  1. Spitzer galaxy image
    Space

    As NASA’s Spitzer telescope’s mission ends, here’s a look back at its discoveries

    For more than 16 years, the Spitzer Space Telescope has witnessed the births and deaths of stars, charted the Milky Way, found faraway worlds and more.

  2. Asteroid 2020 AV2
    Planetary Science

    For the first time, an asteroid has been found nearer to the sun than Venus

    A space rock dubbed 2020 AV2, found in close orbit around the sun, probably got there after a series of close encounters with rocky planets.

  3. Proxima Centauri illustration

    A second planet may orbit Proxima Centauri

    The star closest to the sun may harbor another planet, this one much more massive and colder than Earth.

  4. Milky Way gas
    Space

    A giant wave of gas lurks near our solar system

    The Earth and sun are relatively near a newfound, wavy rope of star-forming gas, named the Radcliffe Wave.

  5. Milky way star cluster
    Space

    Young stars have been found in an old part of our galaxy

    A newly discovered star cluster in the Milky Way’s halo seems to have been deposited there by gas torn off of two satellite galaxies.

  6. ionized hydrogen bubbles
    Space

    Bubble-blowing galaxies could help solve a cosmic mystery

    Three galaxies ionizing hydrogen 680 million years after the Big Bang show a potential step in the ionization of nearly all hydrogen in the cosmos.

  7. Astronomy

    LIGO detects its second neutron star collision, but gains few clues

    Gravitational waves have once again heralded a smashup between neutron stars, but this time with no flash of light to help guide understanding.

  8. pulsar map
    Space

    The first glimpses of a pulsar’s surface hint at complex magnetism

    Maps of a rapidly spinning neutron star could eventually help researchers figure out how matter behaves at extraordinarily high densities.

  9. Southern Hemisphere
    Space

    A new map reveals radio waves from tens of thousands of galaxies

    Radio waves from about 17,000 galaxies show that the peak of star formation, about 10 billion years ago, might have been more productive than predicted.

  10. CHEOPS satellite illustration
    Space

    A new mission to investigate exoplanets has rocketed into space

    The European Space Agency’s CHEOPS satellite has launched on a mission to gather intel on previously discovered planets outside of the solar system.

  11. Mars Maven spacecraft
    Space

    NASA’s MAVEN probe shows how wind circulates in Mars’ upper atmosphere

    By using the MAVEN spacecraft to track winds in the Martian thermosphere, researchers hope to better understand how the atmosphere leaks into space.

  12. Parker Solar Probe illustration
    Space

    NASA’s Parker probe reveals the sun’s rogue plasma waves and magnetic islands

    Scientists have analyzed the Parker probe’s first data, giving a peek at what’s to come as the craft moves closer to the sun over the next few years.
