    Explosive Material: The Making of a Supernova

    Weizmann scientists lead the team that observed - and measured - the earliest supernova explosion ever, an estimated three hours after it began. Tight coordination between multiple observatories and institutions enabled these unprecedented measurements, which were then analyzed by a global team.

    A Black Hole? Where?

    Guy Nir, a doctoral student at the Weizmann Institute, writes in The Jerusalem Post about black holes - e.g., what they are, how they are studied, and the like. This easy-to-read explanation sheds light on some of today’s greatest astrophysics discoveries.

    The Spectacular Aftermath of a Supernova Was Just Seen at Its Earliest Stage Ever

    The Washington Post reports on the remarkable recent observation of a supernova within just 3 to 10 hours of its explosion. A global network of astrophysicists - from California to Israel to Hawaii - collaborated in real time to take measurements of the supernova, the youngest ever witnessed. Weizmann’s Dr. Ofer Yaron was the lead scientist on the paper.

    StemRad’s Cosmic Ray Suit, Developed by Weizmann PhD, Set for Mars Trial

    Oren Milstein, who holds a PhD in immunology from the Weizmann Institute, is cofounder of StemRad - a company that has developed an innovative spacesuit that protects against cosmic rays, and is intended for use on trips to Mars. The Israel Space Agency and the Ministry of Science, Technology, and Space and the German Aerospace Center are launching the suit as part of the next trial flight of NASA's Orion satellite.

  • A Multiple-Impact Origin for the Moon

    While the predominant theory for the Moon’s existence was a single, massive impact with Earth, our satellite’s origins were still mysterious. Now, complex computer simulations by Prof. Oded Aharonson show that the more likely explanation is multiple impacts of varying sizes that produced many moonlets; over time, these joined to form the Moon we know today.

  • Burdick-TheManyMoonsTheory-800
    The Many-Moons Theory

    The New Yorker's Alan Burdick reports on the recent findings from Prof. Oded Aharonson's lab, which revealed that our moon was likely formed by multiple collisions, rather than the single-impact theory that prevails today.

  • 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.

    “Brightest Supernova Ever” Was Actually Monster Black Hole’s Violent Star Slashing reports on the recent finding by Weizmann astrophysicist Dr. Giorgos Leloudas revealing that what scientists believed to be a super-luminous supernova was actually a star being shredded by a black hole. The star was basically turned into "spaghetti," causing the very bright flash noted by observers.

  • 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.
