Astronomy Picture Of the Day (APOD)
APOD: 2024 May 28 Б Solar X Flare as Famous Active Region Returns
27.05.2024
It's back. The famous active region on the Sun that created auroras visible around the Earth earlier this month has survived its rotation around the far side of the Sun -- and returned. Yesterday...
Chamaeleon I Molecular Cloud
26.05.2024
Dark markings and bright nebulae in this telescopic southern sky view are telltale signs of young stars and active star formation. They lie a mere 650 light-years away, at the boundary of the local bubble and the Chamaeleon molecular cloud complex.
APOD: 2024 May 26 Б A Solar Filament Erupts
25.05.2024
What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space, producing an energetic coronal mass ejection (CME).
Manicouagan Impact Crater from Space
24.05.2024
Orbiting 400 kilometers above Quebec, Canada, planet Earth, the International Space Station Expedition 59 crew captured this snapshot of the broad St. Lawrence River and curiously circular Lake Manicouagan on April 11. Right of center, the ring-shaped lake is a modern reservoir within the eroded remnant of an ancient 100 kilometer diameter impact crater.
APOD: 2024 May 24 Б M78 from the Euclid Space Telescope
23.05.2024
Star formation can be messy. To help find out just how messy, ESA's new Sun-orbiting Euclid telescope recently captured the most detailed image ever of the bright star forming region M78. Near...
Unraveling NGC 3169
22.05.2024
Spiral galaxy NGC 3169 looks to be unraveling like a ball of cosmic yarn. It lies some 70 million light-years away, south of bright star Regulus toward the faint constellation Sextans. Wound up spiral arms are pulled out into sweeping tidal tails as NGC 3169 (left) and neighboring NGC 3166 interact gravitationally.
APOD: 2024 May 22 Б Green Aurora over Sweden
21.05.2024
It was bright and green and stretched across the sky. This striking aurora display was captured in 2016 just outside of цstersund, Sweden. Six photographic fields were merged to create the featured panorama spanning almost 180 degrees. Particularly striking aspects of this aurora include its sweeping arc-like shape and its stark definition.
APOD: 2024 May 21 Б CG4: The Globule and the Galaxy
20.05.2024
Can a gas cloud eat a galaxy? It's not even close. The "claw" of this odd looking "creature" in the featured photo is a gas cloud known as a cometary globule. This globule, however, has ruptured. Cometary globules are typically characterized by dusty heads and elongated tails.
APOD: 2024 May 20 Б Aurora Dome Sky
19.05.2024
It seemed like night, but part of the sky glowed purple. It was the now famous night of May 10, 2024, when people over much of the world reported beautiful aurora-filled skies. The featured image was captured this night during early morning hours from Arlington, Wisconsin, USA.
APOD: 2024 May 19 Б Jupiter Diving
18.05.2024
Take this simulated plunge and dive into the upper atmosphere of Jupiter, the Solar System's ruling gas giant. The awesome animation is based on image data from JunoCam, and the microwave radiometer on board the Jupiter-orbiting Juno spacecraft.
