Sending a human into space and doing it efficiently presents a galaxy of challenges. Koki Ho, University of Illinois assistant professor in the Department of Aerospace Engineering, and his graduate students, Hao Chen and Bindu Jagannatha, explored ways to integrate the logistics of space travel by looking at a campaign of lunar missions, spacecraft design, and conducting research, published today in the Journal of Spacecraft and Rockets, to create a framework to optimize fuel and other resources.
Researchers at the University of Colorado Boulder have completed an unprecedented 'dissection' of twin galaxies in the final stages of merging. The new study, led by CU Boulder research associate Francisco Müller-Sánchez, explores a galaxy called NGC 6240. While most galaxies in the universe hold only one supermassive black hole at their center, NGC 6240 contains two -- and they're circling each other in the last steps before crashing together.
Southwest Research Institute scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant impact thought to have resulted in the Earth-moon system. Their work shows that an impact between proto-Mars and a dwarf-planet-sized object likely produced the two moons, as detailed in a paper published today in Science Advances.
Theoretical physicists used simulations to explain the unusual readings collected in 2009 by the Mercury Surface, Space Environment, Geochemistry, and Ranging mission. The origin of energetic electrons detected in Mercury's magnetic tail has puzzled scientists. This new study, appearing in Physics of Plasmas, provides a possible solution to how these energetic electrons form.
Researchers at the National Institute of Standards and Technology (NIST) continue to pioneer new antenna measurement methods, this time for future 5G wireless communications systems.
New research published in The Astrophysical Journal examines an interesting light source that was captured by four different telescopes each pointing in a different direction in the sky.
An Earth observation satellite, called TanSat, has produced its first global carbon dioxide maps. TanSat was launched by a collaborative team of researchers in China, and these maps are the first steps for the satellite to provide global carbon dioxide measurements for future climate change research.
This NASA/ESA Hubble Space Telescope image shows a massive galaxy cluster glowing brightly in the darkness.
Researchers from the University of Texas Institute for Geophysics (UTIG) have helped discover the first subglacial lakes ever found in the Canadian High Arctic.
Scientists have decoded faint distortions in the patterns of the universe's earliest light to map huge tubelike structures invisible to our eyes -- known as filaments -- that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.
