Astronomers have discovered a companion star orbiting kappa Tucanae A that likely sustains a puzzling cloud of ultra-hot dust. Located 70 light-years from Earth, the dust endures extreme conditions near the main star, challenging previous understandings of planetary systems. This finding, achieved through advanced interferometry, could aid future searches for Earth-like exoplanets.

Astronomers using the James Webb Space Telescope have observed vast helium clouds escaping from the super-puff exoplanet WASP-107b, marking the first such detection by the observatory. This finding reveals how intense stellar radiation strips gases from the planet's inflated atmosphere. The observations provide key insights into atmospheric escape and planetary evolution.
