    AI has found an 8-planet system like ours in Kepler data

    Our solar system is no longer the sole record-holder for most known planets circling a star.

    An artificial intelligence algorithm sifted through data from the planet-hunting Kepler space telescope and discovered a previously overlooked planet orbiting Kepler 90 — making it the first star besides the sun known to host eight planets. This finding, announced in a NASA teleconference...

    Saturn’s rings are surprisingly young and may be from shredded moons

    NEW ORLEANS — Saturn’s iconic rings are a recent addition. Final data from the Cassini spacecraft, which flew between the planet and the rings this year before plunging into the gas giant’s atmosphere, show the rings are around a few hundred million years old and less massive than previously thought.

    Those findings suggest the rings are probably the remnants of at least one moon, rather...

    2017 delivered humility, and proved our potential

    The Top 10 science stories of 2017, selected by Science News staff and presented in this year-end issue, have the potential to make you feel small and certainly humble. Our No. 1 story of the year takes place an unfathomably distant 130 million light-years away, where a neutron star smashup produced, by some estimates, 10 Earth masses worth of gold — wow! That’s enough for many trillions of...

    This year’s neutron star collision unlocks cosmic mysteries

    Thousands of astronomers and physicists. Hundreds of hours of telescope observations. Dozens of scientific papers. Two dead stars uniting into one.

    In 2017, scientists went all in on a never-before-seen astronomical event of astounding proportions: a head-on collision between two neutron stars, the ultradense remnants of exploded stars.

    The smashup sent shivers of gravitational...

    Seven Earth-sized planets entered the spotlight this year

    Discoveries of planets around distant stars have become almost routine. But finding seven exoplanets in one go is something special. In February, a team of planet seekers announced that a small, cool star some 39 light-years away, TRAPPIST-1, hosts the most Earth-sized exoplanets yet found in one place: seven roughly Earth-sized worlds, at least three of which might host liquid water (SN: 3/18...

    New Horizons’ next target might have a moon

    NEW ORLEANS — The New Horizons team may get more than it bargained for with its next target. Currently known as 2014 MU69, the object might, in fact, be two rocks orbiting each other — and those rocks may themselves host a small moon.

    MU69 orbits the sun in the Kuiper Belt, a region more than 6.5 billion kilometers from Earth. That distance makes it difficult to get pictures of the...

    Jupiter’s massive Great Red Spot is at least 350 kilometers deep

    NEW ORLEANS — Jupiter’s Great Red Spot has deep roots. Data from the first pass of NASA’s Juno spacecraft over the incessant storm show that its clouds stretch at least 350 kilometers down into the planet’s atmosphere. That means the storm is about as deep as the International Space Station is high above the Earth.

    Juno has been orbiting Jupiter since July 4, 2016, and it made its first...

    Most complete map of Titan reveals connected seas and cookie-cutter lakes

    Liquid methane and ethane flow through a subterranean plumbing system on Titan, which drains lakes and connects seas. That’s one of the first scientific results from the latest, most complete map of the Saturnian moon’s topography.

    Planetary scientist Paul Corlies of Cornell University and colleagues released the map — based on all the data from NASA’s Cassini mission, which ended in...

    The most distant quasar ever spotted hails from the universe’s infancy

    The most distant quasar yet spotted sends its light from the universe’s toddler years. The quasar, called J1342+0928, existed when the universe was only 690 million years old, right when the first stars and galaxies were forming.

    Quasars are bright disks of gas and dust swirling around supermassive black holes. The black hole that powers J1342+0928 has a mass equivalent to 800 million...
