When it comes to explaining how planets are formed, the protoplanetary hypothesis is the most widely accepted explanation. In simple terms, the donut-shaped disc of dust and gas around a star forms ...

Astronomers have discovered a giant Jupiter-like exoplanet in an unlikely location – orbiting a small red dwarf star. The newly identified gas giant, designated GJ 5312b, is nearly half as massive as ...

Two months ago, Dr. Hal Levison from the Southwest Research Institute (SwRI) in Boulder, Colorado, co-authored a paper that described a theory of “pebble formation” for gas giants. He has now expanded ...

Berkeley – Astrophysicists at the University of California, Berkeley, and Lawrence Livermore National Laboratory (LLNL) have exploded one of two competing theories about how stars form inside immense ...

In 2014, scientists found one of the key components of life out in the cosmos — an exoplanet with water vapor in its atmosphere. We now know that this was no anomaly. Most exoplanets likely have water ...

A recent study published in Science examines exoplanet LHS 3154b that orbits its parent star in just 3.7 days but is 13.2 times as massive as the Earth with the star being nine times less than our Sun ...

Astronomers are questioning the theories of planet formation after discovering an exoplanet that technically shouldn’t exist. The planet, about the mass of Neptune and more than 13 times as massive as ...

This story was updated at 5:15 p.m. EDT. Astronomers have found evidence of an alien planet forming surprisingly far from its host star, a discovery that could challenge the prevailing wisdom about ...

You’ve probably seen the analogy of the Earth’s timeline compared to a one day, 24-hour period. If not, take a look at the video below to get a quick understanding. According to this analogy, Earth ...

A pair of NASA spacecraft detected tiny variations in the Moon's gravitational pull, which may be the result of a dense layer sinking to the bottom. Reading time 2 minutes During its early years of ...
