Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape consisting of bright blue stars surrounding a yellow-white concentration of central stars. This concentration has a diagonal line of stars across it, called a bar. The galaxy is tilted inward to our view from Earth. A white S-shaped line slightly across the top is the Hubble image of an asteroid hovering across the field of view.. It looks dashed because the image is a composite of several exposures of the asteroid flying like a race car. Credit: NASA, ESA, PG Martín (Autonomous University of Madrid), J. DePasquale (STScI).

Discovering new asteroids in old Hubble images

  • One response
Astronomers re-examined 37,000 images taken by Hubble over 19 years of objects in deep space. The reward was finding 1701 asteroid orbits in the asteroid belt, of which 1031 are uncatalogued asteroids. About 400 of these uncatalogued asteroids are roughly less than a kilometer in size

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

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.
thanks for the correction. The corrected translation would be: SwRI scientists used data from the James Webb Space Telescope to model the geothermal processes in the subsurface that may explain how methane reached the surface of Eris and Maki Maki, two dwarf planets in the distant Kuiper Belt. The figure suggests three possibilities, including the likelihood that liquid water exists within these icy bodies at the edge of the solar system, far from the sun's heat.

Saturn's surprise: NASA discovered an energy source and a basic molecule for life on Enceladus

  • 20 תגובות
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.

Jupiter (Webb NIRCam image): This image of Jupiter from NASA's James Webb Space Telescope NIRCam (Near Infrared Camera) shows spectacular detail of the planet, which is impressive in infrared light. In this image, brightness indicates a high altitude . The many white "dots" and "marks" are likely very high-altitude cloud edges of condensed convection. The auroras, shown in red in this image, extend to higher altitudes over both the planet's north and south poles. In contrast, dark bands north The equatorial region has no cloud caps.
