After four centuries of advances, astronomers now capture the Sun’s swirling, dynamic features in stunning detail.

Nearly all stars are found inside or around galaxies, but there are ways for stars to escape into intergalactic space.

Proximate to the Moon, Regulus (Alpha Leonis), exhibiting an apparent magnitude of 1.3, will be visible. The angular separation between the Moon and Regulus is expected to change on an hourly basis.

Jupiter achieves opposition on January 10, providing optimal viewing of its extensive atmospheric details and dynamic Galilean moon transits, including a rare overlapping shadow transit of Callisto.

Because rogue planets don’t orbit a host star, they can’t be found using astronomers’ typical go-to methods: radial velocity or transits. (Radial velocity measures the way a star wobbles as an unseen ...

A new extreme trans-Neptunian object (ETNO), designated 2023 KQ14 (Ammonite), has been discovered, representing only the fourth known sednoid – a class of ETNOs with highly distant and elongated ...

Lunar Prospector launched on January 6, 1998, as the third mission within NASA’s Discovery Program, which emphasizes frequent ...

The observation period features lunar appulses with Saturn, Neptune, and Uranus, complemented by transits of Jupiter's Galilean moons (Io and Europa) and their shadows across the gas giant's disk.

The COSMO-SkyMed Second Generation (CSG-3) satellite, a critical synthetic aperture radar asset for Italian Earth observation, is slated for launch on December 31, 2025, aboard a Falcon 9 from ...
