Leda 22057 It is located in the constellation Gemini, about 650 million light years away from Earth.
Also known as AGC 170923, MaNGA 11743-12703, or 2MASX J07524264+1450263, this galaxy is the site of a supernova explosion.
“This special supernova… SN2024piwas discovered by automated research in January 2024,” Hubble team members said in a statement.
“This survey covered the entire northern half of the night sky every two days and cataloged more than 10,000 supernovae.”
New images of LEDA 22057 consist of observations from. Hubble’s Wide Field Camera 3 (WCF3) Located in the infrared part of the spectrum.
“SN 2024pi is visible in this image,” the astronomers said.
“SN 2024pi’s pale blue dot, located just below and to the right of the galactic nucleus, stands out against the galaxy’s ghostly spiral arms.”
“This image was taken about a month and a half after the supernova was discovered, so the supernova appears many times fainter here than at its peak brightness.”
According to the researchers, SN 2024pi supernova belongs to type Ia.
“This type of supernova requires a remarkable object called a white dwarf, which is the crystallized core of a star with a mass less than about eight times the mass of the Sun,” the researchers said.
“When a star of this size runs out of hydrogen in its core, it expands into a red giant, becoming colder, swollen, and brighter.”
“Over time, pulsations and stellar winds strip away the star’s outer layers, leaving behind a white dwarf and a colorful planetary nebula.”
“White dwarfs can have surface temperatures of over 100,000 degrees Celsius and are extremely dense, packing almost the mass of the Sun into a sphere the size of Earth.”
“Nearly all stars in the Milky Way will someday evolve into white dwarfs, a fate that awaits our Sun in about 5 billion years, but not all of them will explode as Type Ia supernovae.”
“For that to happen, the white dwarf must be part of a binary star system.”
“If a white dwarf siphons material from its stellar partner, it could become too massive to support itself.”
“The resulting runaway fusion explosion destroys the white dwarf in a supernova explosion visible many galaxies away.”
