Hubble Reveals Two Dust Disks Around Nearby Star Beta Pictoris

--------------------------------------------------------------------------------

Detailed images of the nearby star Beta Pictoris, taken by NASA's Hubble Space Telescope, confirm the existence of not one but two dust disks encircling the star. The images offer tantalizing new evidence for at least one Jupiter-size planet orbiting Beta Pictoris.

The finding ends a decade of scientific speculation that an odd warp in the young star's debris disk may actually be another inclined disk. The recent Hubble Advanced Camera for Surveys view – the best visible-light image of Beta Pictoris – clearly shows a distinct secondary disk that is tilted by about 4 degrees from the main disk. The secondary disk is visible out to roughly 24 billion miles from the star, and probably extends even farther, said astronomers. This Hubble image of Beta Pictoris clearly shows a primary dust disk and a much fainter secondary dust disk. Astronomers used the Advanced Camera’s coronagraph to block out the light from the bright star.

Hopefully. someday; there will be bigger better telescopes & cameras to actually view these extra stellar planets. I can't wait. More and more stars are found to have planets. I believe this is the norm rather than the exception.

Hello Orin

You seem to have a passion for space.

To go where no man has gone before,,,,,,,,,,,,,,,

I think we are all in the same boat.

The images above are just out of this world.

great post Harry,

Wow, 2 accretion disks! Is that because of the supposed gas giant?
Very cool!

I totally agree with Orin, planets everywhere...accretion disks are a natural part of the process of star formation.
But life sustaining planets? That's a much more difficult proposition, but in a universe of soooooo many stars, you've got to figure "it'd be an awful waste of space!" :)
Naaaak?...nknaknknaknkNAAK!

Hello All

All credit goes to Mr Hubble telescope.

But! I do collect all links


I may have to get a bigger computer.

Two disks maybe due to a shift in the axis of the star.

Here is another good link on Pictoris


which came from this one

http://www2.iap.fr/betapic/images/images_index_e.html

It is possible that it is debris being pulled out of the galactic plane by the orbit of a super jupiter sized planet that orbits through the main plane disk.

Hello All

The disk maybe a result from a pulling action by a companion object.

Or T

The companion object affects the jet stream direction realeased by the star.

The dusk disk is ringing! WOW,
...love to have that shifted into audible frequencies so we could hear it :)

Space is so cool!!! :)

...that said, brown dwarves don't sound so good, now do they ;)

Hello Raw

Brown Dwarfs

and other stars have their ending in a Black Hole either in the arms of the galaxy or near the centre or at the centre.

During that process , sometimes they get rejuvinated going through dust clouds.
