Uranus and Neptune are the two furthest planets in the Solar System and have been visited only once by human spacecraft – by Voyager 2 over 30 years ago – so there is a lot about them that we do not know. One thing we thought we knew, however, was what type of planet they are. Now, a new study …

Astronomers have long called Uranus and Neptune the “ice giants” because models suggested that these outer planets’ interiors are largely made of mixtures of water, ammonia and other ices — compounds that freeze easily in deep space. But new research reveals that we actually know very little about what’s going on inside these planets, causing researchers to propose that Uranus …

What if our understanding of Uranus and Neptune’s compositions have been wrong, specifically regarding their classifications as “ice giants”? This is what a recent study accepted for publication in *Astronomy & Astrophysics* hopes to address as a team of researchers from the University of Zurich investigated the interior structures of Uranus and Neptune. This study has the potential to help …

Astronomers have launched a new program known as ATREIDES to study a mysterious “desert” in space. But unlike the deserts of the planet Arrakis conquered by Paul Atreides in the “Dune” novels by Frank Hebert, this desert describes an absence of planets with masses up to around 20 times the mass of Earth that orbit close to their stars, planets …

The Kuiper Belt is home to rocky, icy bodies left over from the formation of the solar system. Credit: ESO/M. Kornmesser, CC BY 4.0 It’s been nearly 2 centuries since a planet was discovered in the solar system. But now scientists think they’ve uncovered evidence of a newcomer that just might usurp that honor from Neptune. Following an analysis of the orbits …

In 2018 and 2019, Sanchez-Vidal’s team examined seagrass balls washed up on four beaches on the island of Mallorca, Spain. On the shores of Sa Marina, Son Serra de Marina, Costa dels Pins and Es Peregons Petits, they found plastic debris in half of the loose seagrass leaf samples, up to 600 fragments per kilogram (2.2lb) of leaves. Only 17% …

IN A NUTSHELL 🔭 Astronomers have identified a potential candidate for the elusive Planet Nine beyond Neptune. 🛰️ The discovery was made using archival data from the IRAS and AKARI satellites. ❓ There is significant skepticism due to the candidate’s orbit not aligning with Planet Nine predictions. 🔍 The Vera C. Rubin Observatory could provide definitive evidence to confirm or …

For centuries, humans have gazed into the night sky, wondering what lies beyond the planets we know. Each new discovery in the Solar System reshapes our sense of place in the cosmos. Now, astronomers are once again pointing to the possibility of an unseen world – one that may be orbiting far beyond Neptune. This hypothetical body has been given …
