Analysis of 6,594 solar twins from Gaia data suggests a mass migration of sun-like stars from the inner regions of the Milky Way, perhaps at a time when the galaxy's central pole was still forming.

Something is ticking near the Milky Way's supermassive black hole

A sensitive radio survey by Breakthrough Listen has identified a candidate millisecond pulsar near Sagittarius A*, the supermassive black hole at the center of the galaxy. If confirmed, the finding could enable unprecedented tests of general relativity.
This image shows the **Central Molecular Zone (CMZ)** at the heart of the Milky Way — a region rich in dense, complex gas clouds — as mapped by **ALMA** as part of the **ACES** survey. The inset image shows the ACES simulation in which different molecules are marked with different colors. This is the largest mapping ever made by ALMA, spanning an angular span of about three full moons side by side in the sky. (Credit: ALMA ‏(ESO/NAOJ/NRAO) /‏ S. Longmore et al.; Background: ESO /‏ D.

The simulations have also revealed candidates for a new celestial body – “globular cluster dwarfs” – that may have been hidden for a long time.

This collage shows a small selection of regions of the Milky Way captured as part of a map created from the most detailed infrared wavelength imaging of our galaxy. Here you can see, from left to right and from top to bottom: NGC 3576, NGC 6357, Messia 17, NGC 6188, Messia 22 and NGC 3603. All are clouds of gas and dust in which stars are formed, with the exception of Messia 22, which is a very dense group of ancient stars. Photo: European Southern Observatory ESO

Image: Horsehead Nebula (NASA Webb NIRCam): This image of the Horsehead Nebula, taken by NASA's James Webb Space Telescope, focuses on a portion of the "Horse's Mane" that is about 0.8 light-years across. It was taken using a camera Webb's NIRCam (near-infrared camera) The airy clouds at the bottom of the image are dominated by cold molecular hydrogen. Red streaks extending above the main nebula represent mostly atomic hydrogen gas in this region, known as the photodissociation region and from nearby masses creates a mostly neutral region of gas and dust between the fully ionized gas above and the cooler nebula below. As in many Webb images, distant galaxies are scattered in the background. This image consists of light at wavelengths of 1.4 and 2.5 microns (shown in blue), 3.0 and -3.23 µm (cyan), 3.35 µm (green), 4.3 µm (yellow), and 4.7 and 4.05 µm (red). Credit: NASA, ESA, CSA, K.
