Water covers three-quarters of the Earth’s surface and was crucial for the emergence of life, but its origins have remained a subject of active debate among scientists.

Now, a 4.6bn-year-old rock that crashed on to a driveway in Gloucestershire last year has provided some of the most compelling evidence to date that water arrived on Earth from asteroids in the outer solar system.

Researchers have discovered the heaviest-known bound isotope of sodium and characterized other neutron-rich isotopes, offering important benchmarks for refining nuclear models.

The neutron dripline marks a boundary of nuclear existence—indicating isotopes of a given element with a maximum number of neutrons. Adding a neutron to a dripline isotope will cause the isotope to become unbound and release one or more of its neutrons. Mapping the dripline is a major goal of modern nuclear physics, as this boundary is a testing ground for nuclear models and has implications for our understanding of neutron stars and of the synthesis of elements in stellar explosions. Now studies by two groups extend our knowledge of the properties of nuclei close to the dripline [1, 2]. Working at the Radioactive Isotope Beam Factory (RIBF) in Japan, Deuk Soon Ahn of RIKEN and colleagues have discovered sodium-39 (³⁹ Na), which likely marks the dripline location for the heaviest element to date (Fig. 1) [1].

A trip deep into the far future, to the End of Earth.

For most of human history, the end of Earth, the Universe, and Time itself were all identical, now we know the world will end in 4 billion years, long before the Universe begins to wind down. Today we will ask how we can extend that, and keep Earth around for far longer.

Take with a grain of salt and use at own risk:

Galactica is an AI trained on humanity’s scientific knowledge. You can use it as a new interface to access and manipulate what we know about the universe.

It turned out that Mars wasn’t as silent as first believed. Instead, there is intense seismic activity on the red planet, which is rumbling and groaning.

It’s not really a Star Wars story unless there’s a lovable or memorable droid stealing the spotlight. But, when you really stop and think about it, there’s also something profoundly tragic about the role artificial lifeforms play in the Star Wars universe.

China is the first country to operate a space station on its own. The country just launched the final module of its Tiangong orbital station.
