NGC 7293: The Helix Nebula
10.05.2003

Will our Sun look like this one day? The Helix Nebula is the closest example of a planetary nebula created at the end of the life of a Sun-like star. The outer gasses of the star expelled into space appear from our vantage point as if we are looking down a helix.

APOD: 2026 April 7 Б IC 4592: The Blue Horsehead Reflection Nebula
7.04.2026

Do you see the horse's head? What you are seeing is not the famous Horsehead nebula toward Orion, but rather a fainter nebula that only takes on a familiar form with deeper imaging. The main part of the here-imaged molecular cloud complex is reflection nebula IC 4592.

APOD: 2026 January 11 Б M104: The Sombrero Galaxy in Infrared
11.01.2026

This floating ring is the size of a galaxy. In fact, it is a galaxy -- or at least part of one: the photogenic Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies.

APOD: 2024 October 22 Б M16: Pillars of Star Creation
22.10.2024

These dark pillars may look destructive, but they are creating stars. This pillar-capturing picture of the Eagle Nebula combines visible light exposures taken with the Hubble Space Telescope with infrared images taken with the James Webb Space Telescope to highlight evaporating gaseous globules (EGGs) emerging from pillars of molecular hydrogen gas and dust.

APOD: 2025 May 25 Б Beneath Jupiter
25.05.2025

Jupiter is stranger than we knew. NASA's Juno spacecraft has now completed over 70 swoops past Jupiter as it moves around its highly elliptical orbit. Pictured from 2017, Jupiter is seen from below where, surprisingly, the horizontal bands that cover most of the planet disappear into swirls and complex patterns.

APOD: 2025 May 9 Б IXPE Explores a Black Hole Jet
9.05.2025

How do black holes create X-rays? Answering this long-standing question was significantly advanced recently with data taken by NASAБs IXPE satellite. X-rays cannot exit a black hole, but they can be created in the energetic environment nearby, in particular by a jet of particles moving outward.

APOD: 2025 April 23 Б An Almost Everything Sky
23.04.2025

This surprising sky has almost everything. First, slanting down from the upper left and far in the distance is the central band of our Milky Way Galaxy. More modestly, slanting down from the upper right and high in Earth's atmosphere is a bright meteor.

APOD: 2025 May 20 Б Milky Way over Maunakea
20.05.2025

Have you ever seen the band of our Milky Way Galaxy? In a clear sky from a dark location at the right time, a faint band of light becomes visible across the sky. Soon after your eyes become dark adapted, you might spot the band for the first time. It may then become obvious.

APOD: 2026 February 2 Б Orion: The Running Man Nebula
2.02.2026

What part of Orion is this? Just north of the famous Orion Nebula is a picturesque star forming region in Orion's Sword that contains a lot of intricate dust -- some of which appears blue because it reflects the light of bright embedded stars.

APOD: 2025 May 13 Б Gaia Reconstructs a Top View of our Galaxy
13.05.2025

What does our Milky Way Galaxy look like from the top? Because we are on the inside, humanity canБt get an actual picture. Recently, however, just such a map has been made using location data for over a billion stars from ESAБs Gaia mission.
