What’s Up for June 2017?

Have a planet party and compare Saturn and Jupiter! We’ll show you where and when to point your telescope or binoculars to see these planets and their largest moons. 

image

Meet at midnight to have a planetary party when Jupiter and Saturn are visible at the same time!

image

The best time will be after midnight on June 17. To see the best details, you’ll need a telescope.

image

Saturn will be at opposition on June 14, when Saturn, the Earth and the sun are in a straight line.

image

Opposition provides the best views of Saturn and several of its brightest moons. At the very least, you should be able to see Saturn’s moon Titan, which is larger and brighter than Earth’s moon.

image

As mentioned earlier, you’ll be able to see Jupiter and Saturn in the night sky this month. Through a telescope, you’ll be able to see the cloud bands on both planets. Saturn’s cloud bands are fainter than those on Jupiter. 

image

You’ll also have a great view of Saturn’s Cassini Division, discovered by astronomer Giovanni Cassini in 1675, namesake of our Cassini spacecraft.

image

Our Cassini spacecraft has been orbiting the planet since 2004 and is on a trajectory that will ultimately plunge it into Saturn’s atmosphere on September 15, 2017, bringing the mission to a close. 

image

Our Juno spacecraft recently completed its sixth Jupiter flyby. Using only binoculars you can observe Jupiter’s 4 Galilean moons - Io, Callisto, Ganymede and Europa.

Solar System: 5 Things To Know This Week

Solar System: 5 Things To Know This Week

This month you can catch a rare sight in the pre-dawn sky: five planets at once! If you look to the south (or to the north if you’re in the southern hemisphere) between about 5:30 and 6 a.m. local time you’ll see Mercury, Venus, Saturn, Mars and Jupiter lined up like jewels on a necklace. They’re beautiful in the sky, and even more fascinating when you look closely.

This week we’re taking a tour of the planets with recent information about each:

1. Artistic License

Solar System: 5 Things To Know This Week

Craters on Mercury are named for writers and artists of all kinds. There are Tolstoy, Thoreau and Tolkien craters, for example, as well as those that bear the names of the Brontës, photographer Dorothea Lange and dancer Margot Fonteyn. See the complete roster of crater names HERE.

2. Lifting the Veil of Venus

Solar System: 5 Things To Know This Week

A thick covering of clouds made Venus a mystery for most of human history. In recent decades, though, a fleet of robotic spacecraft has helped us peer past the veil and learn more about this world that is so like the Earth in some ways — and in some ways it’s near opposite.

3. Curious?

Solar System: 5 Things To Know This Week

Have you ever wanted to drive the Mars Curiosity rover? You can take the controls using our Experience Curiosity simulation. Command a virtual rover as you explore the terrain in Gale Crater, all using real data and images from Mars. Try it out HERE.

4. Now That’s a Super Storm

Solar System: 5 Things To Know This Week

Winter weather often makes headlines on Earth — but on Jupiter there’s a storm large enough to swallow our entire planet several times over. It’s been raging for at least three hundred years! Learn about the Great Red Spot HERE.

5. Ring Watcher

Solar System: 5 Things To Know This Week

This week, the Cassini spacecraft will be making high-resolution observations of Saturn’s entrancing rings. This is a simulated look at Saturn, along with actual photos of the rings from the Cassini mission.

Vasculhando A Periferia Do Sistema Solar, O Telescópio Espacial Hubble Da NASA, Registrou Um Pequeno

Vasculhando a periferia do Sistema Solar, o Telescópio Espacial Hubble da NASA, registrou um pequeno e escuro satélite orbitando o Makemake, o segundo mais brilhante planeta anão congelado, depois de Plutão, localizado no Cinturão de Kuiper.

O satélite, designado de S/2015 (136472) 1 e apelidado de MK 2, é cerca de 1300 vezes mais apagado que o Makemake. O MK 2 foi visto a aproximadamente 20000 km de distância do planeta anão, e tem um diâmetro estimado em 160 km. O Makemake tem cerca de 1400 km de diâmetro. O planeta anão foi descoberto em 2005, e seu nome foi dado em homenagem à divindade da criação dos povos Rapa Nui da Ilha de Páscoa.

