Space scientists are puzzled after the discovery of a bizarre planet — shaped like a lemon. Astronomers spotted the unusual exoplanet orbiting a pulsar, with a bizarre ovoid form sculpted by extreme gravitational forces.

Visitors to the Sunwheel can see the sun rising and setting over the winter solstice stones from approximately Dec. 16 through Dec. 26. During this period the sun appears to rise at a fixed spot on the southeast horizon and set in a fixed southwest direction for more than a week.

Astronomers using the James Webb Space Telescope report that a powerful gamma-ray burst detected in March may have been produced by the explosion of a massive star just 730 million years after the Big Bang.

Among the more puzzling cosmic phenomena discovered over the past few decades are brief and very bright flashes of blue and ultraviolet light that gradually fade away, leaving behind faint X-ray and radio emissions.

Cosmic dawn galaxies seen by JWST reveal hidden clues about dark matter and keep rival theories about its true nature alive.

Researchers have found a razor-thin, rotating string of galaxies inside a massive cosmic filament, revealing unexpected alignments that challenge models of how galaxies gain their spin. An internation

Across modern astronomy, the most striking pattern is not a single spectacular discovery but a drumbeat of similar clues. Wherever telescopes and probes look with enough sensitivity, they keep turning up the same life-friendly ingredients, from complex ...

The first pulsar was discovered in 1967 by Jocelyn Bell Burnell. Finding these mysterious signals forever changed astronomy.
