In Rare Show of Solidarity, 14 Key Nations Commit To Protect Oceans
When the heads of state of 14 nations sat down together in late 2018 to discuss the grim condition of the world’s oceans, there was no certainty that anything consequential would result. The leaders planned 14 gatherings, but met only twice before the pandemic upended their talks. So when the group announced this week the world’s most far-reaching pact to protect…
Growing interest in Moon resources could cause tension, scientists find
An international team of scientists led by the Center for Astrophysics / Harvard & Smithsonian, has identified a problem with the growing interest in extractable resources on the moon: there aren’t enough of them to go around. With no international policies or agreements to decide “who gets what from where,” scientists believe tensions, overcrowding, and quick exhaustion of resources to be…
Are There Active Volcanoes on Mars?
Mars is a dead planet — “Or is it?” asks the New York Times:
Previous research has hinted at volcanic eruptions on Mars 2.5 million years ago. But a new paper suggests an eruption occurred as recently as 53,000 years ago in a region called Cerberus Fossae, which would be the youngest known volcanic eruption on Mars. That drives home the prospect…
Hubble sees the brightest kilonova yet
Observations by the Hubble Space Telescope reveal intense infrared radiation from an unusual kilonova probably created by the collision of neutron stars. Source: https://earthsky.org/space/unusual-kilonova-infrared-light-neutron-stars-grb…
A Dead Soviet Satellite and An Old Rocket Booster Could Collide In Space Tonight
Space traffic experts are tracking two pieces of orbital garbage that appear to be careening toward each other: A defunct Soviet satellite and a discarded Chinese rocket booster that are expected to nearly miss each other — with a slight chance of colliding — Thursday evening. CNN reports: No one knows for sure if the objects will collide, and near-misses happen…
Astronomers see a star ‘spaghettified’ by a black hole
Astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon – known as a tidal disruption event – is the closest such flare recorded to date at just over 215 million light-years from Earth.

Microsoft and NASA Create a Space-Themed Site Teaching Python Programming
“To teach the next generation of computer scientists the basics of Python programming, Microsoft recently announced a partnership with NASA to create a series of lessons based on space exploration efforts,” reports TechRepublic:
Overall, the project includes three different NASA-inspired lessons… The Introduction to Python for Space Exploration lesson will provide students with “an introduction to the types of space exploration problems…
X-ray data reveal 1st-ever planet orbiting stars in another galaxy
While extragalactic “rogue” planets – not orbiting any star – have been reported before, the new exoplanet is the first to be detected orbiting stars in another galaxy. And not just any galaxy … but M51, the beautiful Whirlpool, 23 million light-years away. Source: https://earthsky.org/space/1st-exoplanet-in-another-galaxy-whirlpool-m51-uls-1b…
Teenager on TiKTok Resurrects an Essential Question: What is Math?
Long-time Slashdot reader fahrbot-bot shares a story that all started with a high school student’s innocuous question on TikTok, leading academic mathematicians and philosophers to weigh in on “a very ancient and unresolved debate in the philosophy of science,” reports Smithsonian magazine. “What, exactly, is math?” Is it invented, or discovered? And are the things that mathematicians work with — numbers,…
