JWST's Top 3 Breakthrough Discoveries
Since its launch, the James Webb Space Telescope (JWST) has made significant breakthroughs in cosmology and exoplanet research, including discovering early universe galaxies, observing planet formation, and analyzing exoplanet atmospheres.
The top 3
- 最早星系挑战宇宙模型: JWST观测到大爆炸后3-4亿年就已形成的巨大星系,如JADES-GS-z14-0,这些星系比现有宇宙学模型预测的要早得多且更复杂.
- 揭示行星形成奥秘: JWST以前所未有的光谱分辨率绘制了原行星盘的化学成分图,在Fomalhaut等恒星周围发现了水蒸气和复杂有机分子,为行星形成提供了线索.
- 系外行星大气革命性分析: JWST利用其红外能力,革命性地分析了系外行星大气,在K2-18 b等行星上探测到甲烷、二氧化碳和水蒸气,甚至初步发现了二甲基硫(DMS).
