Scientists Discover That Volcanoes on Venus Are Still Active
The 3D rendition above shows two coronae observed on the surface of Venus. The ring-like structures are formed when hot material from deep inside the planet rises through the mantle and erupts through the crust. Research by UMD’s Laurent Montesi found that at least 37 coronae on Venus represent recent geologic activity, including the one named Aramaiti, seen on the left in this image. The black line represents a gap in data.

New View of Nature’s Oldest Light Adds Fresh Twist to Debate Over Universe’s Age
The Atacama Cosmology Telescope measures the oldest light in the universe, known as the cosmic microwave background. Using those measurements, scientists can calculate the universe’s age.

Runaway Star Might Explain Black Hole's Disappearing Act
This illustration shows a black hole surrounded by a disk of gas. In the left panel, a streak of debris falls toward the disk. In the right panel, the debris has dispersed some of the gas, causing the corona (the ball of white light above the black hole) to disappear.

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.
