Researchers have found that elusive intermediate-mass black holes can form in dense star clusters containing anywhere from tens of thousands to millions of tightly packed stars called “globular clusters.” An intermediate-mass black hole has a mass between 100 and 10,000 suns. They are heavier than solar-mass black holes, which have a mass range between 10 … Read more
The early universe contained far fewer miniatures black holes than previously thought, making the origin of our cosmos’ missing matter an even greater mystery, a new study suggests. Miniature or primordial black holes (PBHs) are black holes thought to have formed in the first fractions of a second after the Big Bang. According to leading … Read more
Artist’s concept of a previously proposed possible planet, HD 26965 b – is often compared to the fictional “Vulcan” in the Star Trek universe. Credit: JPL-Caltech New research refutes the existence of Vulcan, a planet thought to orbit 40 Eridani A, attributing the detected signals to the surface activity of the star. A planet thought … Read more

OSIRIS-APEX emerged “unscathed” from its closest brush ever with our sun on January 2, scientists announced on Tuesday (May 28). The probe, originally known as OSIRIS-RExcompleted its sample return mission to asteroid Bennu and is now heading for the space rock Apophis on an extended mission. This new mission calls for OSIRIS-APEX to slide 25 … Read more

The James Webb Space Telescope (JWST) has discovered not one, but two of the earliest and most distant galaxies ever seen, continuing to break the records it previously set. The most distant galaxy, JADES-GS-z14-0, is seen as it was about 300 million years after the Big Bang, existing at least 100 million years earlier than … Read more
When people think about the dangers of climate change, the idea of sudden changes is very scary. Movies like The Day After Tomorrow feed into that fear, with visions of unimaginable storms and populations fleeing rapidly changing temperatures. While Hollywood clearly takes liberties with the speed and magnitude of disasters, several recent studies have raised … Read more
Space flight doesn’t usually come to mind when you think of the quiet, green mountains of North Carolina. It is true that, in the early 1960s, NASA built the (now defunct) Rosman Satellite Tracking and Data Acquisition facility among the rolling hills of Appalachia to track Soviet satellites and relay communications for the Gemini and … Read more

A new paper that takes a look at the Fermi Paradox using the Drake Equations has suggested an uncomfortable solution: maybe we’re alone in the galaxy. If you haven’t heard of the Fermi Paradox, it goes something like this: given the infinity of the universe and the implied probability of life evolving elsewhere, how is … Read more
After its “birth” in the Big Bang, the universe consisted mostly of hydrogen and a few helium atoms. These are the lightest elements on the periodic table. More or less all elements heavier than helium were produced in the 13.8 billion years between the Big Bang and the present day. Stars have produced many of … Read more
