    Searching for Dark Matter

    Astrophysicist Dr. Ron Budnik, recently recruited to the Weizmann Institute, is part of an international team of scientists that is creating new instruments in the hope of recording the first confirmed interactions between dark matter and normal matter. Dark matter is one of the biggest unsolved mysteries in physics.

    Weizmann Institute Instrument Bound for Jupiter

    The Institute is part of a European mission to Jupiter that aims to investigate our solar system's largest planet and several of its moons. Dr. Yohai Kaspi leads a team developing a super-precise atomic clock that will help scientists analyze atmospheric conditions. This will be the first time that an Israel device travels beyond Earth's orbit.

    Super Supernovae

    Weizmann astrophysicist Dr. Avishay Gal-Yam writes in Scientific American about his hunt for supernovae, which resulted in, among other discoveries, finding a type of explosion more powerful than previously thought possible.

    Israeli Eyes on Jupiter Orbiter

    NASA's Juno spacecraft will soon enter orbit around Jupiter – and the Weizmann Institute's Dr. Yohai Kaspi will be ready. He and other Institute researchers are part of a team of scientists who hope to answer pressing questions about the solar system's largest planet. Using tools Dr. Kaspi has developed, the team will have the opportunity to measure the differences in Jupiter's gravitational fields accurately and precisely – for the first time.

    Supernova Discovery Reveals how the Biggest, Brightest Stars Die

    Even in a universe of stars, astronomers know of only a few hundred of the largest and most luminous: Wolf-Rayet stars. As Fox News reports, Weizmann's Prof. Avishay Gal-Yam and international collaborators have shown that these stars – more than 20 times the mass of our sun – die in massive explosions, providing the ingredients for planets and life.

    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.""
