Mabukuwa ndi a ofufuza okha, si a Local Solar System Foundation. Zomwe zonse zidasindikizidwa kudzera pa * Zidziwitso za Sayansi *, kuti aliyense angathe kuziwerenga mokwanira. Zithunzizi ndi zathu; chonde werengani masambawo okha musanagwiritse ntchito mawu awo.

Zikhalidwe ndi mmene tikudziwa kuti usiku akutha. Ndi mmenenso tidzadziwa pamene adzabweranso.

Kuwerengera nyanja

Kugwiritsa ntchito photometry yosiyana ya nyanja yonse kuti ifufuze momwe mafumu a usiku amawononga dzuwa la usiku m’madera akumidzi Andreas Jechow, Franz Hölker & Christopher C. M. Kyba. Scientific Reports 9, 1391 (2019).
