Animation of the findings by researchers who used time-delay cosmography to independently confirm that the universe’s current ...

Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and ...

Dense gas clumps from the time of the formation of the first stars in the Universe should affect the average intensity of radio waves on the sky. Numerical simulations show that this offers a new way ...

When people talk about baking, they often focus on the final product. The tender cookies, the domed muffins, the rich brownies. But the real draw of baking starts long before you roll out the pie ...

With the theme 'Shaping the future', Alexander Gerst used the special conditions of space, such as microgravity, in addition to his operational tasks on board the International Space Station (ISS), to ...

The purpose of the APS graduate program is to teach the techniques for outstanding research. Graduate students are generally supported on Research Assistantships (RAs) after their first year. As an RA ...

Columbia News produces a monthly newsletter (subscribe here!) and article series featuring a roundup of awards and milestones that Columbia faculty, staff, and students have received in recent days.

This course provides an introduction to different astrophysical subjects with focus on the underlying physical processes, solving problems numerically, data analysis, scientific writing and methods ...

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg, and Haudenosaunee peoples. Our main campus is situated on the ...

We use lasers almost everywhere in our daily lives—from hand-held pointers, laser printers, and barcode scanners to LIDAR, LASIK, and fiber optic telecommunications networks. But did you know that the ...

Stars are often gregarious things. Based on observation and theoretical models, many stars are born in clusters — groups of ten or more stars that were formed from the same interstellar cloud. The ...
