The Planet Does Not Fall Far From The Star

A compositional link between planets and their respective host star has long been assumed in astronomy.

Exoplanet hunters have found thousands of planets, most orbiting close to their host stars, but relatively few alien worlds have been detected that float freely through the galaxy as so-called rogue planets, not bound to any star.

Considered an ultra-hot Jupiter - a place where iron gets vaporized, condenses on the night side and then falls from the sky like rain - the fiery, inferno-like WASP-76b exoplanet may be even more sizzling than scientists had realized.

Cloud Spotting On A Distant Exoplanet

An international team of astronomers has not only detected clouds on the distant exoplanet WASP-127b, but also measured their altitude with unprecedented precision.

The familiar star at the center of our solar system has had billions of years to mature and ultimately provide life-giving energy to us here on Earth. But a very long time ago, our sun was just a growing baby star.

Researchers led by Osaka University and NASA find that the distribution of cold planets in the Milky Way is not strongly dependent on the distance from the Galactic center

Astronomers have developed the most realistic model to date of planet formation in binary star systems.

Using the Atacama Large Millimetre/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have unambiguously detected the presence of a disc around a planet outside our Solar System for the first time.

Are We Missing Other Earths?

Some exoplanet searches could be missing nearly half of the Earth-sized planets around other stars.

While studying two exoplanets in a bright nearby star system, the CHEOPS satellite has unexpectedly spotted the system's third known planet crossing the face of the star.

Four planets locked in a perfect rhythm around a nearby star are destined to be pinballed around their solar system when their sun eventually dies, according to a study led by the University of Warwick that peers into its future.

Watching A Large Planet Form

NASA's Hubble Space Telescope is giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star.

In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them.

NASA's Nancy Grace Roman Space Telescope will create enormous cosmic panoramas, helping us answer questions about the evolution of our universe.

Astronomers have found evidence that the first exoplanet that was identified transiting its star could have migrated to a close orbit with its star from its original birthplace further away.

A newly discovered planet could be our best chance yet of studying rocky planet atmospheres outside the solar system, a new international study involving UNSW Sydney shows.

Mini-Neptunes and super-Earths up to four times the size of our own are the most common exoplanets orbiting stars beyond our solar system.

High Schoolers Discover Four Exoplanets

The high schoolers turned scientists published their findings this week, thanks to a research mentorship program at the Center for Astrophysics; Harvard and Smithsonian

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.
