NASA的斯皮策,TESS发现了可能被火山覆盖的地球大小的系外行星
天文学家发现了一颗地球大小的系外行星,或者说是太阳系以外的行星,它可能布满了火山。
Maestro Piotr Gajewski conducts the National Philharmonic in the world premiere performance of Henry Dehlinger’s “Cosmic Cycles,” in this photo from Thursday, May 11, 2023, as an enhanced color image of Jupiter is displayed above. “Cosmic Cycles: A Space Symphony” is a collaboration between composer
在梅西耶84星系(M84)的热气中有一个“H”形结构。来自银河系中心超大质量黑洞的喷流在高温下产生了相反方向的空洞。NASA钱德拉X射线天文台的X射线数据(以粉红色显示)与VLA的无线电数据(以蓝色显示)相结合,显示了这一点。
This new image from NASA’s Hubble Space Telescope shows interacting galaxies known as AM 1214-255. These galaxies contain active galactic nuclei, or AGNs. An AGN is an extraordinarily luminous central region of a galaxy. Its extreme brightness is caused by matter whirling into a supermassive black h
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
A menagerie of interesting astronomical finds are visible in this image from the NASA/ESA Hubble Space Telescope. In addition to several large elliptical galaxies, a ring-shaped galaxy is lurking on the right of the image. A pair of bright stars are also visible at the left of the image, notable for
NASA的詹姆斯·韦伯太空望远镜已经开始揭示宇宙历史上迄今为止遥不可及的形成时期:星系的形成和聚集。天文学家称之为红移7.9的距离,即大爆炸后仅6.5亿年,首次证实了由七个星系组成的原星团。
天文学家已经确定,超新星爆炸对行星及其大气构成了另一种威胁。这一结果来自于NASA钱德拉X射线天文台和其他望远镜对30多颗超新星进行的X射线观测分析。
天文学家正在庆祝NASA的哈勃太空望远镜发射33周年,并拍摄了一张附近恒星形成区域NGC 1333的空灵照片。该星云位于英仙座分子云中,距离地球约960光年。
