Italy from Copernicus Sentinel 3C – ©ESA (released) Two weeks after launching, the European Space Agency’s Copernicus Sentinel 3C satellite has returned its first images of our world in sumptuous color.

NASA’s Curiosity Mars Rover gives us another amazing view of its Gale crater home. Mars is a planetary geologist’s paradise. NASA’s Curiosity rover drove that home recently, with a captivating panorama seen from the slopes of Mount Sharp. The image shows a stunning vista, and was not white-balance adjusted during processing, to show just what a viewer might really see at sunrise standing of Mars.

Milky Way’s first microblazar candidate sits 12,000 light-years away, offering a rare ground-level lab for studying relativistic jetsA black hole 12,000 light-years away is firing a jet of plasma almost directly toward Earth. At that distance, no known or expected danger to Earth has been identified by the researchers or the institutions involved. What astronomers have actually found is rarer and more interesting than a threat. Researchers have identified IRAS 18293-0941 as a compelling candidate for the Milky Way’s first microblazar, a class of object that gives astrophysicists a close-up laboratory for studying some of the most violent physics in the galaxy. What Astronomers FoundThe discovery centers on a binary system whose black hole expels plasma jets at close to three-quarters the speed of light, pointed almost directly toward Earth. The system pairs a hot, massive star with a black hole that completes a full orbit roughly every 11.38 days. Material drawn from the companion star feeds the black hole, and some of that matter gets expelled outward as opposing jets traveling at approximately three-quarters the speed of light. Terminology matters here.
