Named MoM-BH*-1, it shines like 100 billion Suns yet carries the light signature of a single star. MIT researchers say the best explanation is a black hole cloaked in a solar-system-sized shell of hydrogen - and that Webb's 'little red dots' may be the same thing.
A new survey of 31 ancient quasars includes two all-time record-breakers that shone 13 billion years ago. Euclid did in a year what took all prior telescopes over a decade.
NASA's James Webb Space Telescope has found that galaxy cluster XLSSC 122, from 10.4 billion years ago, is the most distant known strong gravitational lens - with a dark matter core so concentrated that the standard Lambda CDM cosmological model cannot account for it.
A peer-reviewed rebuttal co-authored by Nobel laureates Adam Riess and Brian Schmidt found two methodological mistakes in a high-profile 2025 study that claimed cosmic acceleration might be an illusion - and concluded the universe is still accelerating.
