A free public lecture 7 p.m. Thursday at the Sam Noble Oklahoma Museum of Natural History, Timberdell Road and Chautauqua Avenue, will provide information about how scientists calculate astronomical ...

For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull. Their precise ...

Our Universe consists of hundreds of billions of galaxies, and for nearby galaxies, distances are mainly measured by classical Cepheids and RR Lyrae (RR Lyr) stars. RR Lyr stars are pulsating variable ...

Let’s try a demonstration that we all enjoyed in elementary school. Close one eye, hold out your thumb at arm’s length, and align it with an object on the other side of the room. Without moving your ...

A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and ...

Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy without a parent star, turning a once purely theoretical class of worlds into a ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Recreation of Baryon Acoustic Oscillations. After a complex statistical analysis of some one million galaxies, a team of researchers at several Chinese universities, and the University of Cordoba was ...

In 1838, Friedrich Wilhelm Bessel won the race to measure the first distance to a star other than our Sun via the trigonometric parallax—setting the first scale of the universe. Recently, Mark Reid ...

We live in a world defined by inches, feet and miles (or centimeters, meters and kilometers, if you prefer), and it’s not difficult for most of us to comprehend sizes and distances given in these ...

The most precise measurement yet of how fast the Universe is expanding shows we have a real and serious problem on our hands.
