E lembre-se — esta é uma imagem de uma parte muito, muito pequena do universo. É apenas uma fração insignificante do céu noturno. | 26 imagens que lhe farão reavaliar sua existência inteira

Conventional theories suggest that this cluster of galaxies should not exist. Each fuzzy spot in this false-color image of the central regions of a newly discovered galaxy cluster is a galaxy similar in mass to our own Milky Way. The cluster is one of the most massive known, contains thousands of galaxies, and is a few million light-years across. But it is also 8 billion light-years distant and so formed when the Universe was only about half its present age.

Sinais de raios gama são gerados por várias fontes, tais como gás e poeira em espiral em buracos negros supermassivos ou explosões de estrelas. Mas outra fonte potencial de raios gama é a matéria escura. Embora ninguém tenha certeza do que é a matéria escura, uma das principais  teorias é que seja uma partícula ainda-a-ser-descoberta chamada de partícula massiva de interação fraca (WIMP). Quando duas destas WIMPs se encontram, teoricamente, elas podem se aniquilar uma a outra e gerar raios…

Spectral analysis of the composition of the newly-discovered star shows it formed approximately 13.6 billion years ago, shortly after the creation of the universe. This old star - catalogue number SMSS J031300.36-670839.3 - was found in our own Milky Way galaxy. It has a mass 60 times bigger than our Sun and is relatively close to us, some 6,000 light years from Earth.

The oldest star in the universe? Maybe, maybe not!  This week, the international media has trumpeted the discovery by Australian scientists of the oldest star in the universe, with the catchy name SMSS J031300.36-670839.3, formed in the almost pristine gas soon after the Big Bang.  This would mean the star has been slowly burning away for almost 13.7 billion years.
