Supernova simulations show that low-mass star in binary system J0453+1559 could be a neutron star

In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly magnetized rapidly rotating, light-emitting neutron star) and a so-called companion star. The companion ...

Webb reveals unexpected complex chemistry in primordial galaxy

University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was just less than 300 million years old—just 2% of its current age.

Astrophysicists predict origins of unexpected space objects in solar system and Alpha Centauri

Interstellar material has been discovered in our solar system, but researchers continue to hunt for where it came from and how it got here. A new study led by Western astrophysicists Cole Gregg and Paul Wiegert recommends ...

Advanced imaging and theoretical physics unlock clues to new treatments for muscular dystrophy

A new discovery about how tiny protein clusters form in cells could pave the way for treatments for Emery-Dreifuss muscular dystrophy (EDMD), a rare genetic disorder that causes muscle weakness and heart problems.

Astronomer finds gas giant exoplanets formed earlier than previously thought

A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research. The Ohio State University study's results provide new information about ...

Gemini South observes ultra-hot nova erupting with surprising chemical signature

Nova explosions occur in binary star systems in which a white dwarf—the dense remnant of a dead star—continually siphons stellar material from a nearby companion star. As the outer atmosphere of the companion gathers ...

Lunar sample research could help protect astronauts and uncover origins of water on the moon

Dust and rocks residing on the surface of the moon take a beating in space. Without a protective magnetosphere and atmosphere like Earth's, the lunar surface faces continual particle bombardment from solar wind, cosmic rays, ...

Neural network deciphers gravitational waves from merging neutron stars in a second

Binary neutron star mergers occur millions of light-years away from Earth. Interpreting the gravitational waves they produce presents a major challenge for traditional data-analysis methods. These signals correspond to minutes ...

Eccentricities of orbits point to significantly different upbringings for small and large planets

The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have ...
