How many exoplanets are there? Not that long ago, we didn’t know if there were any. Then we detected a few around pulsars. Then the Kepler spacecraft was launched and it discovered a couple thousand more. Now NASA’s TESS (Transiting Exoplanet Survey Satellite) is operational, and a new study predicts its findings.
We have comets and asteroids to thank for Earth’s water, according to the most widely-held theory among scientists. But it’s not that cut-and-dried. It’s still a bit of a mystery, and a new study suggests that not all of Earth’s water was delivered to our planet that way.
A highly effective (but very difficult) method of exoplanet detection involves capturing direct images of bodies orbiting distant stars from their reflected light or heat signatures.
A new NASA-led study shows that Proxima b could support the existence of an ocean on its dayside, which means it could still be habitable.
According to a new study by a pair of researchers, planets covered in deep oceans (aka. “water worlds”) may be more habitable than previously thought.
According to a new study by an international team of researchers, a good way to look for signs on life on exoplanets would be toe examine the ejected material of asteroid impacts.
According to a new study from the Earth-Life Science Institute, it may be time to fine-tune what astronomers mean by “habitable zone”
According to a new study by a team of Columbia University’s Cool Worlds Lab, one of the TRAPPIST-1 planets had a large iron core, which could have immense implications for its habitability.
A new study has cast doubt on whether or not the TRAPPIST-1 system could be habitable, indicating that it has too much water to support life
The Gravitational Microlensing method relies on rare events (one star passing in front of another) to focus light and search for exoplanets.
