At center right is a compact star cluster composed of luminous red, blue, and white points of light. Faint jets with clumpy, diffuse material extend in various directions from the bright cluster. Above and to the right is a smaller cluster of stars. Translucent red wisps of material stretch across the scene. Background galaxies are scattered across this swath of space, appearing as small blue-white and orange-white dots or fuzzy, thin disks. The background of space, which is easiest to see in the top-left corner, is black.

The Extreme Outer Galaxy—the region more than 58,000 light-years from the Milky Way’s galactic center—is pretty extreme! 😎 #NASAWebb observed a portion of Digel Cloud 2, revealing newly formed stars that are expelling jets of material from their poles: https://bit.ly/4qpOdu4

Two galaxies side by side. The galaxy at the top left appears smaller in size and is a bright glowing spiral with clearly defined arms. A larger blue galaxy dominates the full right two-thirds. This galaxy is more irregularly shaped, with a glowing central bar, and varying regions of concentrated hues of blue. The background of space is black with various stars and galaxies in the distance.

The galaxy on the left in this Hubble image is actually larger! The dimmer galaxy in Arp 4 is 65 million light-years from Earth, while the bright one lies 675 million light-years away! It’s determined that the further galaxy is much larger. Credit: NASA/ESA.

Artist’s concept titled “TRAPPIST-1 System” showing a section of the red dwarf host star at the bottom and seven circles vertically aligned and labeled b to h from bottom to top against a solid black background. A half circle on the bottom represents the host star, TRAPPIST-1, which has a bright orange mottled surface with flares that extend outward. Artist’s concepts for the planets b, c, d, and e are encased in their respective circles, indicating that scientists have reported on their Webb observations for these planets. Planets b and c have brighter circles around them to indicate that scientists have more confidence in their interpretation, while the circles around d and e are fainter to indicate the data is still under study. Planets f, g, and h are depicted as circles with white dashed lines. A question mark is in each of these three circles to indicate that the atmospheric statuses of these planets are still to be determined as the Webb data continues to be analyzed.

Graphic titled “TRAPPIST-1 System Versus The Solar System, Orbit Comparison.” The inner solar system is at left and labeled “Inner Solar System.” The Sun is depicted as a bright white circle. 4 planets' orbital paths are labeled: Mercury, Venus, Earth, and Mars. 2 lines extend from between the Sun and Mercury to an overlay of the TRAPPIST-1 system at right. 7 rings, representing the orbital paths of the 7 planets, surround the star. They are labeled starting with b, the closest planet to the star, and ending with h, the planet farthest away. Obital areas of planets b, c, and d are shaded red, signifying they are too close to be in the host star’s habitable zone. Orbital areas of planets e, f, and g are green, signifying they are in the area where conditions are just right for liquid water to exist on a planet’s surface. The green area is labeled “Habitable Zone.” Orbital area of planet h is blue to indicate the planet is too far away to be in the host star’s habitable zone.

Artist’s concept of the TRAPPIST-1 system, which is known to have seven Earth-sized rocky planets orbiting a red dwarf star. The host star, located in the background, is depicted as a bright white circle. It is surrounded by a yellow glow that fades to orange near the edges of the frame. The seven planets appear in the foreground, with their nightsides, the side facing away from the host star, facing the viewer. The planets are depicted as red-brown spheres. Many distant galaxies and stars faintly appear in the background. Text in bottom left corner reads “Artist’s Concept.

A nebula appears like a transparent bubble with a white edge, inside which are two hemispheres of orange clouds being blown out from the center, split by a dark vertical lane, giving the overall appearance of a see-through skull with a brain inside, as seen from above. A few stars appear with eight points, and small background galaxies can be seen around and through the outer bubble.

Astronomers are losing their minds over #NASAWebb’s latest images of the very brainy-looking nebula PMR 1. Its distinctive form is the result of a dying star expelling its outer layers: https://news.stsci.edu/4tVQccE 🔭 🧪

A globular star cluster. Numerous stars are spread throughout on a black background. Many appear as fuzzy blue and orange orbs. Scattered throughout are far smaller stars appearing as white and orange dots. These stars are concentrated in the center, but grow more spread out further away.

The blue stars within globular cluster NGC 6397 have used up their hydrogen fuel, and are now fusing helium, which fuses at higher temperatures, giving them their blue color—as seen in this Hubble image: https://bit.ly/4tsl7wU

Side-by-side images of the same nebula show how differently it appears in near-infrared, on the left, versus mid-infrared light, on the right. Left image is labeled NIRCam and the right is labeled MIRI. In near-infrared, the nebula’s outer bubble has a white edge and its inner clouds are orange, with a distinct dark lane cutting vertically through the center. Stars and background galaxies appear around the nebula and through the outer bubble. In mid-infrared, the outer bubble has a bluish tint and there is more material in the inner clouds, which are colored off-white. The vertical dark lane is still present but more interrupted and covered by the clouds. Material appears to be erupting out the top of the nebula, and this effect is mirrored to a lesser degree at the bottom, opposite end.

A tiny portion of the Rosette Nebula. Very dark gray material shaped like a shark’s fin extends from just below top left all the way down to the lower right corner and back up toward the top right. It looks like thick smoke that has billowed out irregularly, thicker along the line from top left to bottom right. Behind the dark gray on the left side, from the bottom left to top center, there are streaks that appear light orange and yellow. The background at top left is hazier and some blues are covered in semi-transparent orange wisps, which makes sections take on green hues. In the bottom right, the background is bluer. There are a few bright red and purple stars scattered along the right half, mostly toward the bottom. The largest star is at right-center, just at the edge. It is red and has four diffraction spikes.

In 2024, #Hubble observed a portion of the Rosette Nebula—a vast star-forming region located 5,200 light-years away. Hydrogen, oxygen, nitrogen, and dark clouds of dust contribute to this mesmerizing scene, which is four light-years long: https://bit.ly/4rndjuB

Hubble de la NASA revela un caótico lugar de nacimiento de planetas, el más grande que se haya descubierto - NASA Ciencia El hallazgo marca un nuevo hito para Hubble y arroja luz sobre cómo se pueden formar planetas en entornos extremos.

Los astrónomos que utilizan el telescopio espacial Hubble de la NASA han fotografiado el disco protoplanetario más grande que se haya observado alrededor de una estrella joven.

A spiral galaxy with a bright supermassive black hole. The galaxy appears cloudy white with orange-red regions filled with stars that spiral outward from the bright center. A large eight-pronged diffraction pattern emanates from the central black hole. Many orange and red stars and galaxies are strewn about. The background of space is black.

Galaxy NGC 7469 has one of the most studied black holes in the universe. #NASAWebb’s resolution and sensitivity has made it easier to study the large amount of dust and compact nature of the region.

Discovering the Least-Massive Brown Dwarfs Known with the James Webb Space Telescope Stars exist across a wide range of masses, some more massive than the Sun and some less massive. If a star is less massive than roughly 8% of the Sun's mass, or 80 times the mass of Jupiter, its center is too cool to sustain hydrogen fusion. These stars...

Astronomers have used #NASAWebb—most powerful infrared telescope to date—to search for brown dwarfs at very low masses in a nearby nebula that contains newborn stars.
