Many of the moons orbiting Saturn, Uranus and Neptune likely conceal oceans of liquid water beneath miles of icy shell. Because life as we know it needs water, these buried oceans rank among the most promising places to search ...
When the solar system first took up the task of building solid bodies—such as planets, moons and protoplanets—it basically had a choice between two ingredients: heat-forged chondrules, which were millimeter-sized bits of ...
Scientists have discovered a crater on the moon that's bigger than the Roman Colosseum and is the result of a powerful impact two years ago that initially went undetected.
Dwarf galaxies—with a mass equal to about a billion suns, but often considerably less—are the most abundant in the universe. However, because of their low luminosity, they are very difficult to detect. They have mostly been ...
SpaceX announced Tuesday that it was planning to send its flagship rocket, Starship, into orbit, a key step in its project to one day reach the moon or Mars.
Scientists from Trinity College Dublin have developed a way to unravel changing weather patterns on distant worlds. Using this approach, they discovered that the weather on a well-studied brown dwarf, SIMP 0136, previously ...
Most of our experience with the Search for Extraterrestrial Intelligence (SETI) has focused on capturing radio signals that alien species have sent out, whether intentionally or unintentionally. That creates a huge "synchronicity" ...
Have you ever wondered what Earth observation satellites see when they look down at the deep ocean or a dense tropical forest during the dead of night? The answer, for the most part, is nothing. Standard optical sensors require ...
Picture yourself in a manufactured colony that orbits between Earth and the moon. It might sound like science fiction, but it's part of a 2019 presentation made by Jeff Bezos, founder of the space technology company Blue ...
The discovery of water in dark craters at the moon's poles has sparked a "moon rush" to establish bases there, followed by villages, cities and heavy industry. How sustainable is this rush?
