Direct dating of gold by radiogenic helium

While the satellite will be operated from Meudon in France, a facility of the Paris Observatory, Pic Sat uses radio amateur bands for communication.Citizen scientists therefore take note: The Pic Sat team is opening the door for radio amateurs worldwise to collaborate in tracking the satellite, receiving data and relaying them to the Pic Sat database over the Internet.

But there are other possibilities, as Arecibo staff astronomer Andrew Seymour comments, referring to the FRB observations at higher radio frequencies than before: “We developed a new observing setup at the Arecibo Observatory to do this, and our colleagues from Breakthrough Listen at the Green Bank Telescope confirmed the results with observations at even higher radio frequencies.What’s more, the polarization properties and shapes of these bursts are similar to radio emission from young, energetic neutron stars in our galaxy.Given the distance between the source and us, researchers have calculated that each burst throws as much energy in a single millisecond as our Sun releases in an entire day.And as we learn in the latest issue of , an international team has been able to show that the bursts from FRB 121102 are highly polarized, allowing insights into the environment from which it sprang.It is 9h28m AM here in Sriharikota, 4h58m AM in Paris. Fast Radio Bursts (FRBs) continue to intrigue us given their energy levels.

You may recall FRB 121102, which was revealed at a press conference almost exactly one year ago to be located in a radio galaxy some 3 billion light years away.Indeed, the observed structure of planetesimal belts here is a possible indication of smaller planets we have not yet observed.While β Pic b was discovered by direct imaging, there are interesting transit possibilities that are now being explored by scientists at the Paris Observatory and the Centre National De La Recherche Scientifique (CNRS).A transit here would last only a few hours, but it would give us information about the size of the planet, the extent of its atmosphere and its chemical composition.The beginning of a transit will trigger an alert to the 3.6 meter telescope at the European Southern Observatory’s La Silla site, where the HARPS (High Accuracy Radial velocity Planet Searcher) spectrograph can be used to study the event.Modular methodologies to the rescue as we are reminded once again that simple resources like Cube Sats are capable of world-class science.
