Has Earth been visited by an alien spaceship? Harvard Professor Avi Loeb vs. everybody else
A highly unusual object was spotted traveling through the solar system in 2017. Given a Hawaiian name,ʻOumuamua, it was small and elongated—a few hundred meters by a few tens of meters, traveling at a speed fast enough to escape the Sun’s gravity and move into interstellar space.

A combined map of almost 15,000 dust storms on Mars
Data in the world of astronomy is spread out in so many different places. There are archives for instruments on individual spacecraft and telescopes. Sometimes all that is needed to get new insight out of old data is to collect it all together and analyze a whole set rather than isolated instances. That is exactly what happened recently when a team…
‘We Need to Inflict Pain’: Mark Zuckerberg’s War on Apple
When Tim Cook told an interviewer that Apple wouldn’t get in a Facebook-style data-collection controversy, “Mr. Zuckerberg shot back that Mr. Cook’s comments were ‘extremely glib’ and ‘not at all aligned with the truth,'” reports the Wall Street Journal. But “In private, Mr. Zuckerberg was even harsher. ‘We need to inflict pain,’ he told his team, for treating the company so…

Fossil Fuels Caused 8.7 Million Deaths Globally in 2018, Research Finds
Air pollution caused by the burning of fossil fuels such as coal and oil was responsible for 8.7 million deaths globally in 2018, a staggering one in five of all people who died that year, new research has found. From a report: Countries with the most prodigious consumption of fossil fuels to power factories, homes and vehicles are suffering the highest…
The 1st sign of intelligent life beyond Earth?
Physicist Avi Loeb of Harvard believes we should take seriously the idea that ‘Oumuamua – the 1st known object to pass through our solar system from interstellar space – might have been created by an alien civilization. His new book is called “Extraterrestrial.” Source: https://earthsky.org/space/book-avi-loeb-extraterrestrial-1st-sign-of-intelligent-life…
Implementing a quantum approximate optimization algorithm on a 53-qubit NISQ device
A large team of researchers working with Google Inc. and affiliated with a host of institutions in the U.S., one in Germany and one in the Netherlands has implemented a quantum approximate optimization algorithm (QAOA) on a 53-qubit noisy intermediate-scale quantum (NISQ) device. In their paper published in the journal Nature Physics,, the group describes their method of studying the performance…
Harvard astronomer argues that alien vessel paid us a visit
