#PPOD: With Mars on the opposite side of the Sun at dawn, only six planets were visible in this year's planetary parade, unlike last year, when all seven were in view. The timing of this shot was critical for the fainter planets, and @joshduryphotomedia.bsky.social cross-referenced... 🧪 🔭
Infrared photograph of an annular eclipse of the Sun with the shadow of the Moon almost entirely covering the star and leaving a yellow ring of the corona around the edges. Text: PROBA2/SWAP 17.4nm, 2026-02-17 11:31:53.
#PPOD: The Moon passed directly between the Sun and Earth on 17 February 2026, creating an annular solar eclipse. Because the Moon was at a more distant point along its elliptical orbit around Earth, it didn't entirely cover the Sun and left a ‘ring of fire’. 🧪 🔭
#PPOD: This beautiful image shows a swirling region of bright clouds in the wake of a cyclonic storm in Jupiter's atmosphere. On the left, you can see the turbulent, blue-tinted pole, while on the right, the polar clouds give way to the pinker belts and zones of Jupiter’s mid-latitudes. 🧪 🔭
Four panels of a cometary coma taken in infrared. Upper left: Red represents dust surrounding the coma in an elliptical shape. Upper right: Blue represents water in a sphere around the coma and scattered across the image. Bottom left: Green represents organics - carbon containing molecules - also in a sphere around the coma and more densely scattered in the image. Bottom right: Gold represents carbon dioxide in a sphere around the coma that takes up nearly the entire image.
#PPOD: These observations by NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) show the infrared light emitted by the dust, water, organic molecules, and carbon dioxide contained within comet 3I/ATLAS’s coma. 🧪 🔭
Orbiter image taken of the surface of Mars, showing several large Barchan dunes (nearly pointed arches) with the narrow ends to the right. The ground around the dunes is cracked and dry and seen in shades of tan and pale blue.
#PPOD: In this image, many sand dunes are visible. They have an elongated crescent form and are called "barchan dunes." They are formed by the continuous action of the wind, blowing in the same direction, giving this particular shape. 🧪 🔭

The image shows a portion of the fretted and cratered northwest margin of Tempe Terra, Mars. The scarp of the highland/lowland boundary is illuminated by the light of dawn and runs from near the lower left up in an arc to the upper right. Traces of fog appear in the lower portion. The area covered by the image is about 55 kilometers across.
#PPOD: This image of Mars was captured by the Dawn spacecraft near its closest approach during its February 17, 2009, gravity assist flyby. The photo wasn't taken for scientific purposes, as Mars is already being studied well by orbiters in place. 🧪 🔭
In the centre an opaque cloud of grey gas hides a star. Two strong beams of light from the star emerge from large holes in both sides of the cloud. The central cloud is surrounded by concentric, wispy shells of gas, illuminated by the star’s light. The shells reflect extra light where they’re hit by the twin beams. A crowd of smaller stars with cross-shaped spikes over them surround the nebula on a black background.
