Starship Asterisk*

...interesting to compare with IR...

Those stars are, however, inside a thick dust nebula; they may all be already born, may already have broken their tight dust cocons. So the star of the perinatal story is a first Ok I agree. That's right. https://live.staticflickr.com/65535/52341871933_f6ba9830de_c.jpg jac berne (flickr) JWST overl...

...It seems certain, at least to me, that the red "arclet" of the M51 system (which is thousands of light-years long, of course) is a shock front of some sort. The glowing Veil Nebula is a typical shock front. We know what kind of shock created the Veil Nebula, of course. It was a superno...

I don't suppose anyone is planning to launch a satellite into a "junostationary" orbit (like Himawari-8 is to Earth, producing the images above). Or one at a Lagrange point for Jupiter (like DSCOVR for Earth), which is another convenient place to capture this. I like this animation: Voyag...

Jupiter is so beautiful! And in today's video, much of it is so blue ! ...

Nice discussion AVAO and Ann, and thanks for the context images. I wonder what led to the dark red airplane shape you pointed out in one of your posted images, Ann. Some of these natural questions would be easier to answer if we could observe for a few million years. Since we can't, deducing distan...

Sorry and thanX to bystander for the immediate support. I'll remember it for the future

... Interesting question, Jac. My opinion, or my guess, is that star formation may take place at the tip of long dust lanes, in the same way that star formation often takes place at the tip of dust pillars near hot stars. The reason for star formation at the tip of long dust lanes and at the tip of...

Note that the tiny Cocoon Nebula is located at the tip of a long dark dust lane. ThanX Ann, Great post! One question: For me it looks like the dust lane is GENERATED BY the star as an "exhaust trail" and not the other way around, as is often argued. What is your opinion? Jac https://a4.pb...

The featured recent image of the Cartwheel Galaxy by the Webb Space Telescope reveals new details not only about where stars are forming, but also about activity near the galaxy's central black hole . Why would the Cartwheel Galaxy have a black hole in the middle when CHANDRA absolutely can't see i...

I can see 3 colors besides the white. The blue is obvious. What they call purple I would think is the color that looks more precisely like lavender. And the red looks more like a burgundy color. Am I wrong? I can see hundreds of colors. Interpreting them is the problem. Just because IR is mapped to...

Again, have I discovered, and am suffering from, an acquirable form of colour blindness? Quote blurb, " The featured picture combines visible light from the Hubble Space Telescope in purple, X-ray light from the Chandra X-ray Observatory in blue, and infrared light from the Spitzer Space Teles...

Hello! Isn't the information on this picture a little bit outdated? I think MESSENGER's mission ended in 2015 and is not currently in orbit around Mercury, and the first complete map of the surface was released a couple of years ago. Right? No comment, even if it is holiday time for the editors ;-)...

The article I quoted also says at the end: "Astronomy will be making the simulation available next month, where you can position yourself from anywhere inside the cluster. So cool." I suppose it refers to Astronomy.com site, but I can't find that simulation! :cry: 2014 as source is old. h...

Is there an explanation for the formation of this mesh-like structure, which becomes visible in the IR? Maybe since you now get to see to the inner cores of dense material, your looking at the condensed bars that are driving the formation of all visible material in the galaxy? ThanX for your explan...

The colouring process is not yet well explained (?) for Webb infrared images, but bright white is colder ? Thus the poles ? And, it seems, the Great Red Spot ...

This is a pretty image, expertly processed. However, the red, visible light signal from Hubble (and other visible light sources) is now conflated with the IR signal(s) of JWST- that would be fine if they represented similar spatial and intensity distributions of light, but this isn't necessarily th...

I believe Sundays are days of rest for the staff! New pictures tomorrow! Thanks for the Webb Photo though! :D ok I understand... What I would be interested in is the following: In geck's picture it looks as if the two moons Andrastea (far left) and Metis are moving exactly in the plane of the ring....
