    Fire and Ice on Mars

    The dry riverbeds, lakes, and valleys on Mars indicate that water once flowed there – but when? And how? Weizmann's Dr. Itay Halevy and Brown's Dr. James Head III have an interesting new answer: short, violent periods of intense volcanic activity that warmed the planet and turned ice into running water, which later froze again.

  • How the Mighty Winds of Uranus and Neptune Blow

    Giant planets are dominated by winds that can reach supersonic speeds; however, just how deep those winds reached was unknown … until now. reports on how the Weizmann Institute's Dr. Yohai Kaspi and team resolved what ""has been an open question for the last 25 years.""

    Earth-Mass Planet Right Next Door

    A potentially habitable planet – Proxima Centauri b – has been found virtually next door to Earth: about four light years away. Dr. Aviv Ofir, who is in Prof. Oded Aharonson's lab, is a member of the "Pale Red Dot" project; the team found that the new planet likely has balmy temperatures and liquid water, albeit a fast orbit. Further research is underway.

    Star Being Shredded Produces Unusual Super-Flash

    On June 14, 2015, astrophysicists around the world noted an extraordinarily bright flash of light that, puzzlingly, did not fit any of the usual explanations. Prof. Avishay Gal-Yam's lab has now solved the mystery: it was the destruction of a star by the gravitational tides of a black hole at the center of its galaxy. This event is extremely rare, as a number of physics conditions must be satisfied.

    Weizmann Scientists to Send Atomic Clock to Jupiter

    The European Space Agency is planning an international mission, JUICE, to investigate our solar system's largest planet: Jupiter. The Institute's Dr. Yohai Kaspi is playing a key role, leading the Israeli team developing a super-precise atomic clock that will help reveal information about the planet's atmosphere. <em>Israel21c</em> reports.

    The Israelis Who Went to Jupiter

    Weizmann planetary scientists, Drs. Yohai Kaspi and Eli Galanti, have played critical roles in NASA's Juno space mission. At NASA's visitors center in Pasadena, CA, they watched live as Juno went into orbit around Jupiter. Dr. Kaspi, the lead scientist on a team that will research Jupiter's atmospheric conditions, called the mission ""the realization of a dream.""

    He Drove Cars on Mars – Now He's Trying to Put Israel on the Moon

    Prof. Oded Aharonson was an astrophysics star at Caltech, including remotely driving NASA rovers on Mars. But when the Weizmann Institute offered him the opportunity to come home and help lead Israel into space, he couldn't say no. <em>Haaretz</em> interviews Prof. Aharonson, who heads the Center for Planetary Science and is guiding Israel's first moon shot.

    From Rehovot to Jupiter: Weizmann Science in Space

    July 4, 2016 was a day of celebration – not just in the U.S., but worldwide. It's when a long-awaited milestone was reached: after almost five years and 1.7 billion miles, the Juno spacecraft reached Jupiter, aiming to reveal the giant planet's secrets – and those of our solar system. The Weizmann Institute's brilliant young astrophysicists helped make it happen.
