This is a new image from #JWST.

The bright points with spikes are stars in the Milky Way.

Everything else is a galaxy.

you’re as beautiful as the stars above btw
Hubble’s visible-light view of a star-forming region, the Pillars of Creation, shows darker pillars that rise from the bottom to the top of the screen, ending in three points. The background is opaque, set off in yellow and green toward the bottom and blue and purple at the top. A handful of stars of various sizes appear. A colorful, glowing nebula that reaches beyond the top and bottom of the image. This translucent cloud of gas holds wispy and thin filaments with hard edges in some places, and puffy and opaque in others. Blue, red, and yellow colors mix together, showing light emitted by different types of atoms in the hot gas. Scattered across the colorful nebula are bright and point-like foreground and background stars. The background is black. Viewed like a distorted donut, an inner circular nebula region glows in dark blue shades with faint stars viewed within. It's surrounded by a ring of bright teal, then an outer ring of reddish-orange. Black space with distant, faint stars fills the background. Thousands of bright stars shine against black space, more tightly condensed near the image’s center. The stars glint in shades of white, blue, and red, and diffraction spikes are visible around the foreground stars.

stressed about the state of the world and need some space? me too! here you go 🌌
A spiral galaxy seen close up and almost face on. It is filled with puffy, patchy clouds of hot gas and dust. Red, orange and yellow colours indicate light emitted by different particles. The brightest colours are in the centre and along the two spiral arms, which wind out from the centre. Star clusters hide in the gas along the arms. A few large, bright white stars are prominent in the foreground, near to us. A Hubble image of the globular cluster Omega Centauri, a collection of myriad stars colored red, white, and blue on the black background of space. Several bright stars shine in yellow, orange, and white hues. The stars have diffraction spikes, and two are particularly large just above and below the image's center. The background is full of dark brown dust and gas that covers most of the diagonal right half of the view, with pale blue gas glowing in the upper left section. The Crab Nebula. An oval with complex structure extends from lower left to upper right against a black background. On the oval’s exterior lie curtains of glowing yellow and green fluffy material. Its interior shell shows large-scale loops of mottled filaments of yellow-white and green, studded with clumps and knots. Translucent thin ribbons of smoky blue lie within the remnant’s interior, brightest toward its center. The blue material follows different directions throughout, including sometimes sharply curving away from certain regions within the remnant. A faint, wispy ring of blue material encircles the very center of the nebula. Around and within the supernova remnant are many points of blue, green, purple, and white light.

i feel like we all need another timeline cleanser
A large galaxy is at center, and a significantly smaller galaxy is to its left. The large galaxy is mostly face-on, but the top appears slightly tilted away. It has several rings. Its circular core is bright white at the very center, but light yellow overall. Going outward, there are gaps between the rings. The core is surrounded by two slightly lighter yellow rings, which also appear to be overlapping. The next ring is slightly more transparent and yellow. The two or three rings that are farther out are bluer, sometimes with blue clumps. The widest ring is also blue, but also the most transparent. At 9 o’clock is a small dwarf galaxy. It is about the same size as the yellow core of the Bullseye. The dwarf galaxy is blue, with many dots. It looks like the edge of the Bullseye might touch the dwarf galaxy. Both galaxies are set on the black background of space, which is dotted with a range of galaxies in different shapes, colors, and sizes, along with one foreground star at left. A concentration of bright blue stars occupies the bottom right corner of the image. At bottom center within them is a small blue bubble. The stars and bubble are part of a diffuse dwarf galaxy that extends beyond the image border. Background galaxies are scattered across the image, with some particularly prominent spirals located at upper left and upper right. The background of space is black. This is a highly detailed composite image of a star-forming region of space known as 30 Doradus, shaped like a bouquet, or a maple leaf. X-ray wind and gas takes the shape of a massive purple and pink bouquet with an extended central flower, or perhaps a leaf from a maple tree. The hazy, mottled shape occupies much of the image, positioned just to our left of center, tilted slightly to our left. Inside the purple and pink gas and wind cloud are red and orange veins, and pockets of bright white light. The red and orange veins represent energy ejected by supernovas, carried on cosmically strong winds. The pockets of white light represent clusters of young stars. One cluster at the heart of 30 Doradus houses the most massive stars astronomers have ever found. The hazy purple and pink bouquet is surrounded by glowing dots of green, white, orange, and red. A second mottled purple cloud shape, which resembles a ring of smoke, sits in our lower righthand corner. This is a composite image of star cluster NGC 602, in vibrant and festive colors. The shape of the star cluster strongly resembles a holiday wreath. The cluster includes a giant dust cloud ring, shown in greens, yellows, blues, and oranges. The green hues and feathery edges of the ring cloud create the appearance of a wreath made of evergreen boughs. Hints of red representing X-rays provide shading, highlighting layers within the wreath-like ring cloud. The image is aglow with specks and dots of colorful, festive light, in blues, golds, whites, oranges, and reds. These lights represent stars within the cluster. Some of the lights gleam with diffraction spikes, while others emit a warm, diffuse glow. Upon closer inspection, many of the glowing specks have spiraling arms, indicating that they are, in fact, distant galaxies.

