Futuristic, 'alien-like' nuclear fusion rockets developed in total secret could revolutionize space travel — if they actually work
- A U.K. start-up, Pulsar Fusion, has unveiled plans for a nuclear fusion propulsion system to power reusable 'alien-like' rockets called Sunbirds for space exploration.
- The project has been in development in secrecy for a decade and could be in space by 2027, although no specific timeline has been set.
- Sunbirds use the Duel Direct Fusion Drive engines to harness nuclear fusion, potentially cutting travel time to Mars in half and reaching Pluto in 4 years.
- The technology involves fusion of deuterium and helium-3 for direct propulsion, with the reactor design being different from traditional tokamaks used on Earth.
- The feasibility of fusion in space remains uncertain, with differing opinions among experts about the challenges and possibilities of the technology.
- Sunbirds could act as 'space tugs,' propelling spacecraft out of Earth's gravity using minimal fuel and recharging at orbital docking stations for reuse.
- Initial tests of the DDFD engine are planned for this year, with an orbital demonstration of key components scheduled for 2027.
- The futuristic design of Sunbirds includes armor plating for protection in space and a potential cost of $90 million per rocket due to the expense of helium-3.
- Funding for a full-scale Sunbird prototype is contingent on successful tests, with uncertainty surrounding the timeline for its development and operational readiness.
- Experts predict it might take at least a decade to achieve a fully operational Sunbird prototype, highlighting the challenges and uncertainties in nuclear fusion propulsion technology.

'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.

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.
