We Just Identified More Than 200 New (Potential) Planets
The Kepler space telescope is our first mission capable of identifying Earth-size planets around other stars. On Monday, June 19, 2017, scientists from many countries gathered at our Ames Research Center to talk about the latest results from the spacecraft, which include the identification of more than 200 potential new worlds! Here’s what you need to know:
We found 219 new planet candidates.
All of these worlds were found in a patch of sky near the Cygnus constellation in our Milky Way galaxy. Between 2009 and 2013, Kepler searched more than 200,000 stars in the region for orbiting planets. The 219 new planet candidates are part of the more than 4,000 planet candidates and 2,300 confirmed planets Kepler has identified to date.
Ten of these worlds are like our own.
Out of the 219 new planet candidates, 10 are similar to Earth. The planets are about the right size to be a terrestrial world, and orbit their star in the habitable zone–the range of distances from a star where liquid water could pool on the surface of a rocky planet.
Small planets come in two sizes.
Kepler has opened up our eyes to the existence of many small worlds. It turns out a lot of these planets are either approximately 1.5 times the size of Earth or just smaller than Neptune. The cool names given to planets of these sizes? Super Earths and mini-Neptunes.
Some of the new planets could be habitable.
Water is a key ingredient to life as we know it. Many of the new planet candidates are likely to have small rocky cores enveloped by a thick atmosphere of hydrogen and helium, and some are thought to be ocean worlds. That doesn’t necessarily mean the oceans of these planets are full of water, but we can dream, can’t we?
Other Earths are out there.
Kepler’s survey has made it possible for us to measure the number of Earth-size habitable zone planets in our galaxy. Determining how many planets like our own that exist is the big question we’ll explore next.
The hunt for new planets continues.
Kepler continues to search for planets in different regions of space. With the launch of our Transiting Exoplanet Survey Satellite (TESS) and the James Webb Space Telescope (JWST) in 2018, we’re going to search for planets nearest the sun and measure the composition of their atmospheres. In the mid-2020s, we have our sights on taking a picture of small planets like Earth with our Wide-Field Infrared Survey Telescope (WFIRST).

The wonders of Mars
1,000 Days in Orbit: MAVEN’s Top 10 Discoveries at Mars
On June 17, our MAVEN (Mars Atmosphere and Volatile Evolution Mission) will celebrate 1,000 Earth days in orbit around the Red Planet.
Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars. MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.
Here’s a countdown of the top 10 discoveries from the mission so far:
10. Unprecedented Ultraviolet View of Mars
Revealing dynamic, previously invisible behavior, MAVEN was able to show the ultraviolet glow from the Martian atmosphere in unprecedented detail. Nightside images showed ultraviolet “nightglow” emission from nitric oxide. Nightglow is a common planetary phenomenon in which the sky faintly glows even in the complete absence of eternal light.
9. Key Features on the Loss of Atmosphere
Some particles from the solar wind are able to penetrate unexpectedly deep into the upper atmosphere, rather than being diverted around the planet by the Martian ionosphere. This penetration is allowed by chemical reactions in the ionosphere that turn the charged particles of the solar wind into neutral atoms that are then able to penetrate deeply.
8. Metal Ions
MAVEN made the first direct observations of a layer of metal ions in the Martian ionosphere, resulting from incoming interplanetary dust hitting the atmosphere. This layer is always present, but was enhanced dramatically by the close passage to Mars of Comet Siding Spring in October 2014.
7. Two New Types of Aurora
MAVEN has identified two new types of aurora, termed “diffuse” and “proton” aurora. Unlike how we think of most aurorae on Earth, these aurorae are unrelated to either a global or local magnetic field.
6. Cause of the Aurorae
These aurorae are caused by an influx of particles from the sun ejected by different types of solar storms. When particles from these storms hit the Martian atmosphere, they can also increase the rate of loss of gas to space, by a factor of ten or more.
5. Complex Interactions with Solar Wind
The interactions between the solar wind and the planet are unexpectedly complex. This results due to the lack of an intrinsic Martian magnetic field and the occurrence of small regions of magnetized crust that can affect the incoming solar wind on local and regional scales. The magnetosphere that results from the interactions varies on short timescales and is remarkably “lumpy” as a result.
4. Seasonal Hydrogen
After investigating the upper atmosphere of the Red Planet for a full Martian year, MAVEN determined that the escaping water does not always go gently into space. The spacecraft observed the full seasonal variation of hydrogen in the upper atmosphere, confirming that it varies by a factor of 10 throughout the year. The escape rate peaked when Mars was at its closest point to the sun and dropped off when the planet was farthest from the sun.
3. Gas Lost to Space
MAVEN has used measurements of the isotopes in the upper atmosphere (atoms of the same composition but having different mass) to determine how much gas has been lost through time. These measurements suggest that 2/3 or more of the gas has been lost to space.
2. Speed of Solar Wind Stripping Martian Atmosphere
MAVEN has measured the rate at which the sun and the solar wind are stripping gas from the top of the atmosphere to space today, along with details of the removal process. Extrapolation of the loss rates into the ancient past – when the solar ultraviolet light and the solar wind were more intense – indicates that large amounts of gas have been lost to space through time.
1. Martian Atmosphere Lost to Space
The Mars atmosphere has been stripped away by the sun and the solar wind over time, changing the climate from a warmer and wetter environment early in history to the cold, dry climate that we see today.
Maven will continue its observations and is now observing a second Martian year, looking at the ways that the seasonal cycles and the solar cycle affect the system.

