X-ray imaging Archives

Red, green and blue represent Chandra X-ray images of O- (0.6–0.85 keV), Si- (1.76–1.94 keV) and Fe-enhanced (6.54–6.92 keV) regions, respectively. The white grids indicate the fields of view of our two-pointing observations with XRISM/Resolve, which has a 6 × 6 pixel array: a pixel at a corner is only used for calibration. Pixels we selected for our spectral analysis are highlighted in yellow. In the south-east (SE) and north (N) regions, we examined the spectrum of each pixel and selected those exhibiting large equivalent widths of K emission; the spatial distribution of these pixels closely matches that of the O and Si emission lines. In contrast, the west (W) region exhibits weak O line intensity, and the K emission line in its spectrum is faint (Fig. 2).-- Nature

Astrochemistry: Where The Elements Come From

by Keith CowingDecember 4, 2025December 4, 2025

“Why are we here?” is humanity’s most fundamental and persistent question. Tracing the origins of the elements is a direct attempt to answer this at its deepest level. We know […]

Trichogramma cacoeciae wasps imaged in vivo with the BM system. (A) Volume rendering of tomographic data of a first Trichogramma individual inside its parasitized moth egg (Sitotroga cerealella). The egg shell (yellow) was sliced virtually to visualize the wasp (gray) inside the egg. (B)–(D) Phase reconstructed radiograms of a second individual emerging from its host egg (full series in Visualization 2). (E), (F) Flexible movement of mandibles, observed in a third individual (full series in Visualization 3). The arrows indicate that the wasp moves its mandibles independently from each other. - Optica

Tricorder Tech: X-ray Method Enables Micron-resolution Imaging Of Living Organisms Over Long Time Periods

by Keith CowingJuly 9, 2024July 6, 2024

Editor’s note: as we send increasingly sophisticated astrobiology probes – to more places – often at much greater distances – they will need to be able to do more and […]