🔭 🧪 #extragalactic #JWST🧵
1/
This tantalizing vibrant color image (released in Dec. 2024) of the young star cluster NGC 602 uses Chandra X-ray data (in red) and JWST data (in various infrared colors).

Reference➡️ chandra.cfa.harvard.edu/photo/2024/n...

The combined use of X-rays and infrared
The image features the star cluster NGC 602, which comprises a giant ring of dust clouds, colored in green, yellow, blue and orange. The green hues and feathery edges create the appearance of a crown of evergreen branches. Hints of red, representing X-rays, provide shading, highlighting the inner layers. The image is illuminated by dots and blobs of colored light, in shades of blue, gold, white, orange and red, representing the stars within the cluster. Some lights shine with diffraction spikes, others emit a diffuse glow. Many of the bright dots have spiral arms, indicating that they are, in fact, distant galaxies.

On Generative AI Security
On Generative AI Security - Schneier on Security
Microsoft’s AI Red Team just published “Lessons from Red Teaming 100 Generative AI Products.” Their blog post lists “three takeaways,” but the eight lessons in the report itself are more useful: Understand what the system can do and where it is applied. You don’t have to compute gradients to break an AI system. AI red teaming is not safety benchmarking. Automation can help cover more of the risk landscape. The human element of AI red teaming is crucial. Responsible AI harms are pervasive but difficult to measure. LLMs amplify existing security risks and introduce new ones...

A very fascinating paper went up on the arXiv today!

Jesse Han & El-Badry et al. reanalysed the 21 known 'hypervelocity' stars in the #milkyway.

They find strong evidence that the LMC (Large Milky/Magellanic Cloud) has a supermassive black hole at its core! 🤯 arxiv.org/abs/2502.00102
A figure from the paper (Figure 4). It shows the locations of known hypervelocity stars as black circles, with the predicted overdensity that the LMC would cause shown in red. Full caption: Predicted on-sky overdensity of hypervelocity stars originating from a 6 × 105M⊙ supermassive black hole in the LMC. The black open circles denote the Galactic coordinates of hypervelocity stars detected in the HVS Survey, while the grey-shaded regions mark areas excluded from the survey. The current position of the LMC is illustrated with a representative image, and its orbital trajectory is drawn with a red arrow. The forward model incorporating an SMBH in the LMC along with the selection effects of the HVS Survey predicts a prominent overdensity of HVS in the region enclosed by the red contours. The overdensity arises because stars are boosted in the direction of the LMC’s orbit. This model accurately reproduces the observed overdensity location, supporting the hypothesis of an SMBH in the LMC as a source of these stars.

A supernova and its host galaxy 💫🔭

Today's NASA/ESA #HubbleSpaceTelescope image is of LEDA 132905 and a supernova named SN 2022abvt which was discovered in late 2022.

🔗 esahubble.org/images/potw2...
In the exact centre a supernova is seen as a small but bright blue dot. It lies atop a spiral galaxy, close to the glowing centre and next to some bright patches of blue stars in the galaxy. A small number of more minor galaxies are visible around the comparatively large spiral as small glowing discs, while further distant galaxies are seen as mere orangish spots and smudges, all on a black background.

may i offer you a space rose? 🌹🌌
The upper galaxy is labelled UGC 1810 by itself, but together with its collisional partners is known as Arp 273. The overall shape of the UGC 1810 -- in particular its blue outer ring -- is likely a result of wild and violent gravitational interactions. The blue color of the outer ring at the top is caused by massive stars that are blue hot and have formed only in the past few million years. The inner part of the upper galaxy -- itself an older spiral galaxy -- appears redder and threaded with cool filamentary dust. A few bright stars appear well in the foreground, unrelated to colliding galaxies, while several far-distant galaxies are visible in the background.
