The varied surface suggests a dynamic history, which could include metallic eruptions, asteroid-shaking impacts, and a lost rocky mantle.
The image reveals a glowing, donut-shaped ring at the Milky Way’s heart.
The system is orbited by third stellar companion and may have originated near the center of the Milky Way.
The findings will help scientists trace a black hole’s evolution as it feeds on stellar material.
Named after a goddess of the dawn, the Thesan simulation of the first billion years helps explain how radiation shaped the early universe.
Among thousands of known exoplanets, MIT astronomers flag three that are actually stars.
The planet’s night side likely hosts iron clouds, titanium rain, and winds that dwarf Earth’s jetstream.
A new study shows it’s theoretically possible. The hypothesis could be tested soon with proposed Venus-bound missions.
The discovery, based on an unusual event dubbed “the Cow,” may offer astronomers a new way to spot infant compact objects.
Report led by MIT scientists details a suite of privately-funded missions to hunt for life on Earth's sibling planet.
The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date.
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant.
“In astrophysics, we have only this one universe which we can observe,” the physics professor says. “With a computer, we can create different universes, which we can check.”
