Jupiter's moon Callisto is very likely an ocean world

More pocked with craters than any other object in our solar system, Jupiter's outermost and second-biggest Galilean moon, Callisto, appears geologically unremarkable. In the 1990s, however, NASA's Galileo spacecraft captured ...

Mission accomplished for space telescope Gaia

The space telescope Gaia has created the largest three-dimensional map of the Milky Way ever. On January 15, 2025, Gaia shut down after 11 years in space. But the research on data Gaia collected will continue for many years ...

Why we think Theia existed

The giant-impact hypothesis posits that billions of years ago a Mars-sized body named Theia collided with the early Earth.

A new theory explains how water first arrived on Earth

When Earth first formed, it was too hot to retain ice. This means all the water on our planet must have originated from extraterrestrial sources. Studies of ancient terrestrial rocks suggest liquid water existed on Earth ...

Many stars could have sent us 'Oumuamua

When astronomers detected the first known interstellar object, 'Oumuamua, in 2017, it sparked a host of new studies trying to understand the origin and trajectory of the galactic sojourner.

Why the first stars couldn't grow forever

Star formation in the early universe was a vigorous process that created gigantic stars. Called Population III stars, these giants were massive, extremely luminous stars that lived short lives, many of which ended when they ...

Kitchen experiments shed light on Mars's volcanic rootless cones

Rootless cones are small volcanic landforms ranging from several to several hundred meters in diameter, formed by continuous explosions resulting from the interaction between surface lava and water bodies like lakes and rivers. ...

There's more than just gravity at work in the solar system

Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's responsible for the orbits of the planets and their satellites, but there are other forces that ...

Ingenuity measurements reveal surprising wind speeds on Mars

One of my gripes with "The Martian" movie was the depiction of the winds on Mars. The lower air density means that the sort of high speed winds we might experience on Earth carry far less of an impact on Mars. During its ...

Hubble studies the Tarantula Nebula's outskirts

This NASA/ESA Hubble Space Telescope image features a dusty yet sparkling scene from one of the Milky Way's satellite galaxies, the Large Magellanic Cloud. The Large Magellanic Cloud is a dwarf galaxy situated about 160,000 ...

Fast radio bursts appear to be caused by young neutron stars

Fast radio bursts (FRBs) are one of the greater mysteries facing astronomers today, rivaled only by gravitational waves (GWs) and gamma-ray bursts (GRBs). Originally discovered in 2007 by American astronomer Duncan Lorimer ...
