The Fornax Dwarf is a dwarf spheroidal galaxy and satellite of the Milky Way discovered by Harlow Shapley in 1938. Located about 450,000 light-years away, it’s unusual in possessing a large number of globular clusters — six in all. Four are visible in 8-inch and 10-inch telescopes.ESO / Digitized Sky Survey Road trip! Dark-sky die-hards […]
A recent cosmic census has revealed an unexpected threefold rise in active black holes within dwarf galaxies, creating the most extensive database of intermediate-mass black holes recorded to date. This survey, conducted with the Dark Energy Spectroscopic Instrument (DESI) at the Mayall Telescope in Arizona, identified over 2,500 black holes in dwarf galaxies—more than triple […]

A 1995 Hubble Space Telescope image of the brown dwarf Gliese 229 B next to its far brighter host star, the M dwarf Gliese 229 A. S. Kulkarni (Caltech), D.Golimowski (JHU) and NASA Astronomers recently discovered a companion to Gliese 229 B, the first confidently identified brown dwarf. This discovery resolves the conflict between Gliese […]
A celestial body found three decades ago has now been identified as a pair of brown dwarfs orbiting each other, a recent study has revealed. The object, previously known as Gliese 229B, was the first brown dwarf discovered 30 years ago. Brown dwarfs are considered too large to be planets yet too small to ignite […]

Risinger/Handout via REUTERS By Will Dunham WASHINGTON (Reuters) – In 1995, astronomers confirmed the discovery for the first time of a brown dwarf, a body too small to be a star and too big to be a planet – sort of a celestial […]
Congratulations, it’s twins K. Miller, R. Hurt/Caltech/IPAC An odd star that has confused researchers for decades now makes sense – it turns out not to be a single star but two companions. “It used to be that this brown dwarf didn’t make any sense. We worried that we were doing something horribly wrong, or that […]
