Observation of super-Alfvénic slippage of reconnecting magnetic field lines on the Sun [0.03%]
观测到太阳上重新连接磁力线的超阿尔文滑移现象

Juraj Lörinčík et al.
Slipping motions of magnetic field lines are a distinct signature of three-dimensional magnetic reconnection, a fundamental process driving solar and stellar flares. While being a key prediction of numerical experiments, the rapid super-Alf...
A luminous and young galaxy at z = 12.33 revealed by a JWST/MIRI detection of Hα and [O iii] [0.03%]
詹姆斯韦伯空间望远镜中红外仪器探测到的氢-alpha和氧-third线所揭示的一个光亮年轻的红移为12.33的星系

Jorge A Zavala et al.
The James Webb Space Telescope has discovered a surprising population of bright galaxies in the very early Universe (≲500 Myr after the Big Bang) that is hard to explain with conventional galaxy-formation models and whose physical properti...
Multiwavelength constraints on the origin of a nearby repeating fast radio burst source in a globular cluster [0.03%]
多波段研究揭示重复快速射电暴处于球状星团中
Aaron B Pearlman,Paul Scholz,Suryarao Bethapudi et al.
Aaron B Pearlman et al.
The precise origins of fast radio bursts (FRBs) remain unknown. Multiwavelength observations of nearby FRB sources can provide important insights into the enigmatic FRB phenomenon. Here we present results from a sensitive, broadband X-ray a...
Evidence of a 4.33 billion year age for the Moon's South Pole-Aitken basin [0.03%]
月球南极-艾肯盆地形成年龄为43亿年的证据
K H Joy,N Wang,J F Snape et al.
K H Joy et al.
The Moon's farside South Pole-Aitken (SPA) basin is the largest and oldest visible impact basin in the inner Solar System. Determining the timing of this catastrophic event is key to understanding the onset of the lunar basin-forming epoch,...
Contribution of Ryugu-like material to Earth's volatile inventory by Cu and Zn isotopic analysis [0.03%]
基于Cu和Zn同位素分析的小行星龙宫物质对地球挥发份库存的贡献
Marine Paquet,Frederic Moynier,Tetsuya Yokoyama et al.
Marine Paquet et al.
Initial analyses showed that asteroid Ryugu's composition is close to CI (Ivuna-like) carbonaceous chondrites -the chemically most primitive meteorites, characterized by near-solar abundances for most elements. However, some isotopic signat...

The isotopic composition of meteorites and terrestrial planets holds important clues about the earliest history of the Solar System and the processes of planet formation. Recent work has shown that meteorites exhibit a fundamental isotopic ...
A supra-massive population of stellar-mass black holes in the globular cluster Palomar 5 [0.03%]
帕洛玛5球状星团中的超质量恒星级黑洞群体
Mark Gieles,Denis Erkal,Fabio Antonini et al.
Mark Gieles et al.
Palomar 5 is one of the sparsest star clusters in the Galactic halo and is best-known for its spectacular tidal tails, spanning over 20 degrees across the sky. With N-body simulations we show that both distinguishing features can result fro...
Imprints of massive black-hole binaries on neighbouring decihertz gravitational-wave sources [0.03%]
质量巨大黑洞双星对邻近的十赫兹引力波源的影响
Jakob Stegmann,Lorenz Zwick,Sander M Vermeulen et al.
Jakob Stegmann et al.
The most massive black holes in our Universe form binaries at the centre of merging galaxies. The recent evidence for a gravitational-wave (GW) background from pulsar timing may constitute the first observation that these supermassive black...
An estimate of the impact rate on Mars from statistics of very-high-frequency marsquakes [0.03%]
基于非常高频火星地震的统计估算火星撞击率
Géraldine Zenhäusern,Natalia Wójcicka,Simon C Stähler et al.
Géraldine Zenhäusern et al.
The number density of impact craters on a planetary surface is used to determine its age, which requires a model for the production rate of craters of different sizes. On Mars, however, estimates of the production rate of small craters (
Resolved ALMA observations of water in the inner astronomical units of the HL Tau disk [0.03%]
ALMA探测HL Tau盘内部天文单位中水的观测结果
Stefano Facchini,Leonardo Testi,Elizabeth Humphreys et al.
Stefano Facchini et al.
The water molecule is a key ingredient in the formation of planetary systems, with the water snowline being a favourable location for the growth of massive planetary cores. Here we present Atacama Large Millimeter/submillimeter Array data o...
