Astronomers spot potentially habitable planet and star closely resembling Earth and Sun

Astronomers have discovered a potentially habitable exoplanet and its star-- both with striking similarities to the Earth and our Sun. The exoplanet candidate called KOI-456.04, which is about 1.9 times the size of ours, is at the right distance from its star, which...

K2 18b

Two Super-Earths around red dwarf K2-18

New research using data collected by the European Southern Observatory (ESO) has revealed that a little-known exoplanet called K2-18b could well be a scaled-up version of Earth. Just as exciting, the same researchers also discovered for the first time that the...

Planet 9 - the first exoplanet within our home solar system

The newest computer simulation, conducted by researchers from the Lund University in Sweden, suggests the so-called Planet 9 is most likely an exoplanet. If the discovery proves correct, it will make it the first exoplanet revealed inside our home solar system and,...

Astronomers create the first weather map of a giant Jupiter-like exoplanet

For the first time, astronomers have actually mapped the weather of an exoplanet beyond our Solar System. Astronomers have found that gas giant HD 189733b has winds swirling at 8690 km/h (5400 mph). This is due to the planets extremely close orbit around its host...

Gemini discovers a young, Jupiter-like planet

Astronomers have imaged a new world of a young Jupiter in unprecedented details, using the Gemini Observatory's new Planet Imager (GPI). They discovered the planet's mass is about twice the Jupiter's, and it seems the planet is the most Solar System-like pla

Smallest exoplanet found to have water vapour

The smallest exoplanet (about the size of Neptune) HAT-P-11b have been discovered to have clear skies and steamy water vapors as observed by astronomers using data from three of NASA's space telescopes - Hubble, Spitzer and Kepler.John Grunsfeld, assistant administr

UEA research shows oceans vital for possibility of alien life

Researchers at the University of East Anglia have made an important step in the race to discover whether other planets could develop and sustain life. Their new research, published yesterday in the journal Astrobiology, shows the vital role of oceans in m

Astronomers find a new type of planet: the "mega-Earth"

Astronomers announced today that they have discovered a new type of planet - a rocky world weighing 17 times as much as Earth. Theorists believed such a world couldn't form because anything so hefty would grab hydrogen gas as it grew and become a Jupiter-like gas gi

Diamond planets more common than thought

Carbon-rich planets may be more common than previously thought, according to a new research by Yale University astronomers.Some of these planets, all located far beyond Earth's solar system, could contain vast deposits of graphite or diamonds, and their apparent abu

First Earth-size planet found In the 'habitable zone' of another star

Astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" - the range of distance from a star where liquid water might pool on the surface of an orbiting planet and could possibly sustain life. The planet, called

Signs of water found in the atmospheres of 5 distant exoplanets

The presence of atmospheric water was reported previously on a few planets orbiting stars beyond our solar system, but a paper published yesterday in Astrophysical Journal is the first one that conclusively measured and compared the profiles and

First map of clouds on an exoplanet

On the exoplanet Kepler 7b, the weather is highly predictable, an international team of scientists has found: On any given day, the exoplanet, which orbits a star nearly 1,000 light-years from Earth, is heavily overcast on one side, while the other side likely enjoys

Where it rains glass - Hubble finds a bizarre blue exoplanet

Astronomers at NASA's Hubble Space Telescope have, for the first time, identified a true color of planed out of our Solar System. The planet is 63 light-years away and is boringly named HD 189733b but it is rather interesting, bizarre and exotic. It is also

New method of finding planets scores its first discovery

A team at Tel Aviv University and the Harvard-Smithsonian Center for Astrophysics (CfA) has just discovered an exoplanet using a new method that relies on Einstein's special theory of relativity. Detecting alien worlds presents a significant challenge since they

New technology aims at improvising exoplanet discovery

A new advanced telescope imaging system is expected to improve detection of exoplanets obscured by exponentially bright stars. Unlike Kepler mission which uses the transit method to find out exoplanets transiting in front of their stars, this one actually blots out

Measuring a distant planet's transit (The Exoplant Transit Method)

Astronomers first discovered evidence of a new planet outside of our solar system in 1995. Since then astronomers have discovered 529 other planets. These planets outside our solar system, referred to as extra-solar planets or in short exoplanets, have been detected
