An image of Messier 51 has been uploaded. Continuing with the project to capture all Messier objects with high resolution telescopes, this time, M51 has been the chosen one (and I hope to upload two more Messier galaxies today). You can find it at:
This image of a tiny nebula was taken already several weeks ago. I took it at the suggestion of Don Goldman. This nebula has an unusual structure that took several years to be understood. You can find the image and all details and explanations at:
An image of the elliptical galaxy M87 has been uploaded. Besides its fame (won a year ago due to the first image os a black hole, in M87’s center), M87 has other interesting characteristics that, together with its image and details can be found at:
An image of a quite interesting nebula has been uploaded. It was already time to finish it, as this image was taken nearly two years ago… This nebula was studied with the Spitzer Telescope around the same time I was taking this image. You will find more information about this nebula and characteristics at:
This region, as many emission nebulae, contains numerous interesting objects, mostly Herbig-Haro objects (up to 24 of the 25 Herbig Haro objects present in this area can be found in the mosaic), but also the very active IRS1, with IR emission and embedded with numerous stars in their first stages of formation as well a known MASER source.
Another image taken from the Northern Hemisphere has been uploaded. This time, an emission nebula, the Pacman Nebula. This nebula has many peculiarities and I specially like the pillars (neatly pointed to their originators, the massive and hot O and B stars in the cluster nearby) and the many Bok globules.
An image of a barred spiral galaxy has been uploaded. This galaxy is peculiar in that it harbors a supermassive central black hole with about 73 million solar masses, but its nucleus is not at all active, because it is not accreting matter.You will find it at:
