A glimpse from outer space.

Mysterious Planet 9 that's hiding somewhere in our solar system might be stolen from another star

One group from Lund University in Sweden says Planet 9 or Planet X, as it's sometimes called, might actually be an exoplanet, initially formed in another solar system but captured by our sun in an interstellar gravity tug of war.

What makes a planet? Finally a simple formula that includes exoplanets as well

There is only one clear set of official criteria by which we class or not a cosmic body as a planet. These criteria introduced in 2006 by the International Astronomical Union saw Pluto demoted to the status of dwarf planet. Oddly enough, though, these rules were made for classing planets only in our solar system, meaning the 5,000 exoplanets (what should be planets outside our solar system) identified so far are now in a "definitional limbo," according to planetary astronomer Jean-Luc Margot at UCLA. Luckily, Margot has come up with a solution which seems to work marvelously.

Automated process finds three super-Earths in our neighborhood - a new way to hunt for alien planets

Using three state of the art ground-based telescopes, a team of astronomers has identified three super-Earth exoplanets that are seven to eight times as massive as our own planet and orbit their parent star closer than Mercury orbits the sun. What's hot about the findings - apart from the planet's likely scorching surface - is that these were made using a novel automated approach, in which one telescope called the Automated Planet Finder (APF) Telescope at Lick Observatory in California was programmed to scour the night's sky and look for signs of nearby alien planets. These three planets are just the beginning of a new process that hopefully will return hundreds of planets in our neighborhood, all without the need for human supervision.

NASA officially starts program to look for alien life

Just after NASA researchers made the bold claim that they will find alien life in less than 20 years, the space agency has officially launched a project to look for it. The Nexus for Exoplanet System Science, or “NExSS” will be a project integrating several fields of science, aiming to better understand exoplanets with the potential to host life, as well as planet-life interactions.

Most stars might hold habitable planets, researchers calculate

According to Danish and Australian researchers, there are billions of the stars in the Milky Way located in the "habitable zone", where liquid water might exist, and with it, life as we know it.

Five ancient alien planets discovered in 11 billion-year-old solar system

The ever resourceful Kepler missions just reported its most interesting find to date: not one, but five planets smaller than Earth orbiting a star 117 light-years away that’s estimated to be 11 billion years old. This makes it far older than our own sun, meaning its planets could be 2.5 times as old as Earth. […]

Not one, but two yet to be confirmed Earth-sized planets could orbit in the outer solar system

Nibiru followers might have cause to rejoice, as Spanish astronomers report a novel hypothesis that suggests two Earth-sized planets might be hiding out in the outskirts of our solar system. Thousands of years after the first planets besides our own were discovered by ancient Babylonian astronomers, it seems like determining the number of planets in our solar is far from being settled, despite Pluto's unfortunate destitution.

Kepler crossed the 1,000 discovered alien planets milestone

Since it was first launched in 2009, the $600 Kepler mission has discovered more than 1,000 alien worlds. Arguably it's one of the most successful space mission in history so far, further cementing its status as a legend. The milestone was breached after eight newly confirmed exoplanets were added to the tally, two of which are very similar to Earth and thus could support alien life.

Earth-like planet spotted for the first time with a ground-based telescope

Space-based telescopes have been used to spot planets (even Earth-like planets) for years now, but this is the first time ever that a ground-based telescope has detected an Earth like planet. A telescope based on the ground in La Palma (one of the Canary Islands) called Nordic has found 55 Cancri e, an exoplanet two times bigger than […]

A 'Ying Yang' binary system that can sustain Planetary Formation

A group from the Laboratory of Astrophysics of Bordeaux, France, and the National Centre for Scientific Research (CNRS) has made a most exciting discovery. The astronomers found that an odd binary system – a solar system comprised of two stars – actually behaves like a double star, with two disks of matter encircling the system in a […]

Neptune-sized alien planet found to harbor water vapor in its atmosphere

Astronomers have discovered water vapor in the atmosphere of a new exoplanet - a planet from outside our solar system - roughly the size of Neptune, orbiting a star 124 light-years away. This is the first time water vapor has been found on an alien planet smaller than Jupiter. The discovery is set to improve scientists' understanding of how planet forms and which planets may be best suited to support alien life.

