Stunning Real Images of Planet Formation

ALMA Image Reveals Planetary Genesis, ESO
“This new image from ALMA, the Atacama Large Millimeter/submillimeter Array, reveals extraordinarily fine detail that has never been seen before in the planet-forming disc around a young star. These are the first observations that have used ALMA in its near-final configuration and the sharpest pictures ever made at submillimeter wavelengths. The new results are an enormous step forward in the observation of how protoplanetary discs develop and how planets form.”
Keith’s note: This is a REAL IMAGE – not an artist’s concept. Update: here’s another – from Hubble.
Hubble Surveys Debris-Strewn Exoplanetary Construction Yards
“Astronomers using NASA’s Hubble Space Telescope have completed the largest and most sensitive visible-light imaging survey of dusty debris disks around other stars. These dusty disks, likely created by collisions between leftover objects from planet formation, were imaged around stars as young as 10 million years old and as mature as more than 1 billion years old.”
