Webb Reveals Lion Nebula's Fate as Satellites Track El Niño and Extreme Tides
NASA's Webb telescope peers into the Lion Nebula's dusty heart, while satellites document El Niño's toll on Pacific life, extreme Australian tides, and Tanzania's unique lava.

New images from space are reshaping our view of both the cosmos and Earth's dynamic systems. NASA's James Webb Space Telescope, an international endeavor with ESA and CSA, has turned its NIRCam and MIRI instruments toward the planetary nebula NGC 2392, known as the Lion Nebula. Unlike the visible-light portrait captured by Hubble in 2000, Webb's infrared view reveals compact clumps of dust and a haze of ionized gas. The nebula's structure is powered by a white dwarf, the remnant of a dying star, which illuminates the interior of a dust shell that forms the lion's mane. The expanding gas bubble that outlines the lion's face is actively destroying dust in its path. Astronomers estimate that within roughly 10,000 years, the lion will have dispersed completely.
Closer to home, the El Niño that officially arrived in June 2026 is under intense satellite scrutiny. According to NOAA's Climate Prediction Center, the event is expected to strengthen through the end of the year, with a 97% chance of persisting into early Northern Hemisphere spring 2027. Data from the OCI instrument on the PACE satellite show that chlorophyll concentrations in the central Pacific near the equator, north of New Zealand, were substantially lower in June 2026 than in June 2025. El Niño weakens easterly trade winds, allowing the warm surface layer to deepen and suppressing the upwelling of cool, nutrient-rich water. This has already disrupted marine life: Peru's Ministry of Production repeatedly suspended the anchovy fishery in 2026, and pelicans have been spotted wandering into Peruvian ports and urban areas in search of food. The PACE mission, launched in February 2024, is experiencing its first complete El Niño, providing global, near-daily hyperspectral measurements. As Matthew Kehrli and Graham Trolley of NASA Goddard put it, "The scientific community will be able to observe the 2026 El Niño with data across more wavelengths of light than ever before."
Meanwhile, the Landsat 8 satellite captured an image of Roebuck Bay in Western Australia on March 18, 2026, using its OLI instrument. The bay is renowned for extreme tides that can reach 9 meters (30 feet). Decades of Landsat observations reveal that its mangrove forests are expanding westward by nearly 2 meters per year. The mudflats are teeming with life, hosting shells and snails at densities up to 2,500 per square meter, according to the Australian government. Roebuck Bay is also one of the most important sites for migratory birds in Australia, serving as a key stop on the East Asian-Australasian Flyway.
Across the globe, Tanzania's Ol Doinyo Lengai volcano offers a different kind of spectacle. Known to the Maasai as the "Mountain of God," this stratovolcano rises up to 9,718 feet (2,692 meters) above the Arusha plains. It has been erupting intermittently for the past 15,000 years, with the current effusive phase ongoing since April 2017, according to the Smithsonian Global Volcanism Program. Its lava is natrocarbonatite, rich in sodium, potassium, and calcium carbonate but low in silica, allowing it to cool below 1,100°F (600°C) and flow with unusually low viscosity, making it some of the fastest-moving lava on Earth. The youngest of the pale flows dates from the 1998 eruption, and explosive activity between 2007 and 2008 created a 330-foot-tall (100 m) ash cone at the summit. An astronaut photo from the ISS, taken on October 6, 2020, captures the volcano, which sits in the East African Rift System, about 10 miles (16 km) south of Lake Natron, where the African Plate is splitting into the Somali and Nubian plates.
