Hayabusa2 Asteroid Samples Offer New Insights Into Conditions When The Solar System Formed

by Keith CowingMarch 4, 2026March 4, 2026

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials.

MIT scientists analyzed one of several particles (shown in black) from the asteroid Ryugu, and found evidence that a weak magnetic field likely existed in the outer solar system where the asteroid is thought to have first formed, more than 4.6 billion years ago. Credit Elias Mansbach

Asteroid Grains Shed Light On The Outer Solar System’s Origins

by Keith CowingNovember 7, 2024November 7, 2024

Tiny grains from a distant asteroid are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago.

(a) Stratigraphic column demonstrating the location of the second aquifer implemented in this section. (b) Ht across entire receiver array. The wide RIR signal arrival between 3 and 6 s is comprised of RIRs from the top of the lower aquifer and both interfaces of the shallower, newly placed aquifer. (c) Vr from receiver at x = 0. (d, e) Er and Ht, respectively. The addition of the new SE sources from the second aquifer is evident in the more complex RIRs. -- Computational simulation/modeling

Marsquakes May Help Reveal Whether Liquid Water Exists Underground On Mars

by Keith CowingJune 26, 2024June 26, 2024

If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars — […]
