This illustration demonstrates how metapipeline-DNA processes raw genome sequencing data. It begins by aligning the sequence of DNA base pairs to a reference genome. Then produces sets of detected variants and other genetic and evolutionary features. Credit Yash Patel, Sanford Burnham Prebys

Fully corrected and calibrated albedos of Titan (yellow), Saturn (green), Uranus (blue), and Neptune (red) covering 0.3 µm to 2.1 µm, offset for clarity. Regions of strong telluric absorption are masked in lighter shades, and it should be noted that they are less reliably corrected. The flat regions in the UV were flagged as bad pixels in all images by X-shooter. We also highlight a vertical discontinuity between the VIS and NIR arms of Titan, which is likely due to weather inconsistency. The colors used for these objects are the same in the following figures. -- Astronomy & Astrophysics
