Found: Metal-rich Star. Parents Being Sought.

A ninth-magnitude star in our neighborhood of the Milky Way has been found to contain 65 different elements, including large proportions of heavier elements like gold. This star required either a supernova or a neutron star merger to form. Plus, another solar flare, a strong marsquake, cosmic rays, cookies, and this week in rocket history, we look back at STS-84.

New Analysis Reveals W Boson Particle Far Heavier Than Expected

New Analysis Reveals W Boson Particle Far Heavier Than Expected

Despite being shut down a decade ago, the Collider Detector at Fermilab provided enormous amounts of data, some of which have recently been re-analyzed, leading to the discovery that the W boson is actually more massive than calculations and predictions expected. Plus, another JWST update, the newest most distant galaxy, gravitational waves, and an interview with Dr. Kelsi Singer about cryovolcanoes on Pluto.

Theory and Observation Combine to Update Galaxies and Stars

Theory and Observation Combine to Update Galaxies and Stars

Today, our view on the universe gets itself an update thanks to the combined efforts of theorists and observers. From a new understanding of how galaxies can lose their dark matter, to how white dwarfs can be resurrected into helium-burning stars, we have the weird, the wonderful, and in the case of a new lunar tracking system, we even have a touch of the mundane. Plus, this week in rocket history, we look back at STS-82 which serviced the Hubble Space Telescope.
