With 3I/ATLAS slated to make its Earth tour in two days, amateur photographers and astronomers alike are scrambling to catch sight of the interstellar comet. Our intergalactic visitor will officially make its closest approach on December 19.

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.

Astronomers have recently detected a colossal object at the edge of our solar system, sparking excitement and curiosity within the scientific community. This discovery could provide crucial insights into the outer regions of our solar system and the ...

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

“The fact that we can now watch stars explode and immediately see the structure of the material being blasted into space is remarkable,” said the University of Michigan astronomer and a co-author of a study published on December 5 in the journal Nature Astronomy. “It opens a new window into some of the most dramatic events in the universe.”

Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic explosion ever observed, a gamma-ray burst that lasted nearly seven hours.

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

For around a year now, the Sidewalk Astronomers have been meeting regularly in D.C. to show people that gazing at the stars can be accessible to anyone.
