So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases the size of the Moon’s orbit. This means that the Moon gets slightly farther ...

Science advances through data that don't fit our current understanding. At least that was Thomas Kuhn's theory in his famous ...

Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white dwarf star questions how Halla could exist. Credit: Space.com | animation ...

Earth’s history has been punctuated by at least five major ice ages. Some of these frigid periods of prolonged global cooling saw much of our planet locked in ice and snow for 100 million years. It ...

The classical picture of star and planet formation suggests that a star’s rotational axis and the orbital planes of its planets should be aligned. However, exoplanetary systems have considerable ...

Recently identified exoplanet, BD+05 4868 b, is shedding its surface in a comet-like tail as it disintegrates under extreme stellar heat. SETI Live host Beth Johnson spoke with National University of ...

Exoplanet hunters have had an eye on Alpha Centauri, the closest star system to Earth at just four light-years away, for decades. We know that it consists of two Sun-like stars, Alpha Centauri A and ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

Is there a massive undiscovered planet on the outer reaches of the solar system? The idea has been around since before the discovery of Pluto in the 1930s. Labeled as planet X, prominent astronomers ...
