Over the past three decades, astronomers around the world have been using the observations of the Hubble Space Telescope to more precisely calculate the expansion of the universe. And they have converged on a precision of just over 1%. Plus, Boeing launches Starliner, Voyager 1 struggles, and Erik reviews his favorite camera lens.
With a groundbreaking technique, astronomers have used a galaxy as a gravitational lens to backlight two hydrogen clouds, peering back 11 billion light-years at our early universe. Plus, volcano water on the Moon, a quadruple star system, and this week’s What’s Up takes a careful look at the Sun.
A forensic analysis of the element concentration found in the Hypatia stone finds evidence in the cometary fragment, which may have impacted Earth 28 million years ago, of a supernova origin story. Plus, Ceres, Mars, and this week in rocket history, we look back at SpaceX’s COTS Demo Flight 2.
Using a mere twelve grams of lunar soil returned by the Apollo missions, scientists have successfully grown plants in the lab. With a wealth of genetic data on hand, they can now analyze the changes to the plants and the soil. Plus, stellar cannibalism, a black hole merger, brown dwarfs, water on Mars, and a review of “Star Trek: Strange New Worlds”.
Data from the Hubble Space Telescope has determined that the newly discovered companion of a star that went supernova had its outer hydrogen layer siphoned off before the explosion. The results support the theory that massive stars generally form and evolve as binary systems. Plus, rocks from space, Crew-4 comes home, searching for life beyond Earth, and another Canon lens review.
Using spherical grains called ooids, found on Earth in shallow, tropical waters, scientists have found a possible mechanism for the formation of hydrocarbon sand on Titan. Plus, rocket launches, Jupiter and Mars, space explosions, and this week in rocket history, we look back at Britain’s Ariel satellite program.