This is Floria, the planet that Beauhi visits a lot. It is a circumbinary planet, which means it orbits two suns. It is a fairly large planet and is full of vegetation. Even some species of animals on Floria are similar to Some plants, some of which are found on earth. Though they aren’t nearly as large on earth as they are on Floria.
You know that story of the Russian cosmonaut? So, the cosmonaut, He's the first man ever to go into space. Right? The Russians beat the Americans. So he goes up in this big spaceship, but the only habitable part of it's very small. So the cosmonaut's in there, and he's got this portal window, and he's looking out of it, and he sees the curvature of the Earth for the first time. I mean, the first man to ever look at the planet he's from. And he's lost in that moment. And all of a sudden this strange ticking... Begins coming out of the dashboard. Rips out the control panel, right? Takes out his tools. Trying to find the sound, trying to stop the sound. But he can't find it. He can't stop it. It keeps going. Few hours into this, begins to feel like torture. A few days go by with this sound, and he knows that this small sound... will break him. He'll lose his mind. What's he gonna do? He's up in space, alone, in a space closet. He's got 25 days left to go... with this sound. So the cosmonaut decides... the only way to save his sanity... is to fall in love with this sound. So he closes his eyes... and he goes into his imagination, and then he opens them. He doesn't hear ticking anymore. He hears music. And he spends the sailing through space in total bliss... and peace.

Cooper : You don't believe we went to the Moon?
Ms. Kelly : I believe it was a brilliant piece of propaganda, that the Soviets bankrupted themselves, pouring resources into rockets and other useless machines...
Cooper : Useless machines?
Ms. Kelly : And if we don't want to repeat of the excess and wastefulness of the 20th Century then we need to teach our kids about this planet, not tales of leaving it.
Cooper : You know, one of those useless machines they used to make was called an MRI, and if we had any of those left the doctors would have been able to find the cyst in my wife's brain, *before* she died instead of after, and then she would've been the one sitting here, listening to this instead of me, which would've been a good thing because she was always the... calmer one.

A rocky planet discovered within the habitable area of the star nearest to our Sun may be covered with oceans.
The planet, named Proxima b, may be an ocean planet similar to earth.
In fact, it may even be the first exoplanet (outside of our Solar System) to be visited by robots from Earth in time.

Top 10 Star Trek Planets Chosen by Our Scientists
What would happen if the crew of the Starship Enterprise handed over the controls to our scientists and engineers? It turns out many are avid Star Trek fans with lengthy itineraries in mind.
1. Vulcan
What is perhaps the most famous Star Trek planet was placed by creator Gene Roddenberry in a real star system: 40 Eridani. This trinary system of three dwarf stars, about 16 light-years from Earth, could play host to exoplanets; none have been detected there so far. The most massive is 40 Eridani A, chosen as Vulcan’s sun.
2. Andoria
An icy “M-class” (Star Trek’s term for “Earth-like”) moon of a much larger planet—a gas giant—that is home to soft-spoken humanoids with blue skin, white hair and stylish antennae. In our solar system, gas giants play host to icy moons, such as Jupiter’s Europa or Saturn’s Enceladus, that possess subsurface oceans locked inside shells of ice. Our missions are searching for lifeforms that might exist in these cold, dark habitats.
3. Risa
Another Trek M-class planet known for its engineered tropical climate and its welcoming humanoid population. The planet is said to orbit a binary, or double, star system—in Star Trek fan lore, Epsilon Ceti, a real star system some 79 light-years from Earth. The first discovery of a planet around a binary was Kepler-16b, which is cold, gaseous and Saturn-sized.
4. “Shore Leave” planet, Omicron Delta region
This is another amusement park of a planet, where outlandish characters are manufactured in underground factories straight from the crew members’ imaginations. In real life, astronauts aboard the International Space Station print out plastic tools and containers with their own 3-D printer.
5. Nibiru
“Star Trek: Into Darkness” finds Captain Kirk and Dr. McCoy fleeing from chalk-skinned aliens through a red jungle. Red or even black vegetation could exist on real planets that orbit cooler, redder stars, an adaptation meant to gather as much light for photosynthesis as possible. An example may be Kepler-186f, a planet only 10 percent larger than Earth in diameter. At high noon, the surface of this planet would look something like dusk on Earth.
6. Wolf 359
A star best known in the Star Trek universe as the site of a fierce battle in which a multitude of “Star Trek: Next Generation” ships are defeated by the Borg. But Wolf 359 is a real star, one of the closest to Earth at a distance of 7.8 light-years. Wolf 359 is also a likely observational target for the Kepler space telescope in the upcoming Campaign 14 of its “K2” mission.
7. Eminiar VII/Vendikar
These two planets are neighbors, sharing a star system. So, of course, they’ve been at war for centuries. While we have no signs of interplanetary war, multiple rocky worlds have been discovered orbiting single stars. A cool dwarf star called TRAPPIST-1 is orbited by three Earth-size planets; two have a chance of being the right temperature for liquid water, with possible Earth-like atmospheres.
8. Remus
The planets Romulus and Remus are home to the Romulan Empire (ancient Rome, anyone?), although Remus seemed to have gotten the raw end of the deal. Remus is tidally locked, one face always turned to its star. Tidally locked worlds might well be a real thing, with many possible candidates discovered with our Kepler space telescope. The habitable portion of the surface of such planets might be confined to a band between the day and night sides called the “terminator zone”—a.k.a. the twilight zone.
9. Janus VI
A rocky world lacking an atmosphere, perhaps similar to Mars. While humans must maintain an artificial underground environment to survive, the innards of the planet are a comfortable home to an alien species known as the “Horta.” Their rock-like biochemistry is based on silicon, rather than carbon, inspiring us to imagine the many forms life might take in the universe.
10. Earth
In the Star Trek universe, Earth is home to Starfleet Headquarters; the real Earth is, at least so far, the only life-bearing world we know. No true Earth analogs have been discovered among the real exoplanets detected so far. But a new generation of space telescopes, designed to capture direct images of exoplanets in Earth’s size range, might one day reveal an alternative “pale blue dot.”

