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 Carnegie's Nicole Nie and published in Science Advances settles a longstanding debate about the geochemical evolution of our Solar System and our home planet. In their youth, stars are surrounded by a rotating disk of gas and dust. Over ti

The nature of free-floating planets (FFPs) is still mysterious. FFPs might originate in two ways: they either form on their own, like stars, through the gravitational collapse of small clouds of gas, or they form like planets around stars and then get stripped off from their stellar systems. Until now it was hard to investigate which formation mechanism is more likely, as a large homogenous samp

An international team of astronomers used data from the Hubble Space Telescope to discover the signature of a magnetic field in a planet outside our solar system. The finding, described in a paper in the journal Nature Astronomy, marks the first time such a feature has been seen on an exoplanet. A magnetic field best explains the observations of an extended region of charged carbon particl

"We did not know how many to expect and are excited to have found so many," says Nuria Miret-Roig, an astronomer at the Laboratoire d'Astrophysique de Bordeaux, France and the University of Vienna, Austria, and the first author of the new study published in Nature Astronomy. Rogue planets, lurking far away from any star illuminating them, would normally be impossible to image. However, Mir

In Lovecraftian horror, the Universe is filled with "dark planets" ungraced by the light of a host star. New research shows that reality might be even scarier. An international team composed of French, Japanese, and Spanish astronomers has found about 100 planets floating freely in space rather than orbiting stars. Extrapolating this sample to the rest of the Milky Way Galaxy suggests that there

Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit. A group of researchers led by the University of Munster (Germany) report these findings in the journal "Science Advances". They present the most comprehensive comparison to date of the isotopic composit

When NASA's Volatiles Investigating Polar Exploration Rover, or VIPER, explores and samples the soils at the Moon's South Pole, scientists anticipate it will reveal answers to some of the Moon's enduring mysteries. Where is the water and how much is there? Where did the Moon's water come from? What other resources are there? What other questions could VIPER answer? NASA sought ideas and re

Virgin Orbit, the responsive launch and space solutions company that has announced a planned business combination with NextGen Acquisition Corp. II, has signed a new launch contract covering two dedicated launches for Arqit Quantum, Inc. a global leader in quantum encryption technology, plus additional commitments. The two Arqit satellites delivered to Earth orbit by Virgin Orbit's Launche

NASA and Boeing crews have successfully placed the forward skirt for NASA's Space Launch System (SLS) Artemis III rocket into the Vertical Assembly Center robotic weld tool for its next phase of production at NASA's Michoud Assembly Facility in New Orleans. The forward skirt sits atop the rocket's core stage, and it will be outfitted with the rocket's flight computers and avionics systems

The International Space Station Archaeological Project is the first archaeological study of a human habitat in space. Because of the prohibitive cost of travelling to space, archaeologists have had to think of creative ways to investigate the material culture of the space station. One method is to analyze the thousands of photographs taken of the space station's interior. Authors Dr. Justi
