Science Talk – What Are Pulsar Planets? (2022) (spaceaustralia.com)
2022 marks the 30-year anniversary since the discovery of the first exoplanets, which happened to be orbiting a pulsar - one of the most unusual places we could find any planet. But what is a pulsar planet, and how did they get there?

Decoding Hera (destevez.net)
Hera is an ESA mission to the Didymos binary asteroid system. It will arrive there in December 2026 to study the asteroids and the effects of the impact of DART on Dimorphos. It was launched on October 7 from Cape Canaveral, exactly one week before Europa Clipper. In the same way as for Europa Clipper, Hera’s launch trajectory allowed me to track it with the Allen Telescope Array, starting approximately 90 minutes after launch.

Probing unknown unknowns: A new generation of telescopes (mappingignorance.org)
In recent decades, we’ve learnt huge amounts about the universe and its history. The rapidly developing technology of telescopes – both on Earth and in space – has been a key part of this process, and those that are due to start operating over the next two decades should push the boundaries of our understanding of cosmology much further.

Uranus' moon Miranda may have an ocean beneath its surface (phys.org)
A new study suggests Uranus' moon Miranda may harbor a water ocean beneath its surface, a finding that would challenge many assumptions about the moon's history and composition and could put it in the company of the few select worlds in our solar system with potentially life-sustaining environments.

The Event Horizon Telescope image might need a correction (academic.oup.com)
We propose that the ring structure found by the Event Horizon Telescope Collaboration (EHTC) as the black hole shadow of Sgr A* is an artefact caused by the bumpy point spread function (PSF) of the EHT 2017 data.

New JWST image may show first-ever brown dwarfs seen in another galaxy (beehiiv.com)
I am continually amazed at what the huge infrared space-based observatory JWST can do. I mean, I know its capabilities, and I know it has a huge mirror and fantastic ability to detect faint objects and see in incredible detail. I worked on Hubble long enough to know what these beasts can do!
