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.
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.
Astronomers have reclassified Terzan 5, long catalogued as a globular cluster, as a surviving remnant from the Milky Way's formation - a 'bulge fossil fragment' with four distinct stellar generations spanning billions of years.
A study published in Nature Astronomy on June 10, 2026 uses JWST's NIRSpec to directly detect that the morning and evening terminator regions of the tidally locked gas giant have measurably different temperatures and chemical composition.
New JWST observations of NGC 4696 have traced, for the first time, how galaxy-spanning filaments of cooling gas connect to a rotating circumnuclear disk that funnels material toward a supermassive black hole - closing a long-standing gap in black hole physics.
