The standard model of the universe relies on just six numbers. Using a new approach powered by artificial intelligence, researchers at the Flatiron Institute and their colleagues extracted information hidden in the distribution of galaxies to estimate the values of five of these so-called cosmological parameters with incredible precision.

A new study published in The Astrophysical Journal, led by Assistant Professor of Astronomy Rana Ezzeddine and UF alumnus Jeremy Kowkabany, with collaborators, reports the discovery of a star that challenges astronomers’ understanding of star evolution and formation of chemical elements, and could suggest a new stage in their growth cycle.
It is widely accepted that as stars burn, they lose lighter elements like lithium in exchange for heavier elements like carbon and oxygen, but an analysis of this new star revealed that not only was its lithium content high for its age, but was higher than the normal level for any star at any age.
This star, named J0524-0336 based on its coordinates in space, was discovered recently by Ezzeddine as part of a different study that used surveying to look for older stars in the Milky Way. It is an evolved star, meaning that it is in the later stages of its “life” and is beginning to grow unstable. That also means that it is much larger and brighter than most other stars of its type, estimated to be about 30 times the size of the sun.
A new set of NASA science experiments and technology demonstrations will arrive at the lunar South Pole in 2027 following the agency’s latest CLPS (Commercial Lunar Payload Services) initiative delivery award. Intuitive Machines of Houston will receive $116.9 million to deliver six NASA payloads to a part of the Moon where nighttime temperatures are frigid, the terrain is rugged, and the permanently shadowed regions could help reveal the origin of water throughout our solar system.
Part of the agency’s broader Artemis campaign, CLPS aims to conduct science on the Moon for the benefit of all, including experiments and demos that support missions with crew on the lunar surface.
“This marks the 10th CLPS delivery NASA has awarded, and the fourth planned for delivery to the South Pole of the Moon,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “By supporting a robust cadence of CLPS flights to a variety of locations on the lunar surface, including two flights currently planned by companies for later this year, NASA will explore more of the Moon than ever before.”
The JUICE spacecraft recently swung past the Moon and Earth in a rare maneuver on its journey to Jupiter.
Researchers have engineered a new technique to trap ions in 3D structures using modified electric fields in Penning traps, forming stable bilayer crystals.
This innovation paves the way for more complex quantum devices and could revolutionize quantum computing and sensing by utilizing space more efficiently.
Quantum Device Challenges
A University of Maryland-led study reveals new details about asteroid dynamics following NASA ’s DART mission, which intentionally collided with the asteroid moon Dimorphos in 2022. The impact significantly altered Dimorphos’ trajectory and shape, leading to unexpected gravitational behaviors. These findings challenge previous assumptions about asteroid evolution and could influence future planetary defense strategies and space missions, as researchers continue to assess the system’s stability and potential for further exploration.
When NASA’s Double Asteroid Redirection Test (DART) spacecraft collided with an asteroid moon called Dimorphos in 2022, the moon was significantly deformed—creating a large crater and reshaping it so dramatically that the moon derailed from its original evolutionary progression—according to a new study. The study’s researchers believe that Dimorphos may start to “tumble” chaotically in its attempts to move back into gravitational equilibrium with its parent asteroid named Didymos.
“For the most part, our original pre-impact predictions about how DART would change the way Didymos and its moon move in space were correct,” said Derek Richardson, a professor of astronomy at the University of Maryland and a DART investigation working group lead. “But there are some unexpected findings that help provide a better picture of how asteroids and other small bodies form and evolve over time.”
Using observations from a NASA suborbital rocket, an international team of scientists, for the first time, has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields.
“There are many open clusters in the galaxy. However, not all open clusters have the same level of interest to astronomers,” Ignacio Negueruela, a researcher at the Universidad de Alicante who was part of the team behind the discovery of supergiants in Barbá 2, told Space.com. “Clusters rich in red supergiants are very rare and tend to be very far away, but they play a crucial role in understanding key aspects in the evolution of massive stars.”
The intimidating size and power of supergiants means these monster stars burn through their nuclear fuel much faster than stars like the sun. Whereas our star will exist in its main sequence lifetime for around 10 billion years, supergiants are estimated to last just a few million years.
The short lifetime of supergiants means that while open clusters like Barbá 2 are common, with over 1,100 already discovered in the Milky Way alone, finding one packed with red supergiants is extremely rare.
