For the first time, astronomers were able to catch the formation of a planetary system. The paper, published in Nature, suggests that the observed objects are infant planets, currently being pieced together by extremely hot gas and dust. Using images of the system taken between 2009 to 2015, the team was able to identify two protoplanets – small objects that go on to form planets – alongside a potential third, moving around the star LkCa 15 in an elliptical orbit, as it is expected of planets. Detecting planets forming is a complex task. Newborn stellar systems are usually enshrouded in a cloud of dust that muddies our view, making normal detection methods unsuitable. The team therefore had to develop a different approach to study the system. Young stars produce large disks of material from which planets form. As growing planets move through this protoplanetary disk, they create gaps in the swirling debris, which astronomers can detect using infrared light. Several protoplanet candidates were discovered this way. Planets undergoing formation increase in size thanks to the smaller disks of material, similar to the ones around stars, that form around them. As material from this circumplanetary disk falls on the planet, it gets hotter which makes the planet appear redder than it actually is, and visible to us in infrared. The planet's magnetic field might also affect the disk of dust and gas surrounding it. A strong magnetic field forces the material in the disk to follow specific orbits. The energy generated within the disk heats up the magnetosphere of the planet to a temperature higher than the surface of the Sun, and the heated material produces a specific emission called hydrogen-alpha. The team combined observations in infrared from the Large Binocular Telescope , with hydrogen-alpha analysis by the Magellan Telescope. The gap around LkCa 15 was first observed in 2011, which indicated the potential for the star to host at least one exoplanet. For this latest study, the team was able to identify hot gas (9,700°C [17,500 °F]) falling onto the closer planet LkCa 15b. Looking at the data from the system, scientists realized there were other emissions in the gap: One signal was recognized as a second planet after being observed several times. A third emission is thought to be another planet but is yet to be confirmed. "Observing emission lines such as H-alpha is a powerful tool for tracing accretion onto protoplanets directly. I think this technique will be very useful for finding protoplanets around other stars as well." Steph Sallum, lead author of the study, told IFL Science This discovery and the success of this technique provides new opportunities to study how planetary systems form and how young planets interact with the disk of material around the star. http://www.iflscience.com/space/witnessing-birth-planets-0 Below is an artistic impression in a transmission disk like LkCa 15. 5 Likes 3 Shares

Brainaic: I am here sir to answer your call. . . It is breathe taking and it is wonderful... What we can unravel in this universe if only we can drop our assumptions and take a peek into the void to what it can teach us. This development have confirmed my position always when i discuss with people. "Always agree you don't know when you lack knowledge and then strive to know through consistent study and observation.." Now man is getting first hand the picture of how planets formed, now we have through consistent study and observation unravelled that knowledge.. Oh what this universe can teach us if only we can open up to it to teach us.. If only we could drop our assumptions and unfounded beliefs and follow the evidence where ever it leads us with humility and openness of heart, hunger to know and curiosity . . . What a much nobler cause that will be... 5 Likes 4 Shares |

johnydon22: But the witnessed birth of the new star will be so miniature because of the time frame scientists have been observed it( pictures taken btw 2009 to 2015). I tot the birth of new stars do take some millions if not billions of years |

menesheh: The Star, LkCa 15 is 2 million years old. What the scientists witnessed is the formation of a new planet, LkCa 15 from the star. |

menesheh: Yes that's why its called Protoplanet but i don't think it takes billions of years. . They are still in formation and their parent star is still a very young star perhaps some millions of years old. This is the action of Gravity on Matter which defines the very cause and effect of almost every observable action in our observable universe.. The planets will accumulate more materials within period of time and gets bigger and denser ... These are more like Infants. i.e: remember we are looking back in time considering the amount of time light from these distant points takes to reach us.. 2 Likes 2 Shares |

herald9: Edwin Hubble provided Proof for the Big bang propounded by Rev Fr Georges Lamitre.. Hubble confirmed the universe was actually expanding. space and time itself is expanding like a fabric and so all the matters on it goes along with it. . . The point or singularity where this expansion began is what science call BIG BANG.. 2 Likes 2 Shares |

herald9: As a matter of fact the theory always accounted for such. . . According to the theory (Not Johnydon22) There was something like a rapid inflation of the singularity before the expansion began. And afterwards the newly born Universe cooled and sub-atomic particles and then normal atoms formed (From whence you get matter **The dust and gas you pointed out) which in turn through gravity formed into stars and galaxies ... Man have no idea what Dark energy or Dark matters are yet, that knowledge might redefine what we think we know anytime soon.. 1 Like |

Brainaic: It wasn't a joke actually any believer of a religion would come here to argue that a kind of deity spoke the earth into existence. Some would even assert the earth was created before it's parent star (sun) which is a very absurd notion. Man is ascertaining through study the actual events in planetary formations which is exactly the same phase EARTH passed through in it's formation but people think the earth popped out magically when a deity spoke to himself and then the sun was created 4 days later.. Not only is it ridiculous, it is embarrasing 5 Likes 4 Shares |

what's actually shocking about all of this is, at this current moment, those planets are at least several thousand years old.  and any intelligent life on it might be arguing that they were created by God.  i just keep wondering if any alien civilizations witnessed the formation of our planets. they could just travel over and show us.  1 Like 1 Share |

menesheh: hahn: johnydon22: Brainaic: lol. calm your tittties fam.  I'd love to think that on the front line of the battle of advantages with eras preceding ours, the most lethal weapon in the armoury of the 21st century man, is his open mindedness. But sadly, very few are really making commendable use of such a powerful tool. I simply mentioned God and you're all going bonkers about me 'attributing something I don't understand to God.'Actually, I do believe in God (or whatever name you choose to call the superior and unfathomably advanced intelligence responsible for what we know today as nature) and at the same time, I'm just as much an evolutionary theorist as yourselves. You don't simply rule out the existence of things you do not know just because they go over your head. But would you open minded enough to see things from my perspective?? See it this way: God built the observable (and non observable) universe -- literally. You don't expect Him to have carried those rocks that constituted the big bang theory manually like a bricklayer from point A to point B. He, from the omnipresent standpoint, did the background work and set these things in motion which we uncover today and study as the origin of the universe. The other universes are most likely earlier workbenches. Recently I was quite fortunate to come across this http://www.bbc.com/earth/bespoke/story/20150123-earths-25-biggest-turning-points/index.html These things weren't merely happening on their own; it was someone working. Why not look at it this way?? |
