TW Hydrae (Annotated)

Shadow on TW Hydrae's Disk

These images, taken a year apart by NASA's Hubble Space Telescope, reveal a shadow moving counterclockwise around a gas-and-dust disk encircling the young star TW Hydrae. The two images at the top, taken by the Space Telescope Imaging Spectrograph, show an uneven brightness...

The Making of a Shadow in TW Hydrae's Disk

This diagram reveals the proposed structure of a gas-and-dust disk surrounding the nearby, young star TW Hydrae. The illustration shows an inner disk that is tilted due to the gravitational influence of an unseen companion, which is orbiting just outside the disk. The tilted...

Shadow on TW Hydrae Disk Visualization

This simulation shows a shadow sweeping around a gas-and-dust disk encircling the young star TW Hydrae. The simulated view is based on an analysis of data taken between 1998 and 2016 by NASA's Hubble Space Telescope. This video also shows what the moving shadow might look like...