Review: The Martian (2015)
Rating: 9.5 of 10
Space is dangerous, but it's also endearing.
Never the fact has ever been more apparent in the movies, than in The Martian. Set in the near future, The Martian is about a group of astronauts in the early days of human exploration on the Red Planet who were forced to leave because of a heavy storm--leaving one of its members, Mark Watney (Matt Damon), on the surface. For months, intelligence and ingenuity were the only things keeping him alive until he could be rescued.
The Martian, for me, was an important movie because it showed what being an astronaut really is about. Space is a dangerous thing, and the movie never downplay on that, but The Martian also puts space in an endearing light that makes us never wonder why did we ever go to space in the first place. Because the answer will always be: why not? Why not be the first? Why not find out, for the greater human race? For anyone intimate with space travel, when Watney gave lecture about being an astronaut and basically says, "When you're up there, at some point you're gonna think you're gonna die and maybe you will," you know that it's 100% true but you also know that doesn't mean you don't wanna go up there in a heartbeat. It's hard to depict a balanced portrayal about the dangers of space, but The Martian nailed it.
Science is also definitely the hero in this film, which is a surprisingly rare occurrence in popular fiction. Not only did Watney repeatedly was shown applying basic science concept to solve his problem, the film also pretty accurately depicted the workings of NASA; how astronauts, ground control, and teams of scientists work hard and thoroughly to reach a common goal. Aside from being very capable, scientists and astronauts in this film were also pretty humorous--and it's important because real scientists love their jokes too, but are almost never depicted as such. It's a very science-positive movie and I appreciated it.
At one point in the movie, Matt Damon's character, who was a botanist exclaimed, "Mars will come to fear my botany powers!" asserting his conviction to grow food on the surface of Mars--something that hadn't been done by any humans before, ever. That, among many other scenes in the movie, was a clear example of the giddiness, humor, and determination of scientists existed in the film.
But in the very core of the movie, The Martian is about human’s determination to live, that everyone can relate to.
The Martian also nailed it with the casting. Matt Damon has the perfect charisma and cockiness about him, but I mostly want to commend the casting choices for the other characters. The most prominent members of the space crew were women (Jessica Chastain, Kate Mara), and at least half of other supporting characters were of minorities (of African, Chinese, Mexican, and Indian descent). Hollywood movies about space can too frequently feel a bit jingoistic (with NASA obviously being an American organization), but The Martian never felt like that the slightest. From the start, The Martian is a humanistic effort.
Directed by veteran director Ridley Scott (Alien, Blade Runner, Prometheus, Black Hawk Down), The Martian looked beautiful, and the movie flowed beautifully as well. The threats were terrifying as hell, and there were no fake or newfangled technologies so everything stayed grounded. But despite all the hardship Watney was against, it’s a strangely hopeful film.
TL;DR The movie is an obvious bait for people like me--who loves movies, space, and science in the equal amount--but it's also a damn good thriller about survival that everyone could enjoy.
