New Glenn launch: Blue Origin's reusable rocket set for maiden flight (New Scientist)

Quote

Blue Origin, the space company owned by Amazon founder Jeff Bezos, is set to launch its reusable New Glenn rocket for the first time on 10 January. If successful, the rocket could become a rival to SpaceX’s Falcon Heavy rocket, which has become the go-to launch vehicle for companies looking to put large payloads into orbit.

New Glenn is a 98 metre-tall rocket, around the height of a 30-storey building, designed to deliver payloads of up to 45 tonnes to low Earth orbit. It is expected to compete with SpaceX’s Falcon Heavy, which can carry about 64 tonnes of cargo.

The rocket has two stages. The first stage is designed to land on a sea platform, similar to Falcon Heavy, and Blue Origin claims it will be reusable for 25 missions. At the top of the rocket is a disposable upper stage where cargo and mission payloads can be stored.

The Blue Origin first stage was lost during re-entry, so at this stage it's still an expendable.

Meanwhile, the Starship upper stage exploded, but they did successfully capture the main booster. The FAA has grounded the launcher pending an investigation.

KM3NeT Telescope Detects Most Energetic Cosmic Neutrino Yet

A particle that rarely interacts with normal matter yet its "energy was roughly a 100 million billion times the energy of visible light photons..." Whoa. It's something called a cosmogenic neutrino.

A Spiral Found at the Solar System’s Edge—And It’s Full of Surprises

Quote

...a team of scientists recently ran simulations using NASA’s Pleiades supercomputer to model the structure of the Oort Cloud. They incorporated data on the orbits of long-period comets and factored in the gravitational influences not just from the Sun and planets but also from external cosmic forces. The result? A discovery that challenges everything we thought we knew: the inner Oort Cloud may not be a simple sphere after all. Instead, the simulations suggest it forms a spiral disk structure, much like a tiny, frozen version of the Milky Way galaxy. The simulations revealed that this spiral structure extends across the inner region of the Oort Cloud, between 1,000 and 10,000 AU from the Sun. Even more astonishingly, the spiral arms stretch up to 15,000 AU from end to end.

James Webb Telescope Spots Unprecedented Galaxy Rotation Pattern

Quote

These images showcase galaxies in the farthest reaches of the universe, many of which are billions of light-years away. What Shamir and his team found was a strikingly consistent pattern: the vast majority of these galaxies rotate in the same direction. Specifically, about two-thirds of the galaxies rotate clockwise, while roughly one-third rotate counterclockwise.

In a random universe, one might expect the rotation direction of galaxies to be distributed fairly evenly, with approximately equal numbers of galaxies rotating clockwise and counterclockwise. The fact that JWST’s observations show a clear preference for galaxies rotating in one direction suggests there might be an underlying cosmic phenomenon at play—one that is not immediately clear from existing theories of cosmology.

Things that make you go, hmm...

Well, more like scientific discoveries note made because of the Annoying Orange.

The reason? A hypothesis is that our universe was formed inside a rotating black hole. That's a pretty remarkable discovery if it pans out; it has been conjectured before, but this is the first actual evidence.

Juvenile colossal squid observed at natural depth:

 

Mesonychoteuthis hamiltoni was formally described and named 100 years ago, in 1925, based on two partial specimens found in the stomach of a sperm whale near the South Shetland Islands. However, no one has ever captured footage of a living colossal squid until now.

A slowly spinning universe could solve the Hubble tension

"Much to our surprise, we found that our model with rotation resolves the paradox without contradicting current astronomical measurements. Even better, it is compatible with other models that assume rotation. Therefore, perhaps, everything really does turn. Or, panta kykloutai," noted Szapudi.

Their model suggests the universe could rotate once every 500 billion years—too slow to detect easily, but enough to affect how space expands over time.

 

If true, it presents a nice, tidy package for our understanding of the big bang.

China’s CATL says it has overtaken BYD on 5-minute EV charging time

Quote

The world’s biggest electric vehicle battery maker said on Monday that a new version of its flagship Shenxing battery cell could offer a 520km (323mi) range from just five minutes of charging time. 

They've almost caught up to gasoline-powered vehicles now, which have an average range of 413 miles per tank.
