Direct dating of gold by radiogenic helium

Today, drawing on new observations from Arecibo and the Green Bank instrument in West Virginia, we learn something about the source of these bursts.

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.

We not only have a large gas giant in orbit here, but also evidence of cometary activity as seen in spectral data. Image: This composite image represents the close environment of Beta Pictoris as seen in near infrared light.

This very faint environment is revealed after a careful subtraction of the much brighter stellar halo.

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.
