A survey of 93 quasars spread out over billions of light years shows the supermassive black holes in their cores are spinning in alignment, a hint that current models of the universe may be missing key data. Continue reading â†’
Astronomers have a conundrum on their hands. When they count up all of the ultraviolet light their calculations say SHOULD be in the universe, they come up way short! There's more such light than we can account for. What gives?
There's nothing in the universe that isn't moving -- even us. Trace tries to slow things down long enough to calculate just how fast we little humans, even when seated, are flying through space.
Trace breaks down some of his favorite theories for what the universe is. Are we really just living in a computer simulation?
The "lithium problem" has been a quandary for astronomers for decades, but now, with the help of one of the world's most powerful observatories, we've discovered that the puzzle isn't exclusive to stars inside the Milky Way. Continue reading â†’
Chemical signature of ancient star suggests it incorporated material blasted into space by a supernova explosion from huge star in early universe.
The idea that there are an infinite number of universes beyond our own is assumed impossible to prove or disprove -- but a new computer model might give us hints as to what evidence to look for. Continue reading â†’
A strange geometric shape observed on a faraway world. Haven't we seen this movie before? Thankfully, it turns out the shape is likely a product of nature and not the ghost of Stanley Kubrick. Ian O'Neill explains.
