All Stories by Lisa Grossman

  1. An illustration of the Milky Way with two bubbles shown in blue and purple coming from the center of the galaxy.

    Cosmic antimatter hints at origins of huge bubbles in our galaxy’s center

    An excess of positrons in Earth’s vicinity supports the idea that the Fermi bubbles were burped by the Milky Way’s supermassive black hole long ago.

  2. A telescope image of a long stream of cold cosmic gas seen as a blue line coming off a big purple circle on a dark background.

    A stream of cold gas is unexpectedly feeding the far-off Anthill Galaxy

    The finding suggests that early galaxies might have gained more of their bulk from streams of cold gas instead of in violent galaxy collisions.

  3. illustration of two merging neutron stars in blue

    A neutron star collision may have emitted a fast radio burst

    Astronomers spotted both a fast radio burst and gravitational waves from a cosmic smashup in the same part of the sky and at about the same time.

  4. An astronaut in a space suit stands with their back to the camera and looks out at inflatable domes as part of a habitat on Mars.

    ‘Off-Earth’ asks how to build a better future in space

    As humans prepare to live in space someday, ethics should be as much of guide as science and technology, an astrophysicist argues in a new book.

  5. An image of Maat Mons on Venus based on data from spacecraft. A yellow mountain rises up on a black background with a brown area in the foreground.
    Planetary Science

    A volcano on Venus was spotted erupting in decades-old images

    A new look at old data reveals an eruption on Venus in the 1990s that was probably similar to Hawaii’s Kilauea eruption in 2018.

  6. An illustration of a black hole.

    A runaway black hole has been spotted fleeing a distant galaxy

    A bright streak stretching away from a remote galaxy might be the light from stolen gas and new stars caught in the wake of an escaping black hole.

  7. An image from the James Webb Space Telecope showing face-on spiral galaxy, NGC 628, with its whorls of colored gas and dust, pockmarked with dark areas.

    Newborn stars sculpt their galaxies in new James Webb telescope images

    Dark voids riddle the galaxies’ faces, highlighting previously invisible details about how new stars alter their locales.

  8. A view of the Earth from space with several white dots, representing Starlink satellites, forming a ring around it.

    Half of all active satellites are now from SpaceX. Here’s why that may be a problem

    Of the roughly 7,300 active satellites in Earth orbit, about 3,600 are part of SpaceX’s growing fleet of Starlink internet satellites.

  9. Six images from the James Webb Space Telescope with three on top and three on the bottom. Each shows a different bright, red, dot that is a galaxy.

    The James Webb telescope found six galaxies that may be too hefty for their age

    The galaxies formed in the universe’s first 700 million years and may be up to 100 times more massive than predicted.

  10. An illustration of the James Webb Space Telescope deployed in space.

    The James Webb telescope spotted the earliest known ‘quenched’ galaxy

    A galaxy dubbed GS-9209 ceased forming stars more than 12.5 billion years ago after a 200-million-year-long sprint.

  11. An illustration of the dwarf planet Quaoar.

    The Kuiper Belt’s dwarf planet Quaoar hosts an impossible ring

    Quaoar’s ring lies outside the Roche limit, an imaginary line beyond which rings aren’t thought to be stable.

  12. aerial photo of San Francisco at night

    New data show how quickly light pollution is obscuring the night sky

    Tens of thousands of observations from citizen scientists spanning a decade show that the night sky is getting about 10 percent brighter every year.
