Space Archaeopteryx

The telescope «Herschel» discovered in the constellation Cetus, at a distance of 11 billion light-years away, a giant galaxy. It was formed as a result of the collision of two large galaxies more (X01N and X01S), consisting of about 400 billion stars each. The galaxy, which was named NHMM01, new stars began to appear — to 2000 units per year! For comparison, in our own galaxy — the Milky Way — are born every year is only two or three stars. Collision of galaxies in the cosmos is not uncommon. The singularity of the findings in that. that it is a transitional link between overactive ancient «stellar megacities» and modern elliptical galaxies — and allows you to answer many questions about the early history of the universe. «The opening of this galaxy is just as important to astronomy as the discovery of Archaeopteryx — for paleontology. — Said the study’s lead author Hai Fu of the University of California. However, «short-lived» — is by the standards of astronomy; According to calculations of scientists, galaxy NHMM01 «quieted down» a few tens of millions of years of such intense star formation. We still have plenty of time to watch the happening, because seen «Herschel» events belong to the distant past. The clash occurred after three billion years after the Big Bang — that is 13.8 billion years ago.

«I am your brother — Gemini, the Sun!»

Brazilian scientists from the Federal University of Rio Grande do Norte using the Subaru Telescope and CoRoT discovered in the Milky Way in the constellation Monoceros, twin of our sun. However, it is already pretty in years — older brother more than 2 billion years old. The rest of the open star is very much like the sun; has about the same mass and composition similar (but contains significantly less lithium), the rotation period is 29 ± 5 days (the Sun’s outer layers wrapped around 25 days). The star was named CoRoTSol 1. Astronomers are extremely interested in this discovery — it lets you see what happens to our star (and, consequently, to the planet) in the future. So far, the forecast disappointing: apparently two billion years the solar radiation will increase, and the Earth’s surface warms up so that it will no longer liquid water. If Brazilians are not mistaken, with the development of astronautics would have to hurry!
