A thin atmosphere on a small world beyond Pluto - Nature Astronomy
3+ day, 23+ hour ago (297+ words) Nature Astronomy (2026) Cite this article Stellar occultation observations reveal that the trans-Neptunian object 2002 XV93, which has a radius of only ~250 km, is surrounded by a very tenuous atmosphere. The result shows that even a small distant icy body can host a…...
Relics of the first stars spotted in a distant, ultra-faint galaxy
3+ day, 23+ hour ago (54+ words) An observation of an ultra-faint galaxy, captured as it was shortly after the Big Bang, indicates the presence of material from the first generation of stars. An observation of an ultra-faint galaxy, captured as it was shortly after the Big…...
Efficient robot navigation inspired by honeybee learning flights
3+ day, 23+ hour ago (1586+ words) Navigation is a crucial capability for both animals and robots. Although tiny flying insects can robustly navigate over long distances1, state-of-the-art robot navigation methods are computationally expensive and therefore restricted to large robots2, 3. Here we propose ‘Bee-Nav’, a highly efficient navigation strategy…...

Fast and furious: the gaseous outflows of quasars in the early Universe were extreme
3+ day, 23+ hour ago (69+ words) Observations from the James Webb Space Telescope reveal that extremely fast, galaxy-scale outflows from luminous objects called quasars were much more frequent, and on average more powerful, about one billion years after the Big Bang than at later cosmic epochs....

An ultra-faint, chemically primitive galaxy forming in the reionization era
3+ day, 23+ hour ago (1661+ words) The formation of the first stars and galaxies marked the onset of chemical enrichment, yet direct observations of such primordial systems remain elusive. Here we present James Webb Space Telescope spectroscopic observations of LAP1-B, an ultra-faint galaxy at redshift zspec…...
