Jan 13, 2025 · The name “blue lurker” might sound like a villainous character from a superhero movie. But it is a rare class of star that NASA’s Hubble Space Telescope explored by looking deeply into the open star cluster M67, roughly 2,800 light-years away.

5 days ago · The term “blue lurker” might sound like a villain from a superhero movie, but it actually refers to a rare type of star. NASA’s Hubble Space Telescope recently studied this unique star in the open star cluster M67, located about 2,800 light-years from Earth. Data from Hubble reveals that the blue lurker has had a dramatic past ...

Jan 17, 2025 · Hubble observed the white dwarf companion star that the lurker orbits. Using ultraviolet spectroscopy, Hubble found the white dwarf is very hot (as high as 23,000°F, or roughly three times the ...

Jan 13, 2025 · But it is a rare class of star that NASA's Hubble Space Telescope explored by looking deeply into the open star cluster M67, roughly 2,800 light-years away. The name "blue lurker" might sound...

Jan 22, 2025 · The Hubble Space Telescope has discovered a rare "blue lurker" star that has been feeding on material from its two conjoined siblings. The fast-spinning star provides a detailed look at the...

Jan 17, 2025 · Hubble’s ultraviolet spectroscopy observation of the white dwarf companion to the blue lurker revealed that the dwarf is incredibly hot with temperatures reaching up to 23,000 degrees Fahrenheit, which is about three times the Sun’s surface temperature.

The name “blue lurker” might sound like a villainous character from the golden age of radio. In reality it is a rare class of star that the NASA/ESA Hubble Space Telescope explored by looking deeply into the open star cluster M67, roughly 2,800 light-years away.

Jan 15, 2025 · Determined to find out, Leiner and her colleagues attained and analyzed fresh Hubble Space Telescope observations of one of the brightest blue lurker stars in M67 — the results suggest it was ...

Jan 17, 2025 · A rare stellar phenomenon, termed the “blue lurker,” has been observed by NASA's Hubble Space Telescope within the open star cluster M67, located approximately 2,800 light-years away. This star, part of a unique triple-star system, has captivated researchers due to its unusual evolutionary history.

The blue lurker studied by Hubble provides valuable clues about their evolution. The white dwarf orbiting the blue lurker is more massive than expected (0.72 solar masses versus 0.5), suggesting ...
