Searching for habitable exoplanets will require decades of work, new technologies, and new ideas. A lot of that effort seems to coalescing around the Habitable Worlds Observatory (HWO), a proposed
Macquarie University astronomers have tracked an extreme planet’s orbital decay, confirming it is spiraling toward its star in a cosmic death dance that could end in three possible ways. It
Atmospheric escape shapes an exoplanet’s future. Earth’s exosphere is extended and detectable due to ocean-related atmospheric escape. If we can detect the same features on an exoplanet, it could suggest
When we leave Earth, we have to bring everything with us, from the air we breathe to the food we eat. For example, a 6-person, 1000-day mission might require 108
Very massive stars (VMSs)have had a massive impact on the formation of our universe. However, there aren’t very many of them, with only around 20 known specimens in the Milky
Our quest for universal internet is stealing the stars. Thousands of satellites now travelling across the night sky are far brighter than international safety limits, turning what was once humanity’s
Alone among known planets, Earth has vast oceans on its surface and its landmasses are marked with lakes and extensive river drainage systems. Water is the biosphere’s lifeblood, and without
A new method to analyze gravitational-wave data could transform how we study some of the universe’s most extreme events—black holes smashing into each other.
Our circumstances here on the wondrous, life-supporting Earth can give us a false understanding of what the universe is really like. But our blue-skied, temperate planet is the extreme exception
