Is your favorite Star Wars planet a desert world or an ice planet or a jungle moon?
Itâs possible that your favorite planet exists right here in our galaxy. Astronomers have found over 3,400 planets around other stars, called âexoplanets.â
Some of these alien worlds could be very similar to arid Tatooine, watery Scarif and even frozen Hoth, according to NASA scientists.
Find out if your planet exists in a galaxy far, far away or all around you.
Were you going to the Tosche station to pick up some power converters? Hold on a minute and learn about Kepler-16b, 200 light-years from Earth. Itâs the first honest-to-goodness planet ever found where you could watch two suns set like Luke. George Lucas himself even blessed its nickname âTatooine.â Itâs not a perfect comparison: Kepler-16b is a cold gas giant roughly the size of Saturn. But donât worry, kid.
The best part is that Tatooine aka Kepler-16b was just the first. It has family. A LOT of family. Half the stars in our galaxy are pairs, rather than single stars like our sun. If every star has at least one planet, thatâs billions of worlds with two suns. Billions! Maybe waiting for life to be found on them.
If youâre like Finn and want to know why everyone wants to go back to Jakku desert planets, get this: Star Wars may be reflecting the real universe. Desert worlds are not only a very real possibility, but we think they are probably very common. They can be hot, like the fictional Tatooine and Jakku, or cold, like Jedha in âRogue Oneâ or our real planet Mars.
Perhaps itâs not so weird that both Luke and Rey grew up on planets that look suspiciously like each other. If youâre scouring the universe for a place to settle, you have a good chance of finding a desert planet.
There is a Hoth in our galaxy! Though not the same Hoth from âThe Empire Strikes Backâ (no invading Imperials, for one). The icy super-Earth reminded scientists so much of the frozen Rebel base they nicknamed it âHoth.â The planetâs real name is OGLE 2005-BLG-390L.
Our galaxyâs Hoth is too cold to support life as we know it. But life may evolve under the ice of a different world, or a moon in our solar system.
Weâre currently designing a mission to look for life under the crust of Jupiterâs icy moon Europa. Weâre pretty sure ity wonât look like tauntauns, if it exists.
Both the forest moon of Endor and Takodana, the home of Han Soloâs favorite cantina in âForce Awakens,â are green like our home planet. But astrobiologists think that plant life on other worlds could be red, black, or even rainbow-colored!
In August 2016, astronomers from the European Southern Observatory announced the discovery of Proxima Centauri b, a planet only four light-years away from Earth, which orbits a tiny red star.
The light from a red star, also known as an M dwarf, is dim and mostly in the infrared spectrum (as opposed to the visible spectrum we see with our sun). And that could mean plants with wildly different colors than what weâre used to seeing on Earth. Or, animals that see in the near-infrared.
The next few years will see the launch of a new generation of spacecraft to search for planets around other stars. TESS and the James Webb Telescope will go into space in 2018, and WFIRST in the mid-2020s. Thatâs one step closer to finding life.

Han Solo in a nutshell
i donât understand why people arenât interested in astronomy
like you can look up into the night sky and see a fucking galaxy with your naked eye like you can see cosmic structures that are millions of light years across and if you donât think thatâs the coolest fucking shit then iono what to tell you
Voyager, with its outer solar system tour and interstellar observations, is often credited as the greatest robotic space mission. But today we remember the plucky Pioneers, the spacecraft that proved Voyagerâs epic mission was possible.
Forty-five years ago this week, scientists still werenât sure how hard it would be to navigate the main asteroid belt, a massive field of rocky debris between Mars and Jupiter. Pioneer 10 helped them work that out, emerging from first the first six-month crossing in February 1973. Pioneer 10 logged a few meteoroid hits (fewer than expected) and taught engineers new tricks for navigating farther and farther beyond Earth.
Pioneer 11 was a backup spacecraft launched in 1973 after Pioneer 10 cleared the asteroid belt. The new mission provided a second close look at Jupiter, the first close-up views of Saturn and also gave Voyager engineers plotting an epic multi-planet tour of the outer planets a chance to practice the art of interplanetary navigation.
Three-hundred and sixty-three years after humankind first looked at Jupiter through a telescope, Pioneer 10 became the first human-made visitor to the Jovian system in December 1973. The spacecraft spacecraft snapped about 300 photos during a flyby that brought it within 81,000 miles (about 130,000 kilometers) of the giant planetâs cloud tops.
Pioneer began as a Moon program in the 1950s and evolved into increasingly more complicated spacecraft, including a Pioneer Venus mission that delivered a series of probes to explore deep into the mysterious toxic clouds of Venus. A family portrait (above) showing (from left to right) Pioneers 6-9, 10 and 11 and the Pioneer Venus Orbiter and Multiprobe series. Image date: March 11, 1982.Â
Classic rock has Van Halen, we have Van Allen. With credits from Explorer 1 to Pioneer 11, James Van Allen was a rock star in the emerging world of planetary exploration. Van Allen (1914-2006) is credited with the first scientific discovery in outer space and was a fixture in the Pioneer program. Van Allen was a key part of the team from the early attempts to explore the Moon (heâs pictured here with Pioneer 4) to the more evolved science platforms aboard Pioneers 10 and 11.
For more than 25 years, Pioneer 10 was the most distant human-made object, breaking records by crossing the asteroid belt, the orbit of Jupiter and eventually even the orbit of Pluto. Voyager 1, moving even faster, claimed the most distant title in February 1998 and still holds that crown.
