Euclid space telescope sees gorgeous cosmic cloud | Space photo of the day for Nov. 18, 2025

Interstellar comet 3I/ATLAS has been captured in a new image following its close approach to the sun. This observation provides valuable insights into the evolution of interstellar objects, showcasing the comet's unique characteristics.

Tonight, the moon reaches its farthest distance from Earth since March 2020, a phenomenon that will not occur again until 2043. However, this event will not be visible to observers on Earth.

A Dreamliner pilot captured stunning images of a G4 geomagnetic storm, showcasing a breathtaking northern lights display from an altitude of 36,000 feet. The event provided a rare opportunity for the pilot to witness and document the natural phenomenon in its full glory.

Astronomer Gianluca Masi captured stunning images of the comet C/2025 K1 (ATLAS) as it broke apart after being heated by the sun. The photographs reveal the comet's fragmentation, providing a unique glimpse into the behavior of celestial bodies in our solar system.

The Very Large Telescope's interferometer has successfully targeted four lasers toward the Tarantula Nebula, resulting in the creation of an artificial star. This innovative technique aims to enhance astronomical observations and improve the understanding of this region of space.

Regular stars undergo a process of collapse and death once they exhaust their nuclear fuel. However, white dwarfs, which are the remnants of such stars, persist indefinitely, remaining stable over time. This phenomenon raises questions about the long-term existence of these stellar cores and their role in the universe.

A newly discovered companion star has been found orbiting a huge red giant star, raising concerns about potential disruptions in the complex processes surrounding these celestial bodies. The presence of this close companion could lead to further complications in the dynamics of the red giant star, which is already a subject of intense study in the field of astrophysics.
