Exoplanet

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.

Astronomers have discovered strange radio signals that could be coming from unseen planets. Models suggest that interactions between the magnetic fields of planets and their host stars produce radio emissions – a new potential way to detect planets.

One Sun is plenty for our solar system, but some planets have been found orbiting two stars at once. Now the ante has been upped again, with evidence emerging of a planet orbiting three stars at once.

In the hunt for extraterrestrial life, most of our attention has been focused on Earth-like worlds. But now, astronomers have defined a new class of exoplanet called “Hycean” worlds that could be a promising place to find signs of life.

Astronomers have captured the first clear images of a colossal moon-forming debris disk orbiting a distant alien planet. According to the authors of the new study, the disk has enough material to create three satellites the size of Earth’s Moon.

Astronomers have counted the number of neutrons inside carbon atoms from 2.8 quadrillion km away. The team managed to measure the ratios of carbon isotopes in the atmosphere of an exoplanet for the first time, which can tell us about how it formed.