We last heard from Pioneer 10 on Jan. 23, 2003. Engineers felt its power source was depleted and no further contact should be expected. We tried again in 2006, but had no luck. The last transmission from Pioneer 11 was received in September 1995. Both missions were planned to last about two years.
Pioneers 10 and 11 are two of five spacecraft with sufficient velocity to escape our solar system and travel into interstellar space. The other threeâVoyagers 1 and 2 and New Horizonsâare still actively talking to Earth. The twin Pioneers are now silent. Pioneer 10 is heading generally for the red star Aldebaran, which forms the eye of Taurus (The Bull). It will take Pioneer over 2 million years to reach it. Pioneer 11 is headed toward the constellation of Aquila (The Eagle) and will pass nearby in about 4 million years.
Years before Voyagerâs famed Golden Record, Pioneers 10 and 11 carried the original message from Earth to the cosmos. Like Voyagerâs record, the Pioneer plaque was the brainchild of Carl Sagan who wanted any alien civilization who might encounter the craft to know who made it and how to contact them. The plaques give our location in the galaxy and depicts a man and woman drawn in relation to the spacecraft.

Our Cassini spacecraft has been exploring Saturn, its stunning rings and its strange and beautiful moons for more than a decade.
Having expended almost every bit of the rocket propellant it carried to Saturn, operators are deliberately plunging Cassini into the planet to ensure Saturnâs moons will remain pristine for future exploration â in particular, the ice-covered, ocean-bearing moon Enceladus, but also Titan, with its intriguing pre-biotic chemistry.
Under its shroud of haze, Saturnâs planet-sized moon Titan hides dunes, mountains of water ice and rivers and seas of liquid methane. Of the hundreds of moons in our solar system, Titan is the only one with a dense atmosphere and large liquid reservoirs on its surface, making it in some ways more like a terrestrial planet.
Both Earth and Titan have nitrogen-dominated atmospheres â over 95% nitrogen in Titanâs case. However, unlike Earth, Titan has very little oxygen; the rest of the atmosphere is mostly methane and traced amounts of other gases, including ethane.
There are three large seas, all located close to the moonâs north pole, surrounded by numerous smaller lakes in the northern hemisphere. Just one large lake has been found in the southern hemisphere.
The moon Enceladus conceals a global ocean of salty liquid water beneath its icy surface. Some of that water even shoots out into space, creating an immense plume!
For decades, scientists didnât know why Enceladus was the brightest world in the solar system, or how it related to Saturnâs E ring. Cassini found that both the fresh coating on its surface, and icy material in the E ring originate from vents connected to a global subsurface saltwater ocean that might host hydrothermal vents.
With its global ocean, unique chemistry and internal heat, Enceladus has become a promising lead in our search for worlds where life could exist.
Saturnâs two-toned moon Iapetus gets its odd coloring from reddish dust in its orbital path that is swept up and lands on the leading face of the moon.
The most unique, and perhaps most remarkable feature discovered on Iapetus in Cassini images is a topographic ridge that coincides almost exactly with the geographic equator. The physical origin of the ridge has yet to be explainedâŠ
It is not yet year whether the ridge is a mountain belt that has folded upward, or an extensional crack in the surface through which material from inside Iapetus erupted onto the surface and accumulated locally.
Saturnâs rings are made of countless particles of ice and dust, which Saturnâs moons push and tug, creating gaps and waves.
Scientists have never before studied the size, temperature, composition and distribution of Saturnâs rings from Saturn obit. Cassini has captured extraordinary ring-moon interactions, observed the lowest ring-temperature ever recorded at Saturn, discovered that the moon Enceladus is the source for Saturnâs E ring, and viewed the rings at equinox when sunlight strikes the rings edge-on, revealing never-before-seen ring features and details.
Cassini also studied features in Saturnâs rings called âspokes,â which can be longer than the diameter of Earth. Scientists think theyâre made of thin icy particles that are lifted by an electrostatic charge and only last a few hours. Â
The powerful magnetic field that permeates Saturn is strange because it lines up with the planetâs poles. But just like Earthâs field, it all creates shimmering auroras.
Auroras on Saturn occur in a process similar to Earthâs northern and southern lights. Particles from the solar wind are channeled by Saturnâs magnetic field toward the planetâs poles, where they interact with electrically charged gas (plasma) in the upper atmosphere and emit light. Â
Saturnâs turbulent atmosphere churns with immense storms and a striking, six-sided jet stream near its north pole.
Saturnâs north and south poles are also each beautifully (and violently) decorated by a colossal swirling storm. Cassini got an up-close look at the north polar storm and scientists found that the stormâs eye was about 50 times wider than an Earth hurricaneâs eye.
Unlike the Earth hurricanes that are driven by warm ocean waters, Saturnâs polar vortexes arenât actually hurricanes. Theyâre hurricane-like though, and even contain lightning. Cassiniâs instruments have âheardâ lightning ever since entering Saturn orbit in 2004, in the form of radio waves. But it wasnât until 2009 that Cassiniâs cameras captured images of Saturnian lighting for the first time.
Cassini scientists assembled a short video of it, the first video of lightning discharging on a planet other than Earth.
Cassiniâs adventure will end soon because itâs almost out of fuel. So to avoid possibly ever contaminating moons like Enceladus or Titan, on Sept. 15 it will intentionally dive into Saturnâs atmosphere.
The spacecraft is expected to lose radio contact with Earth within about one to two minutes after beginning its decent into Saturnâs upper atmosphere. But on the way down, before contact is lost, eight of Cassiniâs 12 science instruments will be operating! More details on the spacecraftâs final decent can be found HERE.
