A massive meteor struck near Manson, Iowa, 74 million years ago, creating the U.S.'s largest impact crater and reshaping the ...

When a full moon peeks just above the horizon, it appears enormous. This is a curious phenomenon, as when it is at this ...

M87* and Sag A*. The fact that we can capture such images is remarkable, but they might be the only black holes we can ...

Some 350 light-years away, the V1298 Tau system features an infant sun-like star, just 23 million years old, orbited by four ...

Nabil, W. (2026) Northward Geophysical Accretion Hypothesis (NGAH) of the Earth: A Hypothesis of Progressive Asymmetric ...

A decade of observations of four planets around the young planetary system V1298 Tau revealed a rare, long-sought missing ...

In this video, we derive the speed required for a stable circular orbit around Earth using Newton’s law of gravitation and centripetal force. You’ll see how orbital speed depends on radius, why low ...

Exoplanets like Earth have been discovered but not all Earth-like planets are equal when it comes to alien life.

Most planetary systems contain worlds larger than Earth but smaller than Neptune, and the low-density planets around one young star should help us understand how such systems form ...

At the start of the year, Earth will quietly reach a milestone in its orbit around the sun. Known as perihelion, this is the moment when our planet is closer to the sun than at any other point in the ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

Introduction: The identification of habitable exoplanets is an important challenge in modern space science, requiring the combination of planetary and stellar parameters to assess conditions that ...
