ANIMATION For animals in the Arctic, life is a balancing act. Seasonal cues, such as warmer spring temperatures or cooler temperatures in the fall, tell animals when to migrate, when to mate, and when and where to find food. Predators and prey, birds and mammals alike follow this natural schedule, […]

As glaciers flow outward from the Greenland Ice Sheet, what lies beneath them offers clues to their role in future ice thinning and sea-level rise contribution. Outlet glaciers are rivers of ice flowing within the cracks of the bedrock and draining into the surrounding sea. They retreat and start to […]

ANIMATION The Hubble Space Telescope turned 30 this year, and for the occasion, it’s sharing a present with you. NASA has just released dozens of newly processed Hubble images featuring 30 dazzling galaxies, sparkling star clusters, and ethereal nebulae. And there’s something extra special about these 30 celestial gems: All of them can be […]

New data from the NASA/ESA Hubble Space Telescope provides further evidence for tidal disruption in the galaxy NGC 1052-DF4. This result explains a previous finding that this galaxy is missing most of its dark matter. By studying the galaxy’s light and globular cluster distribution, astronomers have concluded that the gravitational […]

This graph shows how the amount of water in the atmosphere of Mars varies depending on the season. During global and regional dust storms, which happen during southern spring and summer, the amount of water spikes.

Taken July 17, 2018, at Little Kenosee Lake, Saskatchewan, Canada, this photo shows the tiny green streaks below STEVE. Neil Zeller, photographer and co-author on the paper, commented “STEVE was bright and powerful for a full hour that night.” Credit: Copyright Neil Zeller In 2018, a new aurora-like discovery struck […]
