Where planets born

T Tauri stars are a class of variable stars that are less than about ten million years old. This class is named after the prototype, T Tauri, a young star in the Taurus star-forming region discovered in October 1852 by John Russell Hind. They are found near molecular clouds and identified by their optical variability and strong chromospheric lines. T Tauri stars are pre-main-sequence. In photo you can see 21 T Tauri stars with their protoplanetary disks, rotating circumstellar disks of dense gas and dust. This is probably the beginning of a solar system formation.

L1448-MM: water in space

posted by @ulaulaman about #Astronomy:

One of the most interesting research topics is the star formation. The high weigth chemistry elements could diffusein the universe only with the life cycle of the stars: the birth, the syntesis of helium and of the other elements, the great explosion that (diffusero) in space carbon, iron and so on. But also the early stages in star formation could send in cosmic vacuum some light elements like hydrogen, or also water!
One place in which it can observe not only star formation but also water jets is the L1448 dark cloud in Perseus molecular cloud

In particular there is an interesting object, L1448-MM that presents two bright spots of emission, the cross (A) and the star (B) in the following figure
