Direct dating of gold by radiogenic helium

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).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.

And what stands out in these findings is the apparent strength of the magnetic field involved, for the Faraday rotation is extreme, among the largest ever measured in a radio source.The outer part of the image shows the reflected light on the dust disc, as observed in 1996 with the ADONIS instrument on ESO’s 3.6 m telescope; the inner part is the innermost part of the system, as seen at 3.6 microns with NACO on the Very Large Telescope.The newly detected source is more than 1000 times fainter than Beta Pictoris and aligned with the disc. Consider this star, then, a conveniently close laboratory for the study of how stellar systems form.With launch scheduled for tomorrow, Pic Sat is a nanosatellite built on a Cube Sat platform, one containing a 5 cm telescope destined for the study of β Pic.Pic Sat will use no more than 5 watts of power in the attempt to view a transit of β Pic b.
