Astronomy Picture Of the Day (APOD)
Apollo 17: The Crescent Earth
12.05.2023
Our fair planet sports a curved, sunlit crescent against the black backdrop of space in this stunning photograph. From the unfamiliar perspective, the Earth is small and, like a telescopic image of a distant planet, the entire horizon is completely within the field of view.
Halley Dust, Mars Dust, and Milky Way
11.05.2023
Grains of cosmic dust streaked through night skies in early May. Swept up as planet Earth plowed through the debris streams left behind by periodic Comet Halley, the annual meteor shower is known as the Eta Aquarids. This year, the Eta Aquarids peak was visually hampered by May's bright Full Moon, though.
Fomalhaut's Dusty Debris Disk
10.05.2023
Fomalhaut is a bright star, a 25 light-year voyage from planet Earth in the direction of the constellation Piscis Austrinus. Astronomers first noticed Fomalhaut's excess infrared emission in the 1980s. Space and ground-based...
APOD: 2023 May 10 B Milky Way over Egyptian Desert
9.05.2023
For ten years the stargazer dreamed of taking a picture like this. The dreamer knew that the White Desert National Park in Egypt's Western Desert is a picturesque place hosting numerous chalk formations sculpted into surreal structures by a sandy wind.
APOD: 2023 May 9 B Shadows of Earth
8.05.2023
Can you find two Earth shadows in today's image? It's a bit tricky. To find the first shadow, observe that the top part of the atmosphere appears pink and the lower part appears blue. This is because the top half is exposed to direct sunlight, while the lower part is not.
APOD: 2023 May 8 B The Spanish Dancer Spiral Galaxy
7.05.2023
If not perfect, then this spiral galaxy is at least one of the most photogenic. An island universe containing billions of stars and situated about 40 million light-years away toward the constellation of the Dolphinfish (Dorado), NGC 1566 presents a gorgeous face-on view.
APOD: 2023 May 7 B The Helix Nebula from CFHT
6.05.2023
Will our Sun look like this one day? The Helix Nebula is one of brightest and closest examples of a planetary nebula, a gas cloud created at the end of the life of a Sun-like star.
Twilight in a Flower
5.05.2023
Transformed into the petals of a flower, 16 exposures show the passage of day into night in this creative timelapse skyscape. Start at the top and move counterclockwise to follow consecutive moments as the twilight sky turns an ever darker blue and night blossoms.
Shackleton from ShadowCam
4.05.2023
Shackleton crater lies at the lunar south pole. Peaks along the 21 kilometer diameter are in sunlight, but Shackleton's floor is in dark permanent shadow. Still, this image of the shadowed rim wall...
The Galaxy, the Jet, and a Famous Black Hole
3.05.2023
Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured in 2017 by planet Earth's Event Horizon Telescope in the first ever image of a black hole. Giant...
