We’ve selected two new missions to explore the early solar system. Lucy, a robotic spacecraft scheduled to launch in October 2021, is slated to arrive at its first destination, a main belt asteroid, in 2025. From 2027 to 2033, Lucy will explore six Jupiter Trojan asteroids. These asteroids are trapped by Jupiter’s gravity in two swarms that share the planet’s orbit, one leading and one trailing Jupiter in its 12-year circuit around the sun.

Psyche, targeted to launch in October 2023, will explore one of the most intriguing targets in the main asteroid belt–a giant metal asteroid, known as 16 Psyche. The asteroid is about 130 miles (210 kilometers) in diameter and thought to be comprised mostly of iron and nickel, similar to Earth’s core.

Cassini took so many jaw-dropping photos last year, how could anyone choose just 10? Well, the Cassini team didn’t. Here are 17 amazing photos from Saturn and its moons last year.
Impact craters have exposed the subsurface materials on the steep slopes of Mars. However, these slopes often experience rockfalls and debris avalanches that keep the surface clean of dust, revealing a variety of hues, like in this enhanced-color image from our Mars Reconnaissance Orbiter, representing different rock types.

Even though our New Horizons mission flew by Pluto in 2015, the scientific discoveries keep coming. Using a model similar to what meteorologists use to forecast weather and a computer simulation of the physics of evaporating ices, scientists have found evidence of snow and ice features that, until now, had only been seen on Earth.

Beauty of space
What’s Up for December? Mars and Neptune above the crescent moon and a New Year’s Eve comet!
2016 ends with fireworks as three planets line up as if ejected from a Roman candle. Mercury, Venus and Mars are visible above the sunset horizon all month long.
As Venus climbs higher in the sky, it looks brighter and larger than it appeared last month.
On New Year’s Eve, Mars and Neptune appear very close to each other. Through telescopes, rusty red Mars and blue-green Neptune‘s colors contrast beautifully.
There are two meteor showers this month – the Geminds and the Ursids. The best time to see the reliable Geminids will be next year, when the full moon won’t be so bright and interfering. This year, however, we may luck out and see some of the brighter meteors on the evening of the 13th and the morning of the 14th.
The best time to view the Ursids, radiating from Ursa Minor, or the little Dipper, will be from midnight on the 21st until about 1 a.m. on the 22nd, before the moon rises. They may be active on the 23rd and 24th, too.
We haven’t had a good easy-to-see comet in quite a while, but beginning in December and through most of 2017 we will have several binocular and telescopic comets to view.
The first we’ll be able to see is Comet 45P/Honda-Mrkos-Pajdušáková, which will appear low on the western horizon on December 15th. On that date, the comet will pass the pretty globular cluster M75.
By the 21st, it will appear edge-on, sporting a bluish-green head and a thin, sharp view of the fan-shaped tail.
On New Years Eve, the comet and the crescent moon will rendezvous to say farewell to 2016. A “periodic” comet is a previously-identified comet that’s on a return visit. Periodic comet 45P returns to the inner solar system every 5.25 years, and that’s the one that will help us ring in the new year.

Now that image special for St. Patrick's day
Is there a pot of gold at the end of a green aurora? Not sure, but these dancing green lights provide a spectacular view fitting for the St. Patrick’s Day holiday.
This stunning aurora was captured by NASA astronaut Jeff Williams during his 2016 mission on the International Space Station.
Even though auroras are best seen at night, they are actually caused by the sun. The sun sends us more than just heat a light…it sends lots of other energy and small particles toward Earth. The protective magnetic field around Earth shields us from most of the energy and particles. Sometimes, the particles interact with gases in our atmosphere resulting in beautiful displays of light in the sky. Oxygen gives off green and red light, while nitrogen glows blue and purple.

