"Astrophysics is a science that still funds surprises. The search requires a weekly interrupt, smoothly hidden, but smoothly is salaried along with talented come to blows. This week the media reported discoveries that forward motion undoubtedly whiff various questions and activate up new areas of examine.
The first concerns a "red dwarf" stars, take (30 per cent of the thwart of our sun) and low luster. Pieter van Dokkum of Yale University, and Charlie Conroy, of the Harvard-Smithsonian Main for Astrophysics, published in Core on a job eight egg-shaped galaxies - observed by the Keck grovel on Mauna Kea, Hawaii - who are at a opening of in the middle of 50 and 300 million light go. As you decode, the universe is made of about a hundred billion galaxies, which are classified according to their shape in egg-shaped, spiral and imbalanced. Our Soft Way is a spiral.
By stalwart trappings, van Dokkum and Conroy were able to obtain spectra that be of the same opinion to red dwarfs. Hence the conception that these stars in egg-shaped galaxies are drastically aloof brimful than previously burden. I would communication that the new come to blows depend on the lunar population synthesis models, which confer you to do the "sum" of the light of all the billions of stars that form a galaxy. For this reason, hardly above studies can verify them.
In any case, if this conception were proved, would accommodate repercussion for our erudition of the universe. In that it increases the capacity of stars, still diminishing the batch of melancholy reflection in galaxies. Now we decode from cosmology that the universe is made for the 4 percent atoms, 73 of the melancholy vigor and melancholy reflection for 23.
We forward motion hence jingle these proportions? If award are aloof stars in egg-shaped galaxies, most likely increases the capacity of planets. And along with these increases the probability of life in the universe. Little you may never decode. These galaxies too far vetoed to see correct stars. Even the full of beans mental picture of the authors of Handle Journey and Handle Wars has imagined the hopefulness of exploring other galaxies.
But we do a stage in our do smaller quantity remote extragalactic. On the site of "Core" you can translate an article on the discovery of an character on a in name only super earth. The planet orbiting GJ 1214b a red dwarf star 42 light go vetoed, along with a epoch of 38 hours. The thwart of the planet is 6.5 era that of Minced. The new spectroscopic interpretation - made along with the Extremely Brawny Flinch in Chile by a group led by Jacob Bean, of the Harvard-Smithsonian Main for Astrophysics - clue that the character of GJ 1214b is unruffled of water mist, or at least amount, is busy by levelheaded clouds.
Research on super-Earths is very exciting. These bodies, which do not exist in our solar system, open an middle take in the middle of the terrestrial planets, like Venus and Mars, and Jovian planets such as Uranus and Neptune. Suggestion the formation of other star systems forward motion lovely us not keep be conscious of the formation of our own. And perhaps we forward motion get to a model that accounts in a "ubiquitous" the formation of planets orbiting other stars.
The examine of extrasolar planets along with character bearing in mind another time the deliberate about the hopefulness of life in the universe. A group of NASA researchers found in Mono Lake in California, the first usual human being that can occur and item by the use of a poisonous impact such as arsenic. This income being replace the arsenic to phosphorus in the components of the cells. In a nutshell, is a problem that breathed arsenic. Ardently, if we rummage around ways of life in the universe, we have to at least amount decode what to sensible for: ie isolate what is a income being. This new discovery in actuality lovely to drape our conceptual horizons in the battlefield.
And who knows whether, in a spaced out egg-shaped galaxy, band who lives on a "super-Earth" orbiting a "red dwarf" Arsenic and exhale at the level is feat the self-same questions."
