Astronomy Picture Of the Day (APOD)
APOD: 2026 March 8 Á The Aurora Tree
7.03.2026
Yes, but can your tree do this? Pictured is a visual coincidence between the dark branches of a nearby tree and bright glow of a distant aurora. The beauty of the aurora -- combined with...
APOD: 2026 March 7 Á Two Eclipses of Saros 133
6.03.2026
Centered on maximum eclipse, these two total lunar eclipse sequences look almost identical. Yet the one shown on top is composed of images recorded in February 2008, while at the bottom is the recent March 2026 total eclipse of the Moon. Why are they so similar?
APOD: 2026 March 6 Á The Astrosphere of HD 61005
5.03.2026
Do young stars blow bubbles? The larger view shows a stellar field observed with the Cerro Tololo Inter-American Observatory in Chile, and the inset highlights HD 61005, a star like our Sun, only 120 light-years away.
APOD: 2026 March 5 Á Total Lunar Eclipse over Tse Bitai
4.03.2026
Earlier this week, EarthÁs shadow swept across the full Moon in the yearÁs only total lunar eclipse. This stunning sequence combines images showing the MoonÁs path across the night sky. Each lunar image captures our planetÁs shadow gradually engulfing the Moon, culminating in its red glow.
APOD: 2026 March 4 Á Shapley 1: An Annular Planetary Nebula
3.03.2026
WhatÁs looking back at you isnÁt a cosmic eye, but Shapley 1, a beautifully symmetric planetary nebula. Shapley 1, also known as the Fine Ring Nebula or PLN 329+2.1, bejewels the southern sky constellation of the Carpenter's Square (Norma).
APOD: 2026 March 2 Á The Dusty Surroundings of Orion and the Pleiades
1.03.2026
How well do you know the night sky? OK, but how well can you identify famous sky objects in a very deep image? Either way, here is a test: see if you can find some well-known night-sky icons in a deep image filled with filaments of normally faint dust and gas.
Lunar Occultation of Mercury
27.02.2026
Fans of the western sky after sunset have lately enjoyed this month's remarkable array of bright planets. Witnessed from some locations, on February 18 planet Mercury even appeared to slide behind the Moon, an event known as a lunar occultation.
Sharpless 249 and the Jellyfish Nebula
26.02.2026
Normally faint and elusive, the Jellyfish Nebula is caught in this alluring telescopic field of view. Floating in the interstellar sea, the nebula is anchored right and left by two bright stars, Mu and Eta Geminorum, at the foot of the celestial twins.
Webb and Hubble: IC 5332
25.02.2026
What does the universe look like through infrared goggles? Our eyes can only see visible light, but astronomers want to see more. TodayÁs APOD shows spiral galaxy IC 5332 as seen by two NASA telescopes: Webb in mid-infrared and Hubble in ultraviolet and visible light.
APOD: 2026 February 25 Á The Egg Nebula from the Hubble Telescope
24.02.2026
Ever wonder what it would look like to crack open the Sun? The Egg Nebula, a dying Sun-like star, can unscramble this question. Pictured is a combination of several visible and infrared images of the nebula (also known as RAFGL 2688 or CRL 2688) taken with the Hubble Space Telescope.
