Hours before its death, a massive star violently reshuffled its insides then exploded into Cassiopeia A. NASA’s Chandra data reveals this last-minute chaos, offering new clues into how stars live, die & transform the cosmos

This nice Hubble image shows the intriguing nebula RCW 7 dotted with stars.

Also known as Sh 2-302 and Gum 6, it is located some 5,300 ly away in Puppis.

RCW 7 is an H II region, containing a massive binary protostar, IRAS 07299-1651, which is estimated to have a minimum total mass of...

🔭 🧪
This Hubble image features the RCW 7 nebula, a cloud of interstellar gas and dust with a faint pink glow due to ionized hydrogen. The background is bluish and studded with stars. Dense, curling clouds surround massive protostars at the center. These emit ultraviolet and infrared light. The brightest stars in the foreground don't belong to the nebula. The ensemble appears as a mix of soft light and shadow, with contrasts between the dark clouds and the bright glow.

Tangle of craters along the southern part of the first quarter Moon last night at 144x. Herschel is the small shadowed crater near the upper center. Below it is Ptolemaeus. Right of Ptolemaeus is Albategnius. Below Ptolemaeus is Alphonsus, and below that is Arzachel. #astronomy #astrophotography

The largest photomosaic of the Andromeda galaxy, assembled from Hubble observations, took more than 10 years of data collecting and was created from more than 600 snapshots!

➡️ And it's available for download in really large sizes: go.nasa.gov/44Uvyhc 🔭 🧪
The Andromeda galaxy, a spiral galaxy, spreads across the width. It is tilted nearly edge-on to our line of sight so that it appears as an extreme oval on its side. The borders of the galaxy are jagged because the image is a mosaic of smaller, square images. The outer edges of the galaxy are blue, while the inner two-thirds are yellowish with a bright, central core. Dark, dusty filamentary clouds wrap around the outer half of the galaxy’s disk. At 10 o’clock, a smaller dwarf elliptical galaxy forms a fuzzy, yellow blob. Hubble’s sharp vision distinguishes about 200 million stars within the image. The background of space is black. There are what appears to be steps toward the bottom, mainly toward the middle, which indicates where no data were taken.

Astronomers may have found evidence of still-forming planets hidden in this close-up of the star RIK 113, taken with our VLT 📸 🪐

This and previous ALMA data suggest that the disc around the star may be shaped by hidden planets.

This is RCW126, a Hydrogen Alpha nebula region 6,500 light years away in the constellation of Scorpius. Captured over multiple nights in May and June 2025 using my Edge HD8 telescope and ASI1600MM Pro camera. 25 hours of total imaging time #astrophotography @kat-astro-bot.bsky.social
RCW 126 is classified as an H II region – a cloud of ionized hydrogen gas excited by young, massive stars. It was cataloged in the 1960 Rodgers-Campbell-Whiteoak (RCW) survey of southern Hα emission nebulae. Specifically, RCW 126 is noted as a low-surface-brightness H II region, meaning its optical emission is relatively faint compared to brighter nebulae. It corresponds to Gum 62 in the Gum catalog of nebulae and is part of the grouping of H II regions known as the Cat’s Paw Nebula complex (NGC 6334). There is no indication that RCW 126 is a supernova remnant; its properties are consistent with an ionized star-forming nebula rather than an exploded star. RCW 126 lies in the southern Milky Way in the constellation Scorpius, near the tail of the Scorpion. It is situated only a few degrees from the bright star λ Scorpii (Shaula). Its equatorial coordinates are approximately RA 17ʰ13ᵐ–17ʰ17ᵐ, Dec −36°18′ (J2000). This places RCW 126 in the same sky region as the NGC 6334 star-forming complex. Indeed, RCW 126 is often considered an outlying part of the Cat’s Paw Nebula (NGC 6334) system of H II regions in Scorpius. In Galactic terms, it lies in the inner Galaxy (near galactic longitude l ≈ 351°), in a rich star-forming arm segment. The presence of ongoing star formation is a defining characteristic of RCW 126. Besides the IR-bright protostar(s), the nebula and its molecular cloud exhibit other star-forming signposts: dense clumps, likely maser emission and molecular outflows have been reported in the region, indicative of active protostellar accretion and feedback. (For example, radio studies have noted a north–south velocity gradient in the molecular gas of RCW 126, which could be related to outflow motions.) In summary, RCW 126 is not just an ionized gas cloud but a cradle of new stars, including at least one high-mass star and numerous lower-mass members forming in the embedded cluster.

Located just a few dozen kilometres from Madrid, the Cebreros ground station was inaugurated in 2005 as the second deep space antenna in ESA’s Estrack satellite tracking network. With its 35-metre dish, it provides routine support to ESA deep-space missions, like: Mars Express, BepiColombo, Juice and Hera. Observations of our neighbouring galaxy, Andromeda, made using ESA’s Flyeye telescope. Andromeda appears so large in Earth’s sky that in angular size it is six times the diameter of the full Moon and it can be seen with the unaided eye in dark skies. The NASA/ESA/CSA James Webb Space Telescope recently imaged the Sombrero galaxy with its NIRCam camera, which shows dust from the galaxy’s outer ring blocking stellar light from stars within the galaxy. In the central region of the galaxy, This galaxy is called NGC 685 and is classified as a barred spiral because its feathery spiral arms sprout from the ends of a bar of stars at the galaxy’s centre.

The Cygnus Wall is a giant cloud of hydrogen gas that is ionized by nearby stars, so it glows. From end to end, it's about 20 LY long. It's 1,500 LY away, so this is really what it looked like 1,500 years ago. HOO color palette. #astronomy #astrophotography #astro #science #cygnus #space #nebula
