A new landmark study has pinpointed the location of the universe’s “missing” matter, and detected the most distant fast radio burst (FRB) on record...

An international team of astronomers including researchers at the University of Arizona Lunar and Planetary Laboratory has unveiled groundbreaking findings about the disks of gas and dust surrounding nearby young stars, using the powerful Atacama Large Millimeter/submillimeter Array, or ALMA.

The findings, published in 12 papers in a focus issue of the Astrophysical Journal, are part of an ALMA large program called the ALMA Survey of Gas Evolution of PROtoplanetary Disks, or AGE-PRO...

Scientists have discovered a giant planet orbiting a tiny red dwarf star, something they believed wasn’t even possible. The planet, TOI-6894b, is about the size of Saturn but orbits a star just a fifth the mass of our Sun. This challenges long-standing ideas about how big planets form, especially around small stars. Current theories can’t fully explain how such a planet could have taken shape. Even more fascinating, this cold planet may have a rare kind of atmosphere rich in methane or even ammonia something we’ve never seen in an exoplanet before.

Small telescopes in Chile are first on Earth to cut through the cosmic noise. For the first time, scientists have used Earth-based telescopes to look back over 13 billion years to see how the first stars in the universe affect light emitted from the Big Bang.

Using telescopes high in the Andes mountains of northern Chile, astrophysicists have measured this polarized microwave light to create a clearer picture of one of the least understood epochs in the history of the universe, the Cosmic Dawn.

“People thought this couldn’t be done from the ground. Astronomy is a technology-limited field, and microwave signals from the Cosmic Dawn are famously difficult to measure,” said Tobias Marriage, project leader and a Johns Hopkins professor of physics and astronomy...
