Still, science being science, we needed proof—and we got it in 1992, when two astronomers found two planets orbiting a pulsar ...

If you were able to catch the last webinar from our Chemical Sciences Roundtable, “Chemistry in 2050– Space” you know that it was out of this world, literally and figuratively. The webinar explored ...

Alex Knapp is a Forbes senior editor covering healthcare and science. The James Webb Space Telescope has its sights set on seven planets circling a red dwarf star called Trappist-1, about 40 ...

Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even habitable. By Carl Zimmer Update, July 29, 2025: The conclusion of this study ...

What are the physics of life? That is more than just a philosophical question—it has practical implications for our search ...

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to ...

A team of astronomers claims to have sniffed out a “biosignature” in the atmosphere of a distant planet called K2-18b. But not everyone agrees that it signals life. An illustration shows what ...

We live in a golden age for space exploration. Scientists are gathering massive amounts of new information and scientific evidence at a record pace. Yet the age-old question remains unanswered: are we ...

Water is essential for life on Earth. So, the liquid must be a requirement for life on other worlds. For decades, scientists’ definition of habitability on other planets has rested on this assumption.

the Earth you walk on today might not be the same planet that was born 4.5 billion years ago. Many scientists believe that in its infancy, Earth collided with another world the size of Mars, and that ...
