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 🔭🧪
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.

Introducing...your sneak peek at the cosmos captured by NSF–DOE Vera C. Rubin Observatory!

Can you guess these regions of sky?

This is just a small peek...join us at 11am US EDT for your full First Look at how Rubin will #CaptureTheCosmos! 🔭🧪

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. 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. 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.

HiPOD: Chasmata Boundary

The science of goal of this observation is to investigate the superposition relationship between the layered rocks and wall rock spurs along the boundary between Ophir Chasma and Candor Chasma.

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.

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.

Uma combinação muito peculiar de luzes e sombras cria duas formações que duram algumas horas no início do quarto crescente: o X e o V lunar.
