A New Way Of Forming Planets

Mars Imaged by Hubble

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

High Schoolers Discover Four Exoplanets

CHEOPS Finds A Unique Planetary System

Musical notes that sound pleasant together can form a harmony. These notes are usually in a special relationship with each other: when expressed as frequencies, their ratios result in simple fractions, such as four-thirds or three-halves.

A 'Super-puff' Planet Like No Other

The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found.

Maunakea Telescopes Confirm First Brown Dwarf Discovered By Radio Observations

A collaboration between the LOw Frequency ARray (LOFAR) radio telescope in Europe, the Gemini North telescope, and the NASA InfraRed Telescope Facility (IRTF), both on Maunakea in Hawai'i, has led to the first direct discovery of a cold brown dwarf from its radio wavelength emission.

An Earth-sized Rogue Planet Discovered In The Milky Way

Our Galaxy may be teeming with rogue planets, gravitationally unbound to any star. An international team of scientists, led by Polish astronomers, has announced the discovery of the smallest Earth-sized free-floating planet found to date.

Vaporized Metal In The Atmosphere Of An Exoplanet

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.

Stars And Planets May Be Siblings

An international team of scientists has discovered planet formation in a star system younger than 500,000 years old.

Astronomers Discover An Earth-sized "pi planet" With A 3.14-day Orbit

In a delightful alignment of astronomy and mathematics, scientists at MIT and elsewhere have discovered a "pi Earth" -- an Earth-sized planet that zips around its star every 3.14 days, in an orbit reminiscent of the universal mathematics constant.

Carbon-rich Exoplanets May Be Made Of Diamonds

As missions like NASA's Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of, and if they could be habitable or even inhabited.

ALMA Captures A Stirred-up Planet Factory

Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA).

First Exposed Planetary Core Discovered

A year that is a mere 18 hours TOI 849 b is an extremely unusual planet in the so-called "Neptune Desert" - a term used by astronomers for a region close to stars where we rarely see planets of Neptune's mass or larger.

Super Earths Discovered Orbiting Nearby Red Dwarf Gliese 887

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

Rogue's Gallery Of Dusty Star Systems Reveals Exoplanet Nurseries

Astronomers this month released the largest collection of sharp, detailed images of debris disks around young stars, showcasing the great variety of shapes and sizes of stellar systems during their prime planet-forming years. Surprisingly, nearly all showed evidence of planets.
