Paleontologists have identified a new species of iguanodontian dinosaur from a partial skeleton found in the Cedar Mountain Formation, Utah, the United States. Life reconstruction of Iani smithi. Image credit: Jorge Gonzalez. The new dinosaur lived in what is now the United States during the mid-Cretaceous period, approximately 99 million years ago. Named Iani smithi, the species was an early-diverging ornithopod, a group of mostly bipedal herbivores...

In this Hubble image, the disk of the jellyfish galaxy JO206 is trailed by long tendrils of bright star formation that stretch towards the bottom right of the image, just as jellyfish trail tentacles behind them. The color image was made from separate exposures taken in the visible, ultraviolet and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). The image is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
