Development in Converting CO2 to Fuel

In a new study in Proceedings of the National Academy, scientists from Berkeley Lab have created a method to convert CO2 into multicarbon fuels and alcohols using “record-low inputs of energy.” Peidon Yang, on the research team, is quoted: “What we are reporting here is much more challenging. We discovered a catalyst for carbon dioxide reduction operating at high current density with a record low overpotential that is about 300 millivolts less than typical electrocatalysts.” (Sep 18, 2017)

Earth Could be Visible to Nine Known Exoplanets

Scientists have found many planets outside our solar system by watching them transit across their home stars. Now researchers at Queen’s University Belfast and the Max Planck Institute for Solar System Research have thought about the obverse problem: Could planets be detected by transiting across our own sun. The answer: At least nine known exoplanets would have a good opportunity to detect a planet orbiting our sun. (Sep 10, 2017)

Another Star with Multiple Earth-Sized Planets

Using telescopes in Hawaii and Chile, scientists have that the star Tau Ceti (12 light-years from Earth) and is orbited by four "super-Earths." The smallest of these newly found planets is almost twice the size of Earth. Two of the planets are thought to be in the...

European Gravitational Wave Detector Is Up and Running

The massive (3 km arms) European gravitational wave detector, known as Virgo, is up and running again. Its data will be shared with data from LIGO in the USA to more accurately detect gravitational waves, as may occur when black holes interact and alter space. (Aug....

Possible First Exomoon Discovered

Scientists have found many exoplanets, planets outside of our solar system (more than 3,000 so far). But the report here is of the potential first exomoon discovered using the Kepler Space Telescope. The presumptive moon is in orbit around an exoplanet the size of Jupiter about 4000 light years away. (July 28, 2017)
