Happy 32nd Birthday to Hubble! Celebrates NASA –“We’re celebrating the Hubble Space Telescope’s 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called The Hickson Compact Group 40. This eclectic, merging galaxy grouping includes three spiral-shaped galaxies, a giant elliptical galaxy, and a lenticular (lens-like) galaxy. Somehow, these different galaxies crossed paths in their evolution to create an exceptionally crowded and eclectic galaxy sampler held together by a cloud of dark matter. Observations suggest that such tight groups may have been more abundant in the early universe and provided fuel for powering black holes, known as quasars.”
“Ceres –the only dwarf planet in the inner Solar System–has gained a pivotal role in assessing the origin, evolution and distribution of organic species across the inner solar system,” said Southwest Research Institute scientist Simone Marchi, about high abundance of carbon on Ceres’ near surface, which could be due to an excess of organic matter, possibly formed locally due to water-rocks chemistry.”
Today’s stories range from Isaac Asimov: The biochemist who created new worlds to Scientists Investigate Supermassive Black Hole Ancestor from Universe’s ‘Cosmic Dawn’ to Astronomers and an Astronaut to Reveal their Favorite Worlds Orbiting Distant Stars, and much more. “The Galaxy Report” brings you news of space and science that has the capacity to provide clues to the mystery of our existence and adds a much needed cosmic perspective in our current Anthropocene Epoch.
“This group of asteroids we hypothesized is probably about 1000-times less well populated than the asteroid belt,” NASA astrophysicist Marc Kuchner at the Goddard Space Flight Center, Exoplanets and Stellar Astrophysics Laboratory, told The Daily Galaxy about a group of 10,000 asteroids discovered co-orbiting the Sun with Venus. “We don’t know if they were all produced in one big break-up event. But if this group is like the main asteroid belt, there probably were some recent breakups in the last few million years that have left their imprint on the dust cloud. By the way…some of these objects will probably work their way into orbits that cross the Earth’s orbit, and become near-Earth asteroids.”
“Understanding how Earth regulates climate both in the modern era but also in the distant past is critical for our understanding of planetary habitability,” said Noah Planavsky, a biogeochemist at Yale University. “This will help guide our search for life beyond our solar system and is an example of how the evolution of complex life fundamentally changed our planet.”
Our Pale Blue Dot has produced a wealth of fascinating new stories the past few days –from when Earth had two moons to a major discovery in Antarctica’s seas.
