Our Sun Escaped Together With Stellar Twins From Galaxy Center
Researchers have uncovered evidence for our Sun joining a mass migration of similar “twins” leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created […]

New High-resolution Images Of Protoplanetary Disks
Signs of planet formation may appear earlier than expected around still-forming baby stars, according to new results of higher resolution images produced using new improved techniques to reanalyze radio astronomy […]
![Stokes I (top), polarized intensity (PI) (middle) and polarization fraction (PF) (bottom) at 0.87, 1.3, 2.1 and 2.7 mm wavelengths plotted against right ascension (Δα) and declination (Δδ). Polarization vectors are also shown on the PI and PF images. The Stokes I and PI are converted to the brightness temperature (TB) by assuming the Rayleigh–Jeans approximation. The PF and polarization vectors are plotted where the polarized intensity is detected above the 3σ noise level. Contours on the PI and PF images indicate the brightness temperatures of the Stokes I emission of [0.1, 1, 10, 20] K for 0.87 mm, [0.1, 1, 5, 10, 20] K for 1.3 mm, [0.1, 1, 5, 9] K for 2.1 mm and [0.06, 0.3, 1, 3] K for 2.7 mm. The resolution (beam size) is shown as a small ellipse in the lower left corner of each panel. -- NAOJ](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/02/Stellar-Magnetic-Fingerprints.png?resize=1200%2C719&ssl=1)
