Even the best telescopes can’t see exoplanets. It’s all about watching for jiggly stars, blue shifts, and transits.

Astronomers from the University of Hawai‘i at Mānoa and other institutions have identified a new wide-orbit planet and a stellar companion around two young ultracool dwarfs located in the Taurus Molecular Cloud,

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

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.

Far above the Sun’s bright surface, a steady stream of charged particles accelerates into space. This outflow, known as the solar wind, starts nearly motionless and then races outward at hundreds of kilometers per second.

Astronomers have produced the first continuous, two-dimensional maps of the outer edge of the sun's atmosphere, a shifting, frothy boundary that marks where solar winds escape the sun's magnetic grasp.

A scientist has identified a possible astronomical explanation for the Star of Bethlehem, as described in the Bible
