What is OPAL? OPAL (Outer Planet Atmospheres Legacy) is a project to obtain long time baseline observations of the outer planets in order to understand their atmospheric dynamics and evolution as gas giants. The yearly observations from OPAL throughout the remainder of Hubble’s operation will provide an important legacy of time-domain images for use by planetary scientists. Viewers might notice that some of the images of the same planets appear to be different colors. This is due to the fact that over the years, from Voyager to Hubble, many different instruments, and many different filters have been used.

Top New Science Podcasts: Tooth Enamel And Decay, Heart Attack Patches, ‘Hot Neptune Deserts’ (Nature)
On this week’s podcast, how the molecular structure of tooth enamel may impact decay, adhesive patches to heal heart attacks, and a mysterious planetary core from a half-formed gas giant.
In this episode:
00:46 Unravelling tooth enamel
Researchers have been looking into the structure and composition of enamel in an effort to better understand tooth decay. Research Article: DeRocher et al.
07:02 Research Highlights
An adhesive patch to help heal heart-attacks, and a new technique to inspect the structure of 2D ‘wonder materials’. Research Highlight: A healing patch holds tight to a beating heart; Research Highlight: A snapshot shows off super-material only two atoms thick
09:21 Unusual planet
In the region close to stars known as the ‘hot Neptune desert’ planets of Neptune’s size are rarely found, but this week scientists have uncovered one and are trying to untangle its mysteries. Research Article: Armstrong et al.
14:52 Briefing Chat
We take a look at some highlights from the Nature Briefing. This time we talk about the pitfalls of using CRISPR in human embryos, and renaming of moon craters inadvertently named after Nazi scientists. Nature News: CRISPR gene editing in human embryos wreaks chromosomal mayhem; Prospect Magazine: Astronomers unknowingly dedicated moon craters to Nazis. Will the next historical reckoning be at cosmic level?
