The brief
Astronomers have identified four new white dwarfs—remnants of dead stars—within the Sun’s immediate stellar neighborhood. The discoveries were made using data from the Hubble Space Telescope, with researchers noting their proximity (within 65 light-years) as particularly notable.
These stars had evaded detection due to their faintness and low luminosity, despite their relative closeness to Earth. Coverage highlights the significance of the find, with *Sci.News*, *Earth.com*, and *BBC* emphasizing the role of Warwick University’s astronomers and Hubble’s capabilities in uncovering them. *IFLScience* and *Phys.org* underscore the rarity of such discoveries in such close proximity, framing it as a rare opportunity to study stellar evolution up close.
Further observations may reveal additional hidden white dwarfs, potentially reshaping models of stellar lifecycles in the solar vicinity. Astronomers could also investigate whether these stars have planetary systems or debris disks, offering clues about their past interactions with other celestial bodies.

Quick answers
How close are these newly discovered white dwarfs to Earth?
The four white dwarfs are located within 65 light-years of Earth, according to all reporting sources.
Which telescope or instrument was used to detect them?
The discoveries were made using data from the Hubble Space Telescope, as noted in multiple outlets.
Why were these stars not detected earlier?
Coverage suggests their faintness and low luminosity made them difficult to spot despite their proximity.
