UCLA astronomers have identified 366 new exoplanets, thanks in large part to an algorithm developed by a UCLA postdoctoral scholar.

Scientists have added a whopping 301 newly confirmed exoplanets to the total exoplanet tally.

Detailed atmospheric studies will provide key insights into some of the most common - and mysterious - planets known in the galaxy.

When it comes to directly imaging Earth-like exoplanets orbiting faraway stars, seeing isn't always believing.

Planetary systems take millions of years to form, which introduces quite a challenge for astronomers.

Using radio data from the ALMA observatory and physical modelling, astronomers led by Kamber Schwarz (Max Planck Institute for Astronomy and University of Arizona) have managed to determine the mass of a potential "planet factory," the protoplanetary disk around the star GM Aurigae.

Tantalising evidence has been uncovered for a mysterious population of "free-floating" planets, planets that may be alone in deep space, unbound to any host star.

At night, seven-year-old Miguel likes talking to his father Cesar Rubio about planets and stars. "I try to nurture that," says Rubio, a machinist in Pomona, California, who makes parts for mining and power generation equipment.

Despite numerous attempts, no exomoon has firmly been confirmed to date. New missions like CHEOPS aim to characterize previously detected exoplanets, and potentially to discover exomoons.

A New Way Of Forming Planets

In the last 25 years, scientists have discovered over 4000 planets beyond the borders of our solar system.

Remnants of planets with Earth-like crusts have been discovered in the atmospheres of four nearby white dwarf stars by University of Warwick astronomers, offering a glimpse of the planets that may have once orbited them up to billions of years ago.

An international team of researchers led by the National Centre of Competence in Research Planet of the University of Bern and the University of Geneva studied the atmosphere of the ultra-hot exoplanet WASP-121b.

Eight months after the space telescope CHEOPS started its journey into space, the first scientific publication using data from CHEOPS has been issued.

A team of astronomers have identified the first direct evidence that groups of stars can tear apart their planet-forming disc, leaving it warped and with tilted rings.

The nearest exoplanets to us provide the best opportunities for detailed study, including searching for evidence of life outside the Solar System.

Observations made with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed the telltale signs of a star system being born.

NASA's planet-hunting TESS Mission keeps giving astronomers new realities to examine and explain.

When Exoplanets Collide

A dramatic glimpse of the aftermath of a collision between two exoplanets is giving scientists a view of what can happen when planets crash into each other. A similar event in our own solar system may have formed the moon.

Using Earth's most powerful array of radio telescopes, astronomers have made the first observations of a circumplanetary disk of gas and dust like the one that is believed to have birthed the moons of Jupiter.
