This painting depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds. Image credit: Donald E. Davis / NASA.

This Hubble image shows NGC 1947, a lenticular galaxy located some 40 million light-years away in the constellation Dorado. The color image of NGC 1947 was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This composite image shows both ALMA and SPHERE/VLT observations of the disk around GW Orionis. The ALMA image (blue) shows the disk’s ringed structure, with the innermost ring (part of which is visible as an oblong dot at the very center of the image) separated from the rest of the disk. The SPHERE observations (orange-red) allowed the astronomers to see for the first time the shadow of this innermost ring on the rest of the disk, which made it possible for them to reconstruct its warped shape.
