Permanent DST Could Leave California Mornings in Darkness

The House has approved a bill to make daylight saving time year‑round, which California could adopt or opt out of once federal rules align. If enacted, winter sunrises in California could be as late as about 8:00–8:44 a.m. in major cities, potentially forcing students to start school in the dark. Supporters argue for more evening daylight and safer, livelier communities, while critics warn of dark winter mornings and safety concerns. Federal law currently blocks permanent DST unless waived, and Senate support remains uncertain; California voters previously backed pursuing year‑round DST with Prop. 7, contingent on federal approval.

Dawn and the Blood Moon: A rare selenelion sight during March 3 lunar eclipse

Dawn and the Blood Moon: A rare selenelion sight during March 3 lunar eclipse

Space.com explains a rare phenomenon called selenelion, where the Sun rises as the Earth’s shadow falls on the Moon, making both visible at the same time due to atmospheric refraction during the March 3 total lunar eclipse (the last until 2028). The total phase lasts about 59 minutes starting at 3:03 a.m. PST. Visibility varies by location: western regions may witness the Moon near or in totality as it sets, while eastern areas can see dawn with the Moon still visible, and a brief 1–3 minute window may occur when both horizons show the Sun and the eclipsed Moon simultaneously. Observers should have clear eastern and western horizons and be mindful that daylight can wash out the Moon depending on conditions.

"Unveiling the Phenomenon: The Reverse Manhattanhenge Explained"

On Thursday morning, a rare "reverse" Manhattanhenge event will occur in New York City as the sun rises between skyscrapers, offering a unique spectacle for early risers. Unlike the traditional westbound Manhattanhenge, this event will be visible from the east and is best viewed at street level around 7:11 a.m. The intersection of 41st Street & 5th Avenue and spots along the Weehawken waterfront are recommended for optimal viewing. Additionally, upcoming full and half-sun Manhattanhenge events are scheduled for May and July, with specific dates and viewing locations provided.

NASA's Mini-Satellites Set to Shine in Space

NASA has completed the construction of six small satellites, known as SmallSats, for the Sun Radio Interferometer Space Experiment (SunRISE) mission. These cereal box-size satellites will work together to study solar radio bursts and gain insights into the physics of explosions in the Sun's atmosphere. By monitoring these bursts, scientists hope to better understand how they are created and linked to coronal mass ejections and solar flares. The data collected by the SmallSats will be combined to produce images of the Sun for further analysis. SunRISE will launch as a rideshare aboard a United Launch Alliance Vulcan rocket sponsored by the United States Space Force.

"Chicago's Daylight Saving Time Ends: Adjusting to Later Sunrises"

As summer comes to an end in Chicago, the days are getting shorter and the nights longer, signaling the end of daylight saving time. The last sunrise before 6 a.m. was on August 16, and the last sunset after 8 p.m. was on August 8. Daylight saving time will end on November 5, when clocks will be rolled back one hour at 2 a.m. Standard time is recommended by the American Academy of Sleep Medicine, as it aligns better with our body's internal clock and has health benefits.

The Mystery of the Green Flash at Sunrise and Sunset.

The Mystery of the Green Flash at Sunrise and Sunset.

The green flash is a rare phenomenon that occurs during sunset or sunrise when the atmosphere behaves like a prism, separating the stack of different-colored images of the sun. The green color is produced by atmospheric refraction of light, causing objects near the horizon to appear slightly higher in the sky than they really are. The green flash can be elusive, but it can be seen during very clear and exceptionally transparent skies. To catch a glimpse of the green flash, look for a distant, sharply-defined, and low horizon, and avoid looking at the sun until the last moment to avoid eye damage.
