Dr. Leonardos Gkouvelis, researcher at LMU’s University Observatory Munich and member of the ORIGINS Excellence Cluster, has solved a fundamental mathematical problem that had obstructed the interpretation of exoplanet atmospheres for decades. In a paper published in The Astrophysical Journal, Gkouvelis presents the first closed-form analytical theory of transmission spectroscopy that accounts for how atmospheric […] Using data collected by NASA’s Parker Solar Probe during its closest approach to the sun, a University of Arizona-led research team has measured the dynamics and ever-changing “shell” of hot gas from where the solar wind originates. Go to Source New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the maelstrom of interacting magnetic structures around city-sized neutron stars in the moments before they crash. The team identified potential signals emitted during the stars’ final moments that may be detectable by future observatories. Go to Source […] A UBC Okanagan-led research project has given a group of international scientists their clearest view yet of the Milky Way’s magnetic field, revealing that it is far more complex than previously believed. Go to Source The sky is getting crowded. In the last few years, the number of satellite launches has increased by an order of magnitude as mega-constellations of internet-powering hardware crowd into low Earth orbit. The pace of both launching and retiring these units is creating new kinds of pollution, potentially upsetting the climate system and the protective […] Scientists have long relied on tree rings to learn about ancient solar storms—rare bursts of high-energy particles from the sun that can disrupt satellites, power grids, and communication systems across the planet. When these particles hit Earth’s atmosphere, they create a radioactive form of carbon that trees absorb and store in their wood. Go to […] Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe’s mass. While physicists have gathered extensive indirect evidence of its existence, so far dark matter has never been directly observed, thus its composition remains unknown. Go to Source […] Using ESA’s Gaia satellite, astronomers have investigated three open clusters in the galactic disk, namely Berkeley 17, 18 and 39. Results of the new study, published January 21 on the arXiv pre-print server, yield crucial insights into the properties of these stellar groupings. Go to Source The next NASA crew rotation to the International Space Station could launch as early as the morning of February 11, the U.S. space agency said Wednesday. Go to Source Last year, astronomers were fascinated by a runaway asteroid passing through our solar system from somewhere far beyond. It was moving at around 68 kilometers per second, just over double Earth’s speed around the sun. Go to Source NASA’s Artemis II mission will transport four astronauts around the moon, bringing the agency one step closer to sending the first astronauts to Mars. Throughout Artemis II, astronaut voices, images, video, and vital mission data must traverse thousands of miles, carried on signals from NASA’s communications systems. Go to Source SpaceX is targeting a mid-June initial public offering that would coincide with a rare planetary alignment and founder Elon Musk’s birthday, the Financial Times reported on Wednesday, as the billionaire entrepreneur seeks to raise a record $50 billion. Go to Source Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), have led the most extensive observational study to date of runaway massive stars, which includes an analysis of the rotation and […] SpaceX has launched its latest national security mission, yet another GPS satellite that was originally to have been launched by United Launch Alliance. A Falcon 9 that was delayed from Monday because of weather lifted off Tuesday night on the GPS III-9 mission to bring the satellite to medium-Earth orbit from Cape Canaveral Space Force […] The NASA/ESA/CSA James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright galaxy that existed 280 million years after the Big Bang.
