- Astronomers trace ghost particle to a distant star-forming galaxy
Astronomers linked a high-energy neutrino detected in 2021 by the IceCube Neutrino Observatory to a star-forming galaxy named Shadow Blaster, 11 billion light-years away. The study, led by Yuji Urata of MITOS Science Co. Ltd., suggests Shadow Blaster's dense, dust-filled star-forming environment may produce high-energy neutrinos, marking the first direct connection between such a galaxy and a neutrino event.
- Scientists trace latest interstellar comet’s home to a cold, isolated corner of the Milky Way
Scientists traced interstellar comet 3I/Atlas to a cold, isolated region of the Milky Way, suggesting it formed in a pre-solar system environment. The comet, estimated at 11 billion years old, exhibits high deuterium levels in its water, indicating origins in a colder, less heated stellar nursery. The University of Michigan-led study used the ALMA observatory and Hubble Space Telescope for analysis.
- Astronomers measure the mind-blowing power and speed of black hole jets for the first time
Astronomers measured the instantaneous power and speed of jets from the Cygnus X-1 black hole for the first time, finding they release energy equivalent to 10,000 suns and travel at 355 million mph. The study, led by Steve Prabu, used 18 years of radio imaging to analyze the black hole's interaction with its companion star.
