A Georgia witness at Woodstock reported watching a large, cylinder-shaped object moving at low altitude, according to testimony in Case 91313 from the Mutual UFO Network (MUFON) witness reporting database.
A trio of researchers at Columbia University has found more evidence showing that sound waves carry mass. In their paper published in the journal Physical Review Letters, Angelo Esposito, Rafael Krichevsky and Alberto Nicolis describe using effective field theory techniques to confirm the results found by a team last year attempting to measure mass carried by sound waves.
Scientists in Japan have “awakened” 28,000-year-old cells from a woolly mammoth that lived on our planet years ago, and their observations could provide a better understanding of extinct animals’ lives.
NASA is considering moving the Orion spacecraft that was to fly on the first Space Launch System mission to a commercial rocket to keep that mission on schedule for mid-2020.
‘Unidentified: Inside America’s UFO Investigation’ will feature new evidence, video footage, plus interviews with former military personnel
Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the solar system, it’s often in rings. Several dust rings circle the Sun. The rings trace the orbits of planets, whose gravity tugs dust into place around the Sun, as it drifts by on its way to the center of the solar system.
In late 2018, the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived at Bennu, the asteroid it will be studying and sampling over the next several years.
For the first time, nanoelectronics have been cooled to below a thousandth of a kelvin
Scientists are rethinking a major milestone in animal evolution, after gaining fresh insights into how life on Earth diversified millions of years ago.
