There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on different values depending ...
For the first time, a much younger version of the sun has been caught red-handed blowing bubbles in the galaxy by astronomers using NASA's Chandra X-ray Observatory. The bubble—called an "astrosphere"—completely surrounds ...
Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University researchers now have evidence of the surprisingly simple process that could be responsible for their ...
Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these "dirty snowballs" spend most of their ...
Astronomers have, for the first time, captured a detailed snapshot of planetary systems in an era long shrouded in mystery. The ALMA survey to Resolve exoKuiper belt Substructures (ARKS), using the Atacama Large Millimeter/submillimeter ...
Astronomers using NASA's Hubble Space Telescope have imaged the largest protoplanetary disk ever observed circling a young star. For the first time in visible light, Hubble has revealed the disk is unexpectedly chaotic and ...
The giant planets weren't always where we find them today. Jupiter, Saturn, Uranus and Neptune formed in a more compact configuration and later underwent a violent reshuffling that scattered them to their current positions. ...
Observations with the instrument SPHERE at ESO's Very Large Telescope have produced an unprecedented gallery of "debris disks" in exoplanetary systems.
A vast region of our solar system, called the Kuiper belt, stretches from the orbit of Neptune out to 50 or so astronomical units (AU), where an AU is the distance between Earth and the sun. This region consists mostly of ...
In 1949, famed mathematician and physicist John von Neumann delivered a series of addresses at the University of Illinois, where he introduced the concept of the "universal constructor." The theory was further detailed in ...
