This Hubble image shows NGC 6569, a globular cluster located in the constellation of Sagittarius. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Schematic illustration of the quasi-elastic reaction investigated by Duer et al. Top: quasi-elastic scattering of the helium-4 (4He) core from a helium-8 (8He) projectile off a proton target in the laboratory frame. The length of the arrows represents the momentum per nucleon (the velocity) of the incoming and outgoing particles. Zbeam is the beam axis. Bottom: the equivalent p-4He elastic scattering in their center-of-mass frame, where we consider reactions at backward angles close to 180°. In this frame, the momentum of the proton balances that of 4He, Pp=−P4He, that is, the proton is four times faster than 4He. Image credit: Duer et al., doi: 10.1038/s41586-022-04827-6.

The star-filled sky in this Hubble photo lies in the direction of the Galactic center. The light from stars is monitored to see if any change in their apparent brightness is caused by a foreground object drifting in front of them. The warping of space by the interloper would momentarily brighten the appearance of a background star, an effect called gravitational lensing. One such event, OB110462, is shown in the four close-up frames at the bottom. The arrow points to a star that momentarily brightened, as first captured by Hubble in August 2011. This was caused by a foreground black hole drifting in front of the star, along our line of sight. The star brightened and then subsequently faded back to its normal brightness as the black hole passed by. Because a black hole doesn’t emit or reflect light, it cannot be directly observed. But its unique thumbprint on the fabric of space can be measured through these so-called microlensing events. Image credit: NASA / ESA / Hubble / K. Sahu, STScI / J. DePasquale, STScI.

This Hubble image shows the globular cluster Terzan 9, a relic of a generation of long-lived stars that formed in the early Galaxy. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
