We’re getting so many journal submissions from people who think ‘it kinda works’ is the standard to aim for.

A rare bit of good news from the US. House republicans seem to be pushing back against Trump's huge proposed cuts to science. NSF, NASA, NOAA - all look set to be near flat, or - for DOE - even a slight increase.

With the help of Gaia, some more cold Jupiters are found. They're at longer periods than the bulk of the known exoplanets, and at lower masses than most other known long-period planets. Wu+

JWST managed to determine the composition of three planets in the HR 8799 system. They found that the planets are all similarly enriched in heavy elements compared to the star, similar to Jupiter here. A bit surprising considering formation models. Ruffio+

For very hot exoplanets, people can now see how much of each element is there in the atmosphere and compare it to that of the star. In this case (WASP-189b), the rock-forming elements are like that of the star, as expected. The volatile elements (C,O) are lower. Sanchez+
