Clouds, hellish temperatures, endless nights? Characterizing the atmosphere of exoplanets, planets that orbit stars other than the sun, is a formidable task.

Most of what we know about planets outside our Solar System relates to gas-giant planets. A new study has identified and characterised a smaller exoplanet.

AI loves to cheat, but new research shows it doesn’t do so when analysing the atmospheres of exoplanets.

On the ultra-hot exoplanet WASP-76b, metal is vaporized in the heat. Studying the atmosphere of extreme planets will reveal more wild and weird weather.

Astronomers hunting extraterrestrials were excited to discover an intriguing signal, but closer inspection has revealed it wasn’t aliens.

In 5 billion years the Sun will collapse. A new discovery suggest some planets may still survive afterwards.

For the first time ever, astronomers have astrophysical evidence that Jupiter and many other planets will survive the death of the Sun.
Astronomers have found a way to estimate the number of stars in the universe.

Scientists have a good estimate on the staggering number of stars in the universe.
The James Webb Space Telescope is the biggest orbital telescope ever built and is scheduled to be launched into space on Dec. 18, 2021.

The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.

By studying the chemical makeup of binary stars, astronomers found many planetary systems are far less peaceful than ours.

Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?

Weather on other planets and moons can be much more extreme than on Earth.
Proxima Centauri is the closest star to the solar system and is home to a potentially habitable planet.

Astronomers just measured the largest flare ever from Proxima Centauri, humanity’s closest neighboring star. These flares could be bad news for life trying to develop on a planet orbiting the star.
A planet in a triple-star system has been discovered.

Publicly available data and collaborations between scientists have led to the discovery of a planet in a triple-star system.

This discovery will shape the hunt for life on exoplanets.
In the future, robots we’ve programmed may evolve and multiply on distant planets.

The robots are ‘born’ via 3D printer, and recycle themselves upon their ‘death’.

I simulated the climate on 100,000 exoplanets to find out.
