Hoy, Día de las Madres, expreso mi reconocimiento a quienes desempeñan este papel, ya que con su amor incondicional, guía y dedicación a los hijos, representan una inspiración en la vida.
Felicidades !
Muchas gracias a la Universidad de Xalapa por otorgarme un reconocimiento a mi labor en el marco del Día Internacional de la Mujer, desde el espacio en el que me encuentre seguiré trabajando para el fortalecimiento de la democracia en nuestro País.

Gomez's Hamburger: A Cosmic Burger in Sagittarius This delectable deep-space object, formally known as IRAS 18059-3211 (or Go 26-17), is nicknamed Gomez's Hamburger after its discoverer, astronomer Arturo Gomez, who spotted it in 1985 on survey plates from Cerro Tololo Inter-American Observatory.The iconic Hubble image perfectly captures why: the "buns" are lobes of dust illuminated by light reflecting off tiny particles, while the dark "patty" is a thick, edge-on circumsellar disk of dust blocking our view of the central star.
Classic Hubble view of Gomez's Hamburger (NASA/ESA Hubble, 2002): The hot central star (~10,000°C surface temperature) is completely hidden behind the dusty disk, with reflected light creating the symmetric "bun" glow.Originally thought to be a proto-planetary nebula—a short-lived phase (~1,000 years) where a dying Sun-like star sheds its outer layers before becoming a full planetary nebula—later studies reclassified it.Modern understanding (from ~2008 onward, based on CO observations with the Submillimeter Array and other data):It's actually a young pre-main-sequence A-type star (hot, massive, ~2–4 solar masses) surrounded by a Keplerian-rotating protoplanetary disk.
The disk is edge-on to our line of sight, creating the striking bifurcation.
Distance: Closer than initially estimated, around ~900–1,000 light-years (not 6,500–10,000 ly as in early proto-planetary models).
Another detailed Hubble capture emphasizing the dark lane and bipolar reflection lobes.
Recent views (e.g., processed James Webb Space Telescope data) highlight infrared details of the disk, potentially revealing planet-forming regions.

No special sauce needed—just pure cosmic wonder!Image credits: Primary classic view from NASA, ESA, and the Hubble Heritage Team (STScI/AURA); acknowledgment to A. Gomez.

This is the one that broke astronomy’s mind in 1845.Lord Rosse pointed his 72-inch Leviathan telescope (the largest in the world at the time) toward a faint smudge in Canes Venatici and saw something no human had ever seen before: a cosmic whirlpool. Not a cloud, not a star cluster, but a pinwheel of light with arms that clearly spiraled. He sketched it, published it, and quietly detonated the idea that everything beyond the Milky Way was just shapeless fog. The age of galaxies had begun, and M51 was Patient Zero.Fast-forward 31 million years (the time its light has been racing toward us) and here it is in full, savage glory.The Whirlpool Galaxy is the poster child for “grand-design” spirals: two perfect logarithmic arms glowing electric blue with newborn star clusters so bright they look like diamonds spilled across velvet. Those arms aren’t random; they’re density waves squeezing interstellar gas like a cosmic python until it collapses into blazing new suns. Every knot you see along the arms is a stellar maternity ward of hundreds of thousands of stars being born right now (right now meaning 31 million years ago).At the tip of the upper arm sits NGC 5195, the little troublemaker. It’s not just posing for the portrait; it’s the reason the whole show exists. A few hundred million years ago this irregular dwarf galaxy came in hot from behind, punched straight through the disk, and yanked one of the arms into that perfect, almost artificial-looking hook. Gravitational slingshot on a galactic scale. The collision lit the fuse, and the fireworks are still going off.Seen face-on from 31 million light-years away, M51 is close enough and bright enough that even small backyard telescopes reveal the spiral arms on a good night. It’s the galaxy that turns first-time observers into lifelong addicts.This isn’t just a pretty picture. It’s the original evidence that the universe is full of islands of stars, each one a cosmos unto itself.And it all started with an Irish lord, a giant mirror, and one perfect sketch that changed everything we thought we knew about our place in the dark.Messier 51: the galaxy that taught us the universe has structure, drama, and a flair for the spectacular.
Desde la #AMMEL extendemos nuestro reconocimiento a la Dra. @claudia_diazt por su dedicación y profesionalismo durante su gestión como Magistrada en el @TEVeracruz fortaleciendo la democracia y promoviendo la justicia electoral en México.
