Humans did not evolve for space. Ironically, because we insist on going there anyway, scientists now know from studying ...

The Sun is not nailed to the center of the solar system. It moves, wobbles, and traces a small loop through space, tugged by ...

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

As New Horizons passed Pluto in July 2015, did the dwarf planet alter the probe's trajectory? Douglas Kaupa Council Bluffs, Iowa Pluto did in fact both bend and accelerate the trajectory of New ...

Sixty-six light-years away, an Earth-sized exoplanet completes an orbit in under six hours, skimming around its star at ...

A theory developed to replace dark matter may mean bad news for Planet Nine, a hypothetical as-yet-unseen world in the outer solar system. The odd orbital alignments of icy objects in this region that ...

Shedding light on the gravity of the situation. Most people do not realize that many of the stars and heavenly bodies they see in the sky no longer exist. In fact, many have ceased to exist for ...

More than a 150 years ago, before Neptune was ever sighted in the night sky, French mathematician Urbain Le Verrier predicted the planet’s existence based on small deviations in the motion of Uranus.
