- The first satellite made of wood — yes, wood — has made it to spaceqz.com The first satellite made of wood — yes, wood — has made it to space
LignoSat's wooden satellite is offering a greener alternative for the industry
> Meghan Everett, NASA’s deputy chief scientist for the International Space Station program, said, “While some of you might think that wood in space seems a little counterintuitive, researchers hope this investigation demonstrates that a wooden satellite can be more sustainable and less polluting for the environment than conventional satellites.” > > LignoSat was created by researchers at Kyoto University along with a homebuilding company, according to Reuters. > > “With timber, a material we can produce by ourselves, we will be able to build houses, live and work in space forever,” Takao Doi, an astronaut who now studies human space activities at Kyoto University, told Reuters.
- Nearly three years since launch, Webb is a hit among astronomersarstechnica.com Nearly three years since launch, Webb is a hit among astronomers
Demand for observing time on Webb outpaces supply by a factor of nine.
> The Space Telescope Science Institute, which operates Webb on behalf of NASA and its international partners, said last week that it received 2,377 unique proposals from science teams seeking observing time on the observatory. The institute released a call for proposals earlier this year for the so-called "Cycle 4" series of observations with Webb. > > This volume of proposals represents around 78,000 hours of observing time with Webb, nine times more than the telescope's available capacity for scientific observations in this cycle. The previous observing cycle had a similar "oversubscription rate" but had less overall observing time available to the science community.
> More than 600 scientists will review the proposals and select the most promising ones for time on Webb. The largest share of proposals would involve observing "high-redshift" galaxies among the first generation of galaxies that formed after the Big Bang. Galaxies this old and distant have their light stretched to longer wavelengths due to the expansion of the Universe. Research involving exoplanet atmospheres and stars and stellar populations were the second- and third-most popular science categories in this cycle.

- JWST: MIRI - IC 2163 and NGC 2207
[Image description: Two spiral galaxies take up almost the entire view and appear to be overlapping. They are angled from top left to bottom right. The galaxy at left, IC 2163, is smaller and more compact than the galaxy at right, NGC 2207. The background of space is black, dotted with tiny foreground stars and extremely distant galaxies.]

- LDN 43: The Cosmic Bat Nebula
What is the most spook-tacular nebula in the galaxy? One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic bat flying amongst the stars on a dark Halloween night. Located about 1400 light years away in the constellation Ophiuchus, this molecular cloud is dense enough to block light not only from background stars, but from wisps of gas lit up by the nearby reflection nebula LBN 7. Far from being a harbinger of death, this 12-light year-long filament of gas and dust is actually a stellar nursery. Glowing with eerie light, the bat is lit up from inside by dense gaseous knots that have just formed young stars.
- JWST: NIRCam/MIRI - NGC 602
[Image description: A star cluster is shown inside a large nebula of many-coloured gas and dust. The material forms dark ridges and peaks of gas and dust surrounding the cluster, lit on the inner side, while layers of diffuse, translucent clouds blanket over them. Around and within the gas, a huge number of distant galaxies can be seen, some quite large, as well as a few stars nearer to us which are very large and bright.]

[Image Description: A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics. They have a variety of sizes depending on their brightness and distance from us in the cluster, and different colours reflecting different types of star. Patches of billowing red gas can be seen in and around the cluster, lit up by the stars. Small stars in the cluster blend into a background of distant stars and galaxies on black.]

- JWST: NIRCam/MIRI - Arp 107
[Image description: A pair of interacting galaxies. The larger of the two galaxies is slightly right of centre, and is composed of a hazy, bright, white centre and a ring of gaseous filaments, which are different shades of red and orange. Toward the bottom left and bottom right of the ring are filaments of gas spiralling inward toward the core. At the top left of the ring is a noticeable gap, bordered by two large, orange pockets of dust and gas. The smaller galaxy is made of hazy and white gas and dust, which become more diffuse further away from its centre. To this galaxy’s bottom left, there is a smaller, more diffuse gas cloud that wafts outward toward the edges of the image. Many red, orange, and white galaxies are spread throughout, with some being hazier in appearance and others having more defined spiral patterns.]

[Image description: At centre 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, though there are patches and a noticeable gap in the top left corner that reveal the black background of space. Background galaxies are scattered across this swath of space, appearing as small blue-white and orange-white dots or fuzzy, thin discs. There is one noticeably larger blue-white point with diffraction spikes, a foreground star in the upper right.]

Large, bright stars surrounded by six long points of light are dotted over the image, as well as some small, point-like stars embedded in the clouds. The clouds are lit up in blue close to the stars; orange colours show clouds that glow in infrared light.]

At the top of the ring are three very bright spots with diffraction spikes coming off them, right next to each other: these are copies of a single quasar in the lensed galaxy, duplicated by the gravitational lens. In the centre of the ring, the elliptical galaxy doing the lensing appears as a small blue dot. The background is black and empty.]

- JWST: NIRCam - Protostar L1527
[Image description: A growing protostar embedded within a molecular cloud. The center of the image shows a bright, red region, where the growing protostar resides, with a thin, gray lane of matter cutting through it horizontally, which is the protostar’s accretion disk. Above and below this region are blue triangular-shaped molecular clouds, which give the overall object an hourglass shape. The areas in the molecular clouds closest to the protostar have more pronounced plumes of blue gas. There are red, yellow, orange, blue, and green stars and galaxies scattered across the background.]

Among them are distorted linear features, which mostly appear to follow invisible concentric circles curving around the centre of the image. The linear features are created when the light of a background galaxy is bent and magnified through gravitational lensing. A variety of brightly coloured, red and blue galaxies of various shapes are scattered across the image, making it feel densely populated.]

- Family whose roof was damaged by space debris files claims against NASAarstechnica.com Family whose roof was damaged by space debris files claims against NASA
"Whatever NASA does is going to send a strong signal to the space industry."
>Alejandro Otero, owner of the Naples, Florida, home struck by the debris, was not home when part of a battery pack from the International Space Station crashed through his home on March 8. His son Daniel, 19, was home but escaped injury. NASA has confirmed the 1.6-pound object, made of the metal alloy Inconel, was part of a battery pack jettisoned from the space station in 2021.
>An attorney for the Otero family, Mica Nguyen Worthy, told Ars that she has asked NASA for "in excess of $80,000" for non-insured property damage loss, business interruption damages, emotional and mental anguish damages, and the costs for assistance from third parties.
>"We intentionally kept it very reasonable because we did not want it to appear to NASA that my clients are seeking a windfall," Worthy said.
Seems reasonable to me. If I accidentally caused damages to someone's home, I'd certainly be held liable. But, I'm just some guy.
