Oprosti Arkture što ne čitam tvoje postove

Ps
Ja ih isto ne čitam. Slučajno sam nabasao na jedan.

Hehehe, kostelac vam je govorio godinama o nevidljivom patuljku u sunčevom sustavu, a vi ga niste slušali.

... o nevidljivom patuljku u sunčevom sustavu, ...

Sad ih je ostalo za otkriti još samo 6.

Sad ih je ostalo za otkriti još samo 6.

Ovaj prvi se zove Nibirko!

Dao bi se kladiti da kostelac sada negdje po bespućima interneta šizi: "Što sam vam ja govorio sve ove godine?!?!"

nasla je ALMA jos toga..

Nešto slično je otkriveno još kraj zvijezde W Aql

The unprecedented sensitivity of the Atacama Large millimeter/submillimeter array (ALMA) is providing many new discoveries. Several of these are serendipitous to the original goal of the observations. We report the discovery of previously unknown continuum sources, or a single fast moving new source, in our ALMA observations. Here we aim to determine the nature of the detections. The detections, at >5.8\sigma in the image plane and >14\sigma in the (u,v)-plane, were made in two epochs of ALMA observations of a 25 arc second region around the asymptotic giant branch star W Aql in the continuum around 345 GHz. At a third epoch, covering 50x50 arcseconds, the source(s) were not seen. We have investigated if the detections could be spurious, if they could constitute a population of variable background sources, or if the observations revealed a fast moving single object. Based on our analysis, we conclude that a single object (with a flux of \sim3.0 mJy) exhibiting a large proper motion (\sim87 arcsec/yr) is the most likely explanation. Until the nature of the source becomes clear, we have named it Gna. Unless there are yet unknown, but significant, issues with ALMA observations, we have detected a previously unknown objects in our solar system. Based on proper motion analysis we find that, if it is gravitationally bound, Gna is currently located at 12-25 AU distance and has a size of \sim220-880 km. Alternatively it is a much larger, planet-sized, object, gravitationally unbound, and located within \sim4000 AU, or beyond (out to \sim0.3~pc) if it is strongly variable. Our observations highlight the power of ALMA in detecting possible solar system objects, but also show how multiple epoch observations are crucial to identify what are otherwise probably assumed to be extra-galactic sources.

Dobar članak na temu. Bio je u komentarima korisnika na Bojanovom linku pa ga možda nisu svi vidjeli.
