Two new research projects will bring advanced tools to Lick and McDonald Observatories, studying planet and star formation. The programs aim to extend the scientific reach of mid-sized telescopes, delivering new insights and demonstrating technologies for larger observatories.
Researchers used a new method to precisely locate a fast radio burst, finding it in the outskirts of an old elliptical galaxy. This discovery raises questions about how energetic events occur in regions without new star formation, and challenges existing theories about FRB origins.
A new study using the James Webb Space Telescope has reevaluated the atmospheric composition of Trappist-1 b, finding conditions that could support a thick CO2-rich atmosphere. Researchers propose that haze from hydrocarbon compounds in the upper atmosphere may explain this scenario.

Astronomers have imaged the coldest exoplanet ever detected using JWST, which agrees with models of planet evolution and solar system ages. The exoplanet orbits a super-Jupiter in the Epsilon Indi triple star system and has a mass six times that of Jupiter.
Four transiting short-period mini-Neptunes orbiting red dwarfs have been discovered, with radii 2-3 times that of Earth and orbital periods under eight days. Their interiors likely contain volatiles and atmospheres, suggesting non-rocky composition.
Researchers have identified a population of massive stars stripped of their hydrogen envelopes by their companions in binary systems. These hot helium stars are believed to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers, shedding new light on a long-theorized phenomenon.
Researchers using JWST's First Deep Field image identified the most distant globular clusters, potentially relics of the first and oldest stars. These discoveries provide a detailed look at the earliest phase of star formation, confirming JWST's power in uncovering the universe's origins.
