New research published by Michigan State University astrophysicists could help scientists answer a century-old question: Where did galactic cosmic rays come from? Go to Source A trio of heliophysicists and satellite trackers at NASA Goddard Space Flight Center and the Goddard Planetary Heliophysics Institute at the University of Maryland has found evidence showing that Starlink satellites reenter Earth’s atmosphere faster during heightened solar activity. For their paper posted on the arXiv preprint server, Denny Oliveira, Eftyhia Zesta and Katherine Garcia-Sage […] Star and planet formation has largely been considered separate, sequential processes. But in a new study, scientists at Southwest Research Institute (SwRI) have modeled a different scenario where planets start developing early—during the final stages of stellar formation—rather than after this phase ends, as previously assumed. The research is published in the journal Nature Communications. […] An international team of astronomers led by the University of Galway has discovered the likely site of a new planet in formation, most likely a gas giant planet up to a few times the mass of Jupiter. Go to Source When astronomers look at distant objects—far away in both space and time—all too often, dust gets in their eyes. Well, not eyes, exactly—in their telescopes’ line of vision. It’s hard to take a close look at a galaxy formed, say, some five billion years ago, because there’s a lot of particulate matter floating in the […] Living in today’s age of ambitious robotic exploration of Mars, with an eventual human mission to the red planet likely to happen one day, it is hard to imagine a time when Mars was a mysterious and unreachable world. And yet, before the invention of the rocket, astronomers who wanted to explore Mars beyond what […] When it comes to helping NASA scientists better understand the effects of space travel on the human body, fruit flies are the heavyweights of experiments in weightlessness. Because humans and fruit flies share a lot of similar genetic code, they squeeze a lot of scientific value into a conveniently small, light package.

He is the second ESA project astronaut from a new generation of Europeans to fly on a commercial human spaceflight mission with Axiom Space. Go to Source Astronomers have conducted very long baseline Interferometry (VLBI) observations of an active galaxy known as Markarian 110. As a result, they detected a relativistic jet in this galaxy. The finding was reported in a research paper published June 4 on the arXiv pre-print server. Go to Source The ongoing search for dark matter, the elusive type of matter that does not emit, absorb or reflect light and is estimated to account for most of the universe’s mass, has not yet yielded conclusive results. Axions, hypothetical elementary particles that were first theorized about in the 1970s, are among the most promising candidates for […] NASA is collaborating with the Alaska Satellite Facility in Fairbanks to create a powerful, web-based tool that will show the movement of land across North America down to less than an inch. The online portal and its underlying dataset unlock a trove of satellite radar measurements that can help anyone identify where and by how […] The core portion of NASA’s Nancy Grace Roman Space Telescope has successfully completed vibration testing, ensuring it will withstand the extreme shaking experienced during launch. Passing this key milestone brings Roman one step closer to helping answer essential questions about the role of dark energy and other cosmic mysteries. Go to Source […] Peggy Whitson has spent nearly two years of her life in space as an Axiom Space employee and former NASA astronaut. Go to Source For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbor. This merger—expected in about 5 billion years—has become a staple of astronomy documentaries, textbooks and popular science writing.

New study puts odds at 50-50It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Go to Source |
