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.

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.

Jupiter-size planets orbiting close to their stars have upended ideas about how giant planets form. Finding young members of this planet class could help answer key questions.

Giant planets in our solar system and circling other stars have exotic clouds unlike anything on Earth, and the gas giants orbiting close to their stars -- so-called hot Jupiters -- boast the most extreme.

New evidence shows the first-ever pictures capturing the birth of a pair of planets orbiting the star PDS 70 are in fact authentic.

An international team of researchers, led by astronomers from the University of Amsterdam (the Netherlands), has directly demonstrated the presence of iron in the atmosphere of an exoplanet for the first time.

An international team of astronomers has captured fifteen images of the inner rims of planet-forming disks located hundreds of light years away.

WASP-79b Has Yellow Skies And Iron Rain

The weather forecast for the giant, super-hot Jupiter-size planet WASP-79b is steamy humidity, scattered clouds, iron rain, and yellow skies.

Our solar system has a king. The planet Jupiter, named for the most powerful god in the Greek pantheon, has bossed around the other planets through its gravitational influence.
