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

Space Debris Hits Florida House * Wake Up Call  

  • No comments
Although the chance of space debris directly hitting humans or property on Earth is relatively low, the risk is increasing as more and more objects are thrown into orbit around the Earth. Scientists and space explorers are calling for coordinated international action to address the problem and prevent catastrophic scenarios in the future

This image shows the sky goddess Nut, covered in stars, held aloft by her father, Shu, and towering over her brother with her back to the earth. On the left the rising sun (the falcon-headed god Re) sails up Nut's leg. On the right the setting sun sails down its arms to the outstretched arms of Osiris, who will recreate the sun in the underworld during the night.

The plan is to place five small satellites in space close to the Webb Space Telescope. Together these telescopes will act as a large telescope that will be used as an interferometer to receive infrared heat radiation from extrasolar planets. Finding life on Earth will give a good calibration of the spacecraft

This figure shows how CSOs are probably formed. When one massive star gets too close to a black hole (left), it is devoured. This causes the black hole to emit a very fast dipole jet (center). The jet extends outward and its hot edges glow with radio wave emissions (right). Credit: B. Saxton/NRAO/AUI/NSF

Scientists have discovered a large black hole that "hiccups", and emits gas fluxes. Analysis revealed that a small black hole repeatedly punctures the gas disk of the large black hole, causing the perturbations to be released. Strong magnetic fields, north and south of the black hole, shown by the orange cone, shoot the flux up and out of the disk. Each time the small black hole punctures the disk, it emits another star, in a regular periodic pattern. Credit: Jose-Luis Olivares, MIT
