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 ...
Scientists have made a new discovery on how small planets might form. Researchers at the University of Warwick investigated the "birth environment" of planets—areas of gas and dust that swirl around a central star—known as ...
Wake up early this weekend to catch a celestial sight: Five planets will line up in the sky before sunrise on Saturday.
