One oceans worth of water destroyed in planetary nursery every month, say researchers

An international team of astrophysicists, including from London, Ont.’s Western University, are using the James Webb Space Telescope to reveal the destruction of one oceans’ worth of water every month in a planetary nursery in the Orion Nebula.

Evidence for heavy-seed origin of early supermassive black holes from a z ≈ 10 X-ray quasar

Observations of quasars reveal that many supermassive black holes (BHs) were in place less than 700 Myr after the Big Bang. However, the origin of the first BHs remains a mystery. Seeds of the first BHs are postulated to be either light (that is, 10−100 M⊙), remnants of the first stars, or heavy (that is, 10−105 M⊙), originating from the direct collapse of gas clouds. Here, harnessing recent data from the Chandra X-ray Observatory, we report the detection of an X-ray-luminous massive BH in a gravitationally lensed galaxy identified by the James Webb Space Telescope at redshift z ≈ 10.3 behind the cluster lens Abell 2744. This heavily obscured quasar with a bolometric luminosity of ~5 × 1045 erg s−1 harbours an ~107−108 M⊙ BH assuming accretion at the Eddington limit. This mass is comparable to the inferred stellar mass of its host galaxy, in contrast to what is found in the