NASA reports the first Earth-sized Exoplanet in the Habitable Zone

Remember a few days ago, when I was telling you about the big conference NASA had planned for today? Well, they sure didn’t disappoint! The team of astrophysicists from the SETI Institute and NASA’s Ames Research Center have just reported a major milestone: for the first time, they have found an Earth-sized planet at the right distance […]

First possible evidence of an exomoon

Until just a few decades ago, there wasn’t any proof that there were any planets beyond those in our solar system, although of course everybody expected them to exist somewhere. After the Kepler Space Telescope was deployed, astronomers found not one, but a couple hundred exoplanets (planets orbiting other stars). In fact, our galaxy is […]

First images from Gemini capture planets outside our solar system

In the past few decades planet hunters have confirmed a couple hundred alien planets, with hundreds more on the waiting list. Think about it, hundreds or thousands of light years away a myriad of alien planets exist, maybe some similar to our very own Earth, which scientists are ferociously studying. There many technical limitations however. […]

Newly found gassy exoplanet has mass similar to Earth's

A team of astronomers recently discovered a new exoplanet some 200 light years away whose mass is about the same as Earth’s – the first Earth-mass planet that transits, or crosses in front of, its host star. Although very similar in mass, the planet is 60% larger in diameter suggesting it has a thick atmosphere. […]

New, more precise method to measure exoplanet mass

In the past two decades alone, some 900 exoplanets – planets outside our solar system – have been identified, with some 2300 more in queue. Most of these were confirmed using the now discontinued Kepler space telescope. It’s remarkable how much scientists can find out about a distant plant, hundreds of light years away, simply […]

Signs of water found in the atmosphere of 5 alien planets

Using the Hubble telescope, astronomers have identified faint signals of water in the atmosphere of five exoplanets. The alien planets, however, are classed as hot-Jupiters – huge planets with a surface temperature too hot to support life. Finding water on planets light years away from Earth is definitely of great note and marks a step […]

Most Earth-like exoplanet in terms of size and mass discovered

Although the Kepler Space Telescope itself is defunct due to a malfunction that rendered it out of operation some months ago, the mission goes on as scientists churn through massive amounts of data gathered by Kepler, enough to keep them busy for years to come. One of the fruits of Kepler is an exoplanet called  Kepler […]

Kepler telescope malfunction might end search for alien planets

Dire news came today. Astronomers, and people dreaming of life beyond our solar system alike all over the world, are morning the loss of the Kepler – the space telescope tasked with discovering exoplanets capable of supporting life. One of the telescope’s wheels failed and as such, the telescope can’t stabilize its gaze on a […]

Alien planet spotted using Einstein's theory of relativity

A new alien planet has been found by astronomers who have a novel planet hunting method which makes good use of Einstein’s special theory of relativity. The newly found exoplanet is slightly larger than Jupiter and is the first such planet found with this method. The planet orbits a star in the constellation Cygnus, about […]

Most promising Earth-like planets found by Kepler

The ever resourceful Kepler mission has recently unveiled several new possible Earth-like planet candidates, two of whom are favored by scientists with the best odds yet of supporting alien life. The pair actually orbits around the same star, called Kepler 62, after NASA’s Kepler spacecraft, which is smaller and dimmer than our own star. Kepler 62 […]

First remote reconnaissance of another solar systems reveals unlike "any other known object in our Universe"

Researchers have for the first time conducted a remote reconnaissance of a distant planetary system with a new telescope imaging system. Peeking at other planets Project 1640 is a dedicated high contrast imaging program at Palomar Observatory with the goal of obtaining images and spectra of brown dwarfs and planetary mass companions to nearby stars. […]

Alien life hunters hold white dwarf stars as safest bet

Though hundreds of potentially life harboring exoplanets have been discovered thus far, until the James Webb Space Telescope becomes operational, sometime around 2018, scientists today lack the resources to peer into the guts of these planet and  determine a realistic chance of hosting life. Even when the JWT goes live, however, it will take hundreds […]

Earth-like planets closer than previously thought. Nearest one might lie 13 light-years away

