Watch Live Webcast: Secrets of the Universe's First Light

By Nancy Atkinson - April 18, 2014 11:14 AM UTC | Cosmology

Just a month ago came

the news of the first direct evidence of primordial gravitational waves

— ripples in the fabric of spacetime — providing the first direct evidence the Universe underwent a brief but stupendously accelerated expansion immediately following the Big Bang.

This almost unimaginably fast expansion when the Universe was only a trillionth of a trillionth of a trillionth of a second was first theorized more than three decades ago, and the announcement last month was so monumental that some are comparing it to the discovery of the Higgs boson.

On April 18, 20:00 UTC (3 pm EDT, 1:00 pm PDT, two of the scientists who made this groundbreaking discovery will come together for a conversation with two of the pioneering leaders of the field. Together, they will examine the detection of a distinctive, swirling pattern in the universe's first light, what the swirl tells us about that monumental growth spurt, and the many implications on the way we understand the universe around us.

You can watch below:

The hangout will include members of the BICEP2, which made the discovery, as well as two notable scientists in this field, John Carlstrom and Michael Turner.

She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
