Japan’s Hayabusa 2 Targets Final Asteroid Landing
The team overseeing the Hayabusa2 mission for the Japan Aerospace Exploration Agency (JAXA) is putting the vehicle through its paces one more time as it prepares to release the last rover it has on board. “That rehearsal, which took place Sept. 16 (Sept. 17 local time at mission control), sent two target markers toward the asteroid,” reports Space.com. From the report:…
Physicists discover topological behavior of electrons in 3-D magnetic material
An international team of researchers led by scientists at Princeton University has found that a magnetic material at room temperature enables electrons to behave counterintuitively, acting collectively rather than as individuals. Their collective behavior mimics massless particles and anti-particles that coexist in an unexpected way and together form an exotic loop-like structure. …
Did an asteroid collision cause an ice age on Earth?
Could a collision between 2 asteroids millions of miles away cause an ice age on Earth, some 460 million years ago? A new study of earthly rocks and sediments – plus micrometeorites that fell in Antarctica – suggest it’s possible.

AIDA collaboration highlights case for planetary defence
Surprising results from recent asteroid missions have highlighted the importance of testing planetary defence strategies in space, according to scientists participating in the joint ESA/NASA Asteroid Impact and Deflection Assessment (AIDA) collaboration. The unexpectedly large crater on asteroid Ryugu created by the JAXA Hayabysa2 impactor, together with the sand-like behaviour of material on its surface, further motivate the need to determine…
Are Saturn’s rings young or old?
Cassini data suggested that Saturn’s rings were only 10 to 100 million years old. A new study suggests that a “ring rain” onto Saturn makes the rings look younger than they really are, and that in fact Saturn’s rings date back billions of years.

Tsunamis, wildfires followed dinosaur-killing impact
A new study that analyzed rock from deep within the Chicxulub impact crater helps reveal what happened within the first 24 hours after the asteroid impact that doomed the dinosaurs. Source: https://earthsky.org/earth/tsunamis-wildfires-dinosaur-killing-asteroid-impact…
Milton’s Notes On Shakespeare Appear To Have Been Found
Almost 400 years after the first folio of Shakespeare was published in 1623, scholars believe they have identified the early owner of one copy of the text, who made hundreds of insightful annotations throughout: John Milton. The Guardian reports: The astonishing find, which academics say could be one of the most important literary discoveries of modern times, was made by Cambridge…
MIT Unveils New ‘Blackest Black’ Material and Makes a Diamond Disappear
An anonymous reader shares a report: What do you do with a $2 million natural yellow diamond? If you’re at the Massachusetts Institute of Technology, you coat it in a wild high-tech material that makes any object look like it fell into a black hole. The coated diamond is now a piece of art called The Redemption of Vanity, a collaboration…
