Exoplanet Hunter Racks up 5,000 “Objects of Interest”

Since its 2018 launch, the unassuming TESS satellite has found 175 confirmed exoplanets (so far) among 5,000 “objects of interest.”

Concept of the universe's expansion

Cosmology

No Release for the Hubble Tension

New data and analysis show that a long-standing discrepancy in the measurement of the current expansion rate of the universe is real — even as the reason for it remains a mystery.
