There is undeniable proof that water once existed on the planet Mars, a team of researchers has concluded in a series of 11 articles this week in a special issue of the journal Science.
A team of more than 100 scientists from numerous government agencies and universities, among them Mark Lemmon of Texas A&M Universitys College of Geosciences, co-wrote the articles. Lemmon was the principal author on one article and co-author on three others describing the work of Spirit and Opportunity, NASAs twin rovers that landed on Mars in January. The rovers landed in different locations on Mars and have been sending back data and images for the past 10 months.
The reports in Science focused on results from Opportunity, which is in a region of Mars called Meridiani Planum, although Lemmons article and one other described findings from both rovers regarding Mars atmosphere.

“Core-shell” clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient.
Whether in innovative high-tech materials, more powerful computer chips, pharmaceuticals or in the field of renewable energies, nanoparticles – smallest...
An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.
Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
