“They say great discoveries often start with someone saying “Huh, that’s weird,” observes Tyce DeYoung, a member of the IceCube and HAWC collaborations, two large international groups of physicists who are building and operating experiments to detect the highest energy particles in the Universe in an email to The Daily Galaxy. “But unfortunately, most of the time we say “That’s weird” it really is just some everyday weirdness, not a great discovery.”
Traveling near the speed of light: an unprecedented new radio-telescope telescope image of the Milky Way Galaxy’s turbulent center has revealed nearly 1,000 mysterious magnetic filaments shown below stretching up to 150 light years long. The one-dimensional strands are found in pairs and clusters, often stacked equally spaced, side by side like strings on a harp. “These filaments have been a mystery for several decades, and this study shows the substantial impact that MeerKAT is having in our studies of the center of our galaxy, and of these objects in particular,” Craig Heinke, professor of physics at the University of Alberta, wrote in an email to The Daily Galaxy.
“We did not expect that Spitzer, with a mirror no larger than a Hula-Hoop, would be capable of seeing galaxies so close to the dawn of time,” said Michael Werner, Spitzer’s project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California in 2019. “But nature is full of surprises, and the unexpected brightness of these early galaxies, together with Spitzer’s superb performance, puts them within range of our small but powerful observatory.”
Today, January 24, 2022 at around 2:05 p.m. Eastern time, NASA engineers confirmed that the James Webb Space Telescope successfully reached its final destination called the second Lagrange Point or L2, where Webb telescope will be orbiting around the sun alongside Earth in a small pocket of stability where the gravitational forces of the sun and Earth blend.
Our very strange Universe delivered its usual fascinating news stories over the past few days, ranging from Evolution Tells Us We Might Be the Only Intelligent Life in the Universe to How James Webb will reveal what Hubble missed.
Another week of amazing news from our Pale Blue Dot, with stories ranging from Earth Is Tiny Because The Sun Had Saturn-Like Rings Before It Had Planets to How Can Something So Small Live So Long.
The heaviest natural elements on the periodic table such as gold, platinum, and uranium were forged during the mergers of binary neutron stars. Astronomers have previously estimated that tens of thousands of such binary neutron star mergers must have occurred throughout our Milky Way Galaxy during the past 10 billion years, sprinkling neutron-rich elements throughout the gas that eventually formed the next generation of stars and planets. By studying the composition of meteorites, astronomers now conclude that a single collision of neutron stars occurred shortly before and near to the formation of our solar system, producing a measurable fraction of the heavy elements here on Earth.
