By analyzing data on lunar craters provided by the Diviner instrument aboard the Lunar Reconnaissance Orbiter, scientists have made a fascinating discovery about the history of impacts on both the Earth and the Moon. According to the first comprehensive timeline of…
A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to…
Tracking the aerosols carried on the winds let scientists see the currents in our atmosphere. This visualization follows sea salt, dust, and smoke from July 31 to November 1, 2017, to reveal how these particles are transported across the map. The first thing that is…
Life. It's the one thing that, so far, makes Earth unique among the thousands of other planets we've discovered. Since the fall of 1997, NASA satellites have continuously and globally observed all plant life at the surface of the land and ocean. During the…
The International Meteor Organization (IMO) has just added a new feature to their online meteor shower calendar – a 3D animated view of the meteoroid streams the Earth will encounter all along its journey around the Sun. The model was created by Ian Webster, and…
This animation shows every recorded earthquake in sequence as they occurred from January 1, 2001, through December 31, 2015, at a rate of 30 days per second. This time period includes some remarkable events. Several large earthquakes caused devastating tsunamis,…
Our universe is more than a serene landscape of stars – it is teeming with activity from some extremely violent events. In a presentation at the IMAX theatre at the Smithsonian National Air and Space Museum in Washington, D.C. on September 30, scientists take us…
Our senses tell us about the natural world, but our senses cannot tell us everything. That’s why we use tools, and NASA develops some of the most sophisticated, most exciting tools of all. Designed to reveal aspects of the Earth, the Sun, The Moon, these tools…
