Nice discovery of a Saturn-mass microlens using the different perspectives of Earth and the GAIA telescope @gaiamission.bsky.social, and a nice animation to boot! arxiv.org/src/2601.000... www.science.org/doi/epdf/10....

The statue of Pasteur in Paris faces the Invalides where Napoleon is buried. This is apt as one fought germs, while the other fought Germans.

Excellent review paper on prospects for high-precision photometry of exoplanet systems with JWST by Sarah Millholland & Joshua Winn: www.pnas.org/doi/10.1073/...

Not only did this paper get published, but the author, Thomas Count Dracula, received the “Best Author of the Month” award. www.easpublisher.com/article/arti... h/t @bluewhalenews.bsky.social

Can an expert tell me if these error bars are accurate? arxiv.org/abs/2509.17454

Sorry Google and @wikipedia.org but this is not correct. Half of the Nobel prize was awarded to Penrose for the mathematical theory of black holes; the other half to Genzel & Ghez for their study of Sgr A*. (Thanks @nytgames.bsky.social Connections for alerting me to this!)

I just found the source of dark energy

Dr. Vera Rubin is the first Astronomer to be featured on a US Coin. Rubin is also the namesake of the new Rubin Observatory in Chile, honored for her discovery of evidence of dark matter in galaxies. rubinobservatory.org www.usmint.gov/news/press-r...

@plotastro.bsky.social This is a pretty visualization of hydrocarbon opacities in the atmosphere of Titan in arxiv.org/abs/2506.12144

Apparently we’ve been observing transiting exoplanets all wrong…

Wikipedia (English) features a planet system which we announced eight years ago.

Coldest giant *exoplanet* found to date, of course!

JWST has detected infrared light from the coldest giant planet found to date - and it orbits a white dwarf, causing the white dwarf to dip in brightness by ~50% every orbit: arxiv.org/abs/2504.16982

Here is my alternate model with uncertainties which goes through all of the data points at less than 1-sigma, save four.

The planet TOI-2015b hosts a planetary companion, TOI-2015c, but not the one previously announced. High-precision radial velocity (MAROON-X) + transit-timing variations (TESS+) reveal a planet companion near a second-order resonance with the transiting planet. arxiv.org/abs/2502.07074

Radial velocity and transit-timing variation graphs for TOI-2015b/c.
