Great new episode with NASA cosmologist Jason Rhodes who discusses everything from the earliest galaxy surveys to dark matter and the cosmic web.

Jason Rhodes, a cosmologist at NASA’s Jet Propulsion Laboratory in Pasadena, and the JPL Roman Space Telescope Project Scientist, discusses a proposed galaxy survey to end all galaxy surveys. One that would wring as much information out of our universe’s trillion or so galaxies across cosmic time as humanly possible. Astronomers are still at least half a century off from this final galaxy census, but the hope is that it will give cosmologists most of the answers they need about the makeup and structure of the universe.

Researchers have discovered a way to camouflage microrobots in the body using white blood cells to pass through the blood-brain barrier.

The Ingenuity helicopter could pioneer a new way to explore space. In the future, drones may do reconnaissance for Mars astronauts and rovers.

These clocks could, in theory at least, keep time so accurately they’d gain or lose less than a second over the entire age of the universe.

Discovery may offer clues to carbon’s role in planet and star formation. Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons (PAHs). Since the 1980s, circumstantial evidence has indicated that these molecules are abundant in space.

Researchers using NASA’s upcoming James Webb Space Telescope will map and model the core of nearby galaxy Centaurus A.

As technology has improved over the centuries, so have astronomers’ observations of nearby galaxy Centaurus A. They have peeled back its layers like an onion to discover that its wobbly shape is the result of two galaxies that merged more than 100 million years ago. It also has an active supermassive black hole, known as an active galactic nucleus, at its heart that periodically sends out twin jets. Despite these advancements, Centaurus A’s dusty core is still quite mysterious. Webb’s high-resolution infrared data will allow a research team to very precisely reveal all that lies at the center.

Physicists from the LHCb Collaboration at CERN’s Large Hadron Collider (LHC) have observed four new exotic particles: Z_cs (4000)⁺, Z_cs (4220)⁺, X(4685), and X(4630). The new results provide grist for the mill of theorists seeking to explain the nature of tetraquark binding mechanisms.

“Hadrons discovered in the 1950-60s, the pioneering years in particle physics history, were called elementary particles till their structure was finally understood in the framework of quark model,” the LHCb physicists said.
