SpaceX is requesting permission to launch as many as 1 million satellites into the Earth’s orbit in order to pull off Elon Musk’s latest grand vision of putting data centers in space to do complex computing for artificial intelligence. In a filing with the Federal Communications Commission made on Jan. 30, SpaceX said it’s creating […]
NASA began a two-day practice countdown Saturday leading up to the fueling of its new moon rocket, a crucial test that will determine when four astronauts blast off on a lunar flyby.

Deep in the frozen heart of Antarctica, the South Pole Telescope has been watching one of the most extreme neighborhoods in our galaxy, and it’s just caught something extraordinary happening there. Astronomers have detected powerful stellar flares erupting from stars near the supermassive black hole at the center of the Milky Way. These aren’t your […]
For the first time, scientists have used satellite data to create a 3D map of the sun’s interior magnetic field, the fundamental driver of solar activity. The research, published in The Astrophysical Journal Letters, should enable more accurate predictions of solar cycles and space weather that affects satellites and power grids.

Cosmic radio pulses repeating every few minutes or hours, known as long-period transients, have puzzled astronomers since their discovery in 2022. Our new study, published in Nature Astronomy today, might finally add some clarity.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

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.

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.

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.

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.
