When a supergiant star runs out of fuel, it expands and then rapidly collapses on itself. This act creates a neutron star—an object denser than our sun crammed into a space 13 to 18 miles wide. In such a heavily condensed stellar environment, most electrons combine with protons to make neutrons, resulting in a dense ball of matter consisting mainly of neutrons. Researchers try to understand the forces that control this process by creating dense matter in the laboratory through colliding neutron-rich nuclei and taking detailed measurements.</description> <link>https://phys.org/news/2024-04-merging-nuclear-physics-astronomical-advance.html</link> <category>Astronomy </category> <pubDate>Fri, 19 Apr 2024 13:36:44 EDT</pubDate> <guid isPermaLink="false">news632752598</guid> <media:thumbnail url="https://scx1.b-cdn.net/csz/news/tmb/2024/frib-researchers-lead.jpg" width="90" height="90" /> </item> <item> <title>Two NASA sounding rockets launch from Alaska during solar flare</title> <description>Two Black Brant IX sounding rockets launched from Poker Flat Research Range in Fairbanks, Alaska, April 17, 2024, during an M-class solar flare for NASA's sounding rocket solar flare campaign.</description> <link>https://phys.org/news/2024-04-nasa-rockets-alaska-solar-flare.html</link> <category>Space Exploration Planetary Sciences </category> <pubDate>Fri, 19 Apr 2024 13:31:29 EDT</pubDate> <guid isPermaLink="false">news632752286</guid> <media:thumbnail url="https://scx1.b-cdn.net/csz/news/tmb/2024/two-nasa-sounding-rock.jpg" width="90" height="90" /> </item> <item> <title>The 'devil comet' 12P/Pons-Brooks has finally become visible from Australia.
