Artemis II to test new models that predict solar particle storms up to a day ahead
During the Artemis II mission launched Wednesday, NASA will test out a pair of new solar radiation forecasts, developed at University of Michigan Engineering, designed to protect astronauts venturing away from Earth. The forecasts will provide warnings of harmful solar radiation released by solar flares and eruptions up to 24 hours in advance. NASA’s Space Radiation Analysis Group (SRAG) is examining how new solar particle forecasting technologies might provide a faster response to changing space weather conditions during the Artemis missions, which will mostly fly outside the natural shielding provided by Earth’s magnetic field.
Early data from Vera C. Rubin Observatory reveals over 11,000 new asteroids
Using preliminary data from the Vera C. Rubin Observatory, scientists have discovered over 11,000 new asteroids. The data were confirmed by the International Astronomical Union’s Minor Planet Center (MPC), making this the largest single batch of asteroid discoveries submitted in the past year. The discoveries were made using data from Rubin’s early optimization surveys and offer a powerful preview of the observatory’s transformative impact on solar system science.
‘Serendipitous’ discovery of Martian ripple marks reveals an ancient sandstorm
The search for life on Mars involves the efforts of scientists from many different disciplines. An important aspect of that search is to study Martian sedimentary rocks for information about the planet’s environment when it is likely that the surface environment hosted abundant water and therefore more habitable, around three to four billion years ago. Now, research published in the journal Geology shows evidence of an intense sandstorm that swept through Mars’s Gale crater over three billion years ago.
Giant ‘forbidden planet’ orbiting small star shows an unusually low-metal atmosphere
Scientists have discovered that a highly unusual giant planet—sometimes called “forbidden”—could have an atmosphere with fewer heavier elements than its host star. University of Birmingham astrophysicist Dr. Anjali Piette worked with an international research team to analyze James Webb Space Telescope data from the exoplanet TOI-5205 b. This is a Jupiter-sized planet orbiting a star about four times the size of Jupiter and about 40% the mass of the sun.

AI system can predict seasonal droughts
Researchers at the Institute of Water and Environmental Engineering (IIAMA) at the Universitat Politècnica de València have developed an advanced system for seasonal forecasting of meteorological droughts that enables these events to be predicted up to six months in advance, providing a key tool for water management and early warning in semi-arid regions, such as the Júcar river basin.
Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims
Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles are enough: causality, the fact that no signal can travel faster than light, and unitarity, the requirement that probabilities are conserved in quantum mechanics. The structure of supergravity is not assumed: it bootstraps itself.

Study suggests people are losing 338 spoken words every year and have been for at least 15 years
In a society increasingly shaped by self-checkouts, GPS navigation and touchscreen ordering kiosks, new research shows face-to-face conversation may be quietly fading. A new study published in Perspectives on Psychological Science suggests that people are losing 338 spoken words every year and have been for at least a decade and a half.
Gravitational waves suggest a ‘forbidden zone’ for stellar-origin black holes
An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive stars collapse into black holes—objects with gravity so strong that not even light can escape.
Q&A: What to know about NASA’s first crewed moon landing since 1972
Artemis II, NASA’s first crewed mission to the moon in more than 50 years, represents a shift from short visits toward sustained exploration, where understanding lunar geology and resources becomes as important as the engineering that gets astronauts there. Artemis II is currently scheduled to launch Wednesday, April 1, at 6:24 p.m. EDT, with backup launch opportunities through early April if needed.

High nickel concentrations in Martian bedrock point to potential biosignatures
In 2024, NASA’s Perseverance rover found surprising levels of Nickel in the Martian bedrock of an ancient river channel, called Neretva Vallis, which flowed into the Jezero crater. A new study, published in Nature Communications, has taken a closer look at the data collected from the region and researchers are seeing what could be remnants of ancient Martian life.
