Dark matter detector opens new window to the Sun: neutrinos measured at lowest energy yet

Dark matter detector opens new window to the Sun: neutrinos measured at lowest energy yet

The XENONnT detector, built to search for dark matter, has detected with a precision of 5 sigma solar neutrinos at energies up to 17 kiloelectron volts. The group of Prof. Rani Budnik from the Weizmann Institute is a partner in the international study
Sun's shield shrank into Earth's orbit in the past—and may have contributed to ice ages

Models led by Haifa-born Prof. Meirav Ofer, director of NASA's SHIELD Center, indicate three encounters of the solar system with dense interstellar gas clouds. The clouds could have collapsed the heliosphere

A record-breaking radio burst from the Sun in August 2025 came from a structure in the Sun's atmosphere called a helmet stream. This image, taken during the total solar eclipse on August 21, 2017, shows the classic V-shape of a large helmet stream. Credit: Miloslav Druckmüller, Peter Aniol, Shadia Habbal/NASA Goddard, Joy Ng

NASA detected a solar radio burst that lasted 19 days

  • No comments
An unusual radio signal from the sun has lasted for 19 days, far beyond the normal duration of such bursts. NASA has linked the event to a giant magnetic structure in the sun's atmosphere, and it could help improve predictions

Analysis of 6,594 solar twins from Gaia data suggests a mass migration of sun-like stars from the inner regions of the Milky Way, perhaps at a time when the galaxy's central pole was still forming.

Curiosity's rear Hazcam recorded the shadow of the rover's rear in a 12-hour view toward the Gale Basin floor. Several factors caused several artifacts in the image, including a black spot, the sun's distorted appearance, and rows of white pixels extending from the sun. NASA/JPL-Caltech

An artist's rendering of a potential companion to the Sun, which theorists believe evolved in the Sun's natal cluster and then was lost. If proven, the companion sun theory would add credence to theories that the Oort cloud formed as we see it today, and the ninth planet was captured rather than formed in its place. Qualifying: M. Weiss

Did the sun start life as half of a pair of twin stars?

  • 14 תגובות
Harvard University scientists say the Sun may once have had a binary companion with a similar mass. If the theory is confirmed, the presence of an ancient companion star increases the likelihood that the Oort cloud formed as it is observed
