Are Titan’s dunes made of comet dust?

A new theory suggests that Titan’s majestic dune fields may have come from outer space. Researchers had always assumed that the sand making up Titan’s dunes was locally made, through erosion or condensed from atmospheric hydrocarbons. But researchers from the University of Colorado want to know: Could it have come from comets?

First curved data link side-steps key 6G wireless challenge

Next-generation wireless signals will no longer emanate indiscriminately from a base station as is the case now but will likely take the form of targeted directional beams. However, any physical interference—an object or a person passing nearby, for example—could interrupt the signal, posing a literal obstacle toward the implementation of ultrafast millimeter-wave and sub-terahertz wireless […]

Researchers investigate three star-forming regions, identify hundreds young stellar objects

Using data from various space telescopes and astronomical surveys, Armenian researchers have investigated three star-forming regions. The study identified hundreds of young stellar objects and provided important information regarding the stellar content of these regions. The new findings were presented in a paper published April 5 in the Astrophysics and Space Science journal.
