How big is the universe? No one really knows, but since we are in just one Orion spur of the arm of Sagittarius in one galaxy, and there are an unknown number of galaxies, it's big. So big our galaxy…

A new paper uses a combination of cosmic voids – large expanding bubbles of space containing very few galaxies – and the faint imprint of sound waves in the very early Universe, known as baryon…

When a SpaceX crewed Dragon launches atop a Falcon 9 carrying the first astronauts launched from American soil by the United States, they will be making history, setting NASA on a trajectory for the…

The galaxy, named R5519, is 11 billion light-years from our Solar System and it is making stars at a rate 50 times greater than the Milky Way. The hole at its centre is truly massive, with a diameter…

I'm not all that excited about manned missions in space because it is a struggle for NASA to even build a space telescope without going 13 years over budget, but it's worth doing basic research on…

640 light-years away in the constellation of Pisces is a planet where the day side temperature exceeds 4,300 degrees Fahrenheit, hot enough enough to vaporize metal. And it does. Then, on planet…

A new paper reports again about the successful cultivation of red romaine lettuce, Lactuca sativa cv ‘Outredgeous’ plants from surface-sterilized seeds grown in Vegetable Production Systems growth…

The Chang'E-4 mission (CE-4) landed on the eastern floor of the Van Kármán crater, near the Moon's south pole, on Jan. 3, 2019. It deployed its Yutu-2 rover, which uses Lunar Penetrating Radar (LPR)…

NGC 4490, nicknamed the "Cocoon Galaxy" because of its shape, has "a clear double nucleus structure," according to a new paper. It's only realized now because while one nucleus can be seen in optical…

A burst of gravitational waves followed closely by neutrinos and then the light.  While light's speed, in vacuum, is constant in all inertial reference frames, it does vary depending on the…
