INBOX ASTRONOMY Aging White Dwarf Still Consuming Its Planetary System Release date: Wednesday, October 22, 2025 10:00:00 AM Eastern Daylight Time Dead star seen ripping planet apart. In approximately 5 billion years, the Sun will deplete its hydrogen fuel and collapse under its own gravity, becoming a white dwarf. Though Earth-sized, this dense remnant will retain much of the Sun’s gravitational influence. This transformation marks the end of our solar system as we know it. Or does it? The universe is neve ...Continue Reading
