Scientists using NASA's Transiting Exoplanet Survey Satellite (TESS) discovered an exoplanet, which NASA defines as “any planet beyond our solar system.” What's False However, the “strange signals” ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

Deep in the older, denser reaches of the Milky Way, there is a red dwarf star that shouldn’t exist — or at least, its family ...

Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

Life. But how would we know it? The world of astronomy is abuzz with excitement. Have we discovered the first-ever evidence of off-world life? Is the signal extracted from the interstellar noise a ...

The discovery overturns traditional models that predicted gas giants in outer orbits and suggests planets can form in gas-poor environments.

A team of scientists at the Institute for Advanced Study School of Natural Sciences in Princeton, New Jersey, might have found a new dwarf planet, potentially leading to more evidence of a theoretical ...

Astronomers have long been on the hunt for "Planet Nine," a hypothetical planet that lies within our solar system just beyond Neptune. Scientific evidence has alternately pointed to and against the ...
