Saturday Citations: Listening to bird dreams, securing qubits, imagining impossible billiards

It's Saturday, which means that in a universe where the arrow of time moves backward, people have to go to work tomorrow. In such a hypothetical universe, Garfield hates Fridays—tough to imagine. This week, we looked at ...

Measuring the atmospheres of other worlds to see if there are enough nutrients for life

Life on Earth depends on six critical elements: carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur. These elements are referred to as CHNOPS, and along with several trace micronutrients and liquid water, they're ...

Researchers reveal faint features in galaxy NGC 5728 though JWST image techniques

Mason Leist is working remotely—127 million light-years from Earth—on images of a supermassive black hole in his office at the UTSA Department of Physics and Astronomy.

Communicating with a relativistic spacecraft gets pretty weird

Someday, in the not-too-distant future, humans may send robotic probes to explore nearby star systems. These robot explorers will likely take the form of lightsails and wafercraft (a la Breakthrough Starshot) that will rely ...

Aerocapture is a 'free lunch' in space exploration

When spacecraft return to Earth, they don't need to shed all their velocity by firing retro-rockets. Instead, they use the atmosphere as a brake to slow down for a soft landing. Every planet in the solar system except Mercury ...

Satellites make up to 80,000 flashing glints per hour. It's a big problem for astronomers

Large-scale sky surveys are set to revolutionize astronomy. Observatories such as Vera Rubin and others will allow astronomers to observe how the sky changes on the scale of days, not weeks or months. They will be able to ...
