A newly found object could be a dwarf planet that contradicts the Planet Nine hypothesis.

Astronomers have spotted a supermassive black hole ripping apart and devouring a star in colliding galaxies. It is only the second time a tidal disruption event has been seen in interacting galaxies.

A supernova remnant (SNR) discovered by astrophysicist Miroslav Filipović of Western Sydney University displays an astonishingly spherical shape.

Using a newly developed adaptive optics system called Cona, scientists peered through Earth's turbulent air to reveal the sun's corona in astonishing clarity.

A number of groups and individuals say there's a need to protect lunar history before it's too late.

The mystery surrounding a strange cosmic object, or 'long-period transient,' has deepened. This object is bursting with X-rays, and astronomers describe it as unlike anything seen before.

The 2025 Humans to the Moon & Mars Summit (H2M2) will be held May 28 and 29 in Washington, D.C., and will include panels discussing the future of human space exploration.

A massive galaxy cluster, Abell S1063, forms a gravitation lens, revealing the warped light from more distant galaxies dating back to the early universe in this James Webb Space Telescope image.

An abrupt change in Antarctica has caused the continent to gain ice. But this increase, documented in NASA satellite data, is a temporary anomaly rather than an indication that global warming has reversed, scientists say.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
