Sep 27, 2023 by News Staff

MilliMobile is a first of its kind battery-free autonomous robot capable of operating on harvested solar and radio frequency power. The MilliMobile prototype has a 1 x1 cm chassis and weighs less than 1.1 g. It can carry payloads 3 times its own weight, and only experiences a 25% reduction in speed when carrying a 1 g payload. MilliMobile is able to move across a variety of surfaces, including concrete and packed soil. Image credit: Mark Stone / University...

Schematic representation of the tilted accretion disk model. The black hole spin axis is assumed to be straight up and down in this illustration. The jet direction points almost perpendicular to the disk plane. The misalignment between the black hole spin axis and disk rotation axis triggers the precession of the disk and jet.

This Hubble image shows SDSS J103512.07+461412.2, a spiral galaxy some 23 million light-years away in the constellation of Ursa Major. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / R. Tully.
