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.

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 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.

How were the Earth's solid deposits of iron ore created? While researching possible conditions on Mars, Dr. Itay Halevy discovered ""green rust"" - rare today, but apparently common billions of years ago. While this would have been just one of several means of iron deposition, green rust seems to have delivered a large proportion of iron to our early ocean.

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.|

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.

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.

Space.com 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.
