The ocean covers 71% of Earth’s surface while providing a playground in which natural and human factors interplay. Since the 1970s, satellites have been providing scientists with continuous information about the color of the world’s oceans. This has resulted in changing our scientific view about the impact that oceanic invisible life, phytoplankton, has on the rest of the living planet. With NASA’s upcoming mission, PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), we will continue those observations and add another dimension to them. Join Dr. Ivona Cetinić, the PACE Project Science Lead for Ocean Biogeochemistry, as she discusses how the PACE mission will unlock the story about the diversity of the ocean world that’s hidden from our eyes.

NASA’s Hubble Space Telescope is at its peak of scientific discovery, even after 33 years of operation from its perch in Earth’s orbit. Thanks to an outstanding oversight crew on the ground and five astronaut servicing missions, the observatory is in good technical condition and is making exciting new observations and discoveries. This non-technical talk will show some of the recent detections from Hubble, including activity in our solar system, beautiful star-forming nebulae, galaxies, exoplanet atmospheres, and the deep universe. Hubble is also revealing effects of mysterious unseen phenomena like dark energy, dark matter, and black holes.

Galactic cosmic rays provide information about what’s going on in our galaxy and what our planets are made of. While we have great experimental data available to understand various galactic processes, this data needs to be well supplemented by nuclear data. In this respect, scientists perform nuclear-related experiments, including one completed in March 2024 at an accelerator at Brookhaven National Lab where scientists blasted a few choice metals with protons. Join Dr. Priyarshini Ghosh, a nuclear astrophysicist at NASA’s Goddard Space Flight Center, as she discusses how these experiments will help us to better understand our own galaxy.

NASA's upcoming Nancy Grace Roman Space Telescope, a flagship astrophysics mission, will launch with a very special piece of technology on board that will directly observe exoplanets like never before: the Roman Coronagraph Instrument. The Roman Coronagraph, the most powerful coronagraph ever flown in space, will block the light from host stars, allowing scientists to directly observe exoplanets, or worlds beyond our solar system. The coronagraph is a technology demonstration that will show how this cutting-edge technology can work in space. These types of technologies will be necessary for future missions like NASA’s proposed Habitable Worlds Observatory mission concept.

From the enigmatic depths of space to the cutting-edge advancements in space technology, let's explore the existential questions that space provokes. Let's ponder the infinite together in a journey that transcends time and space.

Is faster-than-light (FTL) travel possible? In most discussions of this, we get hung up on the physics of particular ideas, such as wormholes or warp drives. But today, we take a more zoomed out approach that addresses all FTL propulsion - as well as FTL messaging. Because it turns out that they all allow for time travel. Join us today as we explore why this is so and the profound consequences that ensue.

A scientific take on the movie Interstellar.

Are We Alone In The Galaxy? is a question that has been on people's minds for a very long time. It's a question that makes us think about the vastness of space and whether Earth is the only planet with life. With about 2 trillion galaxies out there, it makes you wonder if we are really alone even just in the Milky Way galaxy. A new study from the University of Nottingham, published in the Astrophysical Journal, suggests that our galaxy could be home to 36 intelligent alien civilizations that can communicate. How did they come up with this number? They think this is actually a conservative guess. It's based on the idea that life forms on other planets in ways similar to how it does on Earth. The scientists in the study think Earth isn't unique. They imagine other planets like ours, circling stars like our Sun, with civilizations that advance technologically similar to how humans have. They assume it takes about 5 billion years for intelligent life to evolve, leading them to estimate at least 36 civilizations in our galaxy. Before, scientists used the Drake equation, which considers seven factors to estimate the number of intelligent civilizations. Those estimates were really broad, from none to a few billion. The new method refines this using more recent data and assumptions, suggesting there are likely between 4 and 211 civilizations that could talk to us, with 36 being the most likely number. But finding these civilizations is a whole different story. These scientists say they could be thousands of light years away.
