'I was astonished': Ancient galaxy discovered by James Webb telescope contains the oldest oxygen scientists have ever seen
- Astronomers have discovered oxygen in the most distant known galaxy, JADES-GS-z14-0, formed at least 290 million years after the Big Bang.
- The detection of oxygen in this ancient galaxy challenges previous assumptions about the timeline of galaxy maturation.
- The presence of oxygen suggests that stars in the early universe were born and died at a faster rate, contributing to the rapid formation of galaxies.
- The reasons behind the rapid element seeding in galaxies like JADES-GS-z14-0 remain unknown and require further research.

Most distant known galaxy is mature in a baby universe
- The James Webb Space Telescope has detected oxygen in the most distant known galaxy named JADES-GS-z14-0.
- This discovery challenges our understanding of the early universe as stars were not expected to have produced heavy elements like oxygen at that time.
- JADES-GS-z14-0 formed very rapidly and is maturing faster than astronomers anticipated, indicating that galaxy formation occurs at a faster pace than previously thought.
- The detection of oxygen in the galaxy allows for precise distance measurements and contributes to refining our understanding of distant galaxy properties.

March equinox 2025: Here’s all you need to know
- The March equinox, also known as the vernal equinox, signifies the sun crossing above Earth’s equator from south to north, leading to the shift towards spring and summer in the Northern Hemisphere and autumn in the Southern Hemisphere.
- On March 20, 2025, at 9:01 UTC, the sun will cross the celestial equator, bringing various seasonal effects observed globally.
- During the equinox, both hemispheres receive the sun's rays equally, leading to the perception of equal day and night lengths, although not precisely accurate.
- The equinoxes witness the fastest sunsets and sunrises of the year due to the sun sinking below the horizon swiftly.
- At the equinox, the sun rises due east and sets due west, a phenomenon observed globally except at the North and South Poles.
- In the Northern Hemisphere, the March equinox brings earlier sunrises, later sunsets, and budding plants, while the opposite occurs south of the equator.
- The equinox is a result of Earth's tilt on its axis and its orbit around the sun, causing a balance in sunlight distribution between hemispheres.
- Nature reflects changes during the equinox, with longer days, migration of birds and butterflies northward, budding trees, and blooming flowers in the Northern Hemisphere.
- In contrast, the Southern Hemisphere experiences shorter days, longer nights, cooler temperatures, and the onset of fall and impending winter.
- The equinox serves as a reminder of Earth's continual orbit around the sun, bringing about seasonal transformations across the globe.

California is turning to satellites and AI to combat the next wave of deadly wildfires
- California is exploring the use of AI-powered satellites to combat wildfires fueled by global warming and worsened by the climate crisis.
- The Firesat network, comprising over 50 low-orbit satellites, aims to revolutionize mega-blaze firefighting efforts by providing real-time monitoring and data analysis.
- Current fire monitoring systems are often slow in responding to rapidly developing wildfires, posing challenges to containment efforts.
- Firesat's satellites, equipped with infrared sensors, will offer the ability to track smaller low-intensity fires and provide global observations at short intervals.
- Space startup Muon Space is behind the design and launch of Firesat satellites, with a prototype already launched in March this year.
- The goal is to scan the globe twice a day to identify fires as small as five by five meters, with a focus on early detection to prevent the escalation of fires.
- Google Research's backing and expertise in AI and machine learning will aid in processing the vast data expected from the Firesat constellation.
- Data generated by Firesat will be provided to public safety agencies for free, and collaborations with agencies like Cal Fire are already in progress.
- The integration of Firesat into emergency dispatch services could optimize the allocation of resources and improve response times to wildfires.
- With the increasing threat of extreme weather and wildfires, technologies like Firesat offer a smarter approach to fire monitoring and response.

Are day and night equal on the equinox? Not exactly
- The March equinox will come on Thursday, March 20, 2025, at 9:01 UTC (4:01 a.m. CDT). It’s the Northern Hemisphere’s spring equinox and Southern Hemisphere’s autumn equinox.
- You sometimes hear it said that, at the equinoxes, everyone receives about equal daylight and darkness. But there’s really more daylight than darkness at the equinox, eight more minutes or so at mid-temperate latitudes.
- Two factors explain why we have more than 12 hours of daylight on this day of supposedly equal day and night. They are: 1. The sun is a disk, not a point. 2. Atmospheric refraction.
- Bottom line: There’s slightly more day than night on the day of an equinox. That’s because the sun is a disk, not a point of light, and because Earth’s atmosphere refracts (bends) sunlight.

Scientists find giant gas reservoir in infant galaxy cluster
- Astronomers have discovered a massive hidden fuel source in a young galaxy cluster.
- Using the Atacama Large Millimeter/submillimeter Array (ALMA), they found a vast amount of molecular gas in a protocluster named SPT2349-56.
- This extra gas was previously hidden and forms a massive, spread-out reservoir surrounding the cluster.
- The presence of this hidden gas suggests that stars will continue forming in SPT2349-56 for more than 400 million years, challenging existing models of galaxy formation.
