    Arecibo Observatory, an ‘icon of Puerto Rican science,’ will be demolished

    The telescope, known for cameos in moves like Contact and for fast radio burst observations, was feared to be on the verge of collapse.

    Planets with many neighbors may be the best places to look for life

    Solar systems with many planets in circular orbits suggest a calm life-nurturing past, while single exoplanets with eccentric orbits hint at chaos.

    The Milky Way makes little galaxies bloom, then snuffs them out

    When dwarf galaxies cross the Milky Way’s frontier, our galaxy compresses their gas, sparking star birth, but then robs them of their star-making gas.

    The asteroid Bennu’s brittle boulders may make grabbing a sample easier

    NASA’s OSIRIS-REx spacecraft is about to collect a bit of asteroid Bennu. Here’s why it’s good that new research suggests its boulders are brittle.

    The Milky Way’s most massive star cluster may have eaten a smaller cluster

    Observations of newfound stars suggest how the gathering of stars at the galaxy’s core grew so big.

    Stellar winds hint at how planetary nebulae get their stunning shapes

    Observations of red giant stars reveal that planets or even other stars may influence the shape of a nebula’s cloud of dust and gas.

    Neutrinos could reveal how fast radio bursts are launched

    Highly magnetized stellar corpses called magnetars may be the source of two different cosmic enigmas: fast radio bursts and high-energy neutrinos.
