2026-04-20 | Comet R3 PanSTARRS over a Himalayan Valley | The best way to see comet R3 PanSTARRS’s long tail is with a camera. This week, the recently brightened comet appears in northern skies to the east just before dawn, but is only barely visible to the unaided eye. The many-degree ion tail captured on long duration camera exposures is not unusual for a comet - it is prim... | image | Basudeb Chakrabarti &

2026-04-21 | Three Sky Arches over Snowy Alps | Why are there three arches across the sky instead of two? Last month, after being dropped off by a helicopter at a high mountain peak in the Alps near the Swiss Italian border, an adventurous astrophotographer expected two arches of our Milky Way galaxy to be visible during the night. These were the inner arch looking ... | image | Angel Fux | null | false | 2,026 | 4 | ||
2026-04-22 | Earthset with an iPhone | What does it mean for the Earth to set? Artemis II Commander Reid Wiseman gave us another spectacular view of Earth from their historic flyby of the Moon.

On the Earth, the 24-hour planetary rota... | https://youtube.com/embed/MT8tg5b3b8E?si=46r2TF9THNvtq1ep | null | video | null | true | 2,026 | 4 | |

The Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory, Arizona, has finished its five-year survey. It observed more than 47 million galaxies and quasars and created a 3D map centered on the Earth. Today's featured image shows a thin slice of these data: the bla... | image | null | null | true | 2,026 | 4 | ||
2026-04-24 | Young Moon and Sister Stars | Sunlit arms of a crescent moon seem to embrace the faint lunar night side in this dramatic celestial view from planet Earth. The single telephoto exposure tracking the sky was captured on the night of April 19, when a two day old Moon was near perigee in its elliptical orbit. On that date, the young Moon was also close... | image | Giorgia Hofer | null | false | 2,026 | 4 | ||
2026-04-25 | The Persistence of Sunlight | This seaside sunset offered a surreal experience, captured in a sea and skyscape from the west coast of Sardinia, Italy, planet Earth. The Daliesque scene is a composition of sequential exposures made with a camera and long telephoto lens. The Sun is not melting, though. Its shifting and fluid appearance as it nears th... | image | Lorenzo Busilacchi | null | false | 2,026 | 4 | ||
2026-04-26 | Mystic Mountain Monster being Destroyed | Inside the head of this interstellar monster is a star that is slowly destroying it. The huge monster, actually an inanimate series of pillars of gas and dust, measures light years in length. The in-head star is not itself visible through the opaque interstellar dust but is bursting out partly by ejecting opposing be... | image | null | null | true | 2,026 | 4 |
