Science history: First computer-to-computer message lays the foundation for the internet, but it crashes halfway through — Oct. 29, 1969

Tonight, if you turn your telescope towards the moon at sunset, you'll witness a stunning sight: a colossal 'X' and 'V' appearing on the lunar surface. This phenomenon occurs as sunlight highlights the broken terrain along the moon's terminator, creating a breathtaking view for skywatchers. It's a fantastic opportunity for astronomy enthusiasts and casual observers alike to connect with the wonders of our universe.

Tonight, skywatchers are in for a treat as Comet C/2025 A6, known as Lemmon, will glide through the neck of the magnificent celestial serpent, Serpens Caput. This rare cosmic event, occurring on the nights of October 26-27, offers a unique opportunity for stargazers to witness the beauty of our universe. It's a reminder of the wonders beyond our planet and a chance to connect with the cosmos.

Hurricanes are powerful tropical storms that are becoming more intense due to global warming. Understanding how they form and their increasing strength is crucial for preparing for their impacts on communities and ecosystems. As climate change continues to affect weather patterns, the knowledge about hurricanes can help in developing better strategies for disaster preparedness and response.

On October 29, 1969, a groundbreaking moment in technology occurred when the first message was sent between two computers over a distance of 380 miles, laying the foundation for what we now know as the internet. Although the message crashed halfway through, this event marked the beginning of a digital revolution that transformed communication and information sharing globally. Understanding this milestone helps us appreciate the incredible advancements in technology that have shaped our lives today.

The recent expedition to locate Ernest Shackleton's legendary ship, the Endurance, has led to an unexpected discovery beneath the Antarctic ice. An underwater robot uncovered a mysterious find that goes beyond just the shipwreck, sparking intrigue and excitement in the scientific community. This discovery not only sheds light on the historical quest for Shackleton's ship but also opens up new avenues for understanding the Antarctic ecosystem, making it a significant moment in both exploration and environmental science.

Russian cosmonauts Sergey Ryzhikov and Alexey Zubritsky have successfully completed a nearly seven-hour spacewalk to install experiments on the International Space Station. This achievement not only showcases the ongoing collaboration in space exploration but also contributes to scientific research that can benefit life on Earth. Such missions highlight the importance of international partnerships in advancing our understanding of space.

As Hurricane Melissa approaches, small island nations in the Caribbean are facing a dire situation, struggling with mounting debts from previous climate-related disasters. This highlights the urgent need for financial support to help these vulnerable communities prepare for and recover from such crises, as residents like those in Port Royal, Jamaica, take desperate measures to protect their livelihoods.

Texas has filed a lawsuit against Tylenol manufacturers Johnson & Johnson and Kenvue, alleging that they concealed risks linking acetaminophen use during pregnancy to autism. This lawsuit comes in the wake of controversial claims made by former President Trump, which have not been scientifically validated. The outcome of this case could have significant implications for public health and the pharmaceutical industry, as it raises questions about the safety of widely used medications during pregnancy.
