like ceres could teach us a lot about the environmental conditions at other ocean worlds additionally an abundance of organic molecules which are the building blocks of life were found in the emittet crater region though scientists still aren't exactly sure of the origins of series organic molecules they can be associated with life and non-biological processes as well series features an array of bright spots called faculae that shine on top of the otherwise dark landscape of the dwarf planet in fact the brightest area in the aquitar crater on ceres is the largest deposit of carbonate materials ever seen beyond earth these minerals are associated with oceanic and lake environments making ceres an even more exciting ocean world to explore it also has volcanic activity the dwarf planet is home to an enormous volcano ahunamans which stands three miles or five kilometers high on its steepest side which the dawn team believes was initially formed as a cryovolcano while most of ceres is seemingly

 smooth and rather bland this

 just goes to show it is geologically

 active or at least was some time ago

 after more than 11 years of exploration in october 2018 it was time to conclude dawn's mission despite significant challenges dawn explored about 45 of the entire mass contained in the main asteroid belt most notable of course was the 3.7 years it spent in orbit around ceres and 1.1 years around vesta giving us insight into these space wonders no other spacecraft has been able to explore these two massive objects in the main belt area and provide a rich harvest of scientific data along with some breathtaking images though dom answered many questions and filled in several knowledge gaps about series investa it has given us more reason to further explore the two minor planets the lessons we learned from dawn will no doubt help with future missions although the mission was cut short in 2018 by the lack of fuel nasa announced that it will continue to orbit series for another 50 years the spacecraft is a true testament to human creativity and shall serve as a lasting reminder that passion for bold adventure and the hunger to know more about what lies in the cosmos can take us way beyond what we could ever imagine that's all for today folks what are
