#Rare molecule found in space hints at life s origins The discovery of an unusual carbon-based molecule near the galactic center of the Milky way suggests that the complex molecules needed for life may have their origins in interstellar space.
Organic molecules usually found in these star-forming regions consist of a single ackboneof carbon atoms arranged in a straight chain.
The carbon structure of this molecule known as isopropyl cyanide is branched making it the first interstellar detection of such a molecule says Rob Garrod a senior research associate at the Center for Radiophysics and Space Research at Cornell University.
This detection opens a new frontier in the complexity of molecules that can be formed in interstellar space
and that might ultimately find their way to the surfaces of planets says Garrod. The branched carbon structure of isopropyl cyanide is a common feature in molecules that are needed for life such as amino acids
The discovery reported in the journal Science lends weight to the idea that biologically crucial molecules like amino acids that are commonly found in meteorites are produced early in the process of star formation even before planets such as Earth are formed.
Garrod along with lead author Arnaud Belloche and Karl Menten both of the Max Planck Institute for Radio astronomy and Holger MÃ ller of the University of Cologne sought to examine the chemical makeup of Sagittarius
B2 a region close to the Milky way s galactic center and an area rich in complex interstellar organic molecules.
Using the Atacama Large Millimeter/submillimeter Array (known as the ALMA Observatory) the group conducted a full spectral survey looking for fingerprints of new interstellar molecules with sensitivity and resolution 10 times greater
The purpose of the ALMA Observatory is to search for cosmic origins through an array of 66 sensitive radio antennas from the high elevation and dry air of northern Chile s Atacama desert.
The array of radio telescopes works together to form a gigantic yepeering into the cosmos. nderstanding the production of organic material at the early stages of star formation is critical to piecing together the gradual progression from simple molecules
The two molecules isopropyl cyanide and normal-propyl cyanide are also the largest molecules yet detected in any star-forming region
#Computer recreates powerful solar flares ETH Zurich rightoriginal Studyposted by Barbara Vonarburg-ETH Zurich on September 26 2014physicists have used computers to model solar explosions
The computer model demonstrates that the shorter the interval between two explosions in the solar atmosphere the more likely it is that the second flare will be stronger than the first one. he agreement with measurements from satellites is strikingwrite the researchers from ETH Zurich
Hans Jurgen Herrmann a professor at the Institute for Building materials says solar flares were not the original focus of the work.
Similar patterns to those in solar flares can also be found in earthquakes avalanches or the stock market. olar explosions do not of course have any connection with stock exchange ratessays Hermann
In the case of solar flares the build up of magnetic energy is emitted in sudden bursts. The sun consists of hot plasma made of electrons and ions.
Magnetic field lines extend from the solar surface all the way into the corona. Moving and twisting bundles of field lines form magnetic flux tubes.
When two tubes intersect they merge (physicists call this reconnection) causing an explosion that gives off large quantities of heat and electromagnetic radiation.
The affected solar area lights up as a solar flare. The radiation extends across the entire electromagnetic spectrum from radio waves and visible light to X-rays and gamma rays.
Observations suggest that the solar flares size distributions show a certain degree of regularity statistically speaking. vents can be arbitrarily large
he system is turbulentthe magnetic field lines in the corona do not move in a random pattern
However calculations based solely on plasma turbulence were also unable to reproduce the occurrence of solar flares in full.
and reached a breakthrough. e have been able to reproduce the overall picture of how solar flares occurthe researcher says.
which control the occurrence of solar flares. Demonstrating such temporal-energetic correspondences is the first step towards a prediction model.
