NASA's Earth Observatory has posted its October 2026 Satellite Puzzler, an interactive quiz challenging readers to identify an unknown location shown in satellite imagery. The monthly feature invites people to study an aerial or orbital view and guess where on Earth it was taken, with the answer and explanation published afterwards. It is a recurring science outreach game aimed at geography and remote-sensing enthusiasts.
- 2NSF Solar Observatory Collaboration Wins NASA Award for 3D Eruption Model▼New 3D Solar Eruption Model: NSF National Solar Observatory Collaboration Wins NASA Award
A collaboration led by the NSF National Solar Observatory has received a NASA award for developing a new three-dimensional model of solar eruptions. The model is intended to improve understanding of how eruptions form and evolve, work that matters for space weather forecasting since solar eruptions can disrupt satellites, communications and power grids on Earth.

K2-111 c is a Neptune-like giant planet located 654 light-years from Earth, first identified in 2020 by multiple observatories. It has a mass about 11 times that of Earth and completes an orbit of its star in just 15.68 days. The planet's details are accessible through NASA's Eyes on Exoplanets tool.
- 4NASA Highlights Moon-Like Landscapes of Madagascar●Moon-Like Madagascar https://science.nasa.gov/earth/earth-observatory/moon-like-madagascar/ # EarthScience # Space # Ast
NASA's Earth Observatory is showcasing striking satellite imagery of Madagascar, highlighting landscapes so barren and eroded they resemble the surface of the Moon. The feature draws attention to the island's dramatic terrain, shaped by erosion and deforestation. Readers are sharing the images as a vivid example of how Earth can look as desolate as another world.

NASA's Earth Observatory has published a new map of the terrain beneath the Greenland Ice Sheet, showing hundreds of subglacial valleys that earlier maps missed or left fragmented. The updated picture of the bedrock landscape links these valleys into connected systems, improving understanding of how meltwater may drain and how the ice sheet could respond to warming.
- 6Nancy Grace Roman Telescope Doubles Mission Life on Less Fuel●Roman Telescope Saves Fuel, Doubles Mission https://hackaday.com/2026/09/30/roman-telescope-saves-fuel-doubles-mission/
The Nancy Grace Roman Space Telescope, NASA's upcoming wide-field infrared observatory, has reportedly extended its planned operational lifetime from five to ten years by adopting a fuel-efficient route to its observing point. Engineers achieved the doubling by conserving propellant during the journey to the Sun-Earth Lagrange point 2, giving astronomers far more observing time.
- 7Gas Giant HD 224538 b Profiled in NASA Exoplanet Data●Name: HD 224538 b A giant planet composed mainly of gas. Distance from Earth: 258 light-years Year discovered: 2016 Disc
The exoplanet HD 224538 b, a gas giant located 258 light-years from Earth, is drawing attention after a profile of its details circulated among space enthusiasts. Discovered in 2016 by multiple observatories, the planet has a mass of roughly 2,076 Earths and an orbital period of about 1,202 days. NASA's Eyes on Exoplanets visualization tool lets users explore the distant world directly.
- 8Powerful Storms Continue to Prowl the Pacific●Powerful Storms Continue to Prowl the Pacific https://science.nasa.gov/earth/earth-observatory/powerful-storms-continue-
NASA's Earth Observatory reports that powerful storms continue to move across the Pacific Ocean, documented through satellite imagery of the region. The imagery highlights the scale and persistence of the storm systems churning over Pacific waters. Beyond the headline, no further details are provided about specific locations affected, damage caused, or forecasts for the coming days.
