This image, taken by NASA's Perseverance rover on Aug. 6, 2021, shows the hole drilled into Martian rock in preparation for the rover's first attempt to collect a sample. It was captured by one of the rover's cameras in what the rover's science team called "cobblestone" in the area. The crater floor is broken and rough" in Jezero Crater. Credit: NASA/JPL-Caltech

Cosmic disappearance: NASA solves the mystery of shrinking planets

Analysis of Martian seismic data recorded by the InSight mission revealed that the liquid iron core of Mars is surrounded by a layer of molten silicate 150 km thick, resulting in a smaller and denser core than previously suggested. (Graphic: Thibaut Roger, NCCR Planet S / ETH Zurich)

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.

The image shows a deep image of the Pandora galaxy cluster, or Abell 2744, using data from NASA's James Webb Space Telescope. Following the image, an international team led by Penn State University researchers confirmed the distance of these ancient galaxies and inferred their properties using new spectroscopic data James B. Telescope - Information on light emitted across the entire electromagnetic spectrum. About 33 billion light-years away, these particularly distant galaxies provide insights into how primordial galaxies could have formed.

Japanese researchers from Nagoya University have revealed new aspects of the interaction between mast plants or mass seeding plants, i.e. plants that spread their seeds at once like Sasa bamboo and field mice. Their research reveals that mouse behavior (which varies between species, and varies according to environmental conditions and seasons) plays a crucial role in seed dispersal and ecosystem health in forests, and challenges existing theories about seed storage and consumption.
