Exoplanet Hunters Dim the Lights

Scientists have devised a new way to dim starlight's blinding glare, a technique that improves on existing technologies to allow astronomers a clearer view of exoplanets orbiting nearby stars.

Cosmology

Dark-Matter Thread Revealed

Scientists have found a dark-matter filament, a strand of the cosmic web that connects clusters of galaxies. It's the first time an individual filament has been detected and is among our first observational glimpses of the universe’s largest structures.

Seeing Exoplanets in a New Light

Researchers have devised a way to peek at the atmospheres of non-transiting exoplanets. The method may prove to be a valuable tool in astronomers' efforts to characterize planets outside our solar system.

Little Scope Makes Big Finds

Scientists using the diminutive KELT North telescope have discovered two extrasolar planets, one of which is unlike anything yet seen. The finding provides researchers with raw material to study exoplanets, but it also demonstrates that sometimes, the little guys can still win big.

Small Planets’ Evolutionary Edge

The discovery that planets can form around a variety of stars — and not just specific types, as previously thought — might open the floodgates on the search for habitable worlds in the galaxy.

Failed Stars Oddly Rare

Astronomers hunting for brown dwarfs in our solar neighborhood have been thrown a surprise: these star wannabes are far less common than previously thought.
