Listen to the 'echoes' of black holes chowing down on stars
(Aurore Simonnet and NASA's Goddard Space Flight Center)
Researchers have detected eight new "echoing" black hole systems in the Milky Way, and they sound like passing through an eerie wind tunnel. And intriguingly, the echoes reveal hints about the role of black holes in galaxy evolution. The gravitational pull of a black hole is so strong that not even light can escape. Black holes are often surrounded by accumulations of superheated gas and dust known as an accretion disk. When a black hole feeds on this material, it produces bursts of bright X-ray light that bounce and echo off the infalling gas.

The hellish planet Venus is known for its incredibly thick atmosphere, crushingly high air pressure and surface temperatures that are hot enough to melt lead. In other words, it has some of the most inhospitable surface conditions in the entire solar system. But going by the standard definition of "habitable zone," Venus sits inside this "Goldilocks" region.

The sample had sat in a freezer for decades at NASA's Johnson Space Center in Houston but recently made its way to the agency's Goddard Space Flight Facility in Maryland, where researchers have begun to examine it. NASA aims for this work to support future lunar sample studies that take place with its new crewed lunar landing program, known as Artemis.

Scientists at Nanjing University believe they can use compounds found in lunar soil to locally produce oxygen and fuel to support crewed moon missions. The team analyzed lunar samples collected by China's Chang'e 5 spacecraft in late 2020 and found that iron-rich and titanium-rich substances present in the moon material could act as a catalyst in a process using sunlight and carbon dioxide.
