In a first, astronomers watch a black hole’s corona disappear, then reappear
This diagram shows how a shifting feature, called a corona, can create a flare of X-rays around a black hole. The corona (feature represented in purplish colors) gathers inward (left), becoming brighter, before shooting away from the black hole (middle and right). Astronomers don't know why the coronas shift, but they have learned that this process leads to a brightening of X-ray light that can be observed by telescopes.

Charm Quarks Offer Clues to Confinement
A collision of gold nuclei recorded by the Berkeley Lab-built Heavy Flavor Tracker (HFT), a component of the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The white points show “hits” recorded by particles emerging from the collision as they strike sensors in three layers of the HFT. Scientists use the hits to reconstruct charged particle tracks (red and green lines) to measure the relative abundance of certain kinds of particles emerging from the collision – in this case, charmed lambda particles.

Two Bizarre Brown Dwarfs Found With Citizen Scientists' Help
This artist's concept shows a brown dwarf, a ball of gas not massive enough to power itself the way stars do. Despite their name, brown dwarfs would appear magenta or orange-red to the human eye if seen close up.

NASA’s Parker Solar Probe Spies Newly Discovered Comet NEOWISE
An unprocessed image from the WISPR instrument on board NASA’s Parker Solar Probe shows comet NEOWISE on July 5, 2020, shortly after its closest approach to the Sun. The Sun is out of frame to the left. The faint grid pattern near the center of the image is an artifact of the way the image is created. The small black structure near the lower left of the image is caused by a grain of dust resting on the imager’s lens.

Conditions Ripe for Active Amazon Fire, Atlantic Hurrican Seasons
On August 11, 2019, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured these images of several fires burning in the states of Rondônia, Amazonas, Pará, and Mato Grosso. This year’s drought combined with the recent uptick in deforestation make these states particularly vulnerable this fire season to fires that can grow out of control and spread.
