TONIGHT! #ScienceUnderSiege

in the #arXiv Ukrainian Wartime Astronomy and its Prospects by Danilo Albergaria and co-authors arxiv.org/abs/2509.26510 🧪🔭

Hey planetary science PhD graduaters: I know thinking about applying to postdocs this year seems daunting, so I am here to remind you that we have some REALLY GOOD prize fellowship at Caltech. Come work with me. Or Katherine. Or Heather. Or Konstantin. Or someone. Seriously. These are good. 🔭🪐

C215 est de retour à Saclay ?! 👀 Le street artist est revenu au @cea.fr pour une journée exceptionnelle. On vous dévoile la nouvelle fresque qui a rejoint les murs de l'INSTN. Marie Curie, pionnière scientifique, prix Nobel et professeure a retrouvé le chemin de l'école sur nos murs 🤩

We now know that Venus does have lava tubes - and they're weird.

🔴 Le récap' de la semaine est en ligne !

My favourite quote from George came when I suggested that some methods used for studying the cosmic microwave background could be applied to the distribution of galaxies. His response was "Galaxies are shit"... telescoper.blog/2025/09/26/r...

Tech millionaire turned longevity pioneer Bryan Johnson devotes more than 6 hours a day to trialling different methods to turn back the clock. Can the rest of us learn anything from his radical approach?

So was cold fusion real after all? A new paper in Nature absolutely doesn't imply that. But it's interesting anyway. My latest column for @thenewworldmag.bsky.social www.thenewworld.co.uk/philip-ball-...

L’astrophysicienne Marie-Anne Bizouard de l’ @obscoteazur.bsky.social explique en quoi la découverte des ondes gravitationnelles constitue une nouvelle fenêtre sur l’Univers.

There’s a new comet in the sky, although, as of Friday morning, it was not yet officially confirmed. SWAN25B is best positioned for observers in the Southern Hemisphere. Because it’s so close to the sun, it will be tricky to spot. #comet #astronomy earthsky.org/space/new-co...

14 septembre 2015 : la collaboration internationale Ligo/Virgo capte le tout premier signal d’ondes gravitationnelles, infime déformation de l’espace-temps prédite par Einstein et qui signe alors la fusion de deux trous noirs. L’astrophysicienne Marie-Anne Bizouard explique en quoi cette découver...

Le télescope spatial JWST a mesuré le spectre de la comète Hale-Bopp à une distance de... 46 unités astronomiques !

Next #SETILive: Life in Titan’s Ocean? TODAY, 4 September, 11:00 am PDT Could Saturn’s largest moon, Titan, harbor life? A new study led by @aaffholder.bsky.social suggests that it might—but only in the tiniest amounts, making it incredibly hard to find. 🧪 🔭 👩‍🔬

A Primordial Black Hole? There's a recent paper on arXiv with the title A direct black hole mass measurement in a Little Red Dot at the Epoch of Reionizationon by Juodžbalis et al. that is causing a lot of interest. The paper is here and the abstract is: There is a discussion of this in the…

Primordial Black Holes in Cosmological Simulations – Update Just time for a quick update about a paper that I posted about at the start of the summer, when it appeared on arXiv. At that time it had already gained a bit of traction in the media, e.g. here. Well, the paper is now published in the…

Here Jason (@astrowright.bsky.social) elaborates on how Avi’s pseudoscientific and self-aggrandizing promotion of the idea that 31/Atlas is an alien artifact (never believable in the first place) have been definitively shown to be wrong. 🧪🔭 sites.psu.edu/astrowright/...

It is with great sadness that we learn of the passing of Rainer Weiss, one of the fathers of gravitational wave research, founder of @ligo.org and Nobel Prize laureate in physics for the detection of gravitational waves in 2017. Photo credits: MIT/Bryce Vickmark

If you want to understand why RFK Jr. has halted $500 million in funding for mRNA vaccine development, look no further than Synthroid and herbal medicines. It has nothing to do with following better science and everything to do with alt med beliefs. sciencebasedmedicine.org/what-do-mrna...

It's (well past) time to impeach RFK Jr. You can sign a petition to help! Also: (very) old issues of Scientific American magazine were very, very odd. badastronomy.beehiiv.com/p/impeach-rf... 🔭🧪

Jupiter’s moon Ganymede could be a vast dark matter detector, and upcoming space missions might be able to spot distinctive dark matter craters on its ancient surface.

Really great day looking for early Paleozoic echinoderms and trilobites on Anticosti Island. The fossil specimens collected this day were marine animals living in the immediate aftermath of the end-Ordovician mass extinction event ~443 million years ago 🧪

Working with Peter on this book has been especially rewarding, meaningful...and therapeutic. We had no idea just how sadly relevant #ScienceUnderSiege would be when we set out to write the book a year and a half ago.

100% d'accord avec ma collègue :) www.futura-sciences.com/planete/actu...
