Tropical Cyclone Narelle Crosses Australia
Tropical Cyclone Narelle traced a long path across the northern edge of Australia, bringing damaging winds and rain to areas already saturated with abundant precipitation. The system made separate landfalls in three different states and territories between March 20 and 23, 2026. These satellite images show Narelle at about 2 p.m. local time (04:00 Universal Time) on March 19. By…

See NASA’s GUARDIAN Catch a Tsunami
A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the software detects slight distortions in satellite navigation signals to spot hazards on the move.. The animation breaks down a real-life case study: last summer’s massive Kamchatka earthquake…

Science Through Shadows: How Astronomical Alignments Reveal the Universe
When one celestial object passes in front of another, it can cast a shadow that travels across space – and sometimes across Earth. These moments of alignment, known as eclipses, occultations, and transits, allow scientists to study distant objects in remarkable ways. By observing how light changes when an object briefly blocks another, astronomers can measure sizes and shapes, detect…

SWOT Mission Unlocks a New View of Our Waterways
Explore how rivers move, change, and sustain life across the planet. Using data from the SWOT (Surface Water and Ocean Topography) mission, jointly developed by the NASA/JPL and the Centre National d’Études Spatiales with contributions from the Canadian Space Agency and the United Kingdom Space Agency, scientists can now measure rivers continuously and across the entire globe for the first…

NASA’s Hubble, Webb Telescopes Survey Pinwheel Galaxy
This March 16, 2026, image from NASA’s Hubble Space Telescope and the James Webb Space Telescope takes a closer look at the core of Messier 101, also known as the Pinwheel Galaxy. At 25 million light-years away, M101 is one of the closest “face-on” spiral galaxies to us. With that in mind, Hubble’s ultraviolet, visible, and near-infrared data were taken…

NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion
A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over Hubble’s long lifetime. A paper detailing the new Hubble observation is published in The Astrophysical Journal. This new Hubble observation…

A Fault Line in Full Bloom
Whether it qualifies as a “superbloom” is in the eye of the beholder, but there is no doubt that California’s Carrizo Plain and the neighboring mountain ranges were awash with color as wildflowers put on their annual show in spring 2026. Landsat satellites began to show the early signs of color in February. By early March, flowers had turned areas around Soda Lake a…
