The planet’s atmosphere explains the gravity of the situation. Venus, Earth’s sister planet, would likely not rotate, if not for its soupy, fast-moving atmosphere. Instead,…
Researchers of the University of Zurich (UZH) and the National Centre of Competence in Research (NCCR) PlanetS have investigated Jupiter’s formation history in great detail….
The Solar System has eight planets. In 2006, astronomers reclassified Pluto as a dwarf planet, the same class as contains Eris, Sedna, Quaoar, Ceres, and…
Earth’s supply of water is incredibly important for its ability to sustain life, but where did that water come from? Was it present when Earth…
A new study from the University of Warwick demonstrates the impact of passing stars, misaligned binary stars, and passing gas clouds on the formation of…
To understand how life emerged, scientists investigate the chemistry of carbon and water. In the case of water, they track the various forms, or isotopes,…
The James Webb Space Telescope (Webb) is designed to answer fundamental questions about the Universe. One of Webb’s key science goals is to study the…
Researchers find high-energy oxygen and sulfur ions in Jupiter’s inner radiation belts — and a previously unknown ion source. Nearly 20 years after the end…
By looking at the range of isotopic variations in terrestrial and meteoritic samples, a Lawrence Livermore National Laboratory (LLNL) scientist and collaborators have figured out…
International research team investigated the isotopic composition of rocky planets in the inner Solar System. Earth and Mars were formed from material that largely originated…
Meteorites are remnants of the building blocks that formed Earth and the other planets orbiting our Sun. Recent analysis of their isotopic makeup led by…
Stunning Yearly Observations Reveal Changes to Gas Giants’ Atmospheres In Greek mythology, a race of giants, called the Titans, first ruled the world. The ancient…
Wind the cosmic clock back a few billion years and our Solar System looked much different than it does today. About 4.5 billion years ago,…
A compositional link between planets and their respective host star has long been assumed in astronomy. For the first time now, a team of scientists,…
Scientists find evidence the early solar system harbored a gap between its inner and outer regions. The cosmic boundary, perhaps caused by a young Jupiter…
Giant gas planet orbiting a dead star gives glimpse into the predicted aftermath of our sun’s demise. Astronomers have discovered the very first confirmed planetary…
Set to launch next year, NASA’s Psyche mission marks the first time the agency has set out to explore an asteroid richer in metal than…
