The latest Swedish-led search for technosignatures in the form of Dyson Spheres has again come up empty-handed.

Among the rarest objects in the universe, high redshift quasars --- of the sort that formed before the universe was even a billion years-old ---

Solar system simulations starting from varied initial conditions suggest that Earth-like planets can emerge naturally from planet formation.

On a mostly flat plain an hour north of Stockholm lies a collection of large burial mounds dating from an ancient culture at least 2500 years old.

One of our solar system's biggest puzzles has long been why Venus has no moon. Often referred to as Earth's twin, Venus is almost the same mass and size as our own planet.

If some aspects of cosmic topology turn out to be true, the idea that starships might voyage the cosmos over hundreds of thousands of light years without ever returning to the same neck of space-time could be problematic.

NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft has made a once-in-a-lifetime find of a newly formed crater on the Moon's near side, some 330 km from the edge of the Mare Crisium.

Astronomers have potentially detected the first known second-generation planet; in this case, a Jupiter-like planet that likely formed from the accretion of debris cast off by a dying stellar white dwarf.

Mercury remains one of our solar system's most elusive and difficult planets to study. It's easier to send probes to the icy moons of Saturn or Jupiter, or even Pluto, than to land on our innermost planet of Mercury.

Lunar meteorites --- literally pieces of the Moon's surface that have been displaced into Earth or solar orbit and have burned their way through
