A global network of robotic telescopes helps test a new way of measuring oscillation modes of massive stars; successful measurements of these modes may unlock these stars’ interior structures.
The interstellar media of dwarf galaxies — defined in this work as galaxies with total stellar mass less than about 3 billion times the mass of the Sun — haven’t changed much over the past 7.8 billion years.
If current or future spacecraft cross a solar current sheet, it would give researchers entirely new insight into these structures, which are key to understanding solar eruptions.
Researchers discover a protocluster just 800 million years after the Big Bang; the protocluster is estimated to involve into a galaxy cluster with a mass of 7 quadrillion Suns.
Coronal “spiders” or coronal cloud prominences are strands of cool, tenuous solar plasma suspended up to 200,000 km in the corona; these features tend to shrink and disappear rather than erupt.
If you have tickets to visit GJ 367b, cancel ‘em — the planet has a molten dayside surface, is likely uncomfortably hot, and has lost all of its surface volatiles, recent JWST observations reveal.
