Why do the white blob and the yellow blob appear to be windblown in opposite directions? The windblown white blob, by the way, is ever so slightly similar to Hubble's Variable Nebula . https://upload.wikimedia.org/wikipedia/commons/thumb/8/8b/Hubble%27s_Variable_Nebula_-_NGC_2261.png/290px-Hubble%2...

disk shadow 1 The disk around the intermediate-mass young star EC 82 casts a large shadow on surrounding reflection nebulosity, giving rise to the so-called “Great Serpens Disk Shadow” sh1.jpgsh1+.jpg https://asterisk.apod.com/download/file.php?id=49932&mode=view That's an impressive disk shado...

In Thule Greenland where I worked for a year the summer solstice full moon remains about 14.5 degrees below the horizon. When the Sun is high in the sky, in the summer, the Moon is low in the sky. Of course, the Sun is never high in the sky in (northern) Greenland, but during the summer solstice th...

Marvellous image, cosmic creation in full force! And we barely need to "surmise" what's going on, we see those new worlds forming! (even more so in AVAO's zoom-in link) Here is some context about the environment and the comparison between Optical and IR. Dynamic area up there ,-) https://...

HST: NGC 3059 - A broad and narrow galactic view NASA/ESA | Original release 2024 June 3 https://cdn.esahubble.org/archives/images/screen/potw2423a.jpg A spiral galaxy seen face-on, so that its many arms and its glowing, bar-shaped core can be easily seen. The arms are filled with bluish patches of...

How large is a piece of the dust. Is it hot? If not, then there is no chance of it to conglomerate and form a star. Dust (and gas) needs to be cold - really very cold - in order to for gravity to make it sink into its own gravity well and become concentrated enough to eventually form a star. If the...

Note how the Doodad is leaking smoke along its entire length! https://apod.nasa.gov/apod/image/2406/Doodad_PughSung_1080.jpg Note in particular the dusty gusts of smoke that seem to surround globular cluster NGC 4372. Note the small blue foreground star on the right "corner" of NGC 4372 th...

Telescopes as time machines is a familiar idea but we should never lose sight of how extraordinary this is! Imagine if palaeontologists could study actual pictures of dinosaurs! Or if historians could see pictures of Cleopatra, or geologists seeing pictures of the Late Heavy Bombardment! What’s mor...

How is it that when looking north, east is to your left? Not on any compass I've ever seen. Is this photo a mirror-reversed image? If you lay on the ground, with your head to the north, east is to your left. Stellar coordinates mirror terrestrial coordinates because instead of being drawn on the ou...

Unsurprisingly, I remember this picture from 2005 very well! :D https://www.esa.int/var/esa/storage/images/esa_multimedia/images/2014/06/saturn_s_shadows/14598392-1-eng-GB/Saturn_s_shadows_card_medium.jpg https://apod.nasa.gov/apod/image/2406/SaturnColors_CassiniSchmidt_960.jpg So why is the norther...

Telltale yet hidden seems contradictory! Where in the image do we see signs of HH objects?

Maybe these:

Well, dark nebulas are not my forte and not my interest, but... let's have some fun, shall we? I see a a very tall cosmic mermaid-alien with bad hair, a misshapen hand and a fishtail in this dark nebula. What do you see?

It has been said of the brilliant Indian mathematician Ramanujan that every natural number, for instance 1729, was a friend of his (If you have not heard of him, look him up in Wikipedia ). Likewise, it seems to me that every galaxy in the Messier and NGC catalogues is a friend of Ann. :wink: Thank...

Today's APOD is a nice image, and I'm very glad indeed that Hubble is back in action! https://apod.nasa.gov/apod/image/2406/NGC1546compassHST1024.jpg NGC 1546 reminds me somewhat of M63 because of its inclination and its small scattered clusters and thick dust lanes: https://science.nasa.gov/wp-cont...

Me being me, I'll leave the discussion of the APOD to the rest of you, while I go Oohh! and Aahh! 🥳 over the magnificent O-type stars 🌟🌟🌟🌟 of Cluster NGC 6193, the ionizing stars of the Dragons of Ara. 🐉 Wikipedia wrote about HD 150136 and cluster NGC 6193: All three (four, including HD 150135) of t...

The image is striking (pun intended). The number of Jets is a good question. It appears that there are 5 with 2 converging and one (on the right) diverging. But, I am wondering what is the bright object in the middle of the frame? to answer that we need to recognize the star field. Is there a star ...

The same mysterious nebula was depicted ten years ago (https://apod.nasa.gov/apod/ap140718.html). But then, the "telltale blue emission from doubly ionized oxygen" was not blue but very clearly green! So, which is the correct colour aand why? The blue color is not true. What we see is OII...

I want to believe that the central star of Ou4, the multiple star HR 8119, of spectral class O9.5IV, or B0V, or B0IV, had an outburst and created Ou4, an...

We can't see any major star formation in NGC 3628 (if it has any) because of its edge-on perspective, but it appears that M66 is the Leo Triplet member that has the highest rate of star formation. (M65 appears to have almost none.) An interesting ESO image shows the cold gas in M66, which provides ...
