Science AMA Series: We’re NASA scientists. Ask us anything about the Aug. 21 total solar eclipse!

Reddit science discussions - 8 hours 40 min ago

On Monday, August 21, 2017, daylight will fade to the level of a moonlit night as millions of Americans experience a total solar eclipse. For the first time in nearly 100 years (since 1918), the moon’s shadow will sweep coast-to-coast across the US, putting 14 states in the path of totality, and providing a view of a partial eclipse across all 50 states.

A solar eclipse happens when a rare alignment of the sun and moon casts a shadow on Earth. Eclipses provide an unparalleled opportunity for us to see the sun’s faint outer atmosphere, the corona, in a way that can’t be replicated by human-made instruments. We believe this region of the sun is the main driver for the sun’s constant outpouring of radiation, known as the solar wind, as well as powerful bursts of solar material that can be harmful to satellites, orbiting astronauts and power grids on the ground.

We’re here to talk about

• What you’ll see on August 21st & how to watch it safely

• Why we’re excited to study the sun during this eclipse & our upcoming mission to the sun

• How eclipses can help us learn about Earth, the solar system, and exoplanets

American Geophysical Union AMA: Hi Reddit, I'm Piers Forster, I am here to talk about what caused past global warming and what will happen in the future. I am currently Chair of Climate Physics and Director of the Priestley International Centre for...

Reddit science discussions - 8 hours 52 min ago

I'm Piers Forster and I principally research causes of past climate change and how well we can predict future climate change. I can take Qs on the evidence base for human-induced global warming and how much we should trust our climate model predictions of possible futures, including uncertainty in climate sensitivity – the Earth’s response to a doubling of carbon dioxide – one of the biggest uncertainties in climate science. I also lead an interdisciplinary centre looking at climate solutions, and I would welcome a discussion of ideas on possible solutions. Does solar geoengineering or large-scale carbon capture and storage have legs? Where should we concentrate research effort? Any whacky ideas we should look into?

I’ll be back at 11pm EDT to answer your questions. Ask Me Anything!

The AGU AMA series is conducted by the Sharing Science program. Sharing Science: By scientists, for everyone. More at sharingscience.agu.org.
