HL Tauri
Protoplanetary disk
HL Tauri (abbreviated HL Tau) is a very young T Tauri star[5] in the constellation Taurus, approximately 450 light-years (140 pc) from Earth[1] in the Taurus Molecular Cloud.[6] The luminosity and effective temperature of HL Tauri imply that its age is less than 100,000 years.Laniakea

Superclusters – regions of space
that are densely packed with galaxies – are the biggest structures in
the Universe. But scientists have struggled to define exactly where one
supercluster ends and another begins. Now, a team based in Hawaii has
come up with a new technique that maps the Universe according to the
flow of galaxies across space. Redrawing the boundaries of the cosmic
map, they redefine our home supercluster and name it Laniakea, which
means ‘immeasurable heaven’ in Hawaiian.Read the research paper: http://dx.doi.org/10.1038/nature13674