O Cinturão de Kuiper é um vasto reservatório de material congelado, resquício da formação do Sistema Solar a cerca de 4.5 bilhões de anos atrás, e o lar de alguns planetas anões. Alguns desses mundos possuem satélites conhecidos, mas essa é a primeira vez que se descobre um objeto companheiro do Makemake. O Makemake é um dos cinco planetas anões reconhecidos pela União Astronômica Internacional.

As observações foram feitas em Abril de 2015 pela Wide Field Camera 3 do Hubble. O Hubble tem uma capacidade única de observar objetos apagados perto de objetos mais brilhantes e uma esplêndida resolução, que permite que os astrônomos possam observar o brilho do satélite do Makemake. A descoberta foi anunciada no dia 26 de Abril de 2016 através de uma circular emitida no Minor Planet Electronic Circular.

A equipe que fez a observação usou a mesma técnica que foi utilizada para observar os pequenos satélites de Plutão em 2005, 2011 e 2012. Algumas buscas anteriores feitas no Makemake não tinham dado resposta alguma. “Nossas estimativas preliminares mostram que a órbita do satélite parece estar de lado, e isso significa que quando você observa o sistema, você pode as vezes perder o satélite de vista, pois ele mergulha no brilho muito maior do planeta anão”, disse Alex Parker, do Southwest Research Institute em Boulder, no colorado, que é o líder da equipe que analisou as imagens das observações.

A descoberta do satélite pode fornecer uma valiosa informação sobre o sistema do planeta anão. Medindo a órbita do satélite, os astrônomos podem calcular a massa do sistema e ter uma ideia sobre a sua evolução.

A descoberta desse satélite também reforça a ideia de que a maior parte dos planetas anões possuem satélites.

“O Makemake é da mesma classe dos raros objetos parecidos com Plutão, então encontrar um satélite ali é muito importante”, disse Parker. “A descoberta desse satélite nos dá também a oportunidade para estudar o Makemake em maior detalhe”.

A descoberta desse satélite só aumenta cada vez mais a semelhança entre Plutão e o Makemake. Ambos os objetos já são conhecidos por serem cobertos por metano congelado. Como foi feito no caso de Plutão, ao se estudar mais a fundo o satélite, será possível revelar a densidade do Makemake, um resultado importante que indicará se a composição bruta de Plutão e do Makemake são também similares. “Essa nova descoberta abre um novo capítulo na chamada planetologia comparativa, uma maneira de se estudar a região externa do Sistema Solar”, disse Marc Buie, líder da equipe também do Southwest Research Institute em Boulder, no Colorado.

Os pesquisadores precisarão de mais observações do Hubble para fazer medidas precisas para determinar se a órbita do satélite é elíptica ou circular. As estimativas preliminares indicam que se o satélite tem um órbita circular, ele completa uma volta ao redor do Makemake a cada 12 dias.

Determinar a forma da órbita do satélite ajudará a responder questões sobre sua origem. Uma órbita circular e apertada do MK 2 indicará que ele foi o produto da colisão do Makemake com outro objeto do Cinturão de Kuiper. Se o satélite tiver uma órbita alongada, é mais provável que ele tenha sido capturado. Ambos os eventos teriam ocorrido a alguns bilhões de anos atrás quando o Sistema Solar era extremamente jovem.

A descoberta, pode também resolver mistérios do próprio Makemake. Estudos anteriores realizados no infravermelho, revelaram que enquanto a superfície do Makemake é inteiramente brilhante e muito fria, algumas áreas aparecem mais quentes que outras. Os astrônomos têm sugerido que essa discrepância pode ser devido ao fato do aquecimento de regiões discretas e escuras da superfície do Makemake. Contudo, a menos que o planeta anão tenha uma orientação especial, essas manchas escuras deveriam fazer o brilho do planeta anão variar substancialmente enquanto ele rotacionasse, mas essa variação no brilho nunca foi observada.

