Telescópio do SETI teria detectado sinal extraterrestre

ratan-600

Astrônomos usando o telescópio de rádio RATAN-600 da Rússia registraram “um sinal forte na direção de HD164595”, de acordo com Paul Gilster, da Centauri Dreams, que obteve acesso a um documento que está circulando nos bastidores.

A pesquisa não foi publicada ainda, mas de acordo com a Gilster, o sinal será discutido durante uma reunião do SETI no 67º Congresso Internacional de Astronáutica (IAC) , em Guadalajara, México, em setembro.

O sinal em questão parece ser uma explosão de rádio com uma frequência de 11 GHz foi detectado pelo observatório em 15 de Maio, 2015, vindo de HD164595, que está localizada a 95 anos-luz de distância e é conhecida por possuir um exoplaneta.

Este exoplaneta teria cerca de 4% da massa de Júpiter, com uma órbita de 40 dias. Embora o planeta seja inabitável para a vida como a conhecemos (por estar muito perto da sua estrela), podem haver outros planetas desconhecidos no sistema.

No entanto, os pesquisadores adiaram seria extremamente improvável que tenha sido gerado por alienígenas e sim por explicações mais simples, talvez pela existência de alguma “sonda militar” naquela área.

Mas antes de descartar a ideia totalmente, o SETI ajustou suas 42 antenas de rádio na Califórnia, do Allen Telescope Array, para a estrela na esperança de replicar a observação RATAN-600.

Agora somente temos que aguardar pelos próximos episódios desta história.

Young Suns of NGC 7129


Young suns still lie within dusty NGC 7129, some 3,000 light-years away toward the royal constellation Cepheus. While these stars are at a relatively tender age, only a few million years old, it is likely that our own Sun formed in a similar stellar nursery some five billion years ago. Most noticeable in the sharp image are the lovely bluish dust clouds that reflect the youthful starlight. But the compact, deep red crescent shapes are also markers of energetic, young stellar objects. Known as Herbig-Haro objects, their shape and color is characteristic of glowing hydrogen gas shocked by jets streaming away from newborn stars. Paler, extended filaments of reddish emission mingling with the bluish clouds are caused by dust grains effectively converting the invisible ultraviolet starlight to visible red light through photoluminesence. Ultimately the natal gas and dust in the region will be dispersed, the stars drifting apart as the loose cluster orbits the center of the Galaxy. The processing of this remarkable composite image has revealed the faint red strands of emission at the upper right. They are recently recognized as a likely supernova remnant and are currently being analyzed by Bo Reipurth (Univ. Hawaii) who obtained the image data at the Subaru telescope. At the estimated distance of NGC 7129, this telescopic view spans over 40 light-years.

In the middle of the 1930s Mayor LaGuardia was faced with a very difficult problem. A high-ranking German diplomat was due for a state visit in New York. Shocked and angered by the recent anti-Jewish laws of the Nazis, a great number of New Yorkers threatened to do bodily harm to the diplomat. The mayor himself abhorred the Nazis, but it was his sworn duty to prevent violence.

He solved the problem by surrounding the Nazi representative with a bodyguard of police. They all had one thing in common – they were Jewish. The joke embarrassed the Nazis and caused enormous laughter. But it also resolved a potentially dangerous situation.

An Age-defying Star


An age-defying star designated as IRAS 19312+1950 (arrow) exhibits features characteristic of a very young star and a very old star. The object stands out as extremely bright inside a large, chemically rich cloud of material, as shown in this image from NASA’s Spitzer Space Telescope.
