Four takeaways from astronomer Cullen Blake on what this potentially groundbreaking study shows and what comes next for scientists who are keen to understand these faraway chemical signals.
Finding this new stellar stream, named after Nyx, the Greek goddess of night, was made possible using machine learning tools and simulations of data collected by the Gaia space observatory.
Observations by the Atacama Cosmology Telescope suggest that the universe is 13.77 billion years old, and reveals how fast the cosmos is expanding.
As research on campus slowly restarts, those whose work requires field surveys, large-scale collaborations, or travel face additional challenges in bringing their research back online.
This updated catalog of trans-Neptunian objects and the methods used to find them could aid in future searches for undiscovered planets in the far reaches of the solar system.
A state-of-the-art instrument called NEID, from the Tohono O’odham word meaning “to see,” collected its “first light” and is poised to look for new planets outside the solar system.
Researchers find a link between the masses of supermassive black holes and the distances between the galaxies which surround them, allowing astronomers to more easily study many astronomical phenomena.
Key facts and figures about the unseen matter that remains one of cosmology’s greatest unsolved mysteries.
Penn astronomers are part of an international collaboration to construct the Simons Observatory, a new telescope that will search the skies in a quest to learn more about the formation of the universe.
As the nation celebrates the Apollo 11 mission, a look at Penn’s connection to the historic event and how the Moon impacts science, politics, and culture.

The School of Arts and Sciences’ Cullen Blake weighed in on the identification of an earth-like exoplanet called Barnard’s Star b. Blake said that while the data used to locate it may be muddied by nearby stellar activity, the exoplanet has been observed enough times to be a strong planetary candidate.
