Galaxy clusters magnify background objects through strong gravitational lensing. Typical magnifications for lensed galaxies are factors of a few but can also be as high as tens or hundreds， stretching galaxies into giant arcs. Individual stars can attain even higher magnifications given fortuitous alignment with the lensing cluster. Recently， several individual stars at redshifts between approximately 1 and 1.5 have been discovered， magnified by factors of thousands， temporarily boosted by microlensing. Here we report observations of a more distant and persistent magnified star at a redshift of 6.2 ± 0.1， 900 million years after the Big Bang. This star is magnified by a factor of thousands by the foreground galaxy cluster lens WHL0137–08 ， as estimated by four independent lens models. Unlike previous lensed stars， the magnification and observed brightness have remained roughly constant over 3.5 years of imaging and follow-up. The delensed absolute UV magnitude， −10 ± 2， is consistent with a star of mass greater than 50 times the mass of the Sun. Confirmation and spectral classification are forthcoming from approved observations with the James Webb Space Telescope.

最遥远的恒星，距离地球280亿光年，为何光传到地球只用129亿年？
当时的天文学家十分愤怒，因为哈勃望远镜作为珍贵的观测资源，天文学家们都在排着队等着使用这个望远镜来完成科研项目，可却要用来拍摄最暗的天区，在他们看来这无疑是在浪费资源，根本不会有什么成果。

MIT发现让AI变聪明的秘密，竟然和人类一模一样
你有没有发现，你让AI读一篇长文章，结果它读着读着就忘了前面的内容？ 你让它处理一份超长的文档，结果它给出来的答案，牛头不对马嘴？ 这个现象，学术界有个专门的名词，叫做上下文腐化。 这也是目前AI的通病：大模型的记忆力太差了，文章越长，模型越傻！

Isotope abundance ratios have an important role in astronomy and planetary sciences， providing insights into the origin and evolution of the Solar System， interstellar chemistry and stellar nucleosynthesis. In contrast to deuterium/hydrogen ratios， carbon isotope ratios are found to be roughly constant in the Solar System， but do vary on galactic scales with a 12C/13C isotopologue ratio of around 68 in the current local interstellar medium. In molecular clouds and protoplanetary disks， 12CO/13CO ratios can be altered by ice and gas partitioning， low-temperature isotopic ion-exchange reactions and isotope-selective photodissociation9. Here we report observations of 13CO in the atmosphere of the young， accreting super-Jupiter TYC 8998-760-1 b， at a statistical significance of more than six sigma. Marginalizing over the planet’s atmospheric temperature structure， chemical composition and spectral calibration uncertainties suggests a 12CO/13CO ratio of。
