Similar to the gas giant planets Jupiter and Saturn, their smaller cousins, Uranus and Neptune, have long been known to harbor swirling clouds and violent winds churning up their atmospheres. Massive bands of jet streams encircling the entire planet have been observed in each case.
But given that Uranus’ atmosphere is believed to be thick enough to swallow Earth entirely, it was not known just how far the weather perturbations reach into the planet’s interior.

When a massive star reaches the end of its life, it can explode as a supernova. But there’s a unique type of supernova that’s much brighter that we’re just starting to understand – and which may prove useful in measuring the universe.
Known as superluminous supernovae, these events are typically 10 to 100 times brighter than a regular supernova but much more rare. We’ve spotted about 100 so far, but many aspects of these events remain elusive.

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.
