The Nancy Grace Roman Space Telescope Arrives in Florida Ahead of Launch

NASA’s Nancy Grace Roman Space Telescope arrived June 21st, at the agency’s Kennedy Space Center in Florida, marking the start of final prelaunch preparations before liftoff later this summer.

Powerful Solar Storms Can Change Precipitation for Parts of North America

For decades, scientists have searched for a clear link between the Sun’s explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days following a solar storm, parts of North America can see sharp changes in the weather — such as declines in precipitation — and the more powerful the storm, the more dramatic the shift. However, the exact mechanism behind the effects is still waiting for an explanation.

The Galaxy That Cleared the Fog

For its first billion years the universe was lost in fog, a thick haze of hydrogen that swallowed light whole. Something burned it away, and astronomers have long wondered what. Now Hubble has caught a tiny, furious galaxy in the very act of clearing the murk, glimpsed as it was just 1.4 billion years after the big bang. It may be the smoking gun for how the universe first became clear.

Crystalline Clocks Confirm Earth's Oldest Crater

A chip of zircon found in Western Australian rocks at a place called North Pole Dome revealed the age of Earth's oldest known impact crater. The team that found it was working on age-dating the crater, which is located in a region called the Pilbara Craton. They used mineral dating to pinpoint the exact time it was dug out by an impactor. Team lead Chris Kirkland from the Timescales of Minerals Systems Group within Curtin University's School of Earth and Planetary Sciences, said the findings help resolve a longstanding question about the timing of the impact. The results of the team's analysis of several minerals at the site, along with zircon, indicated that the North Pole Dome impact occurred at 3.024 billion years ago (plus or minus a few million years).

Beyond Fermi's Paradox XVIII: What if We Make Contact?

Welcome to the final installment in the Fermi series, where we look at the impact that making contact with extraterrestrials could have and the rules governing how such an event should be treated.

Magnetic Fields Channel Gas Through Filaments into Star Formation Sites

Stars form inside molecular clouds where cold gas collapses gravitationally on itself. But there's more to this process than gravity. New research shows how magnetic field lines funnel gas through sub-filaments into star formation sites.

The Galaxy Living Too Fast

Twelve million light years away, a galaxy is living fast and burning bright, forging new stars ten times quicker than our own Milky Way in a frenzy that cannot possibly last. Now the James Webb Space Telescope has cut clean through its veil of dust to count an astonishing 16.5 million of its stars, one by one. So what is driving the Cigar Galaxy to burn so furiously?
