NGC4258 es una galaxia muy importante para medir el ritmo de expansión del universo, porque se han podido medir en ella los brillos de varios tipos de estrellas, tanto con el telescopio espacial Hubble como con el James Webb.
badastronomy.beehiiv.com/p/jwst-yup-t...

Tres imágenes de la galaxia referida en el post. Es una espiral vista de forma oblicua, con un bulbo central brillante, un poco rojizo, rodeado por los brazos azulados, bastante apretados. Bandas oscuras de polvo oscurecen la imagen, sobre todo alrededor del bulbo central, sirviendo de transición con la zona de los brazos. La de la izquierda la muestra completa, tal como se podría ver con el ojo humano. La segunda también muestra lo que se llama "el visible". Se centra en la zona más interior y deja ver grandes girones de nebulosas oscuras y rojizas, brotadas de formación estelar, que siguen el camino espiral de los brazos. La tercera imagen, a la derecha, muestra la misma zona ampliada de la segunda foto, pero tal como la ve el telescopio James Webb. Se aprecia un brillante halo azulado envolviendo la parte del bulbo central y los girones nebulosos más rojos, destacando más aún con respecto al fondo azulado del bulbo.

Comic. PERSON: Sure, when *Einstein* suggests using the Lorentz transform to explain the connection between velocity and time, people call him a genius. But when *I* suggest it, it’s “basic physics” and “undergraduate stuff.” PERSON 2 with white hat: Such a double standard!

Space Force satellite catalog is now at object 65973, expected to pass the 66000 mark by tomorrow.

Object 00001 was the rocket upper stage from Sputnik 1.

Yup. Seventh one is for #Galileo | #spaceArt #sciArt

poster illustrated with the Galileo spacecraft at Jupiter. the moon Europa can be seen just behind the spacecraft. The title reads Galileo but also titles the atmospheric probe which was never named.

A veces se representa a los científicos como seres andrajosos, desaliñados y trastornados. Aunque la imagen es exagerada, si tenemos en cuenta la precariedad, la inestabilidad laboral, la escasa remuneración y la explotación laboral que sufren, tampoco sería de extrañar que así fuera… #inktober2025

The search for life's building blocks on Enceladus just got more complicated. Experiments show that radiation can also produce organics from ingredients found on the icy moon. 🔭 🧪 eos.org/articles/spa...

Space Radiation Can Produce Some Organic Molecules Detected on Icy Moons - Eos

As missions prepare to visit ocean worlds like Enceladus and Europa, new findings show scientists must first learn to distinguish between radiation-made organics and those born in a subsurface sea.

Huzzah, it’s #PortfolioDay !

I’m Danielle and I paint and illustrate spacecraft, planets, and interesting landscapes in watercolor and ink. Fond of ink textures and pointillism. No AI here, just space and rocks/geology. 🪐🪨🚀

Prints and originals available at planetaryartist.com

Thanks for looking!

DUST OF OSIRIS by Danielle Rose Baker. A painting of the top-down view of the opened sample return capsule from the OSIRIS-REx mission to asteroid Bennu. Circular sections and hexagonal bolts are seen among the rocky material in the middle ring, framed by lotus flower motifs and patterned circles with geometric ink designs drawn in an ancient Egyptian style with gold accents. A ring of painted turquoise, lapis and carnelian rectangles accented with gold surrounds the inkwork. Inspired by the decorative motifs of Tutankhamen’s treasures, and the Art Deco-tinged Egyptian Revival movement that arose from the discovery of said treasures.

DIANA PIERCES THE AZURE SKY by Danielle Rose Baker. An ink illustration of a Saturn V rocket and launch tower during the launch of Apollo IV. The top two-thirds is a roiling sky of clouds rendered in blue, dark teal and navy inks, some with shimmering effects. Outlined against this, the launch tower is seen in shades of brown-orange. The rocket is bathed in warm light and yellow-tinged exhaust expands below, with dark shapes outlining the base of the launch pad.

HUES OF VENUS by Danielle Rose Baker. A pearlescent false-color watercolor painting on black paper of the cloudy atmosphere of Venus as seen by the JAXA Atatsuki spacecraft in 2020. In this view, the clouds are seen in swirls and ribbons of gold and dark blue, combining to blue-grays.

UBEHEBE CRATER by Danielle Rose Baker. A watercolor painting of Ubehebe Crater at Death Valley National Park. An explosive volcanic crater dusted with snow against an overcast sky. The crater wall has many layers, in shades of brown, tan and orange. The foreground is darker brown, with lighter splotches of snow.
