we should be live at this point I think we'll see what happens someone has to say hello and then you all have to say hello uh and then of course we can do this too let's just go live and I could just go to the browser and they are tracking no issues you can see it is beautiful clear skies at Kennedy Space Center weather will not be a constraint for...

Questions & Answers

Q: What sets Lisa apart from ground-based gravitational wave observatories like LIGO?

Lisa has arms measuring 2.5 million km, enabling triangulation for more precise source location and can observe a different range of frequencies than LIGO, allowing it to detect supermassive black hole mergers and potential Big Bang gravitational wave signals.

Q: How does Lisa complement existing gravitational wave observatories?

Lisa's unique capabilities, such as detecting supermassive black hole activity and ancient gravitational wave imprints, complement the ground-based observatories like LIGO, providing a broader view of the gravitational wave spectrum and enabling new discoveries about the early universe.

Q: What significance do the new exoplanets discovered by Kepler hold?

The Kepler mission's latest release reveals hundreds of previously unknown exoplanets, including 10 in the habitable zone of their stars, expanding our knowledge of Earth-like planets and planet populations throughout the galaxy.

Q: How does Lisa's development pave the way for exploring the early universe's gravitational waves?

Lisa's potential to detect gravitational wave echoes from the universe's early stages before the cosmic microwave background offers a unique opportunity to study the universe's earliest moments and internal state, providing valuable insights into cosmic evolution.

Summary & Key Takeaways

• The Lisa mission by ESA starts design process for a 2034 launch, expected to provide insights into supermassive black holes, binary neutron stars, and potential gravitational wave imprints from the Big Bang.

• Latest Kepler release reveals hundreds of new exoplanets, including 10 in their star's habitable zone, shedding light on planet populations and rocky vs. gas planets.

• Possibility of Lisa detecting gravitational wave echoes from the early universe before the cosmic microwave background, offering a glimpse into the universe's state at an even earlier stage.
