Downloading NASA's dark matter data from above the clouds      (via sciencedaily.com)     Original source 

Data from a NASA mission to map dark matter around galaxy clusters has been saved by a new recovery system. The system allowed the retrieval of gigabytes of information, even after communication failed and the balloon-based telescope was damaged in the landing process.

'Bouncing' comets could deliver building blocks for life to exoplanets      (via sciencedaily.com)     Original source 

How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar building blocks to other planets in the galaxy.

Galactic 'lightsabers': Answering longstanding questions about jets from black holes      (via sciencedaily.com)     Original source 

The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that energy close to the event horizon of black hole M87* is pushing outward, not inward. The researchers have also created a way to test the prediction that black holes lose rotational energy and to establish it's that energy that produces the incredibly powerful jets.

Some of today's earthquakes may be aftershocks from quakes in the 1800s      (via sciencedaily.com)     Original source 

In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.

Tracking down quantum flickering of the vacuum      (via sciencedaily.com)     Original source 

Absolutely empty -- that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations. Experts are currently preparing a laser experiment intended to verify these vacuum fluctuations in a novel way, which could potentially provide clues to new laws in physics. A research team has developed a series of proposals designed to help conduct the experiment more effectively -- thus increasing the chances of success.

Exploring the origin of nucleosynthetic isotope variations in Ryugu samples      (via sciencedaily.com)     Original source 

The observed variations in chromium (Cr) isotope ratios in the Ryugu asteroid samples collected by Hayabusa2 likely resulted from elemental redistribution of slightly soluble Cr by water within the parent body, reveals a multinational study. The results provide useful insights for expanding our understanding of the origin and evolution of materials in our solar system.

Mystery resolved: Black hole feeding and feedback at the center of an active galaxy      (via sciencedaily.com)     Original source 

Almost every large galaxy has a supermassive black hole at its center. An international research team has recently observed the Circinus galaxy, which is one of the closest galaxies to the Milky Way, with high enough resolution to gain further insights into the gas flows to and from the black hole at its galactic nucleus.

Black holes are messy eaters      (via sciencedaily.com)     Original source 

New observations down to light-year scale of the gas flows around a supermassive black hole have successfully detected dense gas inflows and shown that only a small portion (about 3 percent) of the gas flowing towards the black hole is eaten by the black hole. The remainder is ejected and recycled back into the host galaxy.

Exploding stars      (via sciencedaily.com)     Original source 

When massive stars or other stellar objects explode in the Earth's cosmic neighborhood, ejected debris can also reach our solar system. Traces of such events are found on Earth or the Moon and can be detected using accelerator mass spectrometry, or AMS for short.
