The orphan cloud is the blue umbrella-shaped part of this image, which is color-coded to show the X-ray part of the cloud in blue, the warm gas in red, and the visible region in white. Credit: Ge et al (2021) A scientifically mysterious, isolated cloud bigger than the Milky Way has been […]

Galaxies imaged in spectacular detail by Hubble’s Wide Field Camera 3 (WFC3). Credit: ESA/Hubble & NASA, T. Treu, Acknowledgment: J. Schmidt Clustered at the center of this image are six luminous spots of light, four of them forming a circle around a central pair. Appearances can be deceiving, however, as […]
