Asteroids

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).

Discovering new asteroids in old Hubble images

  • One response
Astronomers re-examined 37,000 images taken by Hubble over 19 years of objects in deep space. The reward was finding 1701 asteroid orbits in the asteroid belt, of which 1031 are uncatalogued asteroids. About 400 of these uncatalogued asteroids are roughly less than a kilometer in size

This figure illustrates how an interstellar object is rapidly approaching our solar system. Ejected from its home planet system long ago, the object traveled through interstellar space for billions of years before passing briefly in our cosmic neighborhood. The Robin Observatory will reveal many of these unknown interstellar visitors.

The precious metal-rich asteroid 16 Psyche may not be a solid lump of metal after all but a pile of rocks

The researchers based their work on previous observational data that showed the asteroid is primarily a mixture of three components: metal, low-iron pyroxene and carbonaceous chondrite. A laboratory experiment led the researchers to the conclusion that the density of the asteroid is low. A NASA spacecraft is expected to reach it by 2026

This dynamic image was taken by the 1A probe on September 22 at around 11:44 Japan time (15:44 Israel time). The image shows the surface of the asteroid Ryugo during a jump. In the left half of the image, the surface of Ryogo is visible, while the bright spot on the left side was created as a result of exposure to sunlight.
