Otkriven „groteskni“ brat blizanac Sunčevog sistema - National Geographic Srbija Sistem GJ676A je mnogo veći od našeg, ali mu veoma nalikuje, kažu astronomi… Astronomi su uočili našeg, kako kažu „grotesknog“ blizanca: planetarni sistem organizovan vrlo slično kao Sunčev sistem, otkriva se u novoj studiji. Nazvan GJ676A, sistem je koji ma dve kamenite planete koje orbitiraju u blizini zvezde i dva gasovita giganta koja su udaljena. To znači da je sistem uređen vrlo slično kao naš – osim što je u GJ676A sve mnogo veće. Na primer, najmanja kamenita planeta u ovom sistemu ima masu najmanje četiri puta veću od Zemlje, dok je najveći član sistema pet puta veći od Jupitera. I drugi sistemi koji se sastoje od više planeta su otkriveni do sada, poput onog nazvanog HD10180, koji se smatra najbogatijim egzoplanetarnim otkrićem jer ima sedam do devet planeta koje orbitiraju oko zvezde. Dugačke orbite gasovitih giganata i kratke orbite ekstremno toplih super Zemlji su ono što je navelo astronome da nazovu GJ676A bratom blizancem našeg Solarnog sistema.
NASA Earth Observatory : Home Harvard Science Outreach Program: Resources Birth of the Moon | SpaceRip Posted by admin on Saturday, February 11, 2012 · The latest episode of Cosmic Journeys, enjoy in full HD 1080p. Scientists have been reconstructing the history of the moon by scouring its surface, mapping its mountains and craters, and probing its interior. What are they learning about our own planet’s beginnings? Decades ago, we sent astronauts to the moon as a symbol of confidence in the face of the great cold war struggle. Landing on the moon was a giant leap for mankind. When the astronauts of Apollo stepped out of their landing craft, they entered a world draped in fine sticky dust, strewn with rocks, and pocked with craters. Back in earth-bound labs, scientists went to work probing the rocks for clues to one of the most vexing questions in all of science. The nature of the moon began to come into focus four centuries ago. What was the nature of the heavens, and how did the world of men fit within it?
NASA Robotics - Robotics Alliance Project Interactive 3D model of Solar System Planets and Night Sky Exoplanets An interactive version of XKCD 1071: Exoplanets using data from Planetary Habilitability Laboratory (via @ProfAbelMendez) and adapted code from the d3.js Bubble Chart example (by @mbostock). Planets are drawn to scale using radius data. The dataset also includes attributes such as atmosphere type, which is included in the information area on the left. The dataset is large (about 1.1mb), so it may take a few seconds to load. All blue and light brown planets are smaller than Jupiter. Brown represents the planets larger than Jupiter, while red represents the largest of them all. Code can be found on github, and I can be found at @laneharrison. Special thanks to Drew Skau (@SeeingStructure) for help with the design details.
