The path of a light beam is bent by the presence of mass, as explained by General Relativity. A massive body can therefore act like a lens—a so called "gravitational lens"—to distort the image of an object seen behind ...

An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a ...
A team of astronomers from Carnegie and the University of Western Ontario has discovered one of the youngest and brightest free-floating, planet-like objects within relatively close proximity to the Sun. The paper reporting ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new massive brown dwarf. The newfound object is nearly 80 times more massive than Jupiter and orbits an M-dwarf star known as TOI-5375. ...
Chromium hydride (CrH), a molecule that's relatively rare and particularly sensitive to temperature, is useful as a "thermometer for stars," according to astronomer Laura Flagg, because it's abundant only in a narrow range ...

Brown dwarfs are the middle child of astronomy, too big to be a planet yet not big enough to be a star. Like their stellar siblings, these objects form from the gravitational collapse of gas and dust. But rather than condensing ...

Brown dwarfs fill the "gap" between stars and the much smaller planets—two very different types of astronomical objects. But how they originate has yet to be fully explained. Astronomers from Heidelberg University may now ...
