A study led by the University of Oxford has identified a new type of planet beyond our solar system—one that stores large amounts of sulfur deep within a permanent ocean of magma. The findings have been published in Nature Astronomy. Go to Source We’re starting to see just how exceptional our own solar system and its history is, as more exoplanets are discovered. A fourth exoplanet discovery in the LHS 1903 system made by ESA’s CHEOPS mission places a rocky world right where it shouldn’t be. This “inside-out system” could challenge our current understanding of planetary formation. Go […] Using the Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new super-Earth exoplanet orbiting a star located about 83 light years away. The newfound alien world is slightly larger than Earth and encircles its host in less than four days. The finding was reported in a paper published Feb. 28 on the arXiv pre-print […] Astronomers have employed the Australia Telescope Compact Array (ATCA) to investigate a peculiar pulsar wind nebula known as Vela X. Results of the new observations, published March 2 on the arXiv pre-print server, provide more hints about the properties and nature of this nebula. Go to Source An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a complex planetary nebula known as NGC 6302. The observations, detailed in a paper published Feb. 25 on the arXiv pre-print server, resulted in the discovery of dry (carbon dioxide) ice in this nebula. This is the first time dry […] Dragonfly integration and testing—the activities involved in assembling the mission’s rotorcraft lander and testing it for the rigors of launch and extreme conditions of space—is officially underway in clean rooms and control rooms at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. Go to Source An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected gravitational waves from a binary black hole merger, designated S241125n. Remarkably, just seconds later, satellites recorded a short gamma-ray burst (GRB) from the same region of the sky. Go […] Astronomers have found an exoplanet that could serve as a benchmark in future studies. It’s a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a benchmark for understanding other M-dwarf exoplanets and their atmospheres. According to the authors of a new study, this new exoplanet could […] Cosmic rays are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the first time on European soil, an international research team in collaboration with the European Space Agency (ESA) has succeeded in providing a simulator for galactic cosmic rays at the GSI/FAIR accelerator facility in […] Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising trait: They are unusually calm and quiet in terms of harsh radiation. This tranquility is not just a cosmic curiosity; it may be essential for forming complex molecules that provide the ingredients of life. […] A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature Communications, the team uses machine learning and artificial intelligence to decipher the data from astrophysical observations to better understand how neutrons and protons interact […] NASA cleared its moon rocket on Thursday for an April launch with four astronauts after completing the latest round of repairs. Go to Source Two powerful instruments of the NASA/ESA/CSA James Webb Space Telescope joined forces to create this scenic galaxy view. This spiral galaxy is named NGC 5134, and it is located 65 million light-years away in the constellation Virgo. Though 65 million light-years may seem like a huge distance—the light that Webb collected to create this image […] Imagine looking up at the night sky and seeing a star suddenly burst into a blaze of light brighter than anything nearby. A flash so bright that it briefly outshines an entire galaxy before fading forever. Go to Source “Follow the water” has been a guiding mantra of astrobiology, and even space exploration more generally, for decades. If you want to find life, it makes sense to look for the universal solvent that almost all types of life on Earth use. But what if life doesn’t actually need water to live or even evolve? […] |
