A nice summary of our paper that came out last month!
A study in @NatureAstronomy reveals that Voyager 2's 1986 flyby of Uranus — which formed much of the scientific understanding of the planet —might have occurred under rare conditions, leading to a potentially skewed understanding of the planet's magnetosphere. @NaturePortfolio

Scientists are mining the mysteries of Uranus. (Yeah, we said it.) Almost 40 years ago, @NASAVoyager got a close look at Uranus for the first time—but a new analysis is helping explain a few of the planet's unexplained oddities: go.nasa.gov/3UPkZrD

When Voyager 2 flew past Uranus in 1986, the planet's magnetosphere seemed super weird. There was no plasma, and the radiation belts were mega intense. Now we might know why, because of rare solar activity hitting the planet. Story by me @nytimes nytimes.com/2024/11/11/scien…

My excellent friend @spaceJamieJ discovered that lots of Uranus's mysterious behaviour that we've talked about for decades, based on Voyager 2s flyby, happened during really extreme solar wind conditions. It's out today here: nature.com/articles/s41550-0… . May be some news coverage.

A reanalysis of the 1986 Voyager 2 flyby of Uranus shows that it occurred during an extreme compression of the planet’s magnetosphere by the solar wind. This would have had significant effects on the measurements made during the flyby. @spaceJamieJ et al.: nature.com/articles/s41550-0…

When @NASAVoyager 2 flew by Uranus in 1986, it provided our first — and, so far, only — close glimpse of this strange outer planet. Scientists are still analyzing the data from that flyby, and one researcher recently found a surprise: go.nasa.gov/3YIaLKD

Check out my 3 talks at AGU this year: SM53C-04: Photoionization at Mercury's Exosphere SM43B-01: Reconnection at Saturn P52B-09: Neptune's pole-on magnetosphere Can I now call myself a collector of planets? 😂

A great paper I had the pleasure to co-author, led by Diego Janches @NASAGoddard
How do meteoroids shape exospheres on airless bodies? Janches et al. review @MESSENGER2011 observations of #Mercury and @NASAMoon LADEE observations of the #Moon dynamical models to explore this complex question! Read on: link.springer.com/article/10…
Ever wondered what processes produce Mercury's sodium exosphere? Check out the schematic from a paper I led that has now been published in GRL which discusses the exosphere and the role of photoionization. Paper link: agupubs.onlinelibrary.wiley.… @ExploreMercury @NASAJPL @LASPatCU

I need to permit myself a little self-promotion.... my first first-author paper has recently been accepted to JGR Space Physics! Typeset and formatted version coming soon :D agupubs.onlinelibrary.wiley.… #Jupiter #EuropaMoon

Temperature isn't the only thing changing during the seasons...@spaceJamieJ et al. analyzed how the amount of sodium lost due to photoionization varies throughout a year on #Mercury using @INSU_CNRS #Themis telescope and @MESSENGER2011 data. Read on: doi.org/10.1029/2021GL092980

@spaceJamieJ et al. identified enhancements of neutral particles from Mercury's exosphere at high altitudes in MESSENGER data. This can only be explained by a micrometeroid impacting the surface of #Mercury! #AGU20
