Earth’s Water Was Around Before Planet Earth
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…
Nearby star-forming region yields clues to the formation of our solar system. The radioactive elements could have been blown onto the nascent solar system by…
There are eight known planets in the solar system (ever since Pluto was booted from the club), but for a while, there has been some…
The Sun releases a constant stream of particles and magnetic fields called the solar wind. This solar wind slams worlds across the solar system with…
Researchers use unusual meteorite to gain insight into our solar system’s past, present. In 2011, scientists confirmed a suspicion: There was a split in the…
A new study by a Belgian team using data from the European Southern Observatory’s Very Large Telescope (ESO’s VLT) has shown that iron and nickel…
As the solar system was developing, the giant planets (Jupiter and Saturn) formed very early, and as they grew, they migrated both closer to and…
