NASA的罗曼和ESA的欧几里得将联手研究暗能量
一台名为欧几里得的新太空望远镜将于7月发射，这是ESA在美国宇航局的资助下完成的一项任务，旨在探索宇宙膨胀加速的原因，即暗能量。到2027年5月，NASA的南希·格雷斯·罗曼太空望远镜将与欧几里得一起，以前所未有的方式探索这个谜题。

哈勃望远镜瞥见一个闪烁的星团
The teeming stars of the globular cluster NGC 6544 glisten in this image from the NASA/ESA Hubble Space Telescope. This cluster of tightly bound stars lies more than 8,000 light-years away from Earth and is, like all globular clusters, a densely populated region of tens of thousands of stars. This image of NGC 6544 combines data from two of Hubble’s instrume...
哈勃太空望远镜观测到一个闪烁的星团
The densely packed globular cluster NGC 6325 glistens in this image from the NASA/ESA Hubble Space Telescope. This concentrated group of stars lies around 26,000 light-years from Earth in the constellation Ophiuchus. Globular clusters like NGC 6325 are tightly bound collections of stars with anywhere from tens of thousands to millions of members. They can be...
中子星碰撞
Two neutron stars begin to merge in this illustration, blasting a jet of high-speed particles and producing a cloud of debris. These gamma-ray bursts (GRBs) are the most powerful events in the universe. Scientists think these kinds of events are factories for a significant portion of the universe’s heavy elements, including gold. They based their estimates o...
哈勃发现了一个多代星团
This image from the NASA/ESA Hubble Space Telescope shows the globular star cluster NGC 2419. Globular clusters are both beautiful and fascinating. They are spherical groups of stars that orbit the center of a galaxy, and in the case of NGC 2419, that galaxy is our own Milky Way. NGC 2419 is around 300,000 light-years from the solar system, in the constellat...
詹姆斯·韦伯太空望远镜揭示了仙后座A中从未见过的细节
NASA詹姆斯·韦伯太空望远镜的一张新的中红外图像显示了从地球上看到的340年前的超新星遗迹仙后座A（Cas A）。Cas A是我们银河系中已知的最年轻的大质量恒星爆炸残骸。
国际空间站的星轨
Stars leave streaks of light in concentric circles in this March 16, 2012, view from the International Space Station. To create this composite long exposure, NASA astronaut Don Pettit combined multiple 30-second exposures from a mounted camera on the space station into one image. The orbiting laboratory travels 5 miles per second, traveling around our planet...
NASA的詹姆斯·韦伯太空望远镜拍摄到罕见的超新星前奏曲
沃尔夫-拉叶星是已知的最明亮、质量最大、可探测时间最短的恒星之一，这颗罕见的恒星是NASA詹姆斯·韦伯太空望远镜于2022年6月首次观测到的恒星之一。韦伯用其强大的红外仪器以前所未有的细节展示了这颗名为WR 124的恒星。这颗恒星位于1.5万光年外的人马座。
