Where are you right now? Until you interact with another particle you could be any number of places within a wave of probabilities. This is only one way that quantum mechanics challenges our perception of reality. Matt dives into these counter-intuitive ideas and explains the bizarre phenomenon known as quantum tunneling in this episode of Space Time.

Written and hosted by Matt O’Dowd.

AI discovers over 300 unknown exoplanets in Kepler telescope data

The AI algorithm is more efficient in distinguishing false positives from the real stuff than human experts.

A new artificial intelligence algorithm has discovered over 300 previously unknown exoplanets in data gathered by a now-defunct exoplanet-hunting telescope.

The Kepler Space Telescope, NASA’s first dedicated exoplanet hunter, has observed hundreds of thousands of stars in the search for potentially habitable worlds outside our solar system. The calatog of potential planets it had compiled continues generating new discoveries even after the telescope’s demise. Human experts analyze the data for signs of exoplanets. But a new algorithm called ExoMiner can now mimic that procedure and scour the catalog faster and more efficiently.

Physicists Outlined a Simple New Way to Create Antimatter

A group of researchers has outlined a surprisingly simple method for recreating the conditions near a neutron star, a breakthrough that could lead to new unimagined scientific discoveries revolving around the mysterious role of antimatter, a report from New Atlas explains.

The team of physicists designed a device, detailed in a paper in the journal Communications Physics, that fires two lasers at each other. The result is that the energy from the two lasers is simultaneously converted into matter, in the form of electrons, as well as antimatter, in the form of positrons.

NASA’s Parker Solar Probe Completes a Record-Setting Swing by the Sun

Blazing along at space-record speeds that would get it from Earth to the Moon in under an hour, NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. It’s vision is “To discover and expand knowledge for the benefit of humanity.”

“Incident” that Occurred During Loading Pushes the Webb Launch Date to Dec. 22nd

At Europe’s Spaceport near Kourou in French Guiana, technicians are busy getting the James Webb Space Telescope (JWST) ready for launch. The observatory arrived at the facility on Oct. 12th and was placed inside the upper stage of the Ariane 5 rocket that will carry it to space on Nov. 11th. The upper stage was then hoisted high above the core stage and boosters so that a team of engineers could integrate them.

Unfortunately, an “incident” occurred shortly after when the engineers attempted to attach the upper stage to the launch vehicle adapter (LVA) to the launch vehicle. According to a NASA Blogs post, the incident involved the sudden release of a clamp band (which secures the JWST to the LVA), which sent vibrations throughout the observatory. According to NASA, this incident could push the JWST’s launch date (slated for Dec. 18th) to Dec. 22nd.

A NASA-led anomaly review board was immediately convened to investigate the unexpected development and recommend how to proceed. The board recommended that additional testing be instituted to “determine with certainty” that the incident did not damage any components. NASA also indicated that it and its mission partners would provide an update when the testing is completed, which is expected to be by the end of this week.

Are Viruses Alive? — with Carl Zimmer

Are viruses alive or are they lifeless packages of protein and nucleic acid?
Watch the Q&A: https://youtu.be/-LUQTjdHYNo.
Carl’s book “Life’s Edge: The Search for What It Means to Be Alive” is available now — https://geni.us/zimmer.

Countless scientists around the world study life, and yet they can’t really agree on what it is. Join New York Times columnist Carl Zimmer as he explores the boundaries of life, encountering viruses and other strange residents of the borderlands.

Carl Zimmer is the author of fourteen books about science. Zimmer’s column “Matter” appears each week in the New York Times. His writing has earned a number of awards, including the Stephen Jay Gould Prize, awarded by the Society for the Study of Evolution. His book, She Has Her Mother’s Laugh, won the 2019 National Academies Communication Award. The Guardian named it the best science book of 2018.

Zimmer is a familiar voice on radio programs such as Radiolab and professor adjunct at Yale University. He is, to his knowledge, the only writer after whom both a species of tapeworm and an asteroid have been named.

This talk was recorded on 26 August 2021.
