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.

Astronomers at the Center for Astrophysics | Harvard & Smithsonian have detected the first Jupiter-like planet without clouds or haze in its observable atmosphere. The findings were published this month in the Astrophysical Journal Letters.

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.

Shortly after NASA's Kepler mission began operations back in 2009, the space telescope spotted what was thought to be a planet about half the size of Saturn in a multiple-star system.

By monitoring the cosmos with a radio telescope array, a Cornell University-led international team of scientists has detected radio bursts emanating from the constellation Boötes. The signal could be the first radio emission collected from a planet beyond our solar system.

This is the first time that astronomers have been able to measure the motion of a massive Jupiter-like planet that is orbiting very far away from its host stars and visible debris disk.

Among the most extreme planets discovered beyond the edges of our solar system are lava planets: fiery hot worlds that circle so close to their host star that some regions are likely oceans of molten lava.

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.

Astronomers have found compelling evidence that planets start to form while infant stars are still growing.

A team led by an astronomer from the University of Kansas has crunched data from NASA's TESS and Spitzer space telescopes to portray for the first time the atmosphere of a highly unusual kind of exoplanet dubbed a "hot Neptune."

Astronomers using the GRAVITY instrument at the VLT telescopes in Chile have now obtained the first direct confirmation of an exoplanet discovered by radial velocity.

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.

An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found a peculiar dust ring system around the young triple star GW Orionis.

We've never met some of the Sun's closest neighbors until now. In a new study, astronomers report the discovery of 95 objects known as brown dwarfs, many within a few dozen light-years of the Sun.

An international team of astronomers including Gisela Ortiz-Leon from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn discovered a Saturn-like planet orbiting a small, cool star by detecting the "wobble" in the star's motion caused by the gravitational pull of the planet.

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).

The European Southern Observatory's Very Large Telescope (ESO's VLT) has taken the first ever image of a young, Sun-like star accompanied by two giant exoplanets.

Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.

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.

Understanding how planets form is one of the main challenges scientists face when placing our own and other planetary systems in context.