Esses estudos realizados em infravermelho anteriormente, não tinham resolução suficiente para separar o Makemake do MK 2. A reanálise da equipe, com base nas novas observações do Hubble, sugere que boa parte da superfície mais quente detectada anteriormente na luz infravermelha, na realidade, pode ser, simplesmente a superfície escura do seu companheiro, o MK 2.

Existem ainda algumas possibilidades que podem explicar por que o satélite teria uma superfície tão escura, mesmo orbitando um planeta anão que é brilhante como a neve fresca. Uma ideia é que diferente de objetos maiores, como o Makemake, o MK 2 é muito pequeno, de forma que ele não pode gravitacionalmente manter uma crosta congelada e brilhante, que sublima, mudando do sólido para o gás, quando iluminado pelo Sol. Isso faria com que o satélite fosse similar aos cometas e outros objetos do Cinturão de Kuiper, muitos dos quais são cobertos com um material muito escuro.

Quando o satélite Caronte de Plutão foi descoberto, em 1978, os astrônomos rapidamente calcularam a massa do sistema. A massa de Plutão era centenas de vezes menor do que a massa que foi originalmente estimada na época da sua descoberta em 1930. Com a descoberta de Caronte, os astrônomos repentinamente descobriram algo totalmente diferente sobre Plutão. “São esses tipos de medidas que a descoberta de um satélite permite fazer”, concluiu Parker.

This Is Not Just An Incredible View Of Earth, It’s Also A Fantastic Illustration Of The Terminator.

This is not just an incredible view of Earth, it’s also a fantastic illustration of the terminator. (No not that one!) The terminator is the moving line that separates the day side from the dark night side of a planetary body. From this vantage point you can make out the gradual transition to darkness that is experienced as twilight on the surface. This image was captured on Aug. 31 by astronaut Jeff Williams (@Astro_Jeff) while on board the ISS.

This New NASA/ESA Hubble Space Telescope Image Shows The Center Of The Lagoon Nebula, An Object With

This new NASA/ESA Hubble Space Telescope image shows the center of the Lagoon Nebula, an object with a deceptively tranquil name, in the constellation of Sagittarius. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.

O que vamos ter em dezembro de 2017!

What's Up - December 2017

What’s Up For December? Geminid and Ursid meteor showers & winter constellations!

image

This month hosts the best meteor shower of the year and the brightest stars in familiar constellations.

image

The Geminds peak on the morning of the 14th, and are active from December 4th through the 17th. The peak lasts for a full 24 hours, meaning more worldwide meteor watchers will get to see this spectacle.

image

Expect to see  up to 120 meteors per hour between midnight and 4 a.m. but only from a dark sky. You’ll see fewer after moonrise at 3:30 a.m. local time.

image

In the southern hemisphere, you won’t see as many, perhaps 10-20 per hour, because the radiant never rises above the horizon.

image

Take a moment to enjoy the circle of constellations and their brightest stars around Gemini this month.

image

Find yellow Capella in the constellation Auriga. 

image

Next-going clockwise–at 1 o'clock find Taurus and bright reddish Aldebaran, plus the Pleiades. 

image

At two, familiar Orion, with red Betelguese, blue-white Rigel, and the three famous belt stars in-between the two.   

image

Next comes Leo, and its white lionhearted star, Regulus at 7 o'clock.

image

Another familiar constellation Ursa Major completes the view at 9 o'clock.

image

There’s a second meteor shower in December, the Ursids, radiating from Ursa Minor, the Little Dipper. If December 22nd  and the morning of December 23rd are clear where you are, have a look at the Little Dipper’s bowl, and you might see about ten meteors per hour. Watch the full What’s Up for December Video: 

There are so many sights to see in the sky. To stay informed, subscribe to our What’s Up video series on Facebook. Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.

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.

image

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.

image

Out of the 219 new planet candidates, 10 are possibly rocky, terrestrial worlds 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.

image

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. 

image

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.

image

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.

image

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).
