Hubble has found a growing ten-sided atmospheric wave around Saturn’s south pole—the first large regular-sided jet seen there. Saturn has long been known for a strange shape in its clouds. A vast hexagon circles the planet’s north pole, holding its form for more than four decades. Now astronomers have found something that looks as if […]

Imagine turning a piece of ancient wood toward the light and finding the faint remains of someone’s handwriting. What did that person need to say? And how could we place their message on a calendar almost two thousand years later? Ancient inscriptions bring those questions together. Their words can preserve a royal decree, a business […]

Twenty-seven faint objects beyond Neptune are giving astronomers a rare look at the planet-building material that survived when the outer solar system stopped growing. The outer solar system is not empty. Beyond Neptune, in the cold region known as the Kuiper Belt, countless small bodies travel around the Sun. Most are so faint that even […]

The objects are unusually soft in X-rays but bright in extreme ultraviolet light—exactly the combination that makes them difficult to find and potentially important to the history of stars and galaxies. A galaxy can be full of powerful objects and still keep some of them hidden in plain sight. That is what makes a new […]

A terrace project in Rebild uncovered about 18.5 kilograms of Viking-Age silver. The objects show how wealth moved, was measured and was hidden in tenth-century Denmark. A new terrace was supposed to change a garden. Instead, a few minutes of digging opened a small window onto the Viking Age. In Rebild, northern Denmark, a homeowner […]
