Hubble observations reveal a giant, evolving ten-sided atmospheric wave at Saturn's south pole.

A Nature study infers a 200–400 °C temperature contrast between the mantle beneath Mars's southern highlands and northern lowlands.

NASA's new Roman Space Telescope has launched, beginning a three-month journey toward the orbit where it will map the universe at extraordinary speed.

A neural algorithm turns decades of VLBA frames of blazar 3C 345 into a continuous plasma-jet video that maps local flow speeds.

JWST spectra show massive quiet galaxies carry far more faint stars than a Milky Way mix would allow, which could raise early galaxy masses by about four times.

S301 is the fastest known star in the Milky Way, and its extreme orbit may let astronomers measure Sagittarius A*'s spin.

The ALICE experiment used oxygen and neon nuclei to make quark–gluon plasma and read a nucleus's hidden shape from the particle spray it left behind.

Hubble locked in an early Milky Way merger about 12 billion years ago — a dwarf galaxy called LKH that crashed in long before the famous ones.
