Cometlike objects could be spreading life from star to star throughout the Milky Way.
Some astronomers have even speculated that life on Earth was seeded by microbes that hitched a ride on debris ejected from another life-harboring world in the solar system, perhaps on meteorites from Mars. But it seemed improbable that life could have come from interstellar space.
The analysis revealed that about a third of the meteorites shot off Earth were eventually thrown out of the solar system by Jupiter or Saturn, but that the process took millions or tens of millions of years
our entire galaxy might be considered biologically interconnected, its vast distances offset by vast spans of time and the vast number of objects that set out to cross the void.
Today on the 17th of October 1956, Mae Jemison is born. She is an American engineer, physician and NASA astronaut. She became the first African American woman to travel in space when she went into orbit aboard the Space Shuttle Endeavour on September 12, 1992. After medical school and a brief general practice, Jemison served in the Peace Corps from 1985 until 1987, when she was selected by NASA to join the astronaut corps. She resigned from NASA in 1993 to found a company researching the application of technology to daily life. She has appeared on television several times, including as an actress in an episode of Star Trek: The Next Generation.
As a teenager, I attended Space Camp @spacecampusa. This photo was taken one day in one of the lab type classrooms there. I was 16, in Space Academy Level II. I received college credit in Astronomy for participating in the program. It was all connected with the @nasa program in Huntsville. The only other photo I have from the camp is one of our entire group. I found this photo earlier in the year. I was thinking about it in the context of all the new space themed films and streaming content that is coming out lately, including @firstmanmovie. I had a t-shirt featuring Bloom County cartoon characters & they had an Opus astronaut plush toy in the room, so I had someone take my picture. I don't know what will happen in the future with our space program, but for kids and adults who are interested in science, engineering, and space exploration, Space Camp is one of those experiences that you never forget. #spacecamp#nasa#spaceexploration#summercamp#astronomy#planetaryscience#spacestation#science#explore#throwback#bloomcounty#aheadwarpzillion#opusinspace
Já se perguntaram o Motivo do Céu ser Azul?
Se vc pensou que era pq ele Refletia os Oceanos, vc está muito enganado Hahahah
UM POUCO DA EXPLICAÇÃO FÍSICA PARA ISSO:
Quando a luz passa através de um prisma, seu espectro é dividido em sete cores monocromáticas, eis que surge um arco-íris de cores. A atmosfera faz o mesmo papel do prisma, atuando onde os raios solares colidem com as moléculas de ar, água e poeira e são responsáveis pela dispersão do comprimento de onda azul da luz.
Quando percebemos a cor de um objeto, é porque ele refletiu ou dispersou, de forma difusa, o comprimento de onda associado à luz de uma determinada cor.
Devido ao seu pequeno tamanho e estrutura, as minúsculas moléculas presentes na atmosfera difundem melhor as ondas com os menores comprimentos de onda, tais como o azul e violeta.
Durante todo o dia a luz azul (menor comprimento de onda) é dispersa cerca de dez vezes mais que luz vermelha (maior comprimento de onda). Espero que tenham Gostado, Tenham uma Boa Noite, mande nosso ig para aquele seu Amigo que assim como nós é apaixonado por Astronomia.
Centaurus A is a widely known and exstensively studied galaxy located roughly 13 million light years away from our home galaxy. Shining like a brilliant beacon of light, Centaurus A is truly a sight to behold.
One of Centaurus A's notable features is it's bisecting dust lane that splits the galaxy into two halves. Due to the angle at which we see Centaurus A, it's structure and classification is highly debated. No one is quite sure on whether the galaxy is an elliptical or a lenticular.
