This animation illustrates how debris from a tidally disrupted star collides with itself, creating shock waves that emit ultraviolet and optical light far from the black hole. According to Swift observations of ASASSN-14li, these clumps took about a month to fall back to the black hole, where they produced changes in the X-ray emission that correlated with the earlier UV and optical changes.Credit: NASA's Goddard Space Flight CenterWatch this video on the NASA.gov Video YouTube channel. || TD_Shocks_Still_print.jpg (1024x576) [115.2 KB] || TD_Shocks_Still.png (3840x2160) [32.6 MB] || TD_Shocks_Still.jpg (3840x2160) [922.7 KB] || TD_Shocks_Still_searchweb.png (320x180) [59.5 KB] || TD_Shocks_Still_thm.png (80x40) [4.8 KB] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_1080.mov (1920x1080) [50.7 MB] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_VX-280970_youtube_hq.mov (1920x1080) [25.7 MB] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_Good_1080.m4v (1920x1080) [44.4 MB] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_VX-280970_appletv.m4v (1280x720) [25.2 MB] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_Compatible.m4v (960x540) [10.2 MB] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_VX-280970_HD.wmv (1920x1080) [6.9 MB] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_Compatible.webm (960x540) [3.8 MB] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_VX-280970_appletv_subtitles.m4v (1280x720) [25.2 MB] || 12499_Tidal_Disruption_SRT_Captions.en_US.srt [509 bytes] || 12499_Tidal_Disruption_SRT_Captions.en_US.vtt [522 bytes] || 12499_Tidal_Disruption_Shocks_at_Apocenter_FINAL_ProRes_1920x1080_2997.mov (1920x1080) [591.1 MB] ||

Swift’s X-Ray Telescope captured the afterglow of GRB 221009A about an hour after it was first detected. The bright rings form as a result of X-rays scattered by otherwise unobservable dust layers within our galaxy that lie in the direction of the burst. The dark vertical line is an artifact of the imaging system.Credit: NASA/Swift/A.

Astronomers have discovered some of the youngest stars ever seen! The Herschel Space Observatory has looked at a vast stellar nursery located in the constellation Orion, considered the biggest site of star formation near our solar system. Dense envelopes of gas and dust surround fledgling stars (known as protostars) making their detection difficult until now. Hershel was able to spy these protostars by detecting far-infrared, or long-wavelength, light, which shines through those dense gas clouds. A portion of those observations is shown here in side-by-side images of the same region where new protostars were found. Of the 15 detected, four extremely young protostars are indicated here by small circles. The left-hand composite image, which includes the observations from Herschel in far-infrared light, shows the four young stars clearly. On the right is the same region using mid-infrared observations. Note that the same protostars in this image are undetectable. ||

Cassiopeia A, one of astronomy’s most famous supernova remnants, was created when a massive star blew up leaving behind a dense stellar corpse and its ejected remains. How supernovas explode, however, has been a mystery for a long time. With the help of NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), scientists have been able to see into the heart of a supernova explosion for the first time, by detecting high-energy X-rays emitted by the radioactive isotope titanium-44. This image of Cas A shows titanium concentrated in clumps at the remnant's center (in blue). The irregular distribution of the clumps strongly suggests that material at the heart of the exploding star literally “sloshed” around, thereby allowing the shockwave to escape the core of the collapsing star and blast off the star’s outer layers. This NuSTAR map shows high-energy X-rays generated by titanium-44, shown here in blue. Lower-energy X-rays from non-radioactive material, imaged previously with NASA's Chandra X-ray Observatory, are shown in red, yellow and green. ||
