Latest Webb image shows what our Sun looked like as a baby protostar

Posted by in categories: nuclear energy, space

Webb’s NIRCam instrument recently captured this detailed image of the cloudy region around a very young protostar called L1527. Only about 100,000 years old, L1527 isn’t a star yet: it hasn’t fully pulled itself into a proper, stable sphere, and it hasn’t piled on enough mass to kickstart nuclear fusion and start pumping out its own energy. It’s more like “a small, hot, and puffy clump of gas, somewhere between 20 percent and 40 percent the mass of our Sun,” according to the European Space Agency.

But as the latest Webb photos reveal, the young protostar is making an ambitious start.

Early meteorites brought enough water to Mars to create a global ocean

Posted by in categories: chemistry, space

The meteorites that bombarded Mars during the early days of the inner solar system may have carried enough water to create a 300-metre-deep ocean on the planet.

Martin Bizzarro at the University of Copenhagen in Denmark and his colleagues have analysed the concentration of a rare chromium isotope, known as chromium-54, in samples of meteorites that have come to Earth from Mars to estimate how much water was deposited on the Red Planet by asteroids.

The uppermost layer of Mars contains the chemical signatures of carbonaceous, or C-type, meteorites that bombarded it as its crust solidified some 4.5 billion years ago.

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?

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].
