Scientists are exploring neutron star interiors using gravitational waves as "cosmic tuning forks." Analyzing reverberations from neutron star collisions could reveal the composition of these ultra-dense stellar remnants. Research focuses on how the post-collision remnant vibrates spacetime, emitting gravitational waves with frequencies tied to the star's internal structure.
The European Space Agency's XMM-Newton X-ray observatory identified two previously unknown supernova remnants on the Large Magellanic Cloud's outskirts. These remnants, J0624-6948 and J0614-7251, challenge previous assumptions about the distribution of ionized gas in galaxies. Their existence suggests more active galactic outskirts due to interactions between the Large Magellanic Cloud, the Milky Way, and the Small Magellanic Cloud.
Research from the University of Reading indicates that subsurface oceans on icy moons like Europa and Enceladus may be more difficult to probe for life. Distinct ocean layers can impede the movement of biological signatures from the ocean floor to the surface, potentially masking evidence of life. This challenges current strategies for detecting life, suggesting future missions may require more invasive methods, such as deploying submarines.
