Moon craters hint huge asteroids bombarded Earth 800 million years ago
Craters on the moon show it was probably bombarded with asteroids about 800 million years ago, which also rained down on Earth and could have plunged the planet into an ice age Source: https://www.newscientist.com/article/2249457-moon-craters-hint-huge-asteroids-bombarded-earth-800-million-years-ago/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
UAE Successfully Launches Hope Probe, Arab World’s First Mission To Mars
The first Arab space mission to Mars has blasted off aboard a rocket from Japan, with its unmanned probe — called Al-Amal, or Hope — successfully separating about an hour after liftoff. The Guardian reports: The Emirati project is one of three racing to Mars, including Tianwen-1 from China and Mars 2020 from the United States, taking advantage of a period…

Washington Post: Asymptomatic ‘Superspreaders’ May Be Propelling the Pandemic
Saturday the Washington Post (in an article republished in Stars and Stripes) took a closer look at what’s known as “superspreading events”:
Many scientists say such infection bursts — probably sparked by a single, highly infectious individual who may show no signs of illness and unwittingly share an enclosed space with many others — are driving the pandemic. They worry these cases,…

New insights into the origins of our universe
New data released today by the Atacama Cosmology Telescope (ACT) in Chile indicate our universe is around 13.8 billion years old, matching the measurements made by the Planck satellite in 2015, and calling into question the 2019 findings of another research group that determined the age of the universe to be much younger than what the Planck satellite had predicted. That…
New research of oldest light confirms age of the universe
Just how old is the universe? Astrophysicists have been debating this question for decades. In recent years, new scientific measurements have suggested the universe may be hundreds of millions of years younger than its previously estimated age of approximately 13.8 billions of years. Now new research published in a series of papers by an international team of astrophysicists, including Neelima Sehgal,…
