Astronomers Discover "Inside-Out" Planetary System With Rocky World Beyond Gas Planets, Challenging Formation Theories
Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

Unique Inside-Out Planetary System Reveals Unexpected Rocky World on the Outer Edge
Astronomers have discovered a rare inside-out planetary system around LHS 1903, where a rocky planet exists beyond gas giants. Using ESA’s CHEOPS telescope, researchers found evidence that planets formed one after another in a gas-depleted environment, challenging long-standing theories about how planetary systems form and evolve across the galax...

High-Resolution Observations Provide New Insights into Brown Dwarf HD 206893 B
Astronomers have gained significant insights into brown dwarf HD 206893 B using high-resolution spectroscopy. The study, led by UCSD's Ben Sappey, reveals the object's mass, temperature, and formation details, contributing to brown dwarf research. Located 133 light-years away, HD 206893 B's position within a debris disk invites future investigation...

Trillions of Comets Found in 74 Alien Star Systems, Unveiling Exocomets and Planetary Belts
A discovery of trillions of comets in 74 star systems has opened new doors for understanding the role of exocomets in planetary water sources. The planetesimal belts, detected using ALMA and SMA telescopes, offer crucial insights into the evolution of planetary systems and the potential for life-supporting water on distant planets. This research pa...

Study Of "Twin" Stars Finds Evidence Of Planetary Ingestion
The planetary system that includes Earth and its sibling planets orbiting the sun has been remarkably stable during its roughly 4.5 billion years of existence.

Dead Star Caught Ripping Apart Planetary System in a Rare Incidence of Cosmic Cannibilism
The discovery was made by analysing archival data from NASA's Hubble Telescope and other observatories of the American space agency. Termed cosmic cannibalism, the observation helped shed light on the violent nature of the evolved planetary system and can help astronomers in understanding the makeup of newly forming systems.

New Planet-Eating 'Death Star' Could Tell History Of Planetary Systems
An international team of scientists has discovered a planetary system with a host star similar to Earth's sun, which could tell the history and connections between stars and their planets. Among the findings of the star, is the intriguing bit that the star's unusual composition indicates it ingested some of its planets.

Astronomers Find Star With 3 Super-Earths
Astronomers said on Thursday they had found a planetary system with three super-Earths orbiting a bright, dwarf star -- one of them likely a volcanic world of molten rock.

Milky Way May be Home to Billions of Planets in 'Habitable' Zones, Says Study
The Milky Way galaxy may be home to billions of planets orbiting their host stars in a "habitable zone" where life could theoretically exist, researchers said today.
