With MeerKAT, Astronomers Peer at the Possibilities of Radio Imaging

by Santiago Flórez 11 March 202224 May 2022

Stunning images of the center of the Milky Way showcase technology and techniques that may be a starting point for more discoveries.

Two blocky telescope domes sit on snowy ground, and the band of the Milky Way arcs across the sky. The sky shades from navy at the top to green and orange at the horizon and is studded with stars.

Five Reasons Geoscience Should Care About Astronomy’s New Road Map

by Kimberly M. S. Cartier 5 November 202121 March 2022

The latest road map to U.S. astronomy’s next decade recommends a smaller space telescope, ground-based facilities, and an institutional effort to create an inclusive and equitable field.

The supergiant Betelgeuse glows red and orange against a dark, starry background. The star’s surface is mottled and emits a faint reddish glow representing its stellar wind. A dark cloud of dust partially obscures the star’s lower left region.
