Rubin Observatory detects giant asteroid spinning at record speed – suggesting it is “rock solid”

  • No comments
The first scientific article with data from the LSST camera describes a body with a diameter of about 710 meters that completes a full rotation every 1.88 minutes, demonstrating the ability of the Rubin Observatory to detect extreme phenomena in the solar system.

Gaia solves the mystery of asteroid rotation: Collisions and internal friction reveal the structure of "debris piles"

  • No comments
Analysis of data from the European Space Agency's Gaia mission reveals a sharp gap in the rotation patterns of asteroids – the result of a struggle between collisions and internal friction – and provides a new tool for deciphering the internal structure

Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape consisting of bright blue stars surrounding a yellow-white concentration of central stars. This concentration has a diagonal line of stars across it, called a bar. The galaxy is tilted inward to our view from Earth. A white S-shaped line slightly across the top is the Hubble image of an asteroid hovering across the field of view.. It looks dashed because the image is a composite of several exposures of the asteroid flying like a race car. Credit: NASA, ESA, PG Martín (Autonomous University of Madrid), J. DePasquale (STScI).
