Sem elas nossa CIENCIA nao teria avancado.URL 01 - 02 "(...) The diversity of exoplanets is large more than 800 (2013) planets outside the Solar System have been found to date, with thousands more waiting to be confirmed (over 2000 to 2016). Detection methods in this field are steadily and quickly increasing meaning that many more exoplanets will undoubtedly be discovered in the months and years to come. As an international scientific organisation, the IAU dissociates itself entirely from the commercial practice of selling names of planets, stars or or even "real estate" on other planets or moons. These practices will not be recognised by the IAU and their alternative naming schemes cannot be adopted.

A maioria dos projetos e desenhos de Leonardo da Vinci, so foram colocados em pratica 450 anos depois. Uma das Teorias de Einstein teve que esperar por um Eclipse Total do Sol para ser comprovada.1 Ultima grande previsao de Einstein pode estar a ponto de se confirmar. Expectativa diante do possivel sinal de ondas gravitacionais e alta. Fenomeno foi previsto em 1916, mas ainda nao esta demonstrado. 2 11 de Fevereiro de 2016 e um dia historico: anunciada a deteccao pelo LIGO das Ondas Gravitacionais a partir da fusao de um par de Buracos Negros.http://eternosaprendizes.com/2016/02/11/11-de-fevereiro-de-2016-e-um-dia-historico-anunciada-a-deteccao-pelo-ligo-das-ondas-gravitacionais-a-partir-da-fusao-de-um-par-de-buracos-negros/ O Universo Eternos Aprendizeshttp://eternosaprendizes.com/3 Um seculo desde que a teoria da relatividade geral de Einstein foi anunciada, sua previsao de ondas gravitacionais foi descoberta... A century since Einstein's theory of general relativity, his prediction of gravitational waves has been verified. Nature Video brings you the key voices from the press conference that announced the discovery. - Discovering gravitational waves https://www.youtube.com/watch?v=DjLOdPOLEoc Gravitational waves: A three minute guidehttps://www.youtube.com/watch?v=hhbMpe17fzA Two Black Holes Merge into Onehttps://www.youtube.com/watch?v=I_88S8DWbcUTwo Black Holes Merge Simulation Credit: Simulating eXtreme Spacetimes Project SXS."Explanation: Just press play to watch two black holes merge. Inspired by the first direct detection of gravitational waves by LIGO, this simulation video plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage the black holes are posed in front of stars, gas, and dust. Their extreme gravity lenses the light from behind them into Einstein rings as they spiral closer and finally merge into one. The otherwise invisible gravitational waves generated as the massive objects rapidly coalesce cause the visible image to ripple and slosh both inside and outside the Einstein rings even after the black holes have merged.
