About Us
Founded in 1944, the American Committee for the Weizmann Institute of Science develops philanthropic support for the Weizmann Institute in Israel, and advances its mission of science for the benefit of humanity.

Tantalizing ‘signals’ from a handful of recent high-energy searches for dark matter are more likely the product of conventional astrophysics than the first tentative detections of the universe’s missing mass, say skeptical astrophysicists.

Smaller, lighter, faster to build, easier to launch and one-tenth the cost of today’s big space telescopes: That is the idea behind a unique collaboration between Weizmann Institute scientists and researchers in California, Israeli, and American industry, and NASA. The proposed project, says Institute astrophysicist Prof. Eli Waxman, could lead to a new era of research based on a number of small, special-purpose telescopes that will expand the boundaries of astrophysical research. Among other things, they might enable us to understand how black holes grow, or solve such mysteries as the sources of high-energy cosmic radiation.

In the search for life beyond Earth, Israel Space Agency (ISA) is among four finalists chosen by NASA to develop concept studies in NASA's Discovery Program for new missions. The ISA's proposal is to launch an investigative mission to Neptune's largest moon, Triton.
Each of the four finalists, who were selected out of a group of 22, is set to receive $3 million in the coming year to develop their plans before two are selected for missions.

REHOVOT, ISRAEL—May 14, 2020—An incredibly accurate clock planned by the Weizmann Institute of Science, the Israel Space Agency (ISA), and an Israeli company could be on its way to Neptune’s largest moon in 2026.
If life does exist outside of Earth in our Solar System, it could be hiding in subterranean oceans flowing under the surface of icy moons. One of the most promising candidates for such an underground liquid body is Triton – aptly named for the son of the sea god Neptune, the planet around which it orbits. Triton, Neptune’s largest moon, some 4.5 billion km (2.8 million miles) away, is an oddity: it orbits in the opposite direction from all of Neptune’s other moons. Some think this points to an origin outside of our Solar System: the moon may be an intruder that was trapped long ago by Neptune’s gravitational field.

Is there life on Triton, the largest moon circling the planet Neptune? An Israeli project aims to find out. One of its key measurement tools will be a super-accurate clock that loses less than one second every 10 million years.
But first, the Israeli project – dubbed “Trident” after the Roman sea god Neptune’s three-pronged spear – must be chosen by NASA to head to space.
Trident, sponsored by the Weizmann Institute of Science and the Israel Space Agency, is one of four projects chosen out of 22 proposals. Each project will now receive $3 million. However, only two will make the final cut for launch in 2026. The craft is expected to reach Neptune in 2038.

Small shadowed cold traps scattered across the lunar polar regions could contain up to 20 percent of the frozen water on the Moon, making accessing water sources easier for lunar visitors.
“Future lunar rovers may have a hard time driving into a large dark crater with extremely low temperatures. Small cold traps are far more accessible,” Planetary Science Institute Senior Scientist Norbert Schorghofer said. “Approximately 10 to 20% of the permanent cold-trap area for water is found to be contained in these micro cold traps. In terms of numbers, most cold traps are smaller than 1 meter.”
Dec 18, 2020... On December 21, 2020, stargazers are in for a once-in-a-lifetime cosmic event: Jupiter and Saturn will appear closer together than at any time in almost 400 years, in an event known as a great conjunction. Jupiter-Saturn conjunctions happen every 20 years. But this year’s happening will be the closest the planets have come since 1623. In this video, Ilan Manulis, Director of the Weizmann Institute’s Martin S. Kraar Observatory explains the science behind this celestial event and shares how to watch it.
Jan 12, 2021... In this special session, Prof. Avishay Gal-Yam, Weizmann’s supernova hunter, takes us to the Frontiers of the Universe: one of the Institute’s new flagship projects. From studying the tiniest subatomic particles to the far reaches of the galaxy, this initiative aims to put the Institute at the very forefront of advanced physics research – and even into space.

As we continue to be isolated so much of the time, it can be comforting (or not, depending) to know that we might not be alone. For instance, we recently encountered what the great Carl Zimmer characterized thusly: “A spooky radio signal showed up after a radio telescope was aimed at the next star over from our sun.”
The mysterious beam was the first big breakthrough from the Breakthrough Listen initiative – part of the Search for Extraterrestrial Intelligence (SETI) program – which scans the galaxy’s radio waves, looking for signals from intelligent life.
Jan 28, 2021... This webinar introduces Weizmann’s flagship Frontiers of the Universe initiative. Frontiers of the Universe will advance the Institute’s pioneering efforts to understand the nature of space, time, and life itself—from the tiniest subatomic particles to the largest galaxies.
