Por causa de seu tamanho gigantesco, tem um papel muito importante na formação e evolução do nosso sistema planetário. Até mesmo com implicações no desenvolvimento e longevidade da vida na Terra. Com sua massa de aproximadamente 320 vezes a massa da Terra, ele atrai, desvia e até mesmo engole uma grande quantidade de cometas e asteroides errantes que, se não fosse assim, viria para as partes mais internas do sistema cruzando perigosamente a órbita da Terra. Numa dessas, um cometa a caminho do Sol resolve dar uma passadinha pela Terra e já era. Pergunte aos dinossauros. Além de ser o maior dos planetas no nosso sistema, Júpiter é também o mais velho deles.
Uma boa ideia desse tempo foi apresentada por uma equipe internacional do Laboratório Nacional Lawrence Livermore, sediado na Califórnia, EUA. Essa conclusão veio da análise de meteoritos ferrosos que caíram na Terra. Uau, era um cometa? This awesome periodic table shows the origins of every atom in your body - ScienceAlert.

International Union of Pure and Applied Chemistry Periodic Table of Elements. The latest release of the Periodic Table (dated 1 Dec 2018) includes the most recent updates released in June 2018 by the IUPAC Commission on Isotopic Abundances and Atomic Weights (CIAAW) (see related News,released 5 June 2018), and specifically for argon, the assignment of an interval for the new standard atomic weight which reflects the common occurrence of variations in the atomic weights of the element in normal terrestrial materials.
An interval in square brackets provides the lower and upper bounds of the standard atomic weight for that element. For users needing an atomic-weight value for an unspecified sample with disregard to the uncertainty, the conventional values are provided. No values are listed for elements which lack isotopes with a characteristic isotopic abundance in natural terrestrial samples.

Foi a primeira vez que uma jovem brasileira teve a oportunidade de pronunciar discurso como representante da juventude global numa plenária final de COP.
Em seu discurso, Raquel Rosenberg, coordenadora do Engajamundo, deixou claro que a juventude continuará pressionando os governos na luta contra as mudanças do clima Depois de duas semanas de negociação, a Conferência do Clima de Paris (COP 21) aprovou o Acordo de Paris, o primeiro tratado internacional sobre clima de caráter universal, no qual todos os seus signatários possuirão compromissos de redução de emissões a partir de 2020, num esforço concertado para limitar o aquecimento global bem abaixo dos 2 graus Celsius neste século, preferencialmente em 1,5 grau Celsius.
Na plenária final da COP 21, como de costume, organizações observadoras tiveram uma breve oportunidade para se pronunciar oficialmente. Raquel Rosenberg - Engajamundo/YOUNGO Bonn 2015. More drought, floods predicted for the Amazon - Conservation news. Sao Paulo, Brazil’s most populous city, is currently suffering from a severe drought.
Meanwhile, over the past year, record floods have hit other parts of Brazil. Though Sao Paulo is hundreds of miles from the rainforest, a study released earlier this year by one of Brazil’s top climate scientists found that deforestation in the Amazon is at least partially to blame for the drought gripping the city and much of the southeastern part of the country. These types of “hydrological extremes” are becoming more frequent in Amazonia. A drought in 2005 was considered a once-in-100-years event until it happened again — this time worse — in 2010. In addition to deforestation, government officials also blame global warming for the extreme weather. Home - Edward Frenkel. Why do people hate mathematics? I am or AI am?
