Слишком хороший признак: как звёзды, галактики и квазары научили меня не верить графикам
На Kaggle завершился шестой эпизод Playground Series , и тема на этот раз была астрономическая: по горстке чисел определить, что перед нами: звезда, галактика или квазар. По этому выпуску я решил собрать почти исчерпывающий разбор EDA.

Slides from my #SDSS talk today on designing an Intermediate #rstats course:
kbodwin.github.io/Talks-and-Presentations/SDSS_2025/Intermediate_R.html
(Skip to the end if you want to get on a mailing list for sharing the materials we're making!)
Thank you to all who attended an early Friday talk and asked great questions! 🤩

Great paper by Mirjam Guesgen for @Motherboard @VICENews on the discovery of the Big Ring
On the proximity of this structure with the Giant Arc:
“Identifying two extraordinary ultra-large structures in such close configuration raises the possibility that together they form an even more extraordinary cosmological system.” @morninglopez (co-author of the discovery)https://www.vice.com/en/article/m7bwea/scientists-discover-big-ring-ultra-large-structure-in-space

Just finished adding support for texture arrays in particle cloud objects. This is what SDSS looks like when adding a texture array with ~30 random galaxies.

A new instrument is joining the fleet at the #LasCampanas Observatory in Chile’s #Atacama Desert. It will map our neighboring #galaxies — including those only visible from the southern hemisphere — on a larger scale than ever before. This galactic cartographer, called the #LocalVolumeMapper, is the latest addition to the Sloan Digital Sky Survey (#SDSS): https://impact.sloan.org/the-sloan-digital-sky-survey-has-entered-chiles-atacama-desert-e4542e2bf0fe
