The galaxy known as NGC 5907 stretches wide across this image. Appearing as an elongated line of stars and dark dust, the galaxy is categorized as a spiral galaxy just like our own Milky Way. In this new image from the NASA/ESA Hubble Space Telescope, we don’t see the beautiful spiral arms because w […]
Seen here in incredible detail, thanks to the NASA/ESA Hubble Space Telescope, is the starburst galaxy formally known as PLCK G045.1+61.1. The galaxy, which appears as multiple reddish dots near the center of the image, is being gravitationally lensed by a cluster of closer galaxies, also seen in th
Looking deep into the universe, the NASA/ESA Hubble Space Telescope catches a passing glimpse of the numerous arm-like structures that sweep around this barred spiral galaxy, known as NGC 2608. Appearing as a slightly stretched, smaller version of our Milky Way, the peppered blue and red spiral arms
美国宇航局/欧空局哈勃太空望远镜的最新结果表明，早期宇宙中第一批恒星和星系的形成比之前认为的要早。欧洲天文学家还没有发现第一代恒星的证据，也就是所谓的星族Ⅲ，那时宇宙只有5亿年的历史。 探索最早的星系仍然是现代天文学的重大挑战。我们不知道宇宙中最初的恒星和星系是何时或如何形成的。这些问题可以通过哈勃太空望远镜的深度成像观测来解决。哈勃望远镜可以让天文学家将宇宙回溯到大爆炸5亿年内。 美国宇航局/欧空局哈勃太空望远镜的最新结果表明，早期宇宙中第一批恒星和星系的形成比之前认为的要早。欧洲天文学家小组没有发现第一代恒星的证据，也就是第三代恒星，那时宇宙还不到10亿年。这个艺术家的印象呈现了早期的宇宙
Almost like snowflakes, the stars of the globular cluster NGC 6441 sparkle peacefully in the night sky, about 13,000 light-years from the Milky Way’s galactic center. Like snowflakes, the exact number of stars in such a cluster is difficult to discern. It is estimated that together the stars have 1.
Nancy Grace Roman (1925-2018), NASA’s first chief astronomer, is known as the ‘Mother of Hubble.’ In a time when women were discouraged from studying math and science, Roman became a research astronomer and was instrumental in taking NASA’s Hubble Space Telescope from an idea
Dark matter, although invisible, makes up most of the universe’s mass and creates its underlying structure. Dark matter’s gravity drives normal matter (gas and dust) to collect and build up into stars and galaxies. Although astronomers cannot see dark matter, they can detect its influence by observi
NASA为庆祝哈勃太空望远镜30年来揭开太空之美和神秘之处，近日公布了一幅令人震惊的新图像，展示了邻近星系的一场恒星诞生的风暴。 在这张哈勃拍摄的照片中，巨大的红色星云(NGC 2014)和它较小的蓝色邻居(NGC 2020)是位于16.3万光年之外的银河系卫星星系大麦哲伦星云中一个巨大的恒星形成区域的一部分。这幅图片之所以被称为“宇宙暗礁”是因为它看起来像海底世界。 为纪念哈勃太空望远镜观测太空30周年，NASA日前发布了一幅彩色图像，这幅图像酷似一个充满恒星的海底世界的宇宙版本。在这张哈勃拍摄的照片中，巨大的红色星云(NGC 2014)和它较小的蓝色邻居(NGC 2020)是位于16.3万
现在你看到了，现在看不到了。 天文学家认为太阳系外的一颗行星现在似乎消失了。尽管这在科幻小说中经常发生，比如超人的故乡氪星爆炸，但天文学家们正在寻找一个合理的解释。 一种解释是，与其说是2004年首次拍摄的全尺寸行星物体，不如说是是由围绕着明亮的北落师门运行的两个大型天体碰撞产生的一个巨大的、不断膨胀的尘埃云。潜在的后续观察可能会证实这一非同寻常的结论。 “这些碰撞极其罕见，所以我们能看到这些碰撞的证据其实是一件大事” 图森市亚利桑那大学的安德拉斯·加斯帕尔说，“我们相信，我们在正确的时间、正确的地点，用美国宇航局的哈勃太空望远镜见证了这样一个不太可能发生的事件。” 这张图模拟了天文学家在研究
Human eyes can see only a small portion of the range of radiation given off by the objects around us. We call this wide array of radiation the electromagnetic spectrum, and the part we can see visible light. In this Hubble Space Telescope image, researchers revisited one of Hubble’s most iconi
