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.
The South Pole–Aitken basin, the oldest and largest lunar impact structure, is a rich site for exploration, with a high chance of a safe landing, abundant resources, and high scientific potential.
Simulations explore the properties of the leading edge of coronal mass ejections; this bright feature is one of the three structural parts commonly seen in these solar eruptions.
A search for the dense star clusters that inhabit the innermost regions of a galaxy finds 325 galaxies with this type of cluster, including 33 galaxies classified as ultra-diffuse galaxies.
