A dense knot of dust an gas in the Milky Way known as a Bok globule. These clouds contain elements essential for star formation.

1er jour de la semaine, 1ère image-mystère.

Que voit-on ici à votre avis ?
Laissez vos propositions en commentaire, je posterai la réponse en fin de journée.

(et laissez Google Images de côté, c'est nettement moins rigolo sinon 😉)

A flat landscape is shown at night that appears mostly brown. Numerous unusual rock spires are seen rising from the group. Above, a full star field is seen with the arch of our Milky Way Galaxy curving from left to right. Please see the explanation for more detailed information.

Bullet cluster - JWST.
Processed by c.claude.

🔭 🧪
This Near-Infrared Camera (NIRCam) image shows the Bullet Cluster, a powerful astronomical event resulting from the collision of two galaxy clusters. The image features a bright, central core with a distinct pinkish hue, representing the hot gas. Surrounding this core are countless individual galaxies, seen as bright white and yellowish dots, scattered across the dark background of space. Extending outwards from the center are faint, blue streaks, indicative of the superheated gas that was pulled away during the collision. The overall scene conveys a sense of immense energy and cosmic dynamism.

Asteroid 2024 YR4 may hit Earth in 2032 - how worried should we be?
The risk of asteroid 2024 YR4 hitting Earth seems to be creeping up as astronomers gather more data, but does that mean we should be scrambling to prepare for an impact in 2032?

Astronomie: Ein Nebel, der von sich aus leuchtet
Im Sternbild Zwillinge ist der planetarische Nebel NGC 2392 zu finden, ein Schmuckstück des Winterhimmels. Entdeckt wurde diese schöne Hülle eines sterbenden Sterns im Jahr 1787. Von Heike Westram.

IR image of the iconic Horsehead nebula by Hubble.
🔭 🧪
This is an infrared image of the Horsehead Nebula taken by the Hubble Space Telescope. The image shows a dark, horse-head-shaped cloud of dust and gas, known as Barnard 33, rising from a turbulent background of glowing gas and bright stars. The "neck" of the horse faces to the lower left. The image is dominated by hues of red and brown from the dust, with areas of blueish light outlining the edges of the nebula where it is being illuminated by surrounding stars. Numerous stars are scattered throughout the image, appearing as bright white points of light. The overall scene has a dramatic and majestic feel.

Andromeda, our cosmic neighbour. If it were more visible, it would appear 6 times bigger than the full moon. Imagine the night sky with such an amazing view.

Boston MA (SPX) Feb 03, 2025 - Highly energetic explosions in the sky are commonly attributed to gamma-ray bursts. We now understand that these bursts originate from either the merger of two neutron stars or the collapse of a mas

A not particularly clear picture of a crescent moon with a bright dot of Venus to the upper right. The sky behind is a deepening blue.

Ever heard of a "Dead Galaxy"?

NGC 1052-DF2 is such a galaxy, it has been proposed that it has little to no dark matter and minimal star formation. This makes it unique among galaxies. Its ghostly appearance also adds to its mysterious nature.

I decided to see the Seestar S50 & Askar80PHQ on the same target (NGC2174 - Monkey Head Nebula) to get a comparison - (editing aside) interesting what the Seestar can do!

Diamond Dust Sky Eye

#Space #Astronomy #Cosmos #Universe #Galaxy #SpaceExploration
Why is there a huge eye in the sky? Diamond dust. That is an informal term for small ice crystals that form in the air and flitter to the ground. Because these crystals are geometrically shaped, they can together reflect light from the Sun or Moon to your eyes in a systematic way, causing huge halos and unusual arcs to appear. And sometimes, together the result can seem like a giant eye looking right back at you. In the featured image taken in the Ore Mountains of the Czech Republic last week, a bright Moon rising through ice fog-filled air resulted in many of these magnificent sky illusions to be visible simultaneously. Besides Moon dogs, tangent arcs, halos, and a parselenic circle, light pillars above distant lights are visible on the far left, while Jupiter and Mars can be found just inside the bottom of the 22-degree halo.

Aurora Georgia

A familiar sight from Georgia, USA, the Moon sets near the western horizon in this rural night skyscape. Captured on May 10 before local midnight, the image overexposes the Moon's bright waxing crescent at left in the frame. A long irrigation rig stretches across farmland about 15 miles north of the city of Bainbridge. Shimmering curtains of aurora shine across the starry sky, definitely an unfamiliar sight for southern Georgia nights. Last weekend, extreme geomagnetic storms triggered by the recent intense activity from solar active region AR 3664 brought epic displays of aurora, usually seen closer to the poles, to southern Georgia and even lower latitudes on planet Earth. As solar activity ramps up, more storms are possible. AuroraSaurus: Report your aurora observations
