Explanation: The large stellar association cataloged as NGC 206 is nestled within the dusty arms of the neighboring Andromeda galaxy along with the galaxy’s pinkish star-forming regions. Also known as M31, the spiral galaxy is a mere 2.5 million light-years away. NGC 206 is found at the center of this sharp and detailed close-up of
On a cool November morning, low clouds traced the branching valleys of the Appalachian Plateau and the Cumberland River. By afternoon, they had faded, leaving clear skies over the autumn landscape. The change is visible in this pair of images from November 8, 2026. The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Terra satellite acquired the left image

The impending collision was clear from audio calls and on big screens in the control centre in Madrid. “They worked. We

Written by Alex Innanen, Atmospheric Scientist at York University Earth planning date: Friday, Oct. 9, 2026 Happy New Mars Year! We mark the start of a new year on Mars at the beginning of the northern hemisphere spring, or the vernal equinox. We then keep track of the seasons by counting degrees of solar longitude
Winter near the Antarctic Circle brings months of frozen darkness, when sea ice chokes ocean waters and many of its denizens hunker down to ride out the harsh conditions. But as winter began to release its icy grip, an uncommonly clear satellite image revealed that part of this remote realm was still very much awake,
