Amazing: JWST spotted a naked black hole, 50 million times as massive as the Sun, in the very early universe. This is strong evidence that some black-hole "seeds" formed before their galaxies--a big shift in our view of how the cosmos evolved after the Big Bang. 🧪🔭 esawebb.org/news/weic2609/
An image detail from Webb’s NIRCam shows the Little Red Dot Abell2744-QSO1, gravitationally lensed by Abell 2744, an enormous mega-cluster of galaxies also known as Pandora’s Cluster.

Pulled out to the right is a map showing the speed that gas is moving toward or away from the telescope (rotational velocity) in different parts of QSO1. The map was made with data collected using NIRSpec’s integral field unit (IFU), a combination of camera and spectrograph. The IFU gathers an image along with 900 spectra from a square patch of sky 3 arcseconds by 3 arcseconds, creating maps showing differences in brightness of thousands of wavelengths between 0.6-micron and 5.3-micron light across the object. The gas velocity is calculated based on Doppler shift: the colours are shifted slightly toward shorter (bluer) wavelengths where material is moving toward us, and longer (redder) wavelengths where it is moving away.

The Webb data shows that the glowing gas has Keplerian rotation: it is orbiting a central point in the same way that planets orbit a star. This means that most of the mass of QSO1 must reside in a single point in the centre, i.e., a black hole. Because the velocity of the orbiting gas follows very simple laws of gravity, the data can then be used to calculate the mass of the black hole: It appears to be 50 million solar masses, or 50 million times the mass of our Sun. This is about two-thirds of the entire mass of QSO1.

Artemis 2 image of a solar eclipse by the Moon. Saturn (nearest to the Moon), Mars and Mercury (farthest) are in a line to the lower right of the Moon. I've drawn a red box to highlight the region another image zoomed into. The box contains Saturn, Mars, and even Neptune.This image zoomed in to the area of sky containing Saturn on the left and Mars on the right. Between them I've drawn a yellow circle. In the middle of the circle is a faint spec of light visible just above the image noise. It lies at the location of Neptune.A Stellarium view of the sky at the time of the Artemis 2 solar eclipse photo. The view shows the sky from Earth, but the relative locations of the planets and stars from the vantage point of Artemis 2 will be identical at the resolution of the image. The location of Neptune is indicated between Saturn and Mars.
