Accessing Earth’s Core

Posted by in categories: engineering, space

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
All of our civilization exists only a thin layer of Earth’s surface, and our deepest mines barely scratch our planet. We often talk about finding new mineral resources on other worlds or asteroids in the future, but are we ignore a treasure beneath our feet, and what other technologies and engineering might we utilize in Earth’s depths?

Many have believed Earth might have a spirit, but Lovelock’s Gaia Hypothesis contemplates this as a scientific possibility. Could our world be alive itself?

Why We Need a Human Base on the Moon

Posted by in categories: futurism, space

What should be the future goal of the Moon exploration (after the Artemis launch was finally successful): A human base! We could do some amazing science with a human base on the Moon.

NASA’s Artemis I Cameras to Offer New Views of Orion, Earth, Moon

Posted by in categories: engineering, space

During Artemis I, NASA’s Space Launch System (SLS) rocket will send the agency’s Orion spacecraft on a trek 40,000 miles beyond the Moon before returning to Earth. To capture the journey, the rocket and spacecraft are equipped with cameras that will collect valuable engineering data and share a unique perspective of humanity’s return to the Moon.

Meteorite that landed in Cotswolds may solve mystery of Earth’s water

Posted by in category: space

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.

Probing the Limits of Nuclear Existence

Posted by in categories: mapping, physics, space

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].

Civilizations at the End of Time: Dying Earth

Posted by in categories: habitats, media & arts, quantum physics, space

A trip deep into the far future, to the End of Earth.
Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
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.

Galactica Demo

Posted by in categories: robotics/AI, space

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.
