Exoplanet

Of the over 5,000 exoplanets discovered, only about 12 even come close to resembling Earth. That number has been increased with the discovery of Wolf 1069 b, a planet with qualities that make it a good candidate to study further for signs of life.

The James Webb Space Telescope has been used to confirm the existence of an exoplanet for the first time. Known as LHS 475 b, this Earth-sized world is a cosmic stone’s-throw away and is likely the first of many planet discoveries by Webb.

Get Kevin Costner on the phone – astronomers may have found some water worlds. Two nearby planets have been found to be covered in deep global oceans under hot, steamy atmospheres.

The James Webb Space Telescope has provided the most detailed look at an exoplanet atmosphere ever. Studying data from four instruments astronomers compiled a complete molecular and chemical profile of the planet, including signs of active chemistry.

The exoplanets WASP-76 b and WASP-121 b are already known to be peculiar places, but a new discovery has raised even more questions about the composition of the exotic atmospheres around these celestial bodies.

The James Webb Space Telescope has snapped its first direct images of an exoplanet. With its uniquely powerful instruments, Webb captures details that other observatories miss, which will help us understand these distant worlds better.

The James Webb Space Telescope has clearly detected carbon dioxide in the atmosphere of an exoplanet for the first time. The find marks a milestone for the telescope’s goal of analyzing the air of distant planets to aid the search for alien life.

The hunt for planets beyond our solar system has taken off over the last few decades. With the recent discovery of the 5,000th exoplanet coinciding with our own 20th anniversary, now is the perfect time to reflect on the milestones along the way.

The hunt for planets beyond our solar system has now reached a major milestone. A new batch of 65 exoplanets brings the total number of confirmed planets beyond our solar system to over 5,000 – with potentially hundreds of billions left to find.

Ice may seem pretty simple in our everyday experience, but it actually comes in at least 20 different forms. Scientists at UNLV have now discovered a new type of ice that may be found deep in the Earth’s mantle or on distant watery planets.

Astronomers may have detected a new exoplanet around Proxima Centauri, the star closest to our solar system. This tiny new world is one of the lightest ever discovered, which is even more impressive given the technique the team used to find it.

NASA's Chandra X-ray Observatory may have spotted the first exoplanet outside our Milky Way. Located in M51, also known as the Whirlpool Galaxy, the giant exoplanet candidate circles a black hole or neutron star 28 million light years from Earth.
