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.

Jun 29, 2020... REHOVOT, ISRAEL—June 29, 2020—The history of our planet has been written, among other things, in the periodic reversal of its magnetic poles. Researchers at the Weizmann Institute of Science propose a new means of reading this historic record: in ice. Their findings, which were recently reported in Earth and Planetary Science Letters, could lead to a refined method of probing ice cores and, in the future, might be applied to understanding the magnetic history of other bodies in our solar system, including Mars and Jupiter’s moon Europa.

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.
Apr 21, 2021... In the latest episode of “Weizmann in Focus,” Dave Doneson invites us to gaze up at the stars and planets—and learn about the Institute’s efforts to uncover the mysteries of the cosmos. Dave highlights the ULTRASAT satellite mission, part of Weizmann’s flagship Frontiers of the Universe initiative, which will search for cosmic events such as supernovas and black holes. It will then alert astronomers around the world in real time to their occurrence. In partnership with NASA and others, Institute scientists plan to launch ULTRASAT into space in 2023.

For something that was to have been done and thrown away three years ago, NASA’s Juno spacecraft has a busy schedule ahead exploring Jupiter and its big moons.
The spacecraft entered orbit around Jupiter on July 4, 2016, and has survived bombardment from intense radiation at the largest of the solar system’s planets. It is now finishing its primary mission, but NASA has granted it a four-year extension and 42 more orbits. Last week, it zipped past Ganymede, Jupiter’s largest moon.
Jul 19, 2021... REHOVOT, ISRAEL—July 19, 2021—Until recently, before NASA’s Juno space probe entered its orbit around the planet Jupiter, no one knew that powerful cyclones approximately the size of Australia rage across its polar regions. Jupiter’s storms, as opposed to the earthly variety, do not disperse and rarely change. In an article published in Nature Geoscience, researchers from the Weizmann Institute of Science reveal the mysteries of Jupiter’s cyclones: which forces affix these gargantuan storms to their polar locations and why the storms’ numbers and locations remain more or less constant over time.
