Scientists have finally pinpointed the source of mysterious, slowly repeating bursts of radio waves from space: a red dwarf star likely orbiting a white dwarf. This discovery challenges existing theories about pulsars and opens up new avenues of research into stellar interactions and radio wave emission.
A mesmerizing image from the Hubble Space Telescope reveals a ‘stellar volcano’ in action, showcasing the dramatic activity of a binary star system. The star, known as R Aquarii, is a symbiotic variable star, composed of a red giant and a white dwarf, which exhibit a spectacular dance of gravitational interaction. The Hubble observations provide unprecedented insights into the violent eruptions, swirling material, and vast scale of this cosmic phenomenon.
Astronomers have discovered a planet orbiting a white dwarf, providing a glimpse of what Earth might look like billions of years from now. The planet, twice the size of Earth, orbits a dying star in a system located 4,000 light-years away. This discovery offers insights into the future of our solar system, as our Sun is expected to transform into a white dwarf in the distant future.
