The red dwarf star, called AU Microscopii, or AU Mic, is located outside of our solar system, 32 light-years from Earth, which is relatively close. It’s home to one of the youngest planetary systems ever observed, and the star is less than 100 million years old, as per CNN.

Research shows there are four classes of planetary systems
Updated : 3 years ago IST
Therefore, the researcher developed a framework to determine the differences and similarities between planets of the same systems. And in doing so, he discovered that there are not two, but four such system architectures.

Planetary system's second Earth-size world discovered
Updated : 3 years, 2 months ago IST
Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star, the range of distances where liquid water could occur on a planet's surface. The world is 95% Earth's size and likel

Astronomers find that two exoplanets may be mostly water
Updated : 3 years, 2 months ago IST
A team led by UdeM astronomers has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," planets where water makes up a large fraction of the volume. These worlds, located in a planetary system 218 light-years away in the constellation Lyra, are unlike any planets

Early planetary migration can explain missing planets: Study
Updated : 3 years, 4 months ago IST
A new model that accounts for the interplay of forces acting on newborn planets can explain two puzzling observations that have cropped up repeatedly among the more than 3,800 planetary systems cataloged to date.

New study finds oldest planetary debris in our galaxy
Updated : 3 years, 4 months ago IST
Astronomers led by the University of Warwick have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way.

Check out what is the heaviest element ever found in exoplanet's atmospher
Updated : 3 years, 5 months ago IST
Lisbon [Portugal], October 13 (ANI): The heaviest element ever identified in an exoplanet atmosphere, barium, has been found by astronomers using the Very Large Telescope (VLT) of the European Southern Observatory. They were shocked to find barium in the atmospheres of the exoplanets WASP-76

Study finds rocking shadow effect in protoplanetary discs`
Updated : 3 years, 7 months ago IST
Washington [US], July 18 (ANI): The "rocking shadow" effect, described by astronomers from the University of Warwick, shows how discs in emerging planetary systems are oriented and how they travel around their host star. The outcome also provides hints as to how they might change over time.

London [England], February 12 (ANI): White dwarfs are glowing embers of stars that have burned through all their hydrogen fuel. Nearly all stars, including the Sun, will eventually become white dwarfs, but very little is known about their planetary systems. A new study revealed the discovery

Astronomers observe final moments of planetary remnants for the first time
Updated : 4 years, 1 month ago IST
Coventry [England], February 10 (ANI): A white dwarf is known to be a small very dense star that is typically the size of a planet. It is formed when a low-mass star has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula. Astronomers at the University of W

Artificial Intelligence predicts which planetary systems will survive
Updated : 5 years, 8 months ago IST
Washington D.C. [USA], July 14 (ANI): Rejecting the large range of unstable possibilities -- all the configurations that would lead to collisions -- would leave behind a sharper view of planetary systems around other stars, but it's not as easy as it sounds.

Newly discovered planet zips around baby star in a week
Updated : 5 years, 8 months ago IST
Washington D.C. [USA], June 24 (ANI): Understanding how planets form is one of the main challenges scientists face when placing our own and other planetary systems in context. Planets are thought to form from the disk-shaped clouds of gas and dust that surround newborn stars, but this pro
