A team using the Hobby-Eberly Telescope processed 600 million spectra to build the first large-scale intensity map of Lyman-alpha emissions from 9 to 11 billion years ago, exposing faint galaxies and intergalactic gas invisible to conventional surveys.

South Africa's MeerKAT radio telescope has discovered a record-breaking hydroxyl gigamaser in a merging galaxy system, shattering the previous distance record by a factor of two.

Six months of observations of the third interstellar object ever detected have uncovered water, methane, and hydrogen cyanide in its coma--and a Jupiter flyby on March 16 could yield the closest-ever look at an interstellar visitor.

A 15-hour JWST observation has produced the first three-dimensional map of Uranus's ionosphere, confirming decades-long atmospheric cooling and exposing how the planet's tilted, offset magnetic field sculpts complex auroral structures unlike any seen elsewhere in the solar system.

CDG-2, a near-invisible galaxy 300 million light-years away, is the first detected solely through its globular cluster population. Roughly 99% of its mass is dark matter.
