Operation Space Station will air on November 5th and 12th, with the first part, High-Risk Build, focusing on the engineering and construction of the ISS. Part two, Science and Survival, will tell the ...

This intimate look at the design, building, and operation of the ISS airs on PBS Nov. 5 and Nov. 12. Celebrating the lasting legacy of our planet's off-world laboratory since it was first inserted ...

In a major scientific breakthrough, researchers have detected a persistent gravitational wave background — subtle ripples in space-time — permeating the universe. This discovery opens a new window ...

Abstract: To compensate the energy loss of traditional passive space-time-coding metasurface, an amplifying space-time-coding metasurface (ASTCM) is proposed in this work. The ASTCM can achieve more ...

When two black holes collide and merge, they release gravitational waves. These waves can be detected by sensitive instruments on Earth, allowing scientists to determine the mass and spin of the black ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

(via PBS Space Time) To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could just physics smarter and build one on a lab ...

Applications have opened for certain Air Force reservists to join the Space Force under its new one-of-a-kind, part-time service model, but advocates for a Space National Guard have pointed out the ...

One of the most important reasons we go to space is to know our own planet better. One of the most important reasons we go to space is to know our own planet better. Today I'm going to tell you about ...

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...
