Belatedly, some words about this Recent Submissions thread...

Tunç Tezel, that's a fascinating comparison between the winter sky and the summer sky. The individual stars are brighter in the winter, but the Milky Way is brighter in the summer!

Gilles Cohen, that's a fascinating winter landscape with an enormous-looking Sun halo in the sky.

François-Xavier Lousson, I love your image! I love the faintly colored rays that seem to emanate from the Sun, I'm fascinated by the subsun, and I just love the diamond dust glittering in the sunlight. And I love the soft, muted colors of the entire scene, and the elegant composition with horizontal and vertical lines and the apparent layer of clouds between one mountain and the next.

Brendan Alexander, your picture reminds me a little of François-Xavier Lousson's. Your stars are like his diamond dust, and your striated, multi-colored aurora is like his faintly multicolored Sun rays. Oh, and your picture is beautiful, too!

Shahrin Ahmad, that's a very interesting comparison of the angular sizes of the planets. Why is Venus clearly brighter than Jupiter, even though Jupiter is larger in angular size? The answer must be that because Venus is so much closer to the Sun, its smaller disk receives much more sunlight than the larger disk of Jupiter. And because Venus is almost white, it reflects most of the light that it receives. Jupiter is not quite as white as Venus, but clearly the main reason between the apparent brightness difference is simply that the sunlight that reaches Jupiter is much fainter than the sunlight that reaches Venus.

In another picture you compare the angular sizes of Mars and Saturn. Because of its wide bright rings, Saturn's angular size is larger than that of Mars. The color of Saturn is also lighter and more reflective than the color of Mars. But because Mars is so much closer to the Sun than Saturn, it receives much more sunlight than Saturn. And at opposition, like now, Mars is therefore brighter than Saturn.

That's a fine thin sliver of a Moon, Jens Hackmann.

José Joaquín Pérez, that's a very fine portrait of NGC 2547! On your own homepage, you compare this cluster to the Pleiades. I, too, think it looks quite a lot like the Pleiades.

Máximo Ruiz, that's a fine portrait of NGC 4565, also called (I think) the Needle galaxy.

Adam Block, thank you so much for this wonderful portrait of an incredibly ignored Virgo Cluster Messier galaxy! Note the very bright yellow bulge, the overexposed and therefore white-looking nuclear region, the thin elegant dust lanes of the bar, the finely textured bluish arms with some, but not many and not very bright, emission nebulae. Also note the rather large and dust-free outer disk, dominated by intermediate-aged stars.

Efrain Morales, that's a very fine and very detailed portrait of Mars. I can actually see that the North Polar Cap is shrinking.

Jerry Lodriguss, that's a fine portrait of M100. You captured the bright center, the brownish old population of the inner disk and the blue arms very well. I'm also glad that your picture shows us so many of the satellite galaxies of M100.

Paolo Candy, thank you for that annotated image of Comet Garradd passing in front of a background galaxy!

Marco Angelini, that's a beautiful portrait of M81 and M82.

Adam Block, that's a really fascinating planetary nebula. Its round shape and uniform bluish color is very interesting, and it is sporting that bright blue star on its periphery like the stone of an engagement ring.

Robert Gendler, that's another Hubble picture that looks so great because you have processed it in RGB. I recommend everybody to follow the link to check out Robert's own homepage and see the largest version of this picture. Note the fascinating satellite galaxies at nine o'clock.

Bob and Janice Fera, that's a very beautiful portrait of the NGC 2264 region in Monoceros.

Mikael Sundbart, that's a quite fantastic portrait of a rectangular piece of sky between the walls of the Örebro Castle in Sweden. Really fascinating!

Dani Caxete, I don't know how interested I am in Tiangong, but I really appreciate those "squares of Moon samples". Note how square number one seems to sample the brightest Moon terrain, and square number six the darkest! Note, too, how square number three seems to be situated on the underside of the chin of the Lady in the Moon, above her prominent Adam's apple and below her broad mouth.

Philippe Durville, I like your portrait of the Orion Nebula and the Running Man Nebula, which seem to be tossed like a small rowing-boat on a stormy sea of red.

And Dean Salman, you have made the Cone Nebula region look like a peninsula, looking out over a sea of red on its right.

That's a fine sundog, Chris Howard, very colorful.

Fred Burgeot, your beautiful Jupiter drawings deservedly became the Astronomy Picture of the Day. Congratulations!

Michael J. O'Leary, what a fascinating aurora!

Manos Kardasis, thank you for showing us Jupiter in all its glory, and Ganymede, too!

John Martinez, and B.J. Fulton, I love that Wolf-Rayet star and its bubble! Thank you!

Pavel Presnyakov, that's a splendid Mars portrait, fantastically detailed! And Mario Weigand, your Mars portrait is beautiful, too.

Thanks to everyone who contributed images here!
