China's Zhuque-3 Reusable Rocket Passes Key Milestone
On Monday, Chinese company LandSpace executed a static-fire test with its 217-foot-tall Zhuque-3, a reusable rocket that China hopes will rival SpaceX. The rocket is on the way to its inaugural test flight expected at some point later this year.
This New Super Earth May Have Liquid Water And It's In Our Neighbourhood
Astronomers have found a new super-Earth only about 20 light years away. At that distance, it's a candidate for direct imaging.
Ancient DNA Reveals New Diseases behind Napoleon’s 1812 Russian Retreat
Disease-causing bacteria that have been recently discovered in the teeth of Napoleonic soldiers may have spurred the massive infantry’s demise during its retreat from Russia
XRISM Catches a Pulsar’s Cosmic Wind...and Sees a Surprising Result
The Universe is a strange place. The X-Ray Imaging and Spectroscopy Mission (XRISM) orbiting observatory recently highlighted this fact, when it was turned on a pulsar to document its powerful cosmic winds. The discovery comes courtesy of ESA’s Resolve instrument, a soft X-ray spectrometer aboard XRISM. The study looked at neutron star GX 13+1. This is a strong X-ray source located in the constellation Sagittarius, very near the galactic plane towards the core of our galaxy. GX 13+1 is about 23,000 light-years distant.

Teach-And-Repeat Driving Could Automate Lunar Cargo Delivery
Driving on the Moon for the first time has got to be an exhilarating experience. But driving the same path on the Moon for the 500th time probably won’t be nearly as exciting to whatever poor astronaut got stuck with that duty for the day. With that in mind, a team of researchers led by PhD student Alec Krawciw and Professor Tim Barfoot of the University of Toronto are working on a way to automate the mundane task of driving goods back and forth from a lunar landing site to a nascent lunar exploration base.
Are We In The Solitude Zone Of The Universe?
Are we alone? It’s probably one of the, if not the most basic questions of human existence. People have been trying to answer it for millennia in one form or another, but only recently have we gained the tools and knowledge to start tractably trying to estimate whether we are or not. Those efforts take the form of famous tools like the Fermi Paradox and the Drake Equation, but there’s always room for a more nuanced understanding. A new paper in Acta Astronautica from Antal Veres of the Hungarian University of Agriculture introduces a new one - The Solitude Zone.