😥Poor Scrooge
Once again this episode is making me even more sad when i do these things.
Scrooge is still fuming after the argument on the plane with everyone.
Mrs. Beakley and Webby are leaving the manor with packed bags and uncertainty if they’ll come back. With Scrooge barely batting an eye and dismissing them quickly.
Webby is clearly still hurt after what Scrooge had said to her
“Well you’ve successfully pushed your family and everyone who cared about you away, Again. I hope your happy”. Dang, You can just hear the venom in her voice in that comment.
This freaking shot of duckworth leaving as well actually made me gasp in shock. I kinda forgot he was there but knowing that he was leaving to was heartbreaking.
Then we see Scrooge grab a key and go into a room which seems to be locked up for a long time due to the dust and the chair being covering up.
The realization slowly coming onto his face as he just sits there, contemplating the events. It quickly goes to mad then regret. (God this show is torturing me.)
Then we see that he did do what everyone thought he didn’t. He built more spaceships, he sent astronauts into space to look for her, with them never finding her ship or even losing the rescue ships in the process.
It was to the point of spending almost all of his money from his own bin to fund it and keep it going. But it got too expensive to the point where he was forced to shut it down completely, with Scrooge feeling like he failed to protect Della and try to bring her home and became truly alone in the process.
“I AM”
That line broke the dam whatever I was trying to hold in and had me silently sobbing as the credits rolled.
The way that line was acted, the gruff exterior of his stubbornness and his mind being made up and yet his voice sounds close to breaking as tears roll down his cheeks.
David Tennant…..it’s now the 2nd time this man has made me cry when I watch a show with him in it.
This Finale is gonna be amazing, but we all know we’re gonna be on the floor once it’s over.
One day humans will live on another earth-like planet that is safe for us.
There are infinite worlds both like and unlike this world of ours. We must believe that in all worlds there are living creatures and plants and other things we see in this world. – Epicurus, c. 300 B.C.
Are we alone? Are there other planets like ours? Does life exist elsewhere in the universe?
These are questions mankind has been asking for years—since the time of Greek philosophers. But for years, those answers have been elusive, if not impossible to find.
The month of October marks the 21st anniversary of the discovery of the first planet orbiting another sun-like star (aka. an exoplanet), 51 Pegasi b or “Dimidium.” Its existence proved that there were other planets in the galaxy outside our solar system.*
Even more exciting is the fact that astronomers are in hot pursuit of the first discovery of an Earth-like exoplanet orbiting a star other than the sun. The discovery of the so-called “blue dot” could redefine our understanding of the universe and our place in it, especially if astronomers can also find signs that life exists on that planet’s surface.
Astronomy is entering a fascinating era where we’re beginning to answer tantalizing questions that people have pondered for thousands of years.
Are we alone?
In 1584, when the Catholic monk Giordano Bruno asserted that there were “countless suns and countless earths all rotating around their suns,” he was accused of heresy.
But even in Bruno’s time, the idea of a plurality of worlds wasn’t entirely new. As far back as ancient Greece, humankind has speculated that other solar systems might exist and that some would harbor other forms of life.
Still, centuries passed without convincing proof of planets around even the nearest stars.
Are there other planets like ours?
The first discovery of a planet orbiting a star similar to the sun came in 1995. The Swiss team of Michel Mayor and Didier Queloz of Geneva announced that they had found a rapidly orbiting gas world located blisteringly close to the star 51 Pegasi.
This announcement marked the beginning of a flood of discoveries. Exotic discoveries transformed science fiction into science fact:
a pink planet
worlds with two or even three suns
a gas giant as light as Styrofoam
a world in the shape of an egg
a lava planet
But what about another Earth?
Our first exoplanet mission**, Kepler, launched in 2009 and revolutionized how astronomers understand the universe and our place in it. Kepler was built to answer the question—how many habitable planets exist in our galaxy?
And it delivered: Thousands of planet discoveries poured in, providing statistical proof that one in five sun-like stars (yellow, main-sequence G type) harbor Earth-sized planets orbiting in their habitable zones– where it’s possible liquid water could exist on their surface.
Now, our other missions like the Hubble and Spitzer space telescopes point at promising planetary systems (TRAPPIST-1) to figure out whether they are suitable for life as we know it.
Does life exist elsewhere in the universe?
Now that exoplanet-hunting is a mainstream part of astronomy, the race is on to build instruments that can find more and more planets, especially worlds that could be like our own.
Our Transiting Exoplanet Survey Satellite (TESS), set for launch in 2017-2018, will look for super-Earth and Earth-sized planets around stars much closer to home. TESS will find new planets the same way Kepler does—via the transit method—but will cover 400 times the sky area.
The James Webb Space Telescope, to launch in 2018, wil be our most powerful space telescope to date. Webb will use its spectrograph to look at exoplanet atmospheres, searching for signs of life.
We still don’t know where or which planets are in the habitable zones of the nearest stars to Earth. Searching out our nearest potentially habitable neighbors will be the next chapter in this unfolding story.
*The first true discovery of extrasolar planets was actually a triplet of dead worlds orbiting the remains of an exploded star, called a pulsar star. Two of three were found by Dr. Alexander Wolszczan in 1992– a full three years before Dimidium’s discovery. But because they are so strange, and can’t support life as we know it, most scientists would reserve the “first” designation for a planet orbiting a normal star.
** The French CoRoT mission, launched in 2006, was the first dedicated exoplanet space mission. It has contributed dozens of confirmed exoplanets to the ranks and boasts a roster of some of the most well-studied planets outside our solar system.

Awesome
After more than 12 years at Saturn, our Cassini mission has entered the final year of its epic voyage to the giant planet and its family of moons. But the journey isn’t over. The upcoming months will be like a whole new mission, with lots of new science and a truly thrilling ride in the unexplored space near the rings. Later this year, the spacecraft will fly repeatedly just outside the rings, capturing the closest views ever. Then, it will actually orbit inside the gap between the rings and the planet’s cloud tops.

The von Kármán Lecture Series: 2016
As the New Horizon’s mission headed to Pluto, our Chandra X-Ray Observatory made the first detection of the planet in X-rays. Chandra’s observations offer new insight into the space environment surrounding the largest and best-known object in the solar system’s outermost regions.
See Pluto’s X-Ray
When the cameras on our approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto’s largest moon, Charon, mission scientists knew two things: they’d never seen anything like it before, and they couldn’t wait to get the story behind it. After analyzing the images and other data that New Horizons has sent back from its July 2015 flight through the Pluto system, scientists think they’ve solved the mystery. Charon’s polar coloring comes from Pluto itself—as methane gas that escapes from Pluto’s atmosphere and becomes trapped by the moon’s gravity and freezes to the cold, icy surface at Charon’s pole.

The famed red-rock deserts of the American Southwest and recent images of Mars bear a striking similarity. New color images returned by our Curiosity Mars rover reveal the layered geologic past of the Red Planet in stunning detail.

Our Hubble Space Telescope recently observed a comet breaking apart. In a series of images taken over a three-day span in January 2016, Hubble captured images of 25 building-size blocks made of a mixture of ice and dust drifting away from the comet. The resulting debris is now scattered along a 3,000-mile-long trail, larger than the width of the continental U.S.

Another Earth? Or another home?
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).
