….Exoplanet Being Born. "At this point, we've spotted several thousand exoplanets—there's nothing super exciting anymore about finding a distant star with several worlds orbiting it. But today, scientists are announcing that they have seen an exoplanet in the middle of forming.
The dust disk of the star PDS 70 was detected by the Very Large Telescope's SPHERE and NAOS-CONICA instruments and the Gemini Near-Infrared Coronagraphic Imager, all located in Chile. But after re-analyzing data from the dust and taking further observations with SPHERE, scientists found what they were looking for: robust evidence of a spot in the dust.
"Planets are born in circumstellar disks. These disks are made out of gas and dust and surround young stars until a lifetime of about 10 million years," graduate student Miriam Keppler from the Max Planck Institute for Astronomy in Germany told Gizmodo. "The exciting fact of our discovery is that we have here an exceptionally robust detection of a young planet, still embedded in such a disk."…."

Very cool, but some here will have their shorts in a twist. Looks like lots of modelling is involved. Apparently that's not "real science". PDF link It's not Climate Science so we won't get the usual, "…..computer "models" with preconcieved outcomes" complaints. |

Too bad. I was expecting all manner of wild technobabble speculations over another super distant 4 pixel image. :) Dan
PS. Yet, as if coming from nowhere, another giant alien torpedo asteroid will be spotted already entering deep into our solar system and headed our way, and everyone will wonder how it snuck up on us like that.

I was expecting all manner of wild technobabble speculations over another super distant 4 pixel image. You did read that this particular circumstellar disk was discovered 26 years ago? …….and everyone will wonder how it snuck up on us like that. Who's everyone? Clearly finding an object in the scale of a few kilometers and moving at great speed is much more difficult than seeing a Jupiter plus sized exoplanet. |

Tango Don't be nervous. We go back and forth like this all the time. Dan |

That's right. Dan tends to go off kilter a bit and I'm here to keep him on an even keel. At least that's my take on it. His may be different. Good to see you're out of the big house, Dan. |

Thanks. Let's see for how long this time. :) Dan |
