Astronomers using the 1.2-meter Whipple Observatory to follow the brightness of a lensed galaxy for 14.5 years have calculated that the time delay between light arriving along the shortest and farthest paths is 6.73 years. Plus, DART, Hayabusa2, Juno, fast radio bursts, and This Week in Space History, we look back at NASA’s 1990s attempts to reach Mars.
After six years of Hubble Space Telescope observations and the hypothesis that millions of black holes exist in the Milky Way, scientists have finally found direct evidence for the existence of one such black hole. Plus, planetary formation, a wandering star, and this week in rocket history, we look back at China’s first crewed space station docking.
Researchers using radioactive decay analysis have recreated the early history of some asteroids in our solar system, revealing a more chaotic phase than previously thought. Plus, a near-Earth asteroid, a trove of black holes, and this week in rocket history, we look back at Mercury-Atlas 7.
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.
A ninth-magnitude star in our neighborhood of the Milky Way has been found to contain 65 different elements, including large proportions of heavier elements like gold. This star required either a supernova or a neutron star merger to form. Plus, another solar flare, a strong marsquake, cosmic rays, cookies, and this week in rocket history, we look back at STS-84.
Remember that new object, COW, named for a strange supernova? We’ve seen four more of these Fast Blue Optical Transits, and new research may even have figured out just how and why they occur. Plus, Crew-4 launches, a bunch of planetary science news, micronovae, and this week in rocket history, we look back at the San Marco program.
