Discovering new worlds with quantitative spectroscopy

Astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP) and the Vatican Observatory (VO) teamed up to spectroscopically survey more than 1,000 bright stars that potentially host exoplanets.

Four classes of planetary systems

In our solar system, everything seems to be in order: The smaller rocky planets, such as Venus, Earth or Mars, orbit relatively close to our star. The large gas and ice giants, such as Jupiter, Saturn or Neptune, on the other ...

This exoplanet orbits around its star's poles

In 1992, humanity's effort to understand the universe took a significant step forward. That's when astronomers discovered the first exoplanets. They're named Poltergeist (Noisy Ghost) and Phobetor (Frightener), and they orbit ...

Webb detects extremely small main-belt asteroid

A previously unknown 100-to-200-meter asteroid—roughly the size of Rome's Colosseum—has been detected by an international team of European astronomers using the NASA/ESA/CSA James Webb Space Telescope. Their project used ...

Webb telescope catches early galaxy formation in action

Astronomers from the Cosmic Dawn Center have unveiled the nature of the densest region of galaxies seen with the James Webb Space telescope in the early universe. They find it to be likely the progenitor of a massive, Milky ...

Untangling a knot of galaxy clusters

Astronomers have captured a spectacular, ongoing collision between at least three galaxy clusters. Data from NASA's Chandra X-ray Observatory, ESA's (European Space Agency's) XMM-Newton, and a trio of radio telescopes is ...
