“Just add water!” said Robert Minchin, an Arecibo astronomer on the project, who explained that methanimine and hydrogen cyanide are two of the basic ingredients of life, because when combined with water they form glycine, the simplest amino acid, a building block of life on Earth.
The astronomy team, led by Arecibo astronomer Christopher Salter, announced this discovery today (Jan. 11) in a poster presented at the American Astronomical Society meeting in Austin. The Arecibo Observatory is managed by Cornell University for National Science Foundation.
The Arecibo astronomers focused on the distant galaxy Arp 220, an ultra-luminous starburst galaxy, because it forms new stars at a very high rate. They used the 305-meter, or 1,000-foot diameter, Arecibo radio telescope, the world’s largest and most sensitive, to observe the galaxy at different frequencies. In fact, for the first time in April 2007, they used the 800 megahertz wide-band mode of the main spectrometer to make these detections.
These molecules were found by searching for radio emission at specific frequencies. Each chemical substance has its own unique radio frequency and astronomers can in that way identify the different substances, much like people can be identified with their unique fingerprints.
“We weren’t targeting any particular molecule, so we didn’t know what we were going to find – we just started searching, and what we found was incredibly exciting,” said Tapasi Ghosh, an Arecibo astronomer.
“The fact that we can observe these substances at such a vast distance means that there are huge amounts of them in Arp 220,” said Emmanuel Momjian, a former Arecibo astronomer, now at the National Radio Astronomy Observatory in Socorro, N.M. “It is indeed very intriguing to find that the ingredients of life appear in large quantities where new stars and planets are born.”

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
