Astronomy Picture Of the Day (APOD)
APOD: 2026 April 26 Б Mystic Mountain Monster being Destroyed
25.04.2026
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.
APOD: 2026 April 25 Б The Persistence of Sunlight
24.04.2026
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.
APOD: 2026 April 24 Б Young Moon and Sister Stars
23.04.2026
Sunlit arms of a crescent moon seem to embrace the faint lunar night side in this dramatic celestial scene 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.
APOD: 2026 April 23 Б Large Scale Structure of the Universe
22.04.2026
This is a map of the universe. 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.
APOD: 2026 April 22 Б Earthset with an iPhone
21.04.2026
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. Commander Wiseman's video, taken with an iPhone at 8x zoom, shows our entire planet gradually blocked from view by the Moon.
APOD: 2026 April 21 Б Three Sky Arches over Snowy Alps
20.04.2026
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.
APOD: 2026 April 20 Б Comet R3 PanSTARRS over a Himalayan Valley
19.04.2026
The best way to see comet R3 PanSTARRSБs 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.
APOD: 2026 April 19 Б Eye on the Milky Way
18.04.2026
Have you ever had stars in your eyes? It appears that the eye on the left does, and moreover, it appears to be gazing at even more stars. The featured 27-frame mosaic was taken in 2019 from Ojas de Salar in the Atacama Desert of Chile.
APOD: 2026 April 18 Б PanSTARRS and Planets
17.04.2026
Near the eastern horizon before sunrise, Comet C/2025 R3 PanSTARRS is getting brighter. Readily visible in binoculars and small telescopes, the comet may be just on the verge of naked-eye visibility from dark sky sites.
APOD: 2026 April 17 Б M82: Starburst Galaxy with a Superwind
16.04.2026
Messier 82 is a starburst galaxy with a superwind. In fact, through supernova explosions and powerful winds from massive stars, the burst of star formation in M82 is driving a prodigious outflow. Evidence for the superwind from the galaxy's central regions is clear in the sharp telescopic portrait.
