President Donald Trump yesterday announced a phased ceasefire deal between Iran and Israel, reportedly brokered with the help of Qatar. Iran is expected to pause fighting first, followed by Israel 12 hours later, with the conflict ending as soon as tomorrow. The ceasefire was expected to go into effect around midnight ET. An Iranian official confirmed Tehran's agreement to the ceasefire as long as Israel stops its airstrikes, while Israel has not publicly acknowledged it as of this writing. See live updates here.
Trump's announcement on Truth Social came after Iran launched missiles at the US Al Udeid military base in Qatar in response to the US bombing of three Iranian nuclear facilities over the weekend. Roughly 10,000 troops are stationed at Al Udeid, the largest American military installation in the Middle East. Trump said Iran had provided advance warning of the missile strike, signaling a willingness to de-escalate. Nearly all of the missiles were intercepted, and no casualties were reported.
Earlier in the day, Israel struck the entrance to Iran's Evin prison, which houses political dissidents. See the nearly two-week conflict in maps here. |
The Vera C. Rubin Observatory in Chile released its first images this week, offering a detailed look into the distant universe. Funded by the US, the telescope features the world’s largest digital camera and an almost 28-foot-wide mirror, enabling it to capture enormous amounts of light and spot objects billions of light-years away with remarkable clarity.
Highlights include a composite of 678 exposures taken over seven hours, revealing new details in the Trifid and Lagoon nebulae—star-forming regions thousands of light-years from Earth—and a panoramic view of the Virgo Cluster (see images here). In 10 hours of observations, Rubin identified 2,104 previously unknown asteroids, including seven near-Earth objects, none of which pose a threat. There are an estimated 25,000 near-Earth asteroids large enough to destroy a city, fewer than half of which have been found.
Later this year, Rubin will launch a mission to scan the southern sky nightly for the next decade. The project is expected to shed light on dark matter, map the Milky Way, and create an inventory of our solar system. |
New York City voters head to the polls today for municipal primaries, including the mayoral race. Eleven candidates are running for the Democratic nomination—that winner is historically favored to win the general election.
The pack is led by former New York Gov. Andrew Cuomo, who returned to politics following sexual harassment allegations and ran a centrist campaign focused on public safety. He is expected to pull over 35% of the vote. New York Assemblyman Zohran Mamdani has closed in on Cuomo's lead, with the 33-year-old democratic socialist calling for universal child care, free bus rides, and a rent freeze on rent-stabilized apartments (roughly 44% of NYC rentals). One recent poll found Mamdani likely to win the nomination through the city’s ranked-choice voting system (see how it works here).
The winner will face the Republican and independent candidates, including incumbent Mayor Eric Adams, who skipped the Democratic primary and is running as an independent amid a since-dropped corruption investigation. Cuomo and Mamdani could also appear on the November ballot through additional party lines. |
