This illustration shows charged particles from Jupiter hitting the face of Europa, separating icy water molecules into hydrogen and oxygen molecules. The scientists believe that some of these newly formed oxygen gases can move into the moon's subsurface ocean, as the circled figure shows. Credit: NASA/JPL-Caltech/SWRI/PU

Will the moon Europa return? The Juno spacecraft discovered oxygen on Jupiter's moon

NASA's Juno spacecraft directly measured charged molecules of oxygen and hydrogen from the atmosphere of Europa, one of Jupiter's largest moons. According to a new study by scientists at SwRI and Princeton, these observations provided important constraints on the potential oxidation of its subsurface ocean

The moon lander Odysseus will stop operating the day after tomorrow (Tuesday 5/3/2024) when darkness falls on its landing area on the side

  • One response
Odysseus landed on its side instead of landing at a vertical angle, which disrupted communication with Earth. Some of the antennas were blocked by the inverted spacecraft, and those that remained exposed were too close to the ground, leading to patchy communications.

long image captionThis is part of the Evolution of the Universe Early Science Survey (CEERS), consisting of several near-infrared points from the NIRCam (Near Infrared Camera) camera on the James Webb Space Telescope. These observations are being made in the same region studied by the Hubble Space Telescope, known as the Extended Groth Belt. Arrows showing the directions north and east show the direction of the image in the sky. It should be noted that the relationship between north and east in the sky (as seen from below) is reversed compared to the half directions on the map of the earth (as seen from above). The image shows invisible near-infrared wavelengths converted to visible colors. The color key shows which NIRCam filters were used to collect the light. The name color of each filter is the visible color that represents the infrared light passing through that filter. The barrel ruler is marked with arc-seconds which are a measure of angular distance in the sky. One arc-second is equal to an angular measurement of 1/3600 of one degree. There are 60 arc-minutes in a degree and 60 arc-seconds in an arc-minute. (The full moon has an angular diameter of about 30 arc-minutes.) The actual size of an object that covers one arc-second in the sky depends on its distance from the telescope.

The James Webb telescope reveals: galaxies in the early universe have a long and flat shape

The first galaxies were much less developed than the spiral and spherical galaxies that exist today, which are actually the result of mergers, both because of the stage of development but also because of the conditions that prevailed at the time
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
Curiosity's rear Hazcam recorded the shadow of the rover's rear in a 12-hour view toward the Gale Basin floor. Several factors caused several artifacts in the image, including a black spot, the sun's distorted appearance, and rows of white pixels extending from the sun. NASA/JPL-Caltech

In the new study, evidence for additional sources of chemical energy, much stronger and more diverse than methane production, was discovered: a group of organic compounds was found that were oxidized, and this points to many chemical pathways for the existence of potential life in the subsurface ocean of Enceladus, because oxidation helps to release chemical energy.
Megan MacArthur, NASA's Mission 65 pilot to the International Space Station, works in the Zero Gravity Science Glove Box and exchanges samples for an experiment called Barrier Sealed Ampoule Coagulation, or SUBSA. The physics experiment investigates experimental methods for coagulating solutions in zero gravity and is expected to lead to reduced fluid movement in the solution, Which will allow for a better distribution of the components and the potential to improve the technology used to produce semiconductor crystals.
