Hot exhaust gases churn in the wake of this climbing B-1B Lancer. The high temperature of the exhaust changes the density and, thus, the refractive index of the gases relative to the atmosphere. Light traveling through the exhaust gets distorted, making the highly turbulent flow visible to the human eye. Note how the four individual engine exhaust plumes quickly combine into one indistinguishable wake. This is typical for turbulence; it’s hard to track where any given fluctuations originally came from. The airplane’s wingtip vortices are just visible as well, if you look closely. (Image credit: T.

HAPPY 10TH ANNIVERSARY KAGAMINE RIN & LEN!!

Our team of mods are proud to present the 100 Kagamine Collaboration 2017, marking Rin and Len’s 10th anniversary. Congratulations to our wonderful and most precious VOCALOIDs!

Thank you to all the participants who finished their artworks and signed up for the collaboration. We achieved over 120+ applications in the first day alone, so this was a huge milestone for us. We couldn’t have done it without you!

Artist Credits PageCheck out all the wonderful artists who took part in this collaboration! If you’re an artist, be sure to tag your individual artworks as ‘100 Kagamine Collaboration’ so we can reblog it from you.

Once again, a very happy birthday to Rin and Len, the Kagamination will continue loving them for another 10 years!
