The ESA launched Gaia in 2013 with one overarching goal: to map more than one billion stars in the Milky Way. Its vast collection of data is frequently used in published research. Gaia is an ambitious mission, though it seldom ...
Saturn is best known for two things: its iconic ring structures and its large system of natural satellites. Currently, 146 moons and moonlets have been discovered orbiting the ringed giant, 24 of which are regular satellites. ...
A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash.
The New Horizons spacecraft that studied Pluto and Kuiper belt object Arrokoth continues its pioneering exploration of the Kuiper belt. However, that might soon end if NASA doesn't change course. The New Horizons science ...
Caroline Herschel, the first professional female astronomer, made contributions to astronomy that are still important to the field today. But even many astronomers may not recognize her name.
At the center of Earth is a vast ball of metal, the planet's core. While unreachable without the help of Jules Verne, it can be studied and plays a vital role for the world.
Physicists have identified a mechanism for the formation of oscillating superconductivity known as pair-density waves. Physical Review Letters published the discovery, which provides new insight into an unconventional, high-temperature ...
NASA has succeeded in re-establishing full contact with Voyager 2 by using its highest-power transmitter to send an "interstellar shout" that righted the distant probe's antenna orientation, the space agency said Friday.
At one time, astronomers believed that the planets formed in their current orbits, which remained stable over time. But more recent observations, theory, and calculations have shown that planetary systems are subject to shake-ups ...
Icy planets, such as Uranus (U) and Neptune (N), are found in both our solar system and other solar systems across the universe. Nonetheless, these planets, characterized by a thick atmosphere and a mantle made of volatile ...
