The first billion years of the universe was about as chaotic as Tuesday’s first presidential debate. Galaxies were forming, gas was flowing… It was a real time. While we won’t want to look back on Tuesday too often, we do like to look back in time. And, in a cosmic sense, Earth is perfectly positioned to do so. Because of how long it takes light to travel across the universe, our telescopes can pick up the faint signals of what life was like in the universe’s very early days.
On Thursday, astronomers announced the discovery of a massive, intriguing structure from when the universe was just 900 million years old. The structure, about 300 times the size of the Milky Way, contains a supermassive black hole that has ensnared six
The COVID-19 pandemic has fired up interest in outdoor activities in our parks and forests. Now a new UBC study highlights the need to be mindful of how these activities may affect wildlife living in protected areas.
Researchers placed motion-activated cameras on the trails in and around the South Chilcotin Mountains Provincial Park in southwestern B.C., a region popular for its wildlife and recreational activities such as hiking, horseback riding, ATV riding and mountain biking. Overall, they found that environmental factors—like the elevation or the condition of the forest around a camera location—were generally more important than human activity in determining how often wildlife used the trails.
However, there were still significant impacts. Deeper analysis of trail use captured by the cameras showed that all wildlife tended to avoid places that were recently visited by
