Heavy hydrogen in 3I/ATLAS's methane points to a frigid birthplace
Confirmed
In Short: These investments will support the deployment of EV charging and hydrogen refueling stations for light-, medium-, and heavy-duty ZEVs, solidifying California's position as a leader in ZEV infrastructure.
Funding from the Clean Transportation Program, alongside significant investments from public and private partners, has positioned California as the national leader in electric vehicle (EV) charging and hydrogen refueling infrastructure.
Meanwhile, the Nancy Grace Roman Telescope, launched on a SpaceX Falcon Heavy rocket, is set to explore the universe's mysteries, including the origins of heavy elements.
University of Arizona astronomers recently published a paper in Nature Astronomy revealing that heavy elements existed just 500 million years after the Big Bang, when the universe was only about 3% of its current age.
The researchers observed that heavy elements escaped from galaxies very early in cosmic time, suggesting that galaxies not only produced these elements but also dispersed them, possibly seeding other galaxies.
In their analysis of JWST data, the team found evidence that baryon cycling helped spread heavy elements throughout the early universe, challenging previous assumptions about the simplicity of the early cosmos.
Additionally, the Late Heavy Bombardment period, about 4 billion years ago, saw Earth experience some of its largest impacts, triggered by a planetary realignment.

What's still developing
- Plasma born of heavy hydrogen blooms into brilliant pink, roiling and writhing around the doughnut-shaped chamber.
- Astronomers found that the first stars were likely massive, formed from the abundant hydrogen available in the infant cosmos.
- Earth and Venus formed close to the Sun, where solar winds stripped their atmospheres of hydrogen and helium.
- “We used the galaxies themselves as background light sources,” said Zhu.
