Stunning Hubble Timelapse Reveals Explosive Beauty of R Aquarii's Dueling Stars
  • Ultimately, this process illustrates that humans are made of 'star stuff,' as the materials in our bodies originated from the cores of stars.

  • Scientists have compiled a timelapse video from five years of Hubble images, illustrating the brightness changes of the stars and the nebula's evolution.

  • This unique timelapse, created by the European Space Agency and based on Hubble data from 2014 to 2023, highlights the dynamic nature of the R Aquarii system.

  • The study of novae like R Aquarii is crucial for understanding how elements necessary for new stars and life are recycled in the universe.

  • NASA's Hubble Space Telescope has been observing the binary star system R Aquarii for over 30 years, located approximately 700 light-years from Earth.

  • R Aquarii consists of an aging red giant star, which is over 400 times the size of the Sun and shines nearly 5,000 times brighter at its peak, and a compact white dwarf.

  • The white dwarf orbits the red giant every 44 years, siphoning hydrogen gas, which leads to explosive outbursts resembling 'gigantic hydrogen bombs.'

  • These violent eruptions occur as the white dwarf draws material from the red giant, resulting in massive explosions on the dwarf's surface.

  • During these outbursts, material is ejected into space at speeds exceeding 1 million mph, forming twisted gas streamers that give the surrounding nebula a unique appearance.

  • The system releases gas streams that extend 248 billion miles into space, significantly farther than the diameter of our solar system.

  • Remarkably, the emitted material has been traced to distances of at least 248 billion miles from the star, showcasing the vast reach of these cosmic events.

  • Hubble's latest observations reveal that the ejected material has formed a spiral pattern due to the explosive forces and magnetic fields at play.
