Hubble Shoots Movies of Stellar Jets 30
With his first accepted submission, aglider writes "A number of different science publications are reporting on a recent announcement made by NASA and Hubblesite.org. Quoting: 'A team of scientists [headed by Rice astronomer Patrick Hartigan] has collected enough high-resolution Hubble Space Telescope images over a 14-year period to stitch together time-lapse movies of powerful jets ejected from three young stars. The jets, a byproduct of gas accretion around newly forming stars, shoot off at supersonic speeds in opposite directions through space.' The report is also accompanied by a number of photos and, of course, astounding small movies. The complete scientific study, which dates back to 2011.07.20, has been published in the Astrophysical Journal (subscription needed) but is also available on the ESA's Space Telescope site (PDF)."
