A bright central cluster of stars of various sizes, surrounded by glowing pink and orange clouds of nebular gas. The clouds are uneven, with both smooth regions and thin, threadlike structures. Darker patches appear where dust partially blocks the light, creating contrast against the brightly lit areas.
Ok everyone let's get in formation 💃
NSF–DOE Rubin Observatory’s image of the Trifid and Lagoon Nebulae captures several dazzling open star clusters. 🌌💫 These clusters are young, loosely bound families of stars that will eventually drift apart over millions of years. 🔭🧪

I wrote some articles on Medium, starting with this one, and I expect I’ll write more soon.

"The fallacies behind the cult of Loeb"
New entry in my blog. Other articles have covered the scientific aspects; this one reflects on the social phenomenon. I argue it’s driven by a series of fallacies

Bright green comet with a long blue tail streaking across a star-filled night sky.
Interstellar Comet 3I/ATLAS just delivered its best color image yet—blue CO+ tail, green C₂ head, all classic comet stuff. The twist? A jet is blasting toward the Sun while the tail streams away. Interstellar visitors love drama. More at spaceweather.com.

Images of Comet 3I/ATLAS taken by coronagraphs on GOES-19, STEREO-A and SOHO.
🌟 Comet 3I/ATLAS brightens rapidly! 🌟
As it reached perihelion on Oct. 29, spacecraft watching the Sun saw a sudden surge in brightness. Scientists expect it to emerge from solar conjunction much brighter and easier to see from Earth. 🔭

Lançamos hoje o número 27 da Revista Brasileira de Astronomia. Nesta edição, trazemos artigos sobre formação de galáxias, Nuvens de Magalhães, ondas gravitacionais e sobre o antigo Observatório de São Paulo. A revista pode ser consultada gratuitamente em sab-astro.org.br/wp-content/u...
"O trabalho de catalogação de exoplanetas começou há 30 anos, em 1995, com a identificação do primeiro exoplaneta orbitando uma estrela similar ao nosso Sol."
Destaques da programação:
Barry Barish (Caltech, EUA) – ganhador do Prêmio Nobel de Física em 2017, por seu papel no LIGO;
Mais de 15 palestras convidadas com nomes influentes da área;
Informações no site: agenda.infn.it/event/45592/
Acompanhe todas as novidades no instagram: @lagw.conference
O encontro reunirá cientistas do mundo todo que trabalham na linha de frente da pesquisa em ondas gravitacionais. A programação inclui palestras de especialistas internacionais, sessões de pôsteres, mesas-redondas e apresentações de pesquisas atuais.
Para comemorar uma década da primeira observação direta das ondas gravitacionais, será realizado no Brasil o evento:

Edge-on spiral galaxy angled pointing lower left to upper right. It's glowing with a bright core that's cut with the dark veins of dust clouds. The background is peppered with a myriad of colorful stars and distant galaxies in black space.
A smooth, cigar-shaped galaxy angled pointing lower left to upper right glowing with a bright core. Two bright stars beam just to the upper left and lower right of the galaxy. The background is peppered with a myriad of colorful stars and distant galaxies in black space.
A face-on spiral with a bright core and sweeping arms knotted with blue clusters of star-forming regions. The background is peppered with a myriad of colorful stars and distant galaxies in black space.
A face-on spiral with a bright core and a single thin arm wrapping all the way around, almost looking like a ring. Two bright blue stars beam above and to the lower left of the galaxy, with a third yellow star to the lower right. The background is peppered with a myriad of colorful stars and distant galaxies in black space.
Happy birthday, Vera Rubin! 🥳✨
What better way to celebrate than with NSF–DOE Rubin Observatory's view of galaxies SHE studied?
NGC 4343, 4526, 4535, and 4378 are just a few gems from our Cosmic Treasure Chest. Explore them and more at skyviewer.app 🔭🧪
A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions. All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black.
A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars.

It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry.

O cair da noite da quinta-feira (26/06) foi espetacular: a olho nu, o colorido crepúsculo foi palco para Mercúrio e a Lua, ao telescópio, a estrela 79 Geminorum surgia após ter sido ocultada pela Lua.
Pra hoje (27/06): A Lua hoje vai estar mais alta no céu e vc vai poder observar por mais tempo.
Thick and thin disk galaxies observed by the James Webb Space Telescope in a new study published in Monthly Notices of the Royal Astronomical Society.

Galaxies, through thick and thin…🌌
Astronomers used the James Webb Space Telescope to look at 111 edge-on disk galaxies of various ages to better understand changes in galaxy disks over time, and how star-formation shapes them.
