Hot end for Peregrine lander: Burn up in atmosphere on Thursday, 19/1/24

  • One response
The spacecraft failed to reach lunar orbit due to a fuel leak that was discovered immediately upon its ejection from the upper stage of the launcher. Now NASA is helping Astrobotics investigate the malfunction
This image from Webb's MIRI (mid-infrared) camera shows the star system Beta Pictoris. A flat disk of dust fragments, formed by collisions between planetesimals (orange), dominates the landscape and is called the "main disk plane". In the lower left corner, Webb showed the true extent of the secondary disk (cyan (turquoise), which is inclined 5 degrees relative to the primary disk. Webb also discovered a previously unseen feature called the "cat's tail." A coronagraph (a black circle and two small disks) was used to block The light of the central star. Scale bar shows that the disks of Beta Peak (pictoris) span hundreds of astronomical units (AU), where one AU is the average distance from Earth to the Sun. (In our solar system, Neptune orbits the Sun at a distance of 30 AU) in this image , light at a wavelength of 15.5 microns is shown in cyan (turquoise) and 23 microns in orange (F1550C and F2300C filters, respectively).

The Webb Space Telescope discovered a 'cat's tail' made of dust in the Beta Pictoris system

  • No comments
Beta Pictoris is a solar system in the making and relatively close so that the gas disks can be seen. It turns out that Webb was able to discover a structure that was not noticed in photographs with less sensitive instruments, thus he discovered a disk of gas tilted from our main disk and because of our vantage point it looks like a cat's tail

An example of a supernova detected by the Dark Energy Survey within the field covered by one of the few detectors in the Dark Energy Camera. The supernova exploded in a spiral galaxy with redshift = 0.04528, which corresponds to a light travel time of about 0.6 billion years. For comparison, the quasar on the right has a redshift of 3.979 and a light travel time of 11.5 billion years. Credit DES Collaboration/NOIRLab/NSF/AURA/M.

The scientists then used advanced machine learning techniques to help classify the supernovae
Researchers at the University of Queensland have found that humans can understand the emotional state of chickens from the sounds of their clucking. This ability, which is not affected by previous experience with chickens, has significant implications for improving poultry welfare and can assist in the development of artificial intelligence-based surveillance systems.

New research shows great apes have an extraordinary social memory, recognizing former group members even after more than 25 years. This finding, which indicates a significant cognitive similarity between great apes and humans, emphasizes the depth and duration of social ties in our animal relatives. The study found the longest-lasting non-human social memories ever recorded. Photo: Johns Hopkins University

Yesterday, after it separated from the upper stage of the Vulcan launcher, it became clear that there is a fuel leak from the spacecraft's engines that change its balance and do not allow it to generate electricity from solar energy. The Astrobotics company says that they will try to turn it into a lunar compass, even if only for a short time * On board the spaceship were five dedicated NASA instruments

An international team of astronomers compiled and reprocessed observations of the extrasolar planet WASP‑121 b collected by the Hubble Space Telescope in 2016, 2018 and 2019 and noticed weather patterns on its surface. It is a hot Jupiter-type planet - that is, on the order of Jupiter but very close to its sun
