In 2015, NASA celebrated the Hubble Space Telescope’s 25th year in orbit by releasing one of its most stunning images to date—a colorful star cluster in the constellation Cari ...

Hubble spots white dwarf star 'snacking' on chunk of Pluto-like object. The NASA/ESA Hubble Space Telescope has spotted a ...

Astronomers using the James Webb Space Telescope (JWST) report finding silane – a silicon-hydrogen molecule – in a brown dwarf called the Accident. That simple molecule points to a long-missing piece ...

Figure1: Infrared image showing the directly imaged brown dwarf companion J1446B (dot indicated by the arrow). The central red dwarf (J1446) is masked in white during image processing. The scale bar ...

When astronomers pointed the James Webb Space Telescope (JWST) at a faint object orbiting a distant star system, they weren’t expecting to find one of the universe’s strangest chemical ...

An illustration of the Wolf 1130ABC triple system, which is composed of a red dwarf star (left), a white dwarf (center) and the brown dwarf where phosphine was detected (right). Adam Burgasser For the ...

Brown dwarfs: too small to be stars, too big to be planets. Only discovered in the 1990s, these in-between cosmic objects aren’t big enough to burn as hot and bright as a true star, instead usually ...

An orange, striated sphere hangs in space with stars behind it with a line from it drawn to a box that contains a space-filling model of phosphine where phosphorus is orange and hydrogen is white.

The detection of the molecule phosphine in a brown dwarf’s atmosphere may help astronomers in their search for life elsewhere in the Milky Way. By Katrina Miller On a brown dwarf dozens of light years ...

Schematic of the Wolf 1130ABC triple system, composed of the red dwarf star Wolf 1130A (l), its close and compact white dwarf companion Wolf 1130B (c), and the distant brown dwarf tertiary Wolf 1130C ...

Red dwarf stars make up the largest population of stars in the galaxy, but they hide in the shadows, too dim to be seen with the naked eye from Earth. Their limited radiance helps to extend their ...
