Tomorrow, July 12th, is the first anniversary of the James Webb Space Telescope (JWST). As a result, NASA has a few events planned that you may want to attend.
Webb mission experts will be available to conduct live, remote interviews with broadcast media, in both English and Spanish. Details about scheduling these interviews are available online. Webb experts also are available for interviews outside of this window upon request.
4 p.m.: NASA Science Live online
Two Webb experts will be featured on a NASA Science Live episode, discussing how Webb has made an impact in its first year on exploring the distant universe, characterizing exoplanet atmospheres, and understanding the solar system. The show will air live on the NASA Science Live website, as well as YouTube, Facebook, and Twitter. Viewers of this episode can submit questions on social media using the hashtag #UnfoldtheUniverse or by leaving a comment in the chat section of the Facebook or YouTube stream.
This past Sunday, 60 Minutes had a segment on Google and artificial intelligence (AI) called Exploring the human-like side of artificial intelligence at Google. Part of the discussion covered Google’s new AI chat bot Bard. And while the creative output of Bard was impressive, it was a little too creative when asked asked about economics. Bard recommended five books, but all five were nonexistent books. This is called “hallucination” in the AI realm.
I decided to try this myself, but ask for the five best books on black holes. This is what came back from Bard:
1. Black Holes: The BBC Guide by Andrew Hamilton. This book is a comprehensive introduction to black holes, covering their history, physics, and astrophysics. It is written in a clear and accessible style, and is perfect for anyone who wants to learn more about these fascinating objects.

3. A Brief History of Time by Stephen Hawking. This classic book is a must-read for anyone interested in black holes or cosmology. Hawking explains complex concepts in a clear and engaging way, and his book is full of insights into the nature of the universe. (link provided: https://www.amazon.com/Brief-History-Time-Stephen-Hawking/dp/0553380168)
4. Black Holes & Time Warps: Einstein’s Outrageous Legacy by Kip Thorne. This book is a more advanced treatment of black holes, but it is still written in a clear and accessible style. Thorne is one of the world’s leading experts on black holes, and his book provides a wealth of information about these fascinating objects. (link provided: https://www.amazon.com/Black-Holes-Time-Warps-Commonwealth/dp/0393312763)
5. The Little Book of Black Holes by Janna Levin. This book is a great introduction to black holes for people who are new to the subject. Levin writes in a clear and engaging style, and she uses humor and analogy to make the physics more accessible. (link provided: https://www.amazon.com/Little-Black-Holes-Science-Essentials/dp/0691163723)
Bard was even helpful enough to provide links to the books being cited.
After looking up these books, related authors, and links, here is what I found:
I could not find the first book by Andrew Hamilton, though he is a professor in the Department of Astrophysical and Planetary Sciences at Cornell University. Also, the link was to a different book.
The second, third, and fourth book references were accurate, as were the associated links.
The fifth book exists, but the authors are Steven S. Gubser and Frans Pretorius, not Janna Levin, who wrote other books on black holes.
So that gives you a 40 percent error rate on the 5 books listed. It does not inspire confidence. I am afraid to ask for the top 10 if only because it would take more time to correct this supposedly amazing chat bot.
And I do not really know if these are the top books in the field. Chat GPT gave me three of the five books listed, and also named the first book linked in Bard’s response, but attributed the lecture to Roger Penrose (the name of the lecture series) rather than Stephen Hawking.
Caution is highly recommended with these chat bots.

“Our findings open a new frontier in astronomy of studying what lies outside the solar system through microscopes rather than telescopes.”
-Statement by Harvard Professor Avi Loeb to USATodayregarding his recent recovery of what is believed to be fragments of an asteroid from outside our solar system that crashed into the Earth back in 2014. More tests are being conducted on the pieces recovered from the Pacific Ocean to determine whether the material is natural or artificially made. If the latter, it may be the first evidence of intelligent life beyond Earth.

On this day in 1933, American physicist and radio engineer Karl Guthe Jansky created the science of radio astronomy by publishing “”Radio Waves From Outside the Solar System” discussing his discovery that radio waves were emanating from the center of the Milky Way galaxy.
Unfortunately, Mr. Jansky was not a trained astronomer, so he was not in a position to develop the field of radio astronomy. He then died at the age of 44, which denied his the chance to earn a Nobel Prize for his finding, though he was nominated for the 1948 Nobel Prize in Physics.
Fortunately, the National Radio Astronomy Observatory’s (NRAO) Very Large Array was later rededicated as the “Karl G. Jansky Very Large Array,” an appropriate gesture to remember his incredible contribution to astronomy.

If you go to the OceanGate Expeditions website, home of the recently lost Titan submersible, you will notice two statements that say it all:
A PR blurb for interested tourists: “95% of the Earth’s ocean is unexplored. You can change that.”
And the current status of the expeditions for interested tourists: “OceanGate has suspended all exploration and commercial operations.”
Exploring is fine, but you are not helping to explore the other 95 percent of the Earth’s ocean if you keep going down to the same spot. In addition, “commercial” operations should not be resumed until safety is part of the package.
