The Discovery A possible “super-Earth” orbits a relatively close, Sun-like star, and could be a habitable world – but one of extreme temperature swings, from scorching heat to deep freeze. Key Facts The newly confirmed planet is the outermost of three detected so far around a star called HD 20794, just 20 light-years from Earth. […]

The Flame Nebula, located about 1,400 light-years away from Earth, is a hotbed of star formation less than 1 million years old. Within the Flame Nebula, there are objects so small that their cores will never be able to fuse hydrogen like full-fledged stars—brown dwarfs. Brown dwarfs, often called “failed stars,” over time become very […]

Arp 105 is a dazzling ongoing merger between an elliptical galaxy and a spiral galaxy drawn together by gravity, characterized by a long, drawn out tidal tail of stars and gas more than 362,000 light-years long. The immense tail, which extends beyond this image from NASA’s Hubble Space Telescope, was pulled from the two galaxies […]

A tiny fraction of the stellar nursery known as Sh2-284 is visible in this glittering, star-filled NASA Hubble Space Telescope image. This immense region of gas and dust is the birthing place of stars, which shine among the clouds. Bright clusters of newborn stars glow pink in infrared light, and clouds of gas and dust, […]

An open cluster of stars shines through misty, cocoon-like gas clouds in this Hubble Space Telescope image of NGC 460. NGC 460 is located in a region of the Small Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. This particular region contains a number of young star clusters and nebulae of different sizes […]

Sweeping spiral arms extend from NGC 4536, littered with bright blue clusters of star formation and red clumps of hydrogen gas shining among dark lanes of dust. The galaxy’s shape may seem a little unusual, and that’s because it’s what’s known as an “intermediate galaxy”: not quite a barred spiral, but not exactly an unbarred […]

High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows extraordinary new detail and structure in Lynds 483 (L483). Two actively forming stars are responsible for the shimmering ejections of gas and dust that gleam in orange, blue, and purple in this representative color image.

An international team of researchers has discovered that previously observed variations in brightness of a free-floating planetary-mass object known as SIMP 0136 must be the result of a complex combination of atmospheric factors, and cannot be explained by clouds alone.
