NASA’s Oct. 31, 2026 Astronomy Picture of the Day features a Halloween-themed night photograph from Hverir, Iceland, where auroras appear above steaming geothermal vents. NASA attributes the auroras to energetic particles entering Earth’s upper atmosphere during geomagnetic storms and says auroral activity remains high as the Sun begins declining from its activity-cycle peak.
NASA’s Astronomy Picture of the Day for October 31, 2026, shows northern lights above steaming geothermal vents at Hverir in northeastern Iceland, presenting the scene as a Halloween-night view of Earth. The agency says geomagnetic storms, triggered by solar activity, send energetic particles into the upper atmosphere to produce auroras, and reports that auroral activity remains high as the Sun begins declining from its activity-cycle peak.
The photograph, credited to Stéphane Vetter of Nuits sacrées, captures a starry sky tinted green by auroral light, with towers of steam and gas rising from local fumaroles. NASA’s accompanying explanation identifies the location as Hverir, a geothermally active area in Iceland’s volcanic landscape. The visual juxtaposes two different sources of activity: geothermal emissions at the ground and solar-driven light in the sky, much like the auroral scene in another October APOD.
NASA explains that energetic particles trapped in Earth’s magnetic field penetrate the upper atmosphere at high latitudes during geomagnetic storms, creating auroral displays, a topic also explored in an APOD about simulated dark matter. The agency says the current period of elevated auroral activity reflects the Sun’s position in its activity cycle: it is in the early stages of decline from the cycle’s peak. The APOD text does not give a specific storm measurement or forecast for particular locations.
The daily feature is part of NASA’s Astronomy Picture of the Day service, which pairs an image or photograph with an explanation written by a professional astronomer, as in this Andromeda entry. The October 31 entry was edited by Jerry Bonnell, Cecilia Chirenti, Robert Nemiroff and Keighley Rockcliffe, and credits the service to NASA’s Astrophysics Science Division at Goddard Space Flight Center, NASA Science Activation and Michigan Technological University.
Auroras Beyond the Iceland Scene
The image offers a timely illustration of how solar activity can produce visible effects on Earth. Auroras are not limited to a photograph or a particular Icelandic landscape: they occur when charged particles interact with gases high in the atmosphere, and their visibility depends on conditions including geomagnetic activity and location. NASA’s note that activity remains high makes the image relevant to people interested in whether auroras may be visible beyond their usual viewing areas.
That possibility should not be read as a forecast that lights will appear in any specific neighborhood. The APOD description says other auroral displays may appear locally, but provides no dates, geographic range, probability, or observing guidance. The photograph’s immediate value is therefore both explanatory and illustrative: it connects a striking view to the solar and atmospheric processes behind it while leaving local viewing prospects open.
The setting also makes the image a compact lesson in Earth’s varied natural systems. Steam from Iceland’s geothermal vents is visible in the same frame as light produced high above the planet. NASA’s caption distinguishes those processes rather than suggesting the vents cause the aurora. The Halloween framing is a presentation choice; the reported explanation is grounded in familiar geophysical and space-weather phenomena.

How NASA Frames the Halloween Image
NASA’s APOD entry begins with a playful question about the identity of the “spooky planet,” then answers that it is Earth on a dark and stormy night. The date and seasonal framing account for the ghostly description, while the location and caption identify the scene as a real photograph from Hverir. The reference to steam “dancing” against the lights describes the appearance, not a separate scientific claim.
In the explanation, NASA links the aurora to geomagnetic storms associated with solar activity and describes the Sun as being in an early decline from the peak of its activity cycle. The source does not specify the cycle’s numerical phase, the date of its peak, or the strength of a particular storm. It also does not say that the image was taken during a newly announced event; the development is the publication of the daily astronomy feature and its account of the scene.
The APOD service presents a new image or photograph each day with a short expert-written explanation. Its October 31, 2026 entry lists “many moons” as the subject of the following day’s picture. That listing signals the next scheduled feature, not a new finding about the aurora or a change in NASA’s space-weather outlook.
Local Aurora Viewing Remains Unspecified
The APOD entry does not provide a location-specific aurora forecast, so it cannot establish whether lights will be visible in any particular neighborhood or on a particular night. It gives no forecast window, storm index, visibility probability or geographic boundary for the suggestion that auroras may appear elsewhere.
The source also does not state when the photograph was taken, beyond identifying its location and publishing it on October 31, 2026. It supplies no technical measurements of the geomagnetic storm or the particles involved, and does not specify the Sun’s activity-cycle phase with a date or numerical indicator. Those details should not be inferred from the image or its seasonal theme.
The Next Daily Astronomy Picture
NASA’s APOD listing names “many moons” as the subject of the picture scheduled for November 1, 2026. That is the next item indicated by the source; the October 31 entry does not announce a further aurora report or a specific observing update.
Readers seeking information about possible local auroras would need a current, location-specific space-weather forecast, since the APOD caption does not provide one. NASA’s daily feature is expected to continue with its next image and explanation, while the timing and visibility of any additional auroral displays remain unspecified here.
Key Questions
What does NASA’s October 31, 2026 APOD show?
It shows auroral light above steaming geothermal vents at Hverir in northeastern Iceland. The photograph is credited to Stéphane Vetter of Nuits sacrées.
What causes the northern lights in the image?
NASA says geomagnetic storms associated with solar activity send energetic particles into Earth’s upper atmosphere at high latitudes, producing auroral displays.
Does NASA say the aurora will be visible everywhere?
No. The APOD says auroral activity remains high and suggests displays may appear in other areas, but gives no specific forecast, timing or location.
Are the steam and aurora caused by the same process?
No. NASA describes the steam and gas as emissions from geothermal fumaroles at Hverir, while it attributes the aurora to energetic particles interacting with the upper atmosphere.
What is the next APOD subject listed?
The listing names “many moons” for November 1, 2026. The October 31 entry does not give further details about that upcoming image.
