Rare distant object 2020 VN40 found in perfect sync with Neptune

A team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has discovered a rare object far beyond Neptune, from a class known as trans-Neptunian objects, that is moving in rhythm with the giant planet. ...

Earth was born with water—no delivery needed

Alone among known planets, Earth has vast oceans on its surface and its landmasses are marked with lakes and extensive river drainage systems. Water is the biosphere's lifeblood, and without it, Earth would be just another ...

This Earth-sized exoplanet is on a death spiral

Our circumstances here on the wondrous, life-supporting Earth can give us a false understanding of what the universe is really like. But our blue-skied, temperate planet is the extreme exception when it comes to other worlds. ...

Scores of exoplanets may be larger than realized

In new research, University of California, Irvine astronomers describe how more than 200 known exoplanets are likely much larger than previously thought. It's a finding that could change which distant worlds researchers consider ...

Primordial black hole flybys could alter exoplanet orbits

Though our solar system and the movement of its planets appear relatively sedate, there are many things that could upset the balance. Anything with enough mass that got close enough could disrupt planetary orbits. This includes ...
