🧵 This breathtaking image from #JWST, published last April 29, depicts a cosmic field filled with thousands of galaxies. THOUSANDS OF GALAXIES! Stars, marked by diffraction spikes, are within the Milky Way. Reference➡️ esawebb.org/images/potm2... 🔭 🧪 #stellarastro #cosmology #Universe #Webb

The image shows an area of deep space teeming with thousands of galaxies, like a bright mosaic on a deep black background. In the center, slightly lower, stands out a group of gold-white galaxies that shine brightly, like a cluster of gems. Around them, galaxies of various shapes dot the scene: some are spirals with curved arms, others are elliptical and smooth, still others have distorted shapes. The colors vary from white and blue for nearby galaxies to red for distant ones. Stars of the Milky Way appear as bright points with thin rays radiating outward, like small sparkling spikes. The overall effect is a dense and vibrant cosmic carpet, full of light and movement.

🧵 In case you missed it, here’s the #JWST wide-field view of the huge galaxy cluster MACS-J0417.5-1154, known for its stunning gravitational lensing effects and its wild ongoing merger dance. 🔭 🧪 ⚛️ ➡️ webbtelescope.org/content…. #cosmology #extragalactic #space #Astronomy #universe 1/8

The following caption comes from this web page: https://science.nasa.gov/asset/webb/macs-j04175-1154-wide-field-nircam-image/

"A cosmic question mark appears amid a powerful gravitational lens in the James Webb Space Telescope’s wide-field view of the galaxy cluster MACS-J0417.5-1154. Gravitational lensing occurs when something is so massive, like this galaxy cluster, that it warps the fabric of space-time itself, creating a natural funhouse-mirror effect that also magnifies galaxies behind it.
The rarely seen type of lensing captured here, which astronomers term hyperbolic umbilic, created five repeated images of one galaxy pair. The red, elongated member of this pair traces the familiar shape of a question mark across the sky due to the distortion, with another unrelated galaxy happening to be in just the right space-time to appear like the question mark’s dot – especially for humans who love to recognize familiar shapes and patterns."

🧵 This image provides an overview of the 25 brightest stars in the night sky (as seen by humans). It shows them in true color, highlighting their beauty and diversity. ➡️ apod.nasa.gov/apod/ap25061... For more, read the thread. 🔭 🧪 #stellarastro #science #Universe #Astronomy #HistSci

The image presents a visual representation of the 25 brightest stars in the night sky, shown in true color against a black background that simulates the starry sky. The stars are arranged in a grid, each accompanied by its name standardized by the International Astronomical Union (IAU). Each star is depicted as a bright point of light with spikes, showing varying sizes and colors that reflect their apparent magnitude and surface temperature: some appear white, others yellow-orange or reddish. There are no lines or constellations depicted, just isolated stars with their names written in white lettering. The overall effect is that of a stylized night sky, with a clear, scientific aesthetic designed to highlight the brightness and color of each star.
The stars are: Sirius, Canopus, Rigil Kentaurus, Arcturus, Vega, Capella, Rigel, Procyon, Achernar, Betelgeuse, Hadar, Altair, Acrux, Aldebaran, Antares, Spica, Pollux, Fomalhaut, Deneb, Mimosa, Regulus, Adhara, Shaula, Castor, Gacrux.

🧵 Here is Messier 106 (or NGC 4258), a true cosmic marvel in the constellation Canes Venatici. Image Credit: NASA, ESO , NAOJ, Giovanni Paglioli; Assembling and Processing: R. Colombari and R. Gendler ➡️ apod.nasa.gov/apod/ap19031... 🔭 🧪 #science #universe #extragalactic #astronomy 1/5

The image features Messier 106, a big spiral galaxy. Its center glows bright white from a huge black hole gobbling gas. Blue arms full of young stars sweep out wide, crossed by dark red dust lanes and pink hydrogen clouds near the middle. Faint reddish extra arms hint at hidden jets. It stretches approximately 135,000 light-years across in the dark sky.

🔭 🧪 #Universe #cosmology 🧵 Here is an extraordinary image of the star cluster RCW 38, captured by ESO's VISTA telescope in the Atacama Desert, Chile. The cluster's image, located about 5500 ly away in the constellation Vela, is 80 million pixels in size. Reference➡️ www.eso.org/public/unite...
