Some Young Suns Align With Their Planet-forming Disks, Others Are Born Tilted
Researchers at UC Santa Barbara, The University of Texas at Austin, Yale University and National Taiwan Normal University have found that a fair number of sun-like stars emerge with their […]
![a, NIRCam false-colour image, where each colour channel was constructed by stacking NIRCam filters as annotated. The placement of the NIRSpec micro-shutters is shown in white (nearly identical across the all visits). Dashed coloured circles indicate the 0.3 "-diameter apertures used to extract the CIRC2 photometry. The [O iii] 88 µm emission and the MIRI/F560W image are overlaid with red and green contours respectively, both drawn at 3σ-4σ-5σ. A red (green) hatched ellipse shows the ALMA restoring beam (F560W point spread function). A horizontal bar indicates a physical scale of 1 kpc at z = 11.122. b, SEDs of the main component (A) of JADES-GS-z11- 0, as observed by NIRCam, MIRI, and NIRSpec/PRISM (Section 2.1), as well as the faint neighbouring source (B) whose photometry (filter curves drawn at the bottom) is consistent with having the same redshift. The best-fit bagpipes models are shown as solid (component A) and dashed (B) coloured lines, with squares indicating the model photometry. c, Best-fit model SFHs of the two components, with shading representing 1σ uncertainty. The dotted black line and grey shading illustrates the rising SFH prior based on dark matter halo accretion (see text for details), scaled to the stellar mass of component A. -- astro-ph.GA](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/08/On-The-Origins-Of-Oxygen.png?resize=1200%2C719&ssl=1)

On The Origins Of Oxygen: ALMA And JWST Characterise The Multi-phase, Metal-enriched, Star-bursting Medium Within A ‘Normal’ z>11 Galaxy
The unexpectedly high abundance of galaxies at z>11 revealed by JWST has sparked a debate on the nature of early galaxies and the physical mechanisms regulating their formation.

MP Mus (PDS 66): You Can’t Judge A star By Its Protoplanetary Disc
In most cases, the material inside a protoplanetary disc condenses to form new planets around the star, leaving large gaps where the gas and dust used to be. These features […]
