A team of astronomers led by Penn State has discovered that planet-forming materials can survive and persist even in some of the most extreme environments in our galaxy.
NASA’s Europa Clipper spacecraft, launched on October 14, 2024, has reached a significant milestone as one of its key scientific instruments, the Ultraviolet Spectrograph (UVS), completed initial commissioning.
Galactic turbulence, a cosmic enigma influencing everything from star formation to particle movement, has been simulated with unprecedented precision. The surprising results challenge long-held theories about energy flow in the vast interstellar medium.
Scientists have identified a mysterious X-ray source, known as AX J145732−590 located far beyond our own Milky Way. Observations using X-ray telescopes suggest this object, previously hidden by the dense material within our galaxy, is a large collection of galaxies.
An international study has revealed that super-Earth exoplanets, planets larger than Earth but smaller than gas giants like Neptune, are significantly more common across the universe than scientists once believed.
As artificial intelligence helps scientists push the boundaries of how we observe the universe, researchers have developed an AI system capable of designing entirely new types of detectors for observing gravitational waves.
Recent moves in the European Commission include the European Commission and the Government of Ukraine, which have signed a new agreement allowing Ukraine to participate in key components of the European Union Space Programme.
It's not uncommon to spot at least one bright planet on most nights; however, sometimes, you may get the chance to see up to four of five planets visible at once. This creates a "planetary parade" or a "planet alignment".
![Figure 1 - The figure illustrates the diversity and multi-scale nature of the structures in the Galaxy. The first two lines are real astronomical images, which go from the galactic disk itself and down to the planet-forming disks. The last two lines are generated from numerical simulations and aim to understand and interpret the observations.
