The presence of a 34-solar-mass brown dwarf companion to an ultra-hot Jupiter suggests that the hot Jupiter must have formed within 1.5 au of its host star to remain dynamically stable.

Using gravitational flow simulations, researchers link smooth areas on the face of a comet to a single event 600–1,200 years ago, possibly connected to multiple close encounters with Jupiter.

Sgr A East strongly overlaps with plasma associated with the Milky Way’s central supermassive black hole, but new efforts to disentangle this emission have successfully isolated the remnant’s emission.

Slightly smaller than Jupiter but roughly 80 times as massive, TOI-2155b can provide a valuable test for models of stellar-mass objects near the hydrogen-burning mass limit.

Discovered just 6 billion years after the Big Bang, AT2025wet is the highest-redshift non-jetted tidal disruption event known, allowing researchers to probe the missing-energy puzzle.

The disks around young high-mass stars survive for roughly 3.72 million years, and those around low-mass stars survive for 7.20 million years, though the distributions for both populations are quite broad.