After researchers surveyed data from the Kepler mission tasked with identifying possibly habitable planets outside our solar system they found that 6% of red dwarfs – the most common type of planets – are within this zone. This new adjustment would mean that the nearest Earth-like planet might lie just 13 light years away. Astronomers […]

Technique that allows mapping of distant worlds might allow us to find the next Earth

The Kepler mission has proven to be invaluable to science today thanks to its formidable discoveries of exoplanets in our galaxy. It’s rather remarkable how scientists can tell so much from so little, like the size, mass, orbit and sometimes even composition of a distant planet all by analyzing light. On other hand, it’s frustrating […]

Super-earth planets might have a magnetic field from liquid metals

Of the hundreds of exoplanets discovered thus far, many of them are classed as super-Earths, planets with a mass up to ten times that of our planet. Due to their inherent different structure however, their cores would be far from being similar to that of the Earth, leading many scientist to claim that they might […]

New super-Earth exoplanet is a mere 46 light-years away

Astronomers have used a novel planet hunter instrument to detect a new possible life supporting, Earth-like exoplanet. In fact the new planet is classed as a super-Earth, since it has a minimum mass of 7.1 times that of our planet, and is properly located on its parent star’s orbit to support the presence of liquid […]

European Observatory (ESO) assembles 9 gigapixel image with 84 million stars

The European Southern Observatory has captured and analyzed an image of the center of our galaxy which, if printed at normal resolution, would measure 9 x 7 meters. The enormous 9 gigapixel image features the very center of the Milky Way and was created not to be a background for huge screens, but to help […]

New ESA planet-hunter space telescope slated for 2017

The European Space Agency has officially announced that it will launch a new space telescope tasked with the primary objective of finding Earth-like planets in our neighboring cosmic backyard. Though the mission’s budget is rather small, there’s nothing modest about its goals. Dubbed CHEOPS or CHaracterising ExOPlanets Satellite, at the end of its 3.5 year-long scheduled mission the […]

Newly discovered solar system is very similar to our own

Researchers at MIT, the University of California at Santa Cruz and other institutions have come across the first exoplanetary system, whose planets exhibit a regularly aligned orbit, after analyzing data from NASA’s Kepler space telescope. So far, other discovered exoplanetary systems had planets, particularly hot-Jupiters, which presented  far more eccentric orbits. Our solar system is comprised of eight […]

Venus at its brightest this week, while Venus transit marks once in a life time opportunity next month

Summer is set to kick-off with a series of beautiful Venus related events, from an astronomical point of view at least. This week, the planet will appear at its brightest in the night sky, as it nears almost ideal observational circumstances – close distance to Earth and sun phase. Also, at the beginning of June, […]

Turns out, another solar system has more planets than ours

Our solar system is special for two reasons: the first one, obviously – is us. Our solar system is the only one we know of so far that hosts life. The second one is the number of planets – no other solar system that we’ve seen until now had as many planets as ours, but […]

How many Earth-like planets are there in the Milky Way? Billions, according to astronomers

One of the most outstanding dreams astronomers and other scientists hope to accomplish is to someday encounter proof that extraterestrial life exists. Intelligent life might be extremely far off, however microbiological life should without a doubt be present elsewhere other than our planet or solar system. For life to blossom, however, the right conditions have […]

"Water-world" alien planet confirmed by Hubble

The hunt for the second Earth, a similar life-bearing paradise like our own, rages on, and while no candidate came any close so far, scientists have made some extraordinary discoveries in the process. The latest exciting find is a super-Earth, a planet larger than Earth, but no bigger than Neptune, that represents the first of […]

Newly discovered "super-Earth" planet might support life

The hunt for finding another Earth is making progress every day, as scientists are constantly adding new viable candidates to the list. It’s estimated that in our galaxy alone, the Milky Way, there are between 200 and 400 billion stars – out of all of these, from a statistical point of view, the chances of […]

Kepler's hunt for Earth-like planets

In our very own Milky Way galaxy alone,  astronomers estimate there are between 200 billion and 400 billion stars. Of these, there are many that exoplanets within their solar systems. Still, what are the odds planets, more or less similar to our one, capable of supporting life, microscopic or otherwise, exist? This is the exact […]

Two new exoplanets spotted by astro gamers

This news couldn’t have come any sooner.
