Astronomy Picture Of the Day (APOD)
The Protostars within Lynds 483
13.03.2025
Two protostars are hidden in a single pixel near the center of a striking hourglass-shaped nebula in this near-infrared image from the James Webb Space Telescope. The actively forming star system lies in a dusty molecular cloud cataloged as Lynds 483, some 650 light-years distant toward the constellation Serpens Cauda.
APOD: 2025 March 12 Б NGC 772: The Fiddlehead Galaxy
12.03.2025
Why does this galaxy look like a curly vegetable? The Fiddlehead spiral galaxy likely gets its distorted spiral appearance from a gravitational interaction with its close-by elliptical companion NGC 770, seen just below. Cataloged...
APOD: 2025 March 11 Б NGC 1672: Barred Spiral Galaxy from Hubble
11.03.2025
Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a modest central bar. Prominently barred spiral galaxy NGC 1672, featured here, was captured in spectacular detail in an image taken by the orbiting Hubble Space Telescope.
APOD: 2025 March 10 Б NGC 1499: The California Nebula
10.03.2025
Could Queen Calafia's mythical island exist in space? Perhaps not, but by chance the outline of this molecular space cloud echoes the outline of the state of California, USA. Our Sun has its home within the Milky Way's Orion Arm, only about 1,000 light-years from the California Nebula.
APOD: 2025 March 9 Б Cyclones at Jupiters North Pole
9.03.2025
Why are there so many cyclones around the north pole of Jupiter? The topic is still being researched. NASA's robotic Juno mission orbiting Jupiter took data in 2018 that was used to construct this stunning view of the curious cyclones at Jupiter's north pole.
Galaxies in Space
8.03.2025
The plane of our Milky Way galaxy extends beyond the limb of planet Earth in this space age exposure captured by astronaut Don Pettit. His camera, with low light and long duration settings, was pointed out the window of a Dragon crew spacecraft docked with the International Space Station on January 29.
Planetary Nebula Abell 7
7.03.2025
Very faint planetary nebula Abell 7 is about 1,800 light-years distant. It lies just south of Orion in planet Earth's skies toward the constellation Lepus, The Hare. Surrounded by Milky Way stars...
Starburst Galaxy Messier 94
6.03.2025
Beautiful island universe Messier 94 lies a mere 15 million light-years distant in the northern constellation of the hunting dogs, Canes Venatici. A popular target for earth-based astronomers, the face-on spiral galaxy is about 30,000 light-years across, with spiral arms sweeping through the outskirts of its broad disk.
APOD: 2025 March 5 Б Seven Sisters versus California
5.03.2025
On the right, dressed in blue, is the Pleiades. Also known as the Seven Sisters and M45, the Pleiades is one of the brightest and most easily visible open clusters on the sky. The Pleiades contains over 3,000 stars, is about 400 light years away, and only 13 light years across.
APOD: 2025 March 4 Б A Quadruple Alignment over Italy
4.03.2025
Why does this Moon look so unusual? A key reason is its vivid red color. The color is caused by the deflection of blue light by Earth's atmosphere -- the same reason that the daytime sky appears blue. The Moon also appears unusually distorted.
